Bringing laser
to sunlight

Dr Dimitris Strakas

Dear colleagues,
Laser dentistry has long ago passed its years of baby steps and we are living the era that laser is already
part of modern dentistry modus alongside with other technological innovations and digital technologies.
The biggest and oldest scientific community that has united and served laser dentists since 1988 is
undoubtedly the World Federation for Laser Dentistry (WFLD). In the heart of this family, the European
Division (ED) has a significant part throughout the years. The 6th WFLD European Division Congress is here
and the beautiful city of Thessaloniki is waiting to host us in the country of sunlight, Greece.
We are more than delighted to discover that all forces of laser dentistry have contributed to this important scientific event, emphasising the fact that dentists from around the world are eager to participate and
discover the latest research and clinical projects from the most prominent opinion leaders. I am feeling also
honoured that for the first time all “major” companies in dental laser and restorative field have sponsored
this event and their presence will give us the opportunity to have a multicolour “palette” of wavelengths
and laser devices in the congress exhibition.
23 sponsors, 25 invited speakers, 70 oral presentations, 30 e-posters, a parallel aesthetic and CAD/CAM
congress on Saturday and eight free-of-charge workshops are ensuring a successful and informative
meeting. Moreover, the social events such as the Welcome Cocktail on the exhibition area and the Gala
Dinner will give you the opportunity to meet and reunite with colleagues from all over the world.
The 6th European Division Congress of the WFLD is opening its doors and welcomes you in the Makedonia
Palace hotel of Thessaloniki on 22 and 23 September. You are cordially invited to join us and indulge in two
days of science and socialising in the laser dental family.
Let’s meet in Thessaloniki! Let’s bring laser light to sunlight!
Sincerely,

Dr Dimitris Strakas
Chairman of WFLD-ED

Laser-supported
restorative dentistry
Authors: Prof. Dr Kosmas Tolidis & Dr Dimitris Strakas, Greece

Since the advent of laser in dentistry, one of the
most benefited disciplines alongside oral surgery is
restorative dentistry.
A plethora of existing wavelengths is providing
excellent, but most significantly, essential service in a
unique way. Starting from the visible light spectrum
(445 nm) going to red (660 to 670 nm), near-infrared
(810, 940, 980, 1,064 nm) up to the mid-infrared
spectrum (2,780 to 2,940 nm), a variety of clinical
situations can be dealt successfully, either with the
unique use of laser or a combination of conventional
approaches with laser. Numerous devices have been
developed, either on a single wavelength or more
versatile multiple diode laser devices with two or
even three different wavelengths adding ease of use
to clinical applications.
The purpose of this paper is to present an overview
of laser-supported restorative dentistry, going
through the available wavelengths and their different
applications and capabilities by using exemplary clinical cases.

The “blue laser”
Recently, Dentsply Sirona introduced the SiroLaser
Blue, a three wavelength device (445, 660, 970 nm)
aiming to respond to a variety of clinical conditions
requiring laser approach. As it is well known from the
absorption chart (Fig. 1), 445 nm is being highly
absorbed by melanin and haemoglobin establishing
this device as a very useful tool for surgery and
haemostasis.
In the field of restorative/operative dentistry, minor surgeries in the form of gingival contouring and
especially haemostasis are necessary, but a significant use, as it appears from early research data, can
also be light curing and energy provision to restorative materials. Composite resins and glass ionomers
can be light cured by the SiroLaser Blue device in a
very efficient way.
More in particular, conventional glass ionomer can
benefit from the energy provided by the laser and increase significantly their surface microhardness and

Gentle on surfaces.
Versatile in its use.
Third-generation laser technology: AdvErL Evo Er:YAG laser
Minimally invasive and flexible to use, the AdvErL Evo Er:YAG laser lets
you treat your patients extremely gently, thanks to the third-generation
laser technology which enables the maximum absorption of the laser
energy by water. It creates micro-explosions that are gentle on the tissue
and remove bacteria permanently. This high-tech instrument is thus ideal
for a wide range of indications across various disciplines – from periodontics
and endodontics to implants. Further advantages include the air and
water system integrated into the instruments, the user-friendly interface
with large color display, and the ergonomically designed handpiece.

resistance to dissolution. Therefore, alongside surgery, 445 nm has been proven a potent and efficient
wavelength when dealing with restorative materials.

The “soft” red
Dentine hypersensitivity
Dentine is a difficult and demanding dental tissue,
presenting certain difficulties in its management due
to its composite structure character. Alongside this
fact, certain clinical entities related to dentine morphology, structure and interrelation with other oral
tissues such as the gingiva are the root of difficult to
solve clinical problems.

is a strong, valid way for dentine hypersensitivity’s
management.
Dentine disinfection
Following caries excavation, a dental practitioner
is faced with dentinal walls still contaminated with
remaining bacteria either in a “soft” layer of carious
dentine or existing infiltrated inside dentinal tubuli.
Light-activated disinfection (LAD) or photo-activated
disinfection (PAD) are different names for the same
procedure. The foundations of this approach refer to
the use of a red laser in conjunction with a blue dye
(e.g. toluidine blue or methylene blue).

One of the major challenges in contemporary restorative dentistry is managing dentine hypersensitivity. Dentine hypersensitivity is a multifactorial
clinical situation that affects a significant number of
patients in almost all age groups. A variety of different
treatment modalities have been suggested, starting
from toothpastes and varnishes, going up to restorative procedures.

In principle, the red light activates the dye in order
to produce free oxygen radicals, a very potent disinfectant that would disinfect dentinal walls without
affecting pulp’s vitality or interfering with adhesive
procedures and bond strength of contemporary
bonding systems and materials. The same method
is also being suggested for periodontal pockets
and root canal disinfections following similar procedures (Fig. 2).

Low Level Laser Therapy (LLLT) seems to be a key way
to manage these problems, especially in cases where
there is no space available for the placement of “permanent” coverings. Patients are coming in, exhibiting
different pain levels when thermal stimuli are applied,
in particular cold ones.

Subsequently, the red light “soft” laser can be useful in a variety of restorative cases providing either
immediate pain relief in some difficult cases, or a
safe environment for our restorative materials to
function, providing extended longevity of restorations.

The application of a “soft” laser (0.2 to 0.5 W, cw)
for one to two minutes at the cervical area of each
tooth provides an effective treatment in most cases.
Certainly, because of the multifactorial character of
the problem, there are cases that perhaps would
respond positively on a different approach. But laser

The “diode laser”
Diode laser devices at 810, 940 and 980 nm can be
also referred to as the “standard” diode devices found
in almost every laser equipped dental clinic. These
wavelengths are the most common wavelengths

Concurrently, at the same range of the electro
magnetic spectrum and in particular at 655 nm laser
caries detection device has been developed. Dental
decay lesion’s diagnosis and risk evaluation is the
corner stone of modern operative dentistry and the
minimally-invasive approach. Accurate detection of
site, extent and activity of the lesion is of paramount
importance, in our effort to provide quality treatment
to our patients. DIAGNOdent system utilises the
principle of “laser fluorescence” in order to detect and
classify decay lesions. Numerous research papers
have shown that this is a valid alternative in the caries
examination armamentarium. It exhibits clinically
adequate ability to “probe” difficult to access areas,
such as, pits and fissures and offer practitioners an
extra objective aid to examine and evaluate suspicious areas, promoting minimally-invasive restorative treatment.

for a numerous different everyday clinical cases
(surgical, endo, perio, bleaching, etc.), with significantly reduced prices compared to other alternatives.
In restorative dentistry in particular, the diode laser
can be used for the minimal gingival retouch near
cavity margins (Fig. 3), haemostasis and gingival
troughing before a restoration or impression taking
as well as for bleaching procedures used always in
combination with the respective bleaching agents
and handpieces (Fig. 4). Especially in cases where
gingival and bleeding management is crucial, these
devices can provide a safe and predictable result
much quicker than conventional approaches. De-

The erbium family laser devices (Er:YAG and
Er,Cr:YSGG) are the protagonists in the restorative
dentistry palette. Thus, they can be referred to as the
“Swiss Army Knife” as they can perform all needed
actions related to procedures in modern restorative
dentistry. These results are based on the fact that erbium lasers are highly absorbed in water, a compound
existing in variable amounts, in all human tissues.
Their only significant drawback that limits their
use in a dental surgery is their relatively elevated price
in the market. It goes without saying, of course, that
as in all laser instances, prior to the acquisition and
use of such devices a proper, well-structured and
documented education and training is essential.
The erbium family laser devices can successfully
perform all procedures both on soft and hard oral
tissues. With the respective parameters and settings,
an erbium family laser can manage gingival contouring and modelling (most of the times without the
need for anaesthesia) and then proceed to cavity
preparation in a clinically acceptable time span.
The cavity preparation is a less frustrating procedure for the patient as it lacks major issues of the
conventional approach, for example anaesthesia,
noise, vibrations, pressure, etc. (Fig. 5). Even when
getting close to the pulp or on minor directly manageable pulp exposures, with the use of the appropriate settings, a pulpal “bandage” can be achieved in a
safe way (Figs. 6–8).

[11] =>

Figs. 6–8: With the use of the
appropriate settings,
a pulpal “bandage” can be achieved
in a safe way.

Fig. 7

The main characteristics of the cavity are the
same as with the conventional approach, rendering
possible the restoration with all available restorative
techniques and materials. The only significant difference that should be taken into consideration is
that laser cavity preparation is a “smear layer free”
restoration.
Erbium family laser light is eliminating smear layer
on enamel and especially on dentine, and currently
this is an issue of research as for the pH of the bonding
systems that should be used on such a surface. The
findings, so far, suggest that self-adhesive systems
exhibit better results than total-etch systems.

Conclusion
In conclusion, laser in dentistry has long now
passed adolescence and has entered a period of maturity. Dentists start to appreciate the quality of
treatment they can provide to their patients, and applications of diode lasers are growing significantly.
The erbium family lasers are strongly related to
price, but still the interest shown proves that when
they would become affordable for bigger numbers of
practitioners then there would be a generalised use,

something like the introduction of high-speed turbines some decades ago.
Still, we need to stress the point that the use of
either diode or erbium or any other type of laser
should be founded on a solid, well-structured, documented education and training, assuring the safety
of both patients and dental professionals._

Kurz & bündig
Seit dem Aufkommen von Lasergeräten in der Zahnheilkunde profitiert die Restaurative Zahnheilkunde, neben
der Oralchirurgie, am stärksten von dieser Technologie. Eine Vielzahl existierender Wellenlängen liefern einen wichtigen Beitrag für die Arbeit am Patienten. Angefangen bei einem sichtbaren Lichtspektrum (445 nm) über ein Rot(660 – 670 nm), Nah-Infrarot- bis hin zu einem mittleren Infrarot-Spektrum (2.780 – 2.940 nm) können unterschied
liche klinische Situationen erfolgreich behandelt werden – entweder durch die alleinige Verwendung eines Lasers oder
eine Kombination aus konventionellen Ansätzen und Laser.
Der Artikel gibt einen Überblick über die unterschiedlichen Lasertypen und -wellenlängen, die in der lasergestützten, Restaurativen Zahnheilkunde eingesetzt werden und erklärt anhand klinischer Fallbeispiele die unterschiedlichen
Anwendungsmöglichkeiten. Einer der am meisten genutzten Laser in der dentalen Praxis ist dabei der Diodenlaser.
Das vielseitigste, gleichzeitig aber auch teuerste Gerät ist der Erbiumlaser; er gilt als das „Schweizer Taschenmesser“
unter den Lasern. Für welches Gerät sich der Behandler auch entscheidet: Die Autoren betonen, dass in jedem Fall
eine solide, gut strukturierte und dokumentierte Ausbildung notwendig ist, um die Sicherheit sowohl von Patient als
auch Behandler sicherzustellen.

Maxillary frenectomy
with a diode laser
Author: Dr David L. Hoexter, USA

There are many opinions, both in favour of and
against, regarding utilisation of lasers in periodontal
therapy. There are also many reports of the different
surgical techniques utilising sharp metallic instruments for exacting predictable and desired results.
The use of a laser to achieve these results does not
mean that there are no other efficient, “classical”
procedures that would accomplish the goal. Yet, a
laser might be a more direct and efficacious path to
achieve the same goal, with easier healing and less
side effects.
This case presentation allows me to demonstrate
the utilisation of a diode laser to allow ease of technique, avoid unnecessary bleeding, avoid the use of
sutures (and their removal), and provide a comfortable transition for the patient without swelling or
need for a periodontal dressing after the surgery.

In this presentation, a young female patient presented in my office complaining about her frenum in
the maxillary anteriors. She related that it hurt whenever she bit into a firm substance, such as corn on the
cob. Her tongue constantly reached to this uncomfortable area, affecting her speech, and she felt pain in
her lip when she tried to smile. A few years prior, she
had a lot of dentistry done in her maxillary anteriors
for aesthetic purposes. She had been aware of and
bothered by a natural, large diastema between her

Fig. 2

Fig. 3

maxillary centrals. The previous dentist had closed the
diastemic space between the crowns by overbonding
the area, leaving overhanging margins on the mesial
of both centrals (Fig. 1). The area now appeared clinically closed, but the constant irritation and bleeding in
the area, especially due to the frenum pull, made this
teenage patient feel very uncomfortable.
X-rays taken by my office revealed an obvious
space, seen as a large radiolucent dark area between
both central incisor roots, covered with tissue (Fig. 2).
In this case, I made a decision to use a laser to do the
frenectomy because of the possibility that a classical
approach might result in leaving a large void between
the centrals. Moreover, use of a laser allows complete
control in this technique to avoid what might otherwise be a devastating disaster. If the natural, large
void between the centrals submarginally was to have
been exposed, it would have left a vast undesirable,
unaesthetic, dark-appearing hole.
Treatment with diode laser
Because this was a surgery that involved only softtissue, our choice of lasers is the CO2, Nd:YAG and
diode lasers. Other lasers may be used for both softand hard-tissue. I chose to utilise just a tissue laser,
and chose a diode laser. This diode laser also offered
the use of a disposable tip containing a thin fibre that
would transmit the therapeutic treatment. The tip,
being disposable, will aid in the consistency of maintenance and hygienic cleansing in and during our
treatment.
A standard frenectomy, where we might remove
the frenum with a sharp stainless steel instrument,
might lead to further complications by exposing the
large void pointed out in Figure 2 that is covered by
tissue. If the frenum is just incised and removed, the
area will have an obvious, huge, dark-appearing void.
Yet, the frenum should be removed. The obvious
restorative necessities and options were discussed
first. This young patient wished to do a little at a time,
starting with the frenum removal.

[13] =>

case report

After local anaesthesia with xylocaine, the frenum
was infiltrated, incised from the attachment of the
tissue and lip-side of tissue first, rather than incising
in the centre of the frenum or separating and detaching the tissue from the side attached to the alveolus.
Using the diode laser, the tissue was incised, keeping
the field of vision intact and accessible. Continuing
movement of the laser tip toward the alveolar-covered
tissue allows the trough to be made wider until the desired length is acquired. All of this is accomplished
painlessly, without a pool of blood blocking the view.
This laser automatically enhances a clot, allowing
not only a view but also a comfortable working environment for the operator as well as a painless one for
the patient. The assistant retracts the lip, with the
laser allowing complete vision and aiding in curtailing
the bleeding. After the tissue is dissected to the
desired level, the remaining loose tissue of the frenum
is removed using the diode laser, as well. These results
leave a slight charring when we wish to control bleeding (Figs. 4 & 5).
Postsurgery
Healing proceeds uneventfully until it is completed
and is maintainable (Fig. 6). Once the frenum is removed and healed, the patient is no longer uncomfortable when eating nor is her lip restricted when
she desires to smile. The healed area allows the patient
to keep the area clean. She is able to reach and floss
the mesial aspects, which she couldn’t do previously.
After completion, she is reminded of the need to correct the restorations of her maxillary anterior teeth
and get rid of the obvious overhanging margins.

Conclusion
This particular patient desired a little correction at a
time, but, in the meantime, the positive results of the
laser treatment made her positive about correcting and
improving the aesthetics of her anterior maxillary teeth

in the near future. With the use of this diode laser, we
are able to remove the frenum attachment from the lip
side initially, allowing a predictable approach that helps
avoid exposing a large hole in the very front and centre
of her smile. This laser treatment and its positive results
for her, allowed her to consider future restorative corrections with a positive attitude. In this case, use of the
diode laser allowed her smile to be corrected, and
changed her discomfort into a comfortable glow._

Der Artikel beschreibt den Fall einer jungen Patientin, die zur Behandlung eines Frenums im Oberkieferfrontzahnbereich
vorstellig wurde. Wenige Jahre zuvor wurde sie bereits wegen eines Diastema zwischen ihren Oberkieferfrontzähnen behandelt. Der damalige Zahnarzt schloss den diastemischen Spalt zwischen den Kronen durch Bonding, wobei er überhängende
Ränder im mesialen Bereich beider Zähne zurückließ. Obwohl das Areal klinisch geschlossen erschien, beeinträchtigte die
konstante Reizung und Blutung in diesem Bereich die Patientin sehr. Zur Beseitigung des Frenums wurde statt einer Standard-Frenektomie mit scharfen Edelstahlinstrumenten, die möglicherweise weitere Komplikationen zur Folge gehabt hätte,
eine Frenektomie mittels Laser durchgeführt. Hierbei fiel die Wahl auf den Diodenlaser, der sich besonders für die Weichgewebebehandlung eignet. Die Behandlung mit dem Diodenlaser erfolgte schmerzfrei und ohne große Mengen an Blut, die das
Sichtfeld des Behandlers blockiert hätten. Das Frenum konnte vollständig entfernt werden und der Heilungsprozess verlief
problemlos. Die unkomplizierte Laserbehandlung und das damit verbundene positive Ergebnis ermöglichen der Patientin,
auch in Zukunft restaurative Korrekturen in Betracht zu ziehen – mit einer positiven Erwartungshaltung.

Laser in second-stage
implant surgery
Authors: Dr Habib F. Zarifeh, M.Sc., Dr Mayssam Bachacha, MS & Dr Monique Hanna, MS, Lebanon

The usage of laser devices has provided less invasive
management options for dental procedures. Thereby,
the erbium laser is the most used laser in dentistry
nowadays. It presents the most application possibilities since it can be used on both soft- and hard-

tissues. When it comes to soft surgery, there are many
indications including gingivectomy, gingivoplasty,
sulcular debridement of diseased fibrous tissue1, lesion removal, fibroma removal, tissue retraction, aphthous ulcers, gingival hyperplasia (excision and recontouring), crown lengthening, operculectomy,
frenectomy, and photocoagulation.2
In addition, the erbium laser may be used for periodontal procedures3, including laser soft tissue
curettage, laser removal of diseased, infected, inflamed or necrotised soft tissue within the periodontal pocket, removal of highly inflamed oedematous
tissue affected by bacteria penetration of the pocket
lining and junctional epithelium4. In this article, we
present a case where the Er,Cr:YSGG laser was used
in a second-stage dental implant surgery.

Case presentation
A patient presented with dental implants previously inserted in the maxilla. Topical anaesthetic was
administered before the procedure for three minutes,
second-stage surgery was performed with an
Er,Cr:YSGG laser (Waterlase MD, Biolase Technology,
Inc., USA), using a Gold handpiece in S contact mode
Z6 tip (2.78 µm, 3 W, 50 Hz, water 30 %, air 15 %).
The settings for the procedure strictly followed the
manufacturer’s instructions.
Fig. 2

Discussion
Er,Cr:YSGG laser for soft tissue oral surgery is becoming widely used.5 It’s beneficial effects include
sufficient haemostasis, absence of swelling and pain
and precise incision margin.6

When in contact with the tissue, the laser light can
be reflected, scattered, be absorbed, or be transmitted
to the surrounding tissues.7 The presence of free water molecules in biological tissue are vaporised as they
absorb laser energy, causing the increase of intra-
tissue pressure, producing vapour within the tissue

and provoking “micro-explosions” that cause the
mechanical breakdown of tissues and physically contribute to the ablation process. The ablated surface
exhibits a microstructured appearance with minimal
thermal alteration.8

The peri-implant soft tissue is of major importance
in the upcoming prosthetic stages since the gingival
tissue attachment around implants is one of the factors of success of implant rehabilitation, especially in
aesthetic areas.12

In this laser, the photon amplification occurs
through a medium of heterogeneous crystal
(YSGG). This laser emits photons at 2,780 nm wavelengths and has a pulse duration of 140 to 600 µs in
the repetition rate that can vary from 10 to 50 Hz.
The major beneficial properties of lasers are their
relatively easier ablation of soft tissues than that of
mechanical instruments and their haemostatic and
bactericidal effects.

Conclusion

There are two surgical stages for conventional implant dentistry. The first stage consists of performing
the implant fixture while the second stage consist in
uncovering it. The second stage is less aggressive for
the patient comparing to the actual surgery but presents more pain.9
Dental implants can be exposed by using scalpel,
punch, electro surgery, or laser uncovering that decrease bleeding, swelling, and postoperative discomfort. Electrosurgery has frequently been employed
and is capable of easily incising soft tissues with good
haemostasis but unwanted thermal damage can
cause delayed wound healing.10, 11

The advantages for laser treatment include tech
nical simplicity, the possibility of obviating local anaesthesia, absence of postoperative pain and oedema
as well as predictable results and complete tissue
healing in several days, as it will facilitate rapid prosthetic rehabilitation._

Laser-assisted direct
pulp capping
Author: Pawel Roszkiewicz, Poland

The essence of conservative dentistry is conservative, that is, economical tissue management—
for both hard tissues and the protection of the
endodontium’s vitality. Deep cavities accompanied
by pulp exposure are, indeed, a huge challenge for
the pulp to preserve its vitality, but also for the dentist and treatment performed to increase, not decrease, the chance to save vital pulp for many years.
In case of very deep cavities, it is oftentimes indicated to perform an endodontic treatment. However, one should remember that the possibilities of
contemporary endodontics do not limit to complete cleaning of the root canals system and its tight
3-D filling, but offers other, less radical methods of
treatment. Endodontic treatment does not have to
be equal with “killing” the tooth. If the image of the
pulp seen in the microscope is correct, direct pulp
capping performed in aseptic conditions allows to
preserve the tooth's vitality.
If small serous effusion, small bleeding accompanying possible mechanical injury during cleaning stop by itself thanks to cleaning the chamber
with a piece of cotton wool soaked with NaCl, chlor
hexidine, or laser-assisted pulp protection, there
are good prognosis for biological treatment. If no
pulpitis occurs (the application of a rubberdam and
Class II to Class I cavities conversion are necessary),
when the pulp capping with MTA or Biodentine is
performed, the size of pulp exposure (in a reasonable

Case report
A 35-year-old patient was referred to our clinic
because of a deep cavity Class II (MO) in tooth 16.
Because of the cavity complexity and a desire to
avoid its complication—the pulp exposure, partially
cleaned cavity bottom was covered by non-hardening (UltraCal XS) and self-hardening (Ultra-Blend)
calcium hydroxide. Then, the cavity was filled with a
temporary filling. The patient did not report any pain,
and the sensitivity to stimuli was similar to other
molars in the maxilla.
Clinical findings
In order to assess the extent of the tooth core
damage and its chances for biological treatment,
a RTG photo of tooth 16 has been taken (Fig. 1). On
the photo we can see the radiological shadow indicating the presence of fillings on the occlusal surface. The radiological shadow in the medial part
of the chamber projection, not having its counterpart in this tooth's fillings, requires intraprocedural
differentiation by pumping calcium hydroxide or
dental dressing into the chamber.
In the chamber projection we can additionally observe thickened tooth structure, which suggests the
presence of denticles. Brightness in the area of roots
requires the differentiation between irreversible
pulpitis and congestion of the pulp as a response to
the calcium hydroxide use.

have a secondary meaning. Dried pulp, being a confirmation of its aseptic death, pus leak (at least part
of the pulp inflamed), heavy bleeding difficult to
stop (strong hyperaemia of the pulp, usually due to
the inflammation) are the situations when different
treatment protocols need to be used.

utes, confirming the theory about hyperaemia as
response to the calcium hydroxide application.

Cleaning with laser
In an articaine with epinephrine infiltration anaesthesia, by means of ultrasonic scaler, the temporary filling was partially removed in order to obtain the space required for the conversion the cavity
into Class I. Cleaning was continued with the use of
Er:YAG laser (LightWalker, Fotona), using the contact
contra-angle handpiece H14 with cylindrical optical
fibre with a diameter of 1.3 mm. The laser parameters
used during the procedure are presented on Figure 2
(cavity preparation) and Figure 5 (surface preparation for reconstruction).
The fibre tip of the contact contra-angle handpiece was carried out at some distance from the surface of the tooth (circa 1 mm). The wall of the cavity
was restored with the composite and the self-etching system. After the conversion into Class I cavity
and performing the occlusal adjustment, the rubberdam was applied and, from the tooth prepared in
such a way, all temporary filling was removed (using the scaler again) revealing the pulp exposure of
1 to 1.5 mm2 area in the buccal part of the cavity
bottom (Fig. 6). Delicate effusion of the colourless
and odourless fluid stopped after two to three min-

Treatment of hyperaemia
In the first stage of the treatment, the exposure
area was skipped, focusing on the remaining fragments of the cavity, continuing to clean it with laser on the previously mentioned parameters (Fig. 2).
In order to minimise the laser's impact on the pulp,
the deepest parts of the cavity were prepared using
the parameters modified to the values presented in
Figure 3. Once the dentine surface was cleaned, the
inner surface of the filling (unevenness between
dental dressing and metal matrix after condensation) was smoothed with the diamond turbine drill.
After preparation of the whole cavity, a piece of
the temporary filling previously pressed into the
chamber was removed by means of endodontic
hand tools (Figs. 6 & 7). The pulp behaviour during
the entire visit (correct pink colour of the visible
fragment of the pulp, small serous effusion without
anaerobic infection after the temporary filling removal, small pulp bleeding after removal of the foreign body from the chamber, and spontaneous termination of effusion and bleeding) resulted in, after
the patient gave his consent to the treatment plan,
an attempt to biological treatment.
Er:YAG laser was applied on the exposed pulp
(parameters shown in Figure 4) with the tip hold in
5 mm distance from the pulp in order to “defocus”
the beam (to reduce the intensity of radiation). Then,

the pulp was covered with Biodentine (Figs. 8–10).
After the time necessary for Biodentine to harden,
composite reconstruction of the occlusal surface
was prepared with the materials formerly used for
the reconstruction of the tooth wall (Fig. 11).
Posttreatment
The posttreatment radiographs of the tooth are
shown in Figure 12. The behaviour of the pulp during
the procedure gave a main reason to qualify it for
the conservative treatment and the observation (for
about three months). In comparison with analogical cavities treated with the use of Biodentine, but
without the use of laser, in the two years’ period of
observation (with a particular focus on the lack of
any ailments and discomfort after the anaesthesia stops), this case allows to expect tooth viability
maintenance and the standardisation of the peri
apical tissues image during the X-ray control.

Fig. 12

Conclusion
The use of laser increased control over the cleaning of the most damaged portions of the dentine
in order to prevent further exposure, or in case
they occur, reduce the associated risk for the pulp.
The application of laser in the preparation of the
exposed pulp makes reaching the state of homeostasis easier, additionally disinfecting the surface
layer of the pulp._

Using the AdvErL Evo laser
for endodontic treatments

ment methods. The only positive aspect I was able
to discern was faster wound healing.

from the product group of Er:YAG
lasers with an effective wavelength
of 2,940 nm.

In my opinion, this justified neither the high purchase price nor operating costs; and, so, I put the
question of using a laser in dental medicine to rest
as far as my own practice was concerned. And nothing caused me to change my opinion for the next
20 years. The much promoted revolution did not
come about, the ever so innovative laser quickly descended to esoteric marketing for dental practices,
whose only argument for a laser’s raison d’être was
that it conveyed the image of being a modern dentist.
My only points of contact with the medium were
limited to reading endodontic studies within the
scope of my own specialised endodontic practice.
For the most part, the abstracts confirmed a reduction in bacteria; however, this reduction was not
better in practical terms, perhaps even worse, than
that achieved with such fundamental measures as
irrigating with NaOCl.1, 2
Fig. 1

Introduction
I used a laser in a dental treatment for the first
time in 1991. I was completing my residency and my
superior had ordered a Nd:YAG laser to conduct PAR
therapies in his practice. But, truth be told, my very
first contact with a laser had actually taken place a
couple of years previously. In 1988, when I was still a
student at the University of Mainz, we were shown a
laser made by ADL and told that it was considered to
be the future of dental medicine. I was ambivalent
about that as I could not see the much praised advantages of using lasers because, contrary to the promises made about the equipment, treatments were
neither completely painless nor was the long-term
quality of the treatments better.
As a matter of fact, it was evident that treatments
using lasers in periodontology and dental surgery
took significantly longer than conventional treat-

laser

Moreover, the side effects of using a laser were mentioned as well, e.g. those caused by an excessive application of heat.3 All in all, I had no reason to concern
myself with the use of lasers in endodontics for more
than two decades, not to mention investing a considerable amount of money in this type of equipment.
Endodontics, by comparison, experienced enormous progress during this period of time.
The use of nickel-titanium (NiTi) as a material for
mechanical root canal instruments revolutionised
the preparation procedure and smoothed the path
for warm filling techniques. Electrical length measurements, dental microscopes and cone beam computed tomography (CBCT) became established, as
did the use of ultrasound for irrigation, preparation
of the primary and secondary access cavities, as
well as pin/fragment removal. Nonetheless, a critical
point throughout this time was the cleaning quality
of our preparation methods4, which remained an
unsolved problem in root canal treatments.

The Morita laser AdvErL Evo
At the annual conference of the German Society
for Endodontology and Traumatology (DGET) in
Hamburg in 2014, David Jaramillo spoke about the
so-called PIPS method using an Er:YAG laser.5 It
displayed outstanding results regarding the cleaning of root canals and dentinal tubules. This type of
laser application, which uses an Erbium:YAG laser
with an effective wavelength of 2,940 nm, is no
longer based on a direct thermal effect. Instead, endodontic irrigants are activated by small gas bubbles
that form at the tip of the laser due to heat. As they
move away from the tip, they cool down and collapse quickly. In this way, up to 50 bubbles per second are formed in quick sequence, forming a chain
of bubbles that streams through the irrigant, pressing it into the branches of the root canal system
and the dentinal tubules. Up until now, this had not
been possible in an adequate manner, irrespective
of whether activation was initiated with the help of
sound, ultrasound or the SAF system.
The micro-explosions are the key element of this
new treatment method. Micro-explosions occur
when the laser energy is absorbed by water and the
volume suddenly increases 800 to 1,000 times. This
causes the formation of very small bubbles, microbubbles, which collapse again just fractions of seconds later. The thermal effect, which is obligatorily
presupposed when a fluid acting as medium, is limited to a micrometer-thin layer on the root canal surface. Therefore, the exposure of tooth substance to
excessive thermal effects that has been observed
and feared with other laser applications is excluded.
I have been working with the Morita AdvErL Evo
(Fig. 1) in my practice since 2015. This laser also is
based on the principle of Laser-activated irrigation
(LAI) and uses the formation of microbubbles to
activate the irrigants, even if the term PIPS is not
used for reasons of patent law.
In the course of time, the Morita AdvErL Evo has
become an obligatory part of our treatment protocol, especially for the following procedures:

Fig. 2

and are used as part of my workflow (Fig. 2) in every
endodontic treatment. The P400FL tip (Fig. 3) is
designed for cleaning the trepanation cavity. Furthermore, in view of its diameter of 0.4 mm, length
of 13 mm and curved attachment, it allows instrumentation of the coronal and, if necessary, middle
sections of the root canal. The R300T tip (Fig. 4), which
has a diameter of 0.3 mm and a length of 16 mm, can
be used for accessing deeper areas of the root canal
after preparation has been completed.

Fig. 2: Clinical workflow of LAI within
the scope of endodontic procedures.

Clinical workflow of LAI within the
scope of endodontic treatments
Below I would like to describe in detail a clinical
workflow:
1. Cleaning the access cavity, representation of the
root canal entrances
After the initial dental trepanation, the P400FL tip
with 25 pps and 70 mJ is used. Dentine splinters,
which are pressed into the innumerable cracks and
pores during the preparation of the access cavity
and cannot be removed by conventional irrigation
methods, can be removed in this way. After just a few
seconds, the laser will have cleaned the access cavity

Fig. 3: The P400FL tip primarily is
used for cleaning the endodontic
access cavity as well as the upper
and middle sections of the canal.
Fig. 4: The R300T tip can also be
used deeper in the root canal and is
helpful when cleaning the middle and
apical sections of the canal.

1. Cleaning the access cavity, representation of the
root canal entrances.
2. Opening root canals, obtaining patency.
3. Removal of blockages.
4. Cleaning the root canals, removing the smear layer.
5. Removing calcium hydroxide, removing any foreign bodies.
Although the manufacturer offers a large selection of laser tips, two different tips have proven
particularly well suited for endodontic treatments

| industry
(Figs. 5 & 6). Any denticles will be detached from the
soft tissue surrounding them and rinsed out, any
soft- and hard-tissue will be removed from occult canal
entrances, making them visible and penetrable.
2. Opening root canals, obtaining patency
Using Morita’s AdvErL Evo will prove its worth
particularly in very narrow canals, which involve a
high risk of iatrogenic blockage. Morita’s AdvErL Evo
will rinse out the canals. Whereas the P400FL tip
(25 pps, 50 mJ) is used before the initial opening, the
R300T tip (25 pps, 50 mJ) is used for 20 seconds respectively after the coronal preparation of root canals. In this way, it will be significantly easier and
foreseeable to open up root canals completely with
thin manual instruments or mechanical glide-path
instruments up to the foramen apicale within the
meaning of the ‘patency’ concept. If the irrigation
solution exhibits slightly red colouring, this indicates that there may be a patency. If there is stronger
bleeding, even if it stops on its own just a short time
after the laser instrument is used, the energy parameter should be reduced from 50 to 30 mJ. In the same
way, periapical sensations of pain, which may occur
sporadically to a minor degree, can be considered a
sign that patency has been achieved and the energy
parameter should be reduced to 30 mJ.
3. Removal of blockages
If there are any blockages, as can frequently be the
case in revisions of the root canal filling, the P400FL
and R300T tips are used at 25 pps and 70 mJ and,
if necessary, with several irrigation cycles of 20 seconds respectively.

Figs. 5 & 6: The endodontic access
cavity can be cleaned efficiently with
Morita’s AdvErL Evo.

Fig. 5

4. Cleaning the root canals, removing the smear layer
Following the initial opening of the root canals
and the use of mechanical nickel-titanium instruments to complete the root canal preparation, if
necessary also intermittently during the preparation, Morita’s AdvErL Evo laser is used to remove the
smear layer analogous to conventional irrigation of
the root canals with irrigation solutions, ultrasound
or sound-activated irrigation.

Fig. 6

laser

3 2017

Then the R300T tip with 25 pps and 50 mJ is used.
The cloudiness of the irrigation solution after activation and the removal by rinsing of suspended
particles clearly demonstrates the efficiency of the
measures taken. This is particularly impressive if the
conventional irrigating methods mentioned above
were applied for the recommended duration in the
root canal and, nonetheless, the laser still removes
a smear layer from the root canal when it is applied
afterwards. The cloudiness of the irrigation solution
is a good indication for determining the duration of
irrigation, which can be ended when the irrigation
solution that is transported out of the root canal
seems to be clear. As a rule, this should be the case
after about 15–20 seconds.
In the event of bacterial infections, 3 % NaOCI is
used for the LAI; in the case of vital extirpation, 17 %
EDTA should be used.
5. Removing calcium hydroxide,
removing any foreign bodies
As helpful as calcium hydroxide may be when it is
used as an agent for disinfecting bacterially infected
root canals, it is also difficult to completely remove
this pasty material from root canals. Within the scope
of endodontic treatments, I insert calcium hydroxide
in the root canals as a medicinal filling after the mechanical preparation has been completed but before
the root canal filling is inserted. It remains there for
several days; in the case of large apical bright spots,
it may stay 12 to 16 weeks so that we can verify
by means of X-rays that reossification, a visible sign
of healing, has started before we fill the root canal.
Before filling the root canal (Figs. 7–9), the calcium
hydroxide has to be removed from the root canals.
To this end, the mechanical apical master file is used
to proceed up to 1 mm before reaching the working
length to be able to remove as much of the pasty calcium hydroxide as possible by using the instrument’s spiral-shaped teeth like a screw conveyor.
This is followed by a sound-activated irrigation
using an EDDY attachment (VDW). Each root canal
is rinsed for one minute with EDTA irrigation solution
and sound activation. Afterwards, an XP-endo
shaper instrument (FKG Dentaire) is used up to 1 mm
before reaching the working length; however, the
instrument is used less for preparation than for
cleaning the walls of the canals mechanically. It
seems reasonable to expect that there would be no
more calcium hydroxide after such a time- and material-intensive manner of proceeding. So, it is highly
impressive when Morita’s AdvErL Evo laser transports a surprisingly large quantity of remaining
calcium hydroxide out of the root canals. It is equally
impressive to see that irrigating with Morita’s AdvErL

Evo laser may, in certain cases, even bring to light
fractured foreign bodies such as fragments of
instruments or irrigation tips as well as old filling
material hidden in the depths of the root canals.

Summary and evaluation
Progress in endodontics can be measured by the
circumstance whether procedures are simplified or
more cost-effective than previously. Or whether one
can do something better. The Morita AdvErL Evo laser
helps us improve our treatment in the different stages
of a root canal procedure described above. Although
I still take a negative standpoint towards many statements made about the use of lasers, I have a positive
opinion about using an Er:YAG laser for LAI.
Critical aspects are the purchase price and the operating costs. The Morita AdvErL Evo laser is equipped
with comparably fracture-proof attachments; although this property is desired for the product, it is
not necessarily a matter of course in view of the alternatives that are available. Nonetheless, it must be
borne in mind that the laser attachments, being the
tools that they are, are subject to wear and, hence,
have a limited service life. For this reason, the purchase price, operating costs and time involved, need
to be taken into consideration when putting to-

Fig. 9

gether a viable economic concept. Unfortunately,
private health insurance schemes frequently refuse
to pay for LAI treatments, even though German legislation added such innovative measures to the
Schedule of Fees for Dentists. Of course, this is nothing new. For years, private health insurance companies refused to assume the material costs for disposable mechanical NiTi instruments or the costs for
using a dental microscope within the scope of endodontic treatments. We can only hope that legislation
will support the use of LAI in the near future. Irrespective of that, the practical benefits provided by
Morita’s AdvErL Evo laser are evident. For this reason,
using the Morita AdvErL Evo laser for LAI has proven
its worth as a meaningful and, hence, indispensable
treatment measure in all different phases of root
canal treatments and my endodontic work._

Kurz & bündig
Gegenüber konventionellen Methoden, die in der Endodontie bisher Verwendung fanden, schien der teure Laser für
den Autor nie einen Mehrwert zu bieten. In den vergangenen zwei Jahrzehnten hatte sich auf dem Gebiet der Endodontie
auch viel getan: NiTi als Material für mechanische Wurzelkanalinstrumente revolutionierten die Bearbeitungsprozeduren,
auch die elektronische Längenmessung, dentale Mikroskopie, DVT und Ultraschall wurden etabliert. Ein weiterhin un
gelöstes Problem stellte allerdings immer noch die Reinigungsqualität der Präparationsverfahren bei Wurzelkanalbehand
lungen dar. 2014 kam der Autor mit der sogenannten PIPS-Methode in Kontakt, bei der ein Er:YAG-Laser zum Einsatz
kommt. Diese Laseranwendung basiert nicht auf dem bis dahin gängigen thermalen Effekt, sondern auf Mikroexplosio
nen: Elektromagnetische Strahlung wird mit einer Wellenlänge von 2.940 nm, welche ideal durch Wasser absorbiert wird,
emittiert. Der Laserstrahl regt die Wassermoleküle an, wodurch diese ihr Volumen stark vergrößern und Mikroexplosionen
erzeugen. Auf diese Weise ist eine minimalinvasive und hitzearme Behandlung möglich. Seit 2015 arbeitet der Autor nun
mit dem Morita AdvErL Evo, welcher auf dem beschriebenen LAI-Prinzip (Laser-activated irrigation) beruht. Besonders
bei der Reinigung von Zugangskavitäten, der Eröffnung von Wurzelkanälen, der Entfernung von Verstopfungen, der Reini
gung von Wurzelkanälen sowie bei der Beseitigung von Calciumhydroxid und Fremdkörpern hat sich dieser Er:YAG-Laser
bewährt und ist ein hilfreiches Werkzeug in seiner endodontischen Arbeit geworden.

Increasing treatment quality
with two wavelengths
Ultradent Products Gemini 810 + 980 diode laser is the first and most powerful
diode laser for soft tissue treatment with two wavelengths. The Gemini can
use both wavelengths simultaneously: this dual wavelength technology combines melanin absorption at a wavelength of 810 nm and water absorption
at a wavelength of 980 nm. With an output of 20 watts, short but efficient
power phases are possible allowing the soft tissue to effectively cool down
during the procedure. Thus, super-pulsed energy reduces thermal damage
and increases patient comfort, as a result of reduced bleeding, inflammation
and pain, less need for sutures and a faster healing process.
The illuminated handpiece tip improves the practitioners view of the surgical
field. The Gemini fibre tips are pre-activated and may be bent to the required
shape. With its wireless Bluetooth foot switch the compact device provides
a maximum of flexibility. The innovative design incorporating a transparent
electroluminescent display does not only look good but is at the same time
very practical: the 19 pre-set programmes may be selected directly. The
displayed parameters can be altered when necessary.
Dentists can benefit from the innovative Gemini 810 + 980 diode laser as
it increases the quality and comfort of soft tissue surgery and with this
achieves a higher patient satisfaction.

Successful
communication
in your daily practice
Part III: Millennial patients
Author: Dr Anna Maria Yiannikos, Germany & Cyprus

Millennial patients
Let’s start with today’s challenging topic which is…
how to attract, communicate and retain millennial
patients, who are our present and future patients!
I will show you 7 crucial steps to always have in mind
when dealing with millennial patients.
First, who are the millennials? Millennials are those
patients that were born between 1980 and 2000, in
fact, the patients that are from 17 to 37 years old.
Because patients that belong to this age group are our
present and future clients, let’s start examining how
to attract them to come to our dental offices!

7 steps to attract millennials
In the following, I will teach you 7 steps of how to
attract millennials to come to your dental practice.

Welcome to the 3rd part of the
series “Successful communication
in your daily practice”. The series that
includes the most popular and
challenging scenarios that
might occur in your dental
practice and teaches you, how
to deal with them so that your
patients always leave your
practice feeling: “My dentist is
THE BEST!” Each individual article
of this series will teach you a new specialised protocol that you can easily
use, customise and adapt from the same day on to
your own dental clinic’s requirements and needs.
Step 1: Have a unique and intense online presence
The world wide web is an essential part of the
millennials’ life. With this in mind, you should spend
some time in creating a unique and attracting website and actively serve your social media channels.
The millennial patients are highly attracted by promo
actions, they love to check reviews, read about your
CSR (Corporate Social Responsibility) and your
philanthropic activities. Also be aware to have a
clear differentiation point and description of your
services—they pay a huge attention to all these tools
and points!
Step 2: Have a service-fighter
A service-fighter is a treatment, like for example
home bleaching, which is offered at the lowest price
in the market. This will help you to attract the interest
of those for whom price is very essential.

[27] =>

Step 3: Be honest and keep it short
While treating a millennial patient always remember to be honest, informative and brief! Millennials
hate it when you fool around with them. Also be as
informative as possible while in the same time keep it
short. Millennials are used to getting concentrated
information and thus they will double check what you
are telling them. They may have already googled it
before they came to you!

e-mail, SMS, WhatsApp or messenger with a brief but
at the same time detailed message about their current
health status and further treatment options.

It is also helpful to use some trigger words like
flexible, community, dynamic, friendly, stimulating,
environment. For example, you can say: “Our clinic
is environmentally friendly.” They will respect and
appreciate that because they are highly environmentally conscious themselves!

Just do it!

Step 4: Have a millennial employee
If you do not belong to the millennials’ age group, it
is of advantage to have at least one employee of your
team who does. You will see: Your millennial patients
will feel more comfortable to ask him or her possible
questions instead of you—and this is a fact!
Step 5: Use loyalty programmes
Millennials want to identify themselves with their
surroundings. This affects above all their health suppliers, amongst them you as their dentist! With loyalty
programmes you can offer them the possibility to
specially connect with your practice. Thereby, it is a
good idea to add your clinic’s loyalty programme to
your clinic’s mobile application (if you have one). They
will just love it as their mobile phones are their whole
life and something they always carry with them!
Step 6: No face-to-face communication
to follow-up
After a successful treatment, avoid to make a lot of
follow-up appointments with face-to-face-communication. Millennials rather love it short and simple, as
we have already learnt above. So better send them an

Step 7: Be fast
When you respond to your millennial patients, be
fast! Since they have grown up in a world where information is available in only short time, being fast is
notable and very important for them!

Imagine working for the next years and still have a
“full house” clinic because you know how to deal with
your millennial patients! Isn’t this just fabulous?
In the next issue of laser magazine, I will present to
you the fourth part of this unique new series of communication concepts that will teach you how to promote a service and/or technology before you apply it
in practice—5 unique steps that will guarantee the
increase of your patients’ interest!
Until then, remember that you are not only the dentist of your clinic, but also the manager and leader. You
can always send me your questions and request for
more information and guidance at dba@yiannikosdental.com or via our website www.dbamastership.com. Looking forward to our next trip of business
growth and educational development!_

Kurz & bündig
Millennials (17- bis 37-Jährige) sind die Patienten der Gegenwart und Zukunft. Im dritten Teil ihrer Serie erklärt
Dr. Yiannikos in 7 Schritten, wie Praxisbetreiber diese Patientengruppe erfolgreich ansprechen. Der erste Schritt führt
über eine ansprechende Website und umfassende Präsenz in Social-Media-Kanälen. Denn das World Wide Web ist ein
essenzieller Bestandteil ihrer Lebenswelt. Im zweiten Schritt empfiehlt die Autorin, einen speziellen Service (z. B. Home-
Bleaching) zum günstigsten, am Markt erhältlichen Preis anzubieten. Ehrlich, informativ und auf den Punkt gebracht –
diese drei Eigenschaften schätzen Millennials sehr und sollten bei der Behandlung unbedingt beachtet werden. Auch von
Vorteil ist es, wenn in der Praxis Mitarbeiter aus der Altersgruppe sind. Denn oftmals richten Millenials sich mit Fragen
lieber an ihre Altersgenossen. In Schritt 5 empfiehlt die Autorin, Bonusprogramme der Praxis mit der mobilen App (wenn
vorhanden) zu verknüpfen. Nach einer erfolgreichen Behandlung informiert die Praxis Patienten dieser Altersgruppe besser per E-Mail, SMS, WhatsApp oder Messenger über das weitere Vorgehen, statt Face-to-face-Kommunikation. Dabei
sollte sie schnell sein! Denn Millennials finden es wichtig und bemerkenswert, schnelle Rückmeldungen zu bekommen.

Laser as euphemism in
Paediatric Dentistry
Author: Dr Imneet Madan, UAE

As per the American Academy of Paediatric Dentistry
(AAPD), dental care is considered to be medically
necessary in order to prevent and eliminate orofacial
diseases, infections and pain. Anxiety towards dental
appointments has always been considered natural
and unavoidable. Keeping in mind this nature of
apprehension time and time again, several methods
of behaviour guidance have been introduced in order
to alleviate anxiety, provide dental treatment safely
and instil a positive dental attitude for lifetime.

What is dental fear?
Dental fear is defined as the specific anxiety which
is the predisposition for a negative experience in the
dental surgery.1 Dental fear in simple terms is described as the fear that any child would feel towards
its dentist, dental treatment or dental appointment in
general. Dental fear has been known to have several
roots of origin.

What gets measured, gets modified and corrected.
Keeping the same principles in mind, dental fear has
been graded by different rating scales. The most commonly used in the common practice is the Frankl
Behaviour Rating Scale. The Frankl Behaviour Rating
Scale grades fear as follows:
1. Definitely negative: refuses treatment, cries forcefully, extremely negative behaviour associated
with fear.
2. Negative: reluctant to accept treatment. Slight
negativism.
3. Positive: accepts treatment, can become uncooperative if experiences something negative.
4. Definitely positive: unique behaviour, looks forward to the treatment.

k.c

Parents who have had multiple dental problems and negative experience at the dentist
generally transpire these fears onto the kids
subconsciously and sometimes knowingly.
When kids finally arrive at the dental office,

Types of dental fear

Parental influence is one of the many factors that influence children’s behaviour at
the dental office. A positive parental attitude established in early life can directly
bring in a positive attitude for the kids.
According to the AAPD guidelines, every child should have the first dental
check-up at the age when the first tooth
erupts. This establishes a first contact
with the dental healthcare provider. Early
appointments also help to prevent the onset
of a dental disease, thereby decreasing the
treatment needs and opportunities for negative experiences.

they have a pre-formed image of the experience which
then decides their level of cooperation.

[29] =>

practice management

Another commonly used behaviour rating method
is by following clinical gradation:
–– Cooperative
–– Uncooperative
–– Apprehensive
–– Fearful
–– Obstinate

Phobia of needles
Children generally associate dental appointments with vaccination appointments with
doctors. They are highly phobic about needles. Any
treatment can be a nightmare with the underlying
fear of needles. The contemporary form of dentistry
is laser dentistry, which is needle free and child
friendly.

How does laser replace needles?
In case of fillings, the need for
numbing is completely ruled
The American Academy
outlines several ethical behaviour management techniques.
Apart from using these methods of behaviour management, one of the basic principles
that can be kept in mind is effective and positive result
oriented communication. The first step to gain the
child’s cooperation is to develop a proper rapport in
the first appointment. We generally use a special child
friendly language in order to gain the attention and
interest of the child in concern. This special language
of paediatrics is referred to as “euphemisms”.
Commonly used euphemisms are:
–– Laser: magic popping light
–– Needle: sleepy juice
–– Numbness: magic balloon
–– Cotton roll: cotton pillow
–– Handpiece: tickle brush
–– Suction: vacuum cleaner/sucker/Mr. Thirsty
–– X-ray: marshmallow picture
–– Mouth prop: tooth clip
Dental fear
Fear is one of the most constant limitations in the
paediatric practice. Children’s fear can sometimes
have a rational explanation and sometimes occur for
incomprehensible reasons. The solid foundation of a
rapport between child and paediatric dentist depends
on the actual acknowledgement of the child’s fear.
When we know that fear exists, the best way to overcome is to face it and resolve the cause.
Children’s fear of dentistry is generally related to the
words, tools, idea and concept of treatment. By keeping the first appointments only for check-up, X-rays
and cleaning, we are able to understand the treatment
needs, and the coping ability of the child. The child is
made aware of what the next steps can be in the
language of euphemisms. This way they go with the
eye opener of awareness of what to expect in the next
appointment. In case of long treatment appointments, generally the mornings are preferred as children are more fresh and receptive to instructions then.

out as the Erbium laser is a non-contact procedure.
Since there is no actual contact of tooth and laser,
there is no vibration or pressure on the tooth as in case
of drilling. This exempts the need for anaesthesia.
In a pre-procedural appointment, when the kids are
informed about playing Star Wars with sugar bugs
and not using any “injections”, their fear factor gets
significantly reduced. This helps them to overcome
the picture of dentistry as presumed before.
During the procedure, no numbing can help children to remain relatively relaxed, get the procedure
done and leave the practice after a short appointment with no sensation of numbness afterwards.
They can eat fifteen to twenty minutes afterwards
and parents do not have to worry about traumatic lip
or cheek bites.
What procedures can be done
without anaesthesia?
Regular restorative dentistry including all types of
cavities can be done easily without any need for injections. Pulp therapy such as pulpotomy, direct or indirect pulp-capping procedures and pulpectomy can be
performed with intrapulpal anaesthesia after pulp
exposure. In cases, where the child does exhibit apprehensive behaviour, minor infiltrations can be used.
Laser sealants have become quite popular in the
practice with a success rate much higher than the
normal sealants. The Erbium laser is used at Bond
prep: 3.35 Hz. This causes a slight enamel abrasion in
order to allow for a better mechanical bond between
seal and tooth surface. The normal cover period that
I consider in the practice for seals done this way is
about two years. The Erbium laser also helps to anaesthetise teeth externally. This itself can help to take
away the initial fear and get the procedure started.

How does this benefit appointment durations?
The appointment durations are much reduced as
there is no waiting period for anaesthesia. In addition,
multiple quadrant dentistry can be performed at the
same time. One appointment can be easily followed
by further consultations if needed with other specialists as the numbness barrier is removed.
How does laser increase
the value of time and chair occupancy?
Since the chairside time per patient can be reduced
with the use of laser, this certainly increases the value
of the practice as more patients can be accommodated in the fixed duration of hours.
Parental acceptance of laser vs drill
From the private practice point of view, lasers are
accepted in more than 90 % of all cases when proposed as treatment alternative. The cost difference
between a conventional drill and laser have been kept
at about 35 %. This enables more and more families
to avail the benefits of lasers for their little ones.
Cost benefit ratio
Even though lasers have been always looked up as
an expensive and add-on tool in many private practices, the advantages of lasers do certify the actual
return on investment from the very first year of the
investment. This increases the overall profit margin
for the company and thereby making lasers the all
round win situation for investor, dentist and certainly
for the patient.

Conclusion
In current times, we have come a long way doing
painless, needle-free dentistry. The bottom-line of
non-threatening and non-invasive dental care nevertheless remains at high-end prevention. The very fact
that the huge segment of child population does have
healthy teeth, does signify that dental disease can be
well avoided. The regular presence of children in the
practice, dietary advice and both primary and secondary levels of defence should be looked at.

Anxious children have been found to have a higher
risk of developing dental caries. To establish a healthy
foundation of paediatric surgery visitors, we must
work to convert dentally anxious children to cooperative dental patients. In order to accomplish this, we
need to commit ourselves to provide them with posi
tive experiences. The dental personnel should be
highly able to weigh benefits of a treatment vs psychological consequences of invasive dental treatments. While ruling out needles and numbness from
the practice, lasers do make the practice of Paediatric
Dentistry much more welcoming to families.
In conclusion, lasers as euphemisms are, indeed,
a great behaviour modification tool. An overall holistic approach with lasers does help to evade the fear
factor from children’s mind, keeping dental appointments simple for families._

Kurz & bündig
Angst ist einer der konstantesten Faktoren, welcher die zahnärztliche Behandlung von Kindern behindert. Gründe
für eine Zahnarztangst können unterschiedlicher Natur sein. Oftmals ist es der Einfluss der Eltern, der das kindliche
Verhalten in der Zahnarztpraxis positiv oder negativ beeinflusst. Mit verschiedenen Methoden der Verhaltensführung
lässt sich die kindliche Angst jedoch mildern. In einer ersten „Kennenlern“-Sitzung wird zunächst mittels Euphemismen eine positive, lösungsorientierte Kommunikation etabliert. So wird aus der Nadel „Schlafsaft“ oder aus dem
Absauggerät „Staubsauger“. Positive Erfahrungen sorgen dann dafür, dass Kinder eine dauerhaft positive Einstellung
zum Zahnarzt entwickeln können. Vor allem der Laser als „magisches Licht“ stellt dabei ein hilfreiches Tool innerhalb
der Kinderzahnheilkunde dar. Er ersetzt den Bohrer und beseitigt damit eine wichtige Quelle kindlicher Zahnarztangst.

Fire safety in
dental practice
Author: Stuart Collyer, UK

Being a dentist, you will be familiar with the need
to carry out regular checks on your patients to spot
potential problems before they become major
ones. This preventative approach should be applied
to your fire safety procedures and equipment too.
Just like any other business, complying with fire
safety regulations is an obligation. By carrying out
a fire risk assessment, you can secure the longevity
of your business by reducing the likelihood of a fire
starting, as well as preparing for the worst.
In fact, studies have shown that over 70 per cent
of businesses that have been involved in a major
fire either do not reopen or subsequently fail within
three years. Fire prevention is far easier than trying
to recover from a fire. More importantly, a fire risk
assessment ensures the safety of your staff and
patients. Thankfully, fully meeting the regulations
is not as dif ficult as one might expect, but failing
to do so comes with the risk of a large fine and
even a prison sentence.

The ﬁve stages of a ﬁre risk assessment
By completing a fire risk assessment, you will gain
a full understanding of your business in terms of the
activities that are carried out and the risks present. By
going through the five steps, you will have made your
dental surgery safer and compliant.
Step 1: Identify all potential combustibles and
possible sources of ignition.
Step 2: Consider all the relevant people who are
at greatest risk from fire.
Step 3: Remove or reduce the risks of fire as far
as possible and take precautions.
Step 4: Prepare for an emergency with fire safety
equipment, by providing correct training and by hav
ing a plan of which everyone is aware.

32

laser

3 2017

Step 5: Record any findings and regularly review
the assessment to keep it up to date.
The risk assessment should be recorded at all
stages, including the actions you have taken along
the way. If you hire five or more members of staff, it
is a requirement to have written proof that you have
fulfilled your duty as a responsible business owner.

Dental practice ﬁre hazards
For a fire to burn, it needs heat, fuel and oxygen.
With one or more of those elements removed, a fire is
instantly less likely to break out. Therefore, you need
to identify those items that can burn and potential
sources of a fire and keep them separated. Possible
sources that can cause a fire are radiographic and
other electrical equipment when they overheat, are
misused or are faulty. This can be avoided with regular
inspection and servicing by professionals. Heaters,
cooking equipment and smoking materials are other
risks. There is also the possibility of arson.
When looking around for potential fuel sources,
there are many to consider, including medical sup
plies, toiletries, aerosols, furniture, clothing, cleaning
products, and waste. In a dental practice, the oxygen
stored in cylinders can be a fire and explosion risk if
damaged or used incorrectly. It is therefore important
to take particular care in their use and storage.

Identify those at risk
The next step is to consider the people who could
potentially be present on your premises at the time of
a fire. Of course, this includes staff and patients, but
also take into consideration agency staff, contractors
and other visitors to your practice. There may be
particular individuals who would need assistance in
making a swift escape in an emergency. Those with
mobility issues, such as the elderly and disabled,
are particularly at risk, as are children. Think specifi

[33] =>

practice management

cally about the best way of getting those people
safely down any stairs. You may find that an evac
uation chair is vital, as is training staff in how to
use such equipment.

Evaluate and act
Having now identified all of the potential prob
lems and hazards that are present in your dental
surgery, you can now take the relevant action to
take precautions to reduce those risks as far as
practically possible. The most reliable solution is
installing fire detectors throughout the building
and using smoke and heat detectors, along with
call points, as part of a fire alarm system. When the
alarm sounds, fire exit signs will then direct people
to safety while emergency lighting illuminates
that route to keep people safe, no matter what.
Having the correct fire extinguishing equipment
installed throughout the premises is one of the best
ways you can prepare. Fire blankets in the kitchen
area will help tackle small fires with little mess or
hassle, while fire extinguishers are best in waiting
rooms, corridors, offices and treatment rooms. Wa
ter extinguishers are suitable for general fires, in
cluding paper, cardboard, rubbish and furnishings,
whereas foam extinguishers can be used for flam
mable liquids. Powder extinguishers are versatile,
lighter and safe to use around electrical equipment
and flammable liquid and gas. However, they can af
fect visibility and breathing, so should be mitigated
by a health and safety risk assessment if specified
for indoor use. On electrical equipment, carbon di
oxide extinguishers are the safest method and will
prevent further damage to the electronics.
Each extinguisher needs to be partnered with
an extinguisher identification sign and should
be commissioned upon installation and then
serviced annually by a trained professional.

You will need to select at least a few members of
staff you trust to take on fire warden responsibili
ties. Once they have received the appropriate train
ing, you should then have plenty to ensure there is
always a fire warden present in spite of sickness and
holidays. The purpose of fire wardens is to help ed
ucate the other staff, besides taking charge in the
event of an emergency. Their training will help them
to act appropriately and calmly in a fire situation
and to oversee the evacuation. They will also be on
hand to help you with your fire safety duties, such
as performing visual checks of equipment and lead
ing fire drills to test the effectiveness of your pro
cedures, and to help familiarise staff with the plan.
Lastly, inform all staff on how to use the fire
extinguishing equipment in your surgery.

Review
A risk assessment is never finished, and you should
constantly monitor what you are doing to see how
effectively the risks are being controlled. It also needs
updating should there be a change in building layout
or the activities that are carried out. Acquiring a new
piece of equipment may seem like just a small change,
but together, a few small changes can have a signifi
cant effect. That is why many fire services recom
mend reviewing the assessment at least once a year
so you know it is up to date. The ultimate responsibil
ity for complying with special fire safety regulations
falls to the owner of the dental practice. He or she can
either carry out the fire risk assessment himself or
herself or ask a competent individual to assist. Many
business owners choose to hire professional risk
assessors to complete it on their behalf. This not only
saves them time and effort, but also gives them
the peace of mind that it has been done correctly and
that no risks have been overlooked._

written an open letter calling on Americans to turn
their backs on the Trump presidency. In response
to Trump’s reaction to the tragic events in Charlottesville, Virginia, on 12 and 13 August, the fullpage letter in USA TODAY has caused the already
maxed-out political turmoil to spill over into the
dental industry.
In his opening sentence, Fischer wrote: “As the
founder and CEO of Ultradent Products, Inc., a
proud American manufacturer that employs over
1,400 Americans and exports 65 % of what we
manufacture, I feel it is my duty and obligation
to make my voice heard.” Pointing to Ultradent’s
core company values of “integrity, quality, care,
innovation and hard work” as guiding his leadership of the company, Fischer felt compelled to
voice his disapproval at what he describes as an
“out of control” Trump, going as far to say “should
I ever find myself in the presence of Donald Trump,
I will literally turn my back to him.” This call to action from Fisher has not been met with open arms
from all corners of dentistry. Some loyal Trump
supporters working in the industry suggested via
Facebook that Americans and dentists turn their
backs on Ultradent Products.
In the letter, now published on turnyourbacks.org,
Fischer concludes by writing: “For those of you
who support this person or who don’t feel comfortable that it is correct to ‘turn your back,’ you
too are my fellow Americans, and I equally defend
your right to freedom of speech. Do as your conscience dictates.”

According to a recent study released by the Canadian Medical Association, artificial sweeteners may
not be as healthy alternative as first thought.
In a systematic review of 37 studies that followed
over 400,000 people for an average of 10 years,
the researchers aimed to find out about negative
long-term effects on weight gain and heart disease in people who consumed artificial sweeteners. Initial results did not show a consistent
effect on weight loss, while the longer observational studies showed a link between the consumption of artificial sweeteners and relatively

artificial sweeteners are fully characterised.”

First generation graduates

LA&HA Master’s Programme
This year, the first generation graduated the
LA&HA Master’s Programme in Laser Dentistry.
The programme is an educational curriculum
designed by the Laser and Health Academy to
provide participants with a comprehensive level
of knowledge about laser use in dentistry, with
an overview of laser applications, laser physics,
safety and hands-on practical work.
This year's graduating class has eight laser enthusiasts from six different countries. Some of the
students were new to lasers, while others had already been working with lasers for several years.

A total of five separate modules are required for
completion of the programme, giving participants
the skills needed for using a laser system in the
dental office.
There is strong interest from dental experts
worldwide for the LA&HA Master’s Programme,
knowing that an in-depth knowledge of laser use
is essential for running a successful dental practice. The next modules are in full swing. For dates

Fossilised teeth cast doubt over

Prevention before intervention in the

Humans’ arrival in South East Asia

Oral care of older patients

South East Asia is a key region for understanding the human dispersal out
of Africa and down to Australia. According to recent fossil teeth findings by
researchers from the University of Queensland in Brisbane and Macquarie
University in Sydney, this migration towards Australia may have occurred
20,000 years earlier than previously thought. In a video posted online, the
scientists follow the footsteps of Eugène Dubois, the paleoanthropologist
famous for his discovery of “Java Man” (Homo erectus). In the Sumatran
region of Indonesia, they reenter a cave site called Lida Ajer, where in the
late 1800s the Dutchman collected fossil teeth from other hominins.
According to Dr Gilbert Price of the University of Queensland’s School of Earth
and Environmental Sciences, Dubois’s recovery of the human teeth
was in itself very interesting, but no
one had spent much time trying to
determine its significance. However,
after an in-depth documentation
of the cave and reanalysis of the
specimens using a new dating programme, it was confirmed that the
teeth came from modern humans,
Homo sapiens, and most interestingly that they dated to as long as
73,000 years ago.
In a twist that may become a contentious topic at a later date, the
findings from the study also suggest humans could have potentially
made the crossing to Australia even
earlier than the accepted 60,000 to

65,000 years ago.

In light of the ageing population, dentists need to be aware of the risks of
multifactorial oral health problems in elderly patients. A recent article has
recommended a maximum interception approach involving all members of
the healthcare team and promoting evidence-based self-care.
Dental professionals must be prepared for the sheer number of older patients, especially among the baby boomers (the generation born between
1946 and 1964), retaining their natural teeth for longer, stated article author Prof. Laurence J. Walsh, University of Queensland, Australia. Particular
problems include root surface caries in patients with a strong history of coronal caries and those who suddenly develop salivary hypofunction. Furthermore, elderly patients suffer from more chronic diseases and are medically
more complex.
Older patients sometimes cannot maintain sufficient oral health, owing to a
decline of fine motor skills and reduced sight. Hence, Walsh advised a multidisciplinary approach with doctors, nurses and carers working together to
provide good oral health for patients living in long-term care facilities. A key
message must promote oral health as part of overall health, he said.

Laserlicht im
Land der Sonne

Dr. Dimitris Strakas

Liebe Kolleginnen und Kollegen,
die Laserzahnheilkunde hat ihre Kinderjahre längst hinter sich gelassen, und heute leben wir in einer Zeit,
in der der Laser – neben anderen technischen Innovationen und digitaler Technologien – ein fester Bestandteil moderner Zahnmedizin ist. Die wohl größte und älteste wissenschaftliche Gesellschaft ist dabei
die World Federation for Laser Dentistry (WFLD). Bereits seit 1988 verbindet und betreut sie Zahnärzte auf
dem Gebiet der Laserzahnheilkunde. Im Herzen dieser Familie steht die Europäische Division (ED), die über
alle Jahre hinweg eine bedeutende Rolle gespielt hat. Nun findet der bereits 6. WFLD-ED Kongress statt, welcher in diesem Jahr in der wunderschönen Stadt Thessaloniki im Land der Sonne, in Griechenland, zu Gast ist.
Wir sind mehr als erfreut über die Feststellung, dass anlässlich dieses wichtigen wissenschaftlichen
Ereignisses alle Kräfte aus der Laserzahnheilkunde mitwirken. Damit wird einmal mehr die Tatsache unterstrichen, wie bestrebt Zahnärzte aus aller Welt sind, an aktuellen Forschungen und klinischen Projekten
der prominentesten Meinungsführer auf diesem Gebiet teilzuhaben und diese kennenzulernen. Darüber
hinaus fühle ich mich sehr geehrt, dass zum allerersten Mal sämtliche „Haupt“-Unternehmen innerhalb
der Laserzahnmedizin und Restaurativen Zahnheilkunde als Sponsor auf diesem Event vertreten sind. Ihre
Teilnahme an der Kongressausstellung gibt uns die Gelegenheit, eine vielfarbige Palette an Wellenlängen
und Lasergeräten zu erleben.
23 Sponsoren, 25 geladene Referenten, 70 mündliche Präsentationen, 30 E-Poster, ein paralleler Ästhetik- und CAD/CAM-Kongress am Samstag und acht kostenfreie Workshops stellen ein erfolgreiches und
informatives Treffen sicher. Auch für das soziale Miteinander gibt es genug Raum: Beim Welcome Cocktail
in der Ausstellung und dem Gala Dinner gibt es viele Möglichkeiten, Kollegen aus der ganzen Welt kennenzulernen und sich mit ihnen auszutauschen.
Am 22. und 23. September 2017 öffnet der 6. WFLD-ED Kongress seine Türen im Hotel Makedonia Palace
in Thessaloniki und lädt Sie herzlich dazu ein, an diesen zwei Tagen in die farbenreiche Welt der zahnärzt
lichen Laser-Familie einzutauchen.
Herzliche Grüße

Dr. Dimitris Strakas
Vorsitzender der WFLD-ED

26. DGL
Workshop-Kongress
Autorin: Dr. Ute Gleiss

Dem vielfachen Wunsch entsprechend, doch wieder einmal einen Kongress in Aachen besuchen zu
können, fand der diesjährige Workshop-Kongress
der Deutschen Gesellschaft für Laserzahnheilkunde
(DGL e.V.) am 23. Juni 2017 im Universitätsklinikum
Aachen statt.
Prof. Dr. Norbert Gutknecht eröffnete den Kongress mit einer Erläuterung der innovativen Idee zum
Workshop. Kontrastierend zum klassischen Kongresskonzept stand hier der anwendungsspezifische, benutzerfreundliche Aspekt im Vordergrund.
Am Vormittag sollte zunächst die Vorstellung der
theoretischen Grundlagen spezieller Lasersysteme
erfolgen, für den Nachmittag waren dann praktische Übungen und Demonstrationen an den entsprechenden Lasersystemen mit den jeweiligen Referenten geplant.
Abb. 1: Dr. Stefan Grümer sprach
über die vielfältigen Einsatzgebiete
des 810 nm-Diodenlasers.

Darüber hinaus berichtete Prof. Gutknecht über
die erfolgreiche Re-Evaluierung und Re-Akkreditie-

rung des Masterstudienganges „Lasers in Dentistry“
an der RWTH Aachen, die tags zuvor stattgefunden
hatte, parallel zur Kongressvorbereitung. Herausgestellt wurde weiterhin die Einbindung der DGL in
die D
GZMK (Deutsche Gesellschaft für Zahn-, Mundund Kieferheilkunde) mit einer eigenen Sektion und
einem eigenen Kongress. In diesem Zusammenhang verwies der Präsident auch noch einmal auf die
durchaus sehr erfolgreiche Präsentation der Gesellschaft im Rahmen des Frankfurter Zahnärztetages
im Herbst 2016.

Theoretische Grundlagen
Nach der Eröffnungsrede begann der Kongress
mit den Vorstellungen der theoretischen Grundlagen. Hierzu referierte zunächst Dr. Johannes-Simon
Wenzler über die klinisch relevanten Indikationen für
den Einsatz des 445, 660 und 970 nm-Diodenlasers.
Am Nachmittag konnten sich die Teilnehmer dann in
einem Hands-on-Kurs selbst an dem SiroLaser der
Firma Dentsply Sirona versuchen. Besonders inte
ressant erschienen hier auch die guten Studien
ergebnisse der 445 nm-Wellenlänge im endodon
tischen Bereich.
Dr. Detlef Klotz referierte im Anschluss über den
Einsatz des 2.940 nm-Erbium:YAG-Lasers. Er verstand es, dass ungemein breite Einsatzspektrum des
Er:YAG-Lasers umfassend darzustellen. Am Nach
mittag führte er einen vielbeachteten praktischen Teil
an einem Er:YAG-Laser der Firma Morita durch.
Dr. Gabriele Schindler-Hultzsch erarbeitete die
klinisch relevanten Indikationen für den Einsatz des
940 nm-Diodenlasers und des 2.790 nm-Erbium,
Chromium:YSGG-Lasers. Es imponierten hier die
vielfältigen Einsatzmöglichkeiten sowie ihr spe
zielles Vorgehen im Bereich der Kinderzahnheilkunde. Am Nachmittag erfolgte eine intensive
Vertiefung der Thematik sowie entsprechende
Übungen an den Lasern WaterLase iPlus und EPIC
der Firma Biolase.

In seinem gewohnt kurzweiligen und mitreißenden
Vortragsstil sprach Dr. Stefan Grümer als letzter
Redner des Vormittags über die vielfältigen Einsatzgebiete des 810 nm-Diodenlasers. Er erarbeitete hier
nicht nur sehr übersichtlich alle Grundlagen, sondern
konnte durch seinen reichhaltigen Erfahrungsschatz
auch eine vielfältige Auswahl an Falldokumentatio
nen präsentieren und nahm darüber hinaus Bezug
auf die neu auf dem Markt befindlichen Geräte, wie
z. B. den SOLASE.

Neuer DGL-Vorstand
Eingebunden in diesen Workshop-Kongress war
auch die DGL-Mitgliederversammlung mit den anstehenden Vorstandswahlen. Nachdem die Vorstandsmitglieder ihre Berichte abgegeben und ihre Ämter
niedergelegt hatten, wurde unter der Leitung des
zeitlichen Vorsitzenden Dr. Kampf die Vorstandswahl durchgeführt. DGL-Geschäftsstellenleiterin
Frau Speck fungierte als Wahlhelferin.
Der neue Vorstand setzt sich nach der Wahl nun wie
folgt zusammen:
Präsident: Prof. Dr. Norbert Gutknecht
Vizepräsident: Dr. Detlef Klotz
Generalsekretär: Prof. Dr. Dr. Siegfried Jänicke
Schatzmeiser: Dr. Stefan Grümer
Vertreter Praktikerbeirat: Dr. Thorsten Kleinert
Vertreter wissenschaftlicher Beirat:
Prof. Dr. Andreas Braun
Freies Vorstandsmitglied:
Prof. Dr. Anton Sculean, Dr. Gabi Schindler-Hultzsch

Workshops
Nach der Mittagspause wurden drei Gruppen
gebildet, um an den praktischen Workshops teilnehmen zu können. Die Gruppen rotierten im Stundenrhythmus, sodass jeder Teilnehmer an jeder Demons

Abb. 3

tration und Übung teilnehmen konnte. Trotz
vorangeschrittener Stunde war der Vortragsraum
auch in den Abendstunden des Kongresstages bis
auf den letzten Platz – und darüber hinaus – gefüllt.
Dr. Rene Franzen berichtete über die Neuerungen
im Bereich Lasersicherheit. Er referierte zielorientiert
und kurzweilig über die neuen Vorgaben und gab den
Teilnehmern anschließend alle relevanten Dokumente
zum Herunterladen direkt mit auf den Weg. In seiner
einzigartigen Vortragsweise verstand er es, ein trockenes Thema witzig und praxisorientiert aufzubereiten.

Zum Abschluss des Kongresses referierte Dr. Detlef
Klotz über die Neuerungen in der Abrechnung. Auch
dieser Vortrag fand sehr reges Interesse, auch wenn
sich aufgrund der fortgeschrittenen Stunde und
der Begrenztheit der Vortragszeit nicht alle Details
vollumfänglich abarbeiten ließen.
Insgesamt ist das Konzept der Verknüpfung von
Theorie und Praxis bei den Teilnehmern sehr gut angekommen. Dank der ständigen Präsenz der Referenten und Firmen sowie einer freundschaftlichen
und kollegialen Atmosphäre konnten mehr als einmal
Fragestellungen direkt beantwortet und eine Vielzahl neuer Ideen und Anregungen mit auf den Weg
gegeben werden. Der Wunsch nach einer Wieder
holung eines Kongresses in dieser Form wurde vielfach geäußert._

Laserschutz für
Zahnmediziner
Autoren: Jiaoshou (Prof.) Dr. Frank Liebaug, Dr. Ning Wu

In den letzten 50 Jahren hat die Entwicklung
von Dentallasersystemen dem niedergelassenen
Zahnarzt für Therapie und Diagnostik erhebliche
Fortschritte beschert. Die Einsatzmöglichkeiten
sind nicht mehr nur auf die Weichgewebechirurgie
begrenzt, sondern umfassen auch Hartgewebe
bearbeitung, Kariesdetektion und -monitoring sowie
Parodontitis- und Periimplantitistherapie.
Minimalinvasive Behandlungstechniken sind durch
die derzeit in Deutschland erhältlichen Lasersys
teme erst möglich geworden. Durch sachkundigen
Einsatz von lasergeeigneten Wellenlängen können
Behandlungsergebnisse in der Zahnmedizin opti
miert und die Patientenzufriedenheit erhöht wer
den. Für den Einsatz des Lasers durch den Zahnarzt
wird in § 2(2) Medizinprodukte-Betreiberverord
nung der Nachweis der entsprechenden Fachkunde
beim Betreiben eines Lasergerätes (aktives Medizin
produkt) verlangt.
Zum Betrieb von Lasergeräten in den Behand
lungsräumen ist laut Unfallverhütungsvorschrift
BGV B2 „Laserstrahlung“ (vormals VBG 93) bzw.
OStrV die Bestellung eines Laserschutzbeauftragten
nötig. Seit dem 30.11.2016 ist die neue, aktualisierte
OStrV in Kraft!

Der „neue“ Laserschutzbeauftragte
Die OStrV „Verordnung zum Schutz der Beschäf
tigten vor Gefährdungen durch künstliche optische
Strahlung (Arbeitsschutzverordnung zu künstlicher
optischer Strahlung – OStrV)“ stellt die gesetz
liche Grundlage für den Laserschutz in Kliniken und
Zahnarztpraxen dar. Diese Richtlinie wurde bereits am
27. Juli 2010 mit der „Verordnung zum Schutz der Be
schäftigten vor Gefährdungen durch künstliche opti
sche Strahlung (OStrV)“ durch die Bundesregierung in
deutsches Recht umgesetzt. Sie umfasst sowohl die
direkten Gefährdungen der Beschäftigten als Folge
direkter Einwirkung der am Arbeitsplatz durch den
Arbeitsprozess auftretenden, künstlichen optischen
Strahlung (Gefährdungen von Augen und Haut) als
auch die sich dabei ergebenden indirekten Gefähr
dungen. Indirekte Gefährdungen können zum Beispiel
als Folge von Reflektionen (Blendwirkung) oder durch
Strahlung entstandener Gase, Dämpfe, Stäube, Nebel
und explosionsfähiger Gemische auftreten.
Wesentliches Merkmal dieser Verordnung ist in § 5
die Einführung sogenannter „Fachkundiger Perso
nen“, die die notwendigen Gefährdungsbeurteilun
gen erstellen sollen. Außerdem sind Laserschutz
beauftragte schriftlich zu bestellen.

[43] =>

Fortbildung

§ 5 OStrV – Fachkundige Personen,
Laserschutzbeauftragter
(1) Der Arbeitgeber hat sicherzustellen, dass die
Gefährdungsbeurteilung, die Messungen und die
Berechnungen nur von fachkundigen Personen
durchgeführt werden. Verfügt der Arbeitgeber
nicht selbst über die entsprechenden Kenntnisse,
hat er sich fachkundig beraten zu lassen.
(2) Vor der Aufnahme des Betriebs von Lasereinrich
tungen der Klassen 3R, 3B und 4 hat der Arbeitge
ber, sofern er nicht selbst über die erforderlichen
Fachkenntnisse verfügt, einen Laserschutzbeauf
tragten schriftlich zu bestellen. […] Die fachliche
Qualifikation ist durch die erfolgreiche Teilnahme
an einem Lehrgang nachzuweisen […]. Der Laser
schutzbeauftragte hat folgende Aufgaben:
1. die Unterstützung des Arbeitgebers […] bei
der Durchführung der notwendigen Schutzmaß
nahmen nach § 7;
2. die Gewährleistung des sicheren Betriebs von
Lasern nach Satz 1.
Bei der Wahrnehmung seiner Aufgaben arbeitet
der Laserschutzbeauftragte in größeren Einrich
tungen mit der Fachkraft für Arbeitssicherheit und
dem Betriebsarzt zusammen. Die wesentlichen Än
derungen für die Aufgaben des Laserschutzbeauf
tragten sind wie folgt:
– Die Laserschutzbeauftragten sind nun per Ver
ordnung verpflichtet, an der Erstellung der Ge
fährdungsbeurteilung mitzuwirken. Hierfür sind
umfangreiche Kenntnisse erforderlich.
– Die Laserschutzbeauftragten haben ab sofort die
Sicherheit der Lasereinrichtung zu gewährleisten.
Dies bedeutet mehr Verantwortung als früher.
– Die Laserschutzbeauftragten müssen sich regel
mäßig weiterbilden.
– Laserschutzbeauftragte, die bis dato nur nach der
DGUV Vorschrift 11 (BGV B2) ausgebildet wur
den, müssen ebenfalls an einem Auffrischungs
kurs teilnehmen.
– Die Begrifflichkeit der „Sachkunde“ wurde in
„Fachkenntnisse“ geändert.

Zu wenig Schlaf sorgt für

Abschluss in Zahnmedizin verspricht

Erhöhte
Risikobereitschaft

Das höchste Einstiegsgehalt

© pathdoc/Shutterstock.com

Die Onlinejobbörse StepStone veröffentlichte
kürzlich einen aktuellen Gehaltsreport für Absol
venten – mit guten Aussichten für Medizin und
Zahnmedizinstudenten.
Den präsentierten Zahlen liegen Befragungen
im Zeitraum 2014 bis 2016 unter 150.000 Fach
und Führungskräften zugrunde. Berücksichtigt
wurden die Daten von Absolventen bzw. Berufs
einsteigern mit akademischer Ausbildung und
maximal zwei Jahren Berufserfahrung.
Am höchsten sind demnach die Einstiegsgehäl
ter in den Regionen BadenWürttemberg, Bayern
und Hessen. Zwischen 45.000 und 46.999 Euro
Bruttojahresgehalt wandern hier in die Lohn
tüte der Absolventen. Wer mit einem Topgehalt
ins Berufsleben einsteigen will, ist mit einem

Abschluss in Medizin oder Zahnmedizin auf
dem ersten Rang in puncto Einstiegsgehalt
(50.170 Euro) ganz vorne dabei – Kopf an Kopf mit
den Absolventen in Wirtschaftsingenieur wesen
(48.238 Euro) und Naturwissenschaften (Bio
logie, Chemie, Pharmazie, Physik; 48.071 Euro).

Zahnärzte bewerten ihre

Wirtschaftliche Lage optimistisch
Junge Erwachsene haben ein natürliches Schlaf
bedürfnis von durchschnittlich rund 9 Stunden
pro Tag, bei älteren Erwachsenen sind es um
die 7,5 Stunden. Schlafen aber beispielweise
junge Erwachsene weniger als 8 Stunden pro
Nacht, führt dies vermehrt zu Aufmerksam
keitsdefiziten.
Forschende der Universität Zürich und des Uni
versitätsspitals Zürich haben nun eine weitere
kritische Konsequenz von chronischem Schlaf
mangel identifiziert: eine erhöhte Risikobereit
schaft. Die Wissenschaftler untersuchten das
Risikoverhalten von 14 gesunden männlichen
Studenten im Alter von 18 bis 28 Jahren. Wäh
rend eine einzelne Nacht ohne Schlaf keinen Ein
fluss auf die Risikobereitschaft hatte, verhielten
sich 11 von 14 Studienteilnehmern während einer
Woche mit reduzierter Schlafdauer (5 Stunden
pro Nacht) signifikant risikoreicher. Bedenklich ist
insbesondere ein weiterer Befund: Die Studenten
schätzten ihr Risikoverhalten gleich ein wie unter
regulären Schlafbedingungen.
Die Forschenden weisen zudem erstmals nach,
dass eine niedrige Schlaftiefe im rechten präfron
talen Kortex direkt mit vermehrtem Risikoverhalten
zusammenhängt.

im Vergleich zum üblicherweise niedrigeren

Prozentpunkt zulegen. In den Vorjahren lagen
die Steigerungsraten zwischen 5,3 und 9,8

nen Fachgruppen, zeigt sich ein uneinheitliches
Bild: So beurteilen Hausärzte und Zahnärzte
ihre aktuelle wirtschaftliche Lage sowie die
Aussichten für die kommenden sechs Monate
klar optimistisch (+6,3/+5,6). Auch der Index
der Fachärzte liegt zwar noch immer im nega
tiven Bereich, sank jedoch von –11,2 auf –7,2.
Dagegen verschlechterte sich der Wert bei den
Psychologischen Psychotherapeuten abermals
und erreichte mit –18,9 seinen niedrigsten
Stand seit Beginn der Erhebung.

Antikorruptionsgesetz sorgt weiterhin für

Verunsicherung innerhalb der
Zahnärzteschaft
Am 4. Juni 2016 trat das Gesetz zur Bekämpfung von Korruption
im Gesundheitswesen, kurz Antikorruptionsgesetz, in Kraft. Zwar
haben Verbände und Kammern ihre Mitglieder seinerzeit ausrei
chend über die neue Gesetzgebung informiert, dennoch, so scheint
es, ist die Verunsicherung innerhalb der Branche nach wie vor groß.
Grund: Zwar waren jegliche Handlungen, die der Vorteilsnahme
und Vorteilsgewährung dienten, schon seit jeher verboten, unter
Strafe jedoch stehen sie erst seit einem Jahr. Für Zahnärzte und
Zahntechniker bedeutet das, dass Verstöße, ob wissentlich oder un
wissentlich, eine andere Qualität erfahren. Es gilt die alte Weisheit:
Unwissenheit schützt vor Strafe nicht. Entsprechend groß sind die
Befürchtungen, schuldlos, beziehungsweise unbeabsichtigt, gegen
das Gesetz zu verstoßen.

© r.classen/Shutterstock.com

Dies bestätigt auch Werner Vogl, Fachanwalt für Medizinrecht. Vogl
hält Vorträge zum Antikorruptionsgesetz auf Fachmessen wie der „id
infotage dental“ am 14. Oktober in München. Er kennt die Fragen von
Zahnmedizinern und technikern nur allzu gut. „Die Branche ist auf
geschreckt“, so der Göppinger Fachanwalt. „Vor allem bezüglich der
Zusammenarbeit zwischen Zahnärzten und Dentallaboren herrschen
viele Unklarheiten, ebenso im Bereich der Anbahnung von Koopera
tionen zwischen Laboren und Zahnarztpraxen.“
Zahnärzte und Zahntechniker, die sich umfangreich bei Werner Vogl
über das Antikorruptionsgesetz informieren möchten, haben dazu am
14. Oktober auf der Fachmesse „id infotage dental“ die Gelegenheit.
Um 12 und um 14 Uhr referiert Vogl in der „dental arena“ und beant
wortet alle wichtigen Fragen zum Thema.

Arztbewertungsportale sind das wichtigste Bin
deglied zwischen Arzt und Patient, da sie ihnen
helfen, zueinanderzufinden. Das ist das zentrale
Ergebnis einer Umfrage von jameda, Deutsch
lands größtem Arztbewertungsportal. Demnach
suchen 65 Prozent der Patienten auf Arztbewer
tungsportalen nach dem passenden Arzt. Damit
sind diese noch vor dem Rat von Freunden und
Familie (61 %) die wichtigste Quelle zur Arztsu
che. Nach den Freunden und der Familie (67 %)
stellen die Portale darüber hinaus auch eine ver
trauenswürdige Quelle in Arztfragen dar: Jeder
Zweite vertraut der Meinung anderer Patienten
auf Arztbewertungsportalen. Besonders schät
zen Patienten die leichte Auffindbarkeit relevan
ter Informationen (66 %) und die damit verbun
dene Möglichkeit, den passenden Arzt zu finden
(64 %).
Ärzte nutzen Arztbewertungsportale für ihr Pra
xismarketing und als Feedback-Kanal. Bewer
tungsportale helfen Ärzten dabei, Patienten auf
ihre Praxis aufmerksam zu machen: Rund zwei
Drittel der Ärzte schätzen an Arztbewertungs
portalen die erhöhte Sichtbarkeit ihrer Praxis im
Internet, die Hälfte die Möglichkeit der Patienten
akquise sowie das Patienten-Feedback. Zudem
sind fast alle Ärzte (92 %) der Meinung, dass
Patientenbewertungen zur Verbesserung der me
dizinischen Leistung in der Praxis beitragen. Zwei
Dritteln hilft das Feedback auf Arztbewertungs
portalen dabei, die Bedürfnisse ihrer Patienten
besser zu verstehen und darauf einzugehen.

Diodenlaser in der Zahnmedizin stellen eine her
vorragende Ergänzung für den zahnärztlichen
Alltag dar. Wichtig ist dabei eine intuitive und
einfache Bedienung. Das Unternehmen BluLase
bietet hier eine Kombination von Diodenlaser und
Photosensitizer an, welche den schnellen und un
komplizierten Einstieg erlaubt.
Die antibakterielle photodynamische Therapie
ist ein etabliertes Verfahren zur Behandlung ver
schiedener Krankheitsbilder. Das Grundprinzip
der aPDT: Laserlicht einer festgelegten Wel
lenlänge aktiviert einen spezifischen Farbstoff,
genannt Photosensitizer, mit maximaler Absorp
tion im Bereich dieser Laserwellenlänge, und
regt damit die Bildung von reaktivem Sauerstoff
(ROS, reactive oxygen species) an. Im Rahmen
des „therapeutischen Fensters“ erfolgt dann die
antibakterielle Wirkung auf den entzündungsaus
lösenden, anaeroben subgingivalen Biofilm.
ROS schädigen die Bakterienzellen durch Oxida
tion lebenswichtiger Zellbestandteile und führen
damit unmittelbar zur Nekrose und Apoptose

der behandelten Krankheitserreger. Der Zelltod
erfolgt durch „oxidativen Stress“ in wenigen
Sekundenbruchteilen und weitaus schonender
als mit der konventionellen Antibiotikatherapie.
Auch aus diesem Grund stößt die Anwendung
der aPDT bei der Behandlung von infektiösen Er
krankungen auf breites Interesse. Zudem ist die
aPDT (bis 500 mW) nach aktueller Gesetzeslage
an q ualifizierte Mitarbeiter delegierbar.

Einfühlsame Ärzte sind

Die besseren Ärzte
Fühlen sich Patienten verstanden, haben sie we
niger Schmerzen, sind zufriedener und nehmen
Medikamente zuverlässiger ein. Dabei werden
Ärzte vor allem dann als einfühlend wahrgenom
men, wenn sie Verständnis äußern und bei ihren
Empfehlungen die Patientenbedürfnisse berück
sichtigen. Dies ist das Ergebnis einer wissen
schaftlichen Analyse von Patientenbewertungen
aus 64 Studien. Je länger das Gespräch zwischen

Arzt und Patient geht, desto wohler fühlen sich
Patienten. Stress durch bürokratische Arbeiten
und langjährige berufliche Praxis verringern je
doch das Einfühlungsvermögen einiger Ärzte.
Ärzte in Australien, den USA und Großbritannien
werden zudem am empathischsten bewertet.
Deutschland liegt im Mittelfeld.
