Transmission of SARS-CoV-2 in dental
offices very unlikely, study says

DENTAL TRIBUNE

COLUMBUS, Ohio, U.S.: Researchers

worldwide investigate COVID-19, and
every week, new information about
the illness is discovered or confirmed.
A recent study from the Ohio State
University has shown yet again that
a SARS-CoV-2 infection risk at the
dentist’s office is low, despite the tenacious misconception that patients
and treatment providers are at high
risk of catching COVID-19 at the dentist’s office.
Dental procedures are known to
produce a considerable amount of
aerosol, and this leads to fears that saliva in the aerosols generated during
dental treatments could make the
dentist’s chair a high-transmission
location since SARS-CoV-2 spreads

mainly through respiratory droplets.
In order to investigate whether saliva
is the main source of the spray, the
researchers collected samples from
personnel, equipment and other
surfaces reached by aerosols during a
range of dental procedures.

“Getting your teeth cleaned does not
increase your risk for COVID-19 infection any more than drinking a glass
of water from the dentist’s office
does,” said lead author Dr. Purnima
Kumar, professor of periodontics at
Ohio State. “These findings should
help us open up our practices, make
ourselves feel safe about our environment and, for patients, get their oral
and dental problems treated—there
is so much evidence emerging that
if you have poor oral health, you are
more susceptible to COVID,” Kumar
added.

The World’s Dental Newspaper Middle East & Africa Edition
By analysing the genetic makeup of
the organisms detected in those samples, the researchers determined that
dental irrigant, not saliva, was the
main source of any bacteria or viruses present in the spatter and spurts
from patients’ mouths. Even when
low levels of SARS-CoV-2 were detected in the saliva of asymptomatic
patients, the aerosols generated during their procedures showed no signs
of SARS-CoV-2.

The study, titled “Sources of SARSCoV-2 and other microorganisms in
dental aerosols,” was published online on May 12, 2021, in the Journal of
Dental Research, ahead of inclusion in
an issue.

How PIEZOSURGERY has
redefined bone surgery
20 years of PIEZOSURGERY technology
By mectron s.p.a.
Twenty years ago, the International
Dental Show (IDS) saw the premier of
the PIEZOSURGERY unit, a first for piezoelectric bone surgery. Since then,
mectron has not only succeeded in
revolutionising clinical reality with
PIEZOSURGERY, but also benefitted
practioners and patients worldwide
with two decades of ease of use and
minimal invasiveness.

"When I started developing piezoelectric bone surgery more than 20
years ago, I never expected that Piezosurgery would redefine all bone
surgery," says Prof. Tomaso Vercellotti, the inventor of PIEZOSURGERY,
today, 20 years after the first system
was launched.
Yet the success story of the original
PIEZOSURGERY method was already
underway in 1997, when the peri-

odontist Vercellotti, in partnership
with the company mectron, began
working on the idea of ultrasonic
bone surgery. Even then it was clear
to them: an essential success factor
for oral surgical treatment is reducing its invasiveness to a minimum,
ensuring that the surrounding soft
tissue is spared, therefore enabling
rapid healing. Vercellotti and mectron saw a solution for this in the
use of modulated ultrasonic vibra-

→ THE EVOLUTION OF PROPHYLAXIS
COMBI touch
AIR-POLISHING AND ULTRASOUND IN ONE UNIT
→ easy switch from supra to subgingival air-polishing by a simple click
→ subgingival perio air-polishing tip – flexible, soft
and anatomically adjustable to the periodontal pocket
→ more than 40 inserts for scaling, perio, endo and prosthetics
→ SOFT MODE: the ultra-gentle scaling for sensitive patients

tions. Shortly afterwards, mectron
succeeded in building the first prototype and carrying out the first extraction treatments.

PIEZOSURGERY: A new paradigm in bone surgery
In 2001 the time had come: The
world's first PIEZOSURGERY device
was presented at IDS. In 2005, the
first implant bed preparation using
PIEZOSURGERY was successfully
completed. Vercellotti: "2005 was
also the year in which a grand master of periodontology from Harvard
University defined PIEZOSURGERY
as a new paradigm. Making us very
happy, of course." And indeed, piezoelectric bone surgery became a clinical reality worldwide over the following years. This success is based not
only on the exceptional intraoperative control PIEZOSURGERY offers its
users, but also the reduction in the
surgical trauma to the surrounding
tissue, enabling faster healing than
after more invasive cutting surgical
procedures.
In 2011, the 4th generation of PIEZOSURGERY equipment was launched.

include in 2015, when the world's
narrowest osteotomy instrument,
OT12S, was introduced. With a width
of only 0.25 mm, it is suitable for all
osteotomy techniques where standard bone saws have access difficulties. In 2019, the REX PiezoImplant
was launched on the market as the
first implant with a minimally invasive implant bed prepared exclusively with PIEZOSURGERY. The innovative REX PiezoImplant wedge
implants are suitable for use in the
narrow ridge of the jawbone. This is
because their unusual shape means
that the bone does not have to be
augmented before the implant is
placed.

30,000 customers in over 80
countries have already been
won over
Today, more than 250 scientific and
clinical studies have proven the positive effects of using the PIEZOSURGERY method. The more than 90
different instruments for the PIEZOSURGERY equipment are exclusively
produced in Italy and distributed
worldwide in more than 80 countries. More than 30,000 customers
have so far been convinced of the
advantages of piezoelectric bone surgery. Vercellotti: "The commitment
of all those involved in improving PIEZOSURGERY year on year has been
rewarded with the confidence of an
extraordinary number of surgeons
and, above all, with the satisfaction
of the patients treated."

Interview: “Attempting to make my own
shield seemed like a productive use of time”
By Iveta Ramonaite, Dental Tribune
International

The face shield we see now required 58 prototypes. What did
you learn in the process, and when
did you know that the product was
ready to be sold on the market?

The pandemic has caused professional and private challenges. However, some people managed to use
this downtime to stimulate their
creativity and to test their entrepreneurial skills. One of these people is
Dr. Scott Yamaoka, who devoted his
time and energy to creating a face
shield that would protect his dental
team and patients from SARS-CoV-2
infection in the workplace. In this interview, he and his son, Zach Yamaoka, tell Dental Tribune International
how they turned their idea into a
product—the next generation optical face shield that allows dentists
to comfortably fit magnification
loupes with fiber optic lighting.

© Scott Yamaoka

First of all, congratulations on your
invention! Could you start by telling our readers a bit about your
creation and what led you to developing it at home in your garage,
during the pandemic?

Zach Yamaoka: The story of the
Loupe Shield engineering is the story of three discoveries made while
making 58 prototypes.

Vancouver-based periodontist Dr. Scott Yamaoka (left) and his son Zach Yamaoka, design engineer at Dyson.

Dr. Scott Yamaoka: As the pandemic
set in and dental offices shut down, I
began thinking about how we could
get back to work safely. It became
clear that, moving forward, face
shields would be necessary to protect our dental team and patients.
Images of hospital workers helping
COVID-19 patients were circulating
in the news, and that really drove
this message home.

ware store. But even those had sold
out, and again, would not accommodate magnification and lighting.

At the outset of the pandemic, it
was nearly impossible to get one of
these shields, which were sold out
everywhere. And even if you could
somehow get one, I realized that
the shields that were made of foam
and plastic film and used by hospital
workers would be ineffective in the
dental environment, in which dental professionals require clarity, the
accommodation of magnification
loupes and fiber optic lighting. The
only other options available were
construction shields from the hard-

It is not easy to create a face shield
that not only is pleasing to the
eye but also has a protective function. Could you take our readers
through the creation process and
talk about some of the materials
you used?

Attempting to make my own shield
seemed like a productive use of time
and mental energy during the shutdown and gave me solace in that
I could control a small part of my
destiny and the outcome of the pandemic.

Dr. Scott Yamaoka: Creating the prototype was a matter of searching for
available products that I could use
to construct the basic components
of the face shield: a head harness, a
plastic attachment system and the
plastic itself.

While looking at industrial shields
for welding and researching the construction industry, I had the idea to
use a safety construction helmet. We
had one at home. The benefits of the
secure head harness provided the
foundation, and the brim allowed
space for optics and lights. Removing the top part of the helmet with a
Dremel reduced the weight and also
allowed the plastic material to adapt
to the rim of the brim to secure the
magnets.
Using magnets meant that dentists
could efficiently change the sheets of
visor plastic in between patient visits
and replace them when they became
damaged or scratched. Seeing magnets on our fridge for holding paper
notes gave me the idea that they
could be used to secure the plastic,
provided they were strong enough
to hold it. We have used rare-earth
magnets to surgically move teeth,
and similar products were available
at the hardware store.

Visor plastic was not available anywhere at the time, so I thought that
we could use acetate plastic from
the overhead projectors we once
used when I was in grade school.
Fortunately, they were still on sale,
but their clarity was not ideal. The
plastic we are using now is imported
from the U.K. and incorporates the
latest advances in clarity, including
proprietary nanosurface technology.
One of the comments we receive the
most is that people forget that they
are wearing the shield!
Zach Yamaoka: As the shield developed, we incorporated more Aesthetic aspects. However, the function
of the face shield has always been
important, since things are only
beautiful if they work. The thinness
of the rim on the final product is the
result of a desire to reduce weight.
The square shape reduces glare from
ambient light. The appearance of
each component on the shield is tied
to a functional aspect.

The first one was that dentists really
liked the full head harness. The users of the safety helmet prototype
commented that, compared with
their current face shield with an elastic band, the full safety harness was
more comfortable, secure during
long operations and caused fewer
headaches. When analyzing this
feedback, we realized that the key is
the top strap. It supports the weight
of the face shield and alleviates pressure on the sides of the head.
The second discovery was that a
square rim has better optical properties. Searching online, I came upon
an image of a face shield where the
visor was gently curved in the field
of view. We wondered what would
happen if we extended that principle further, so we adjusted the shape
of our rim from a semicircle (curved
at the front) to a square (flat at the
front). From testing, we realized that
this reduced optical distortion and
minimized glare from ambient light.
As optical clarity is paramount to
dental professionals, we thought this
would be a great feature.
The third discovery was of an optical
plastic technology initially developed for iPhone screen protectors. It
turns out that the functional requirements of screen protectors, which
are ultraclear and scratch-resistant,
are similar to those of dental face
shields. Combing this optical plastic
with our square rim has resulted in a
face shield that is virtually invisible
and incredibly durable.

◊Page 6
The next-generation Loupe Shield
available today incorporates these
three discoveries. It features a fully
adjustable head harness with a top
strap, a square rim with a flat front,
and a visor that was coated using this
optical plastic technology.
It’s hard to know when a product is
ready for market. As a designer, the
tendency is to continue to improve
it, but this cannot go on forever; at
some point you reach a local optimum. After completing the 58th
prototype, we 3D-printed ten shields
and sent them to dentists in the U.S.,
Canada, the U.K. and Germany. Eight
of the dentists loved it. Common
startup wisdom is that, if even one
customer loves your product, it’s
time to go to market, so that is what
we did.

Dr. Yamaoka, how did collaborating with your son, an engineer,
help achieve the final result?
Dr. Scott Yamaoka: Being able to
express the clinical needs for shield
protection and functionality to a
design engineer whose training is
to take a concept and bring it into
reality has been invaluable. Zach
was able to take a complicated prototype and simplify its design while
addressing the key needs for clinical
practice.

Securing appropriate PPE has
been quite challenging for many
dental professionals in the past
year. Why should dental teams be
excited about this invention, and
how will it improve their workflow?

Dr. Scott Yamaoka: Using a face
shield that had poor clarity, was
frequently fogged and felt uncomfortable slowed down my work.
Zach and I designed the Ambience
face shield to tick off all the boxes
of what I would want a face shield
to be. When using it, I can achieve
my pre-COVID-19 level of efficiency,
with the added benefit of protection.
Owing to its optical clarity, it does
not affect the patient experience
and interaction.
I sometimes forget I am wearing it.
Eye strain and neck issues have also
improved for me, which is a benefit
I expect others will experience as
well.
Having the shield gives me the peace
of mind to focus on the surgery and

the patient. The benefits can be seen
after surgery when the plastic face
shield is covered with bioburden on
the outside. Wearing the shield is a
seamless minor inconvenience, as
I am now much more aware of the
ramifications of splatter on my face
and loupes. This face shield has become an integral part of my practice.

Should dental professionals keep
an eye out for new products?
Dr. Scott Yamaoka: The Loupe Shield
is fantastic at keeping splatter and
droplets off the clinician’s face. It
does this without sacrificing comfort or clarity. One shortcoming of
face shields, in general, is that, alone,
they do not provide sufficient protection against aerosol. The clinician should still wear a respirator
or mask. Some face shield products

completely seal around the head to
provide aerosol filtration. However,
they are overly complex, hard to
clean, don’t fit loupes and are pricey.
As more data indicates the importance of aerosol as a mode of transmission, the desire for face shields
that can protect from both splatter
and aerosol will likely increase. For
now, the Loupe Shield with an N95
respirator is perfect for a clinician
working in a high-concentration
aerosol environment. In the future,
developing a Loupe Shield that offers complete protection from both
splatter and aerosol would be a natural progression.

GENERAL DENTISTRY

The trick to profound hemostasis is simple: scrubbing of copious amounts of hemostatic agent
against the bleeding tissue. Scrubbing removes the superficial coagulum, ensures that fresh agent is constantly available to meet the blood
oozing from the capillaries, and forces the coagulum deeper into the capillary openings – as long as there is
enough agent to meet the challenge.
Combining the ease of application
with scrubbing force is most effec-

About the author
Leo Tjäderhane, DDS, PHD
Leo Tjäderhane completed his DDS degree in 1986, PhD in 1995 and received
the speciality in Cariology, Restorative
Dentistry and Endodontics in 2000, all at
the University of Oulu. He is a professor in
cariology and endodontology.

The ”scrub and wash” technique
helps to achieve complete and longlasting hemostasis in less than a
minute, even in the most vigorously
bleeding and inflamed gingival tissue. The tissue will now tolerate a
matrix, etching acid and adhesives
without the risk of bleeding. Time
well spent to ensure conditions that
allow high-quality restorative work.
Hemostatic agents and coagulum
remnants have been suggested to
affect the bonding strength1,2 and
marginal integrity 2 of the restoration. With ferric sulfate, acid etching
is sufficient to remove the potential
remnants to allow appropriate bonding2 and good marginal adaptation3.
When self-etch adhesives are used,
cleaning the surface with Consepsis
Scrub (Ultradent Products) containing 2% chlorhexidine gluconate is a

At this point, a retraction cord can
be placed if needed (Fig. 5). It can be
soaked with the hemostatic agent;
though my personal preference is
to use it dry whenever possible. Placing the cord into a bleeding sulcus is
both difficult and, in many cases, ineffective since the hemostatic effect
of a relatively small amount of agent
soon wears out.

Fig 3. Metal Dento-Infusor tip delivering the hemostatic agent right at the orifices of the bleeding capillaries. Constant application of
the hemostatic agent with the pressure and brushing movement, creates the coagulum that closes the capillary orifices.

Fig 4. Vigorous washing effectively removes the loose coagulum that could mask slight bleeding underneath. The gingival margin is
dried with the air/-water syringe and observed in case some localized bleeding still occurs, which and requires further scrubbing of the
hemostatic agent.

© Dr. Jessop

Hemostatic agents are coagulants,
causing the agglutination of blood
proteins. The reaction is instant, but
the mere contact of the agents with
the bleeding surface results in only
superficial coagulation. And this is
where we dentists often make the
first mistake. We are afraid of damaging the gingiva, thus we only gently
apply the agent e.g. with a plastic
brush tip or with the tip of the instrument. Alternatively, we may
place a cord soaked in the agent into
the bleeding sulcus. Both techniques
are rather ineffective since the effect
of the small amount of agent is overwhelmed by the constant bleeding.
Even if the bleeding seems to stop,
the slight touch of an instrument,
placing the matrix band, or applying the etchant gel easily provokes
it again.

Fig 2. Metal Dento-InfusorTM tip allows delivery of pressure and
a brush for scrubbing.

Actually, hemostatic agents – at least
the best of them – work very well if
we use them correctly. Let me share
with you a clinical trick I learned
from Dr Dan Fischer more than 20
years ago, which I’ve been successfully practicing since.

After 5-10 seconds of scrubbing, depending on the extent of bleeding,
the gingival margin is washed, not
only to remove the coagulum but
also to test the hemostatic effect.
This is the step in which we dentist
often make the second mistake. Being afraid to introduce new bleeding, we tend to be too cautious with
our washing. Instead, we need to
wash vigorously to remove all loose
coagulum and to reveal the areas
where bleeding may still occur (Fig.
4). Only then are we able to identify
the areas where the capillaries are
incompletely blocked, where the
further application of the agent and
scrubbing is required. In most cases,
no more than two rounds are needed
to achieve profound hemostasis for
the whole working area. Then we are
ready to continue with the restorative procedure.

Have you ever had a Class V cavity preparation right at the gingival
margin ready to be restored, when
the gingiva starts bleeding heavily?
Several hemostatic agents are supposed to stop bleeding, and they do
– but if you even slightly touch the
gingiva with your instrument the
bleeding starts again. Frustrating,
isn’t it? Unless you are extremely
careful and very lucky, the restoration may easily be ruined (Fig. 1). At
least, your day is ruined.

containing Astringedent 15.5% ferric
sulfate (Ultradent Products) or Astringedent X 12.7% iron solution (Ultradent Products), allowing constant
and controlled application of the hemostatic agent during scrubbing (in
close contact with the bleeding capillaries; Fig. 3). The scrubbing force
required is approximately equal
to that required to scratch a lottery
ticket.

You may wonder if you should worry about damaging the gingival tissue with rather a vigorous scrubbing.

Well, don’t worry! You cannot damage the gingival epithelium. It has a
tensile strength of approximately 4
MPa5. If mechanical force could cause
permanent damage to the gingiva,
we couldn’t treat periodontitis. If
something comes loose during your
scrubbing, it is inflammatory granu-

lation tissue and the patient is better
off without it.

A CEREC Zirconia single crown
– Tooth 16 in 82 minutes
Primemill case study
By Dr Todd Ehrlich, USA

Case description
A 58-year-old male patient came
into our practice with a large carious lesion on the distal surface of
tooth 16. The tooth was previously
restored with a CEREC onlay in 2003
with a ceramic. It was doing well, but
the caries was large enough that a
new restoration was indicated for
the entire tooth. The large buccal
abfraction was also a concern for the
patient, so he wanted that covered
as well. While waiting for the anaesthetic, much of the digital work
could already be completed. With
the CEREC Primescan and the CEREC
Primemill it is now possible to complete two workflow steps simultaneously. After scanning and creating
the model, the margin was marked
and approved, and the proposal
was completed. The CEREC software
analyzed adjacent teeth to find the

best anatomical shape that fit the
patient. The milling strategies were
calculated, and the proposal was
displayed as it would be milled. The
design for the molar was sent to the
CEREC Primemill where the CEREC
Zirconia block and the milling burs
were ready to make a crown come to
life. The entire time for milling was
4:22 minutes. Zirconia can be milled
in Super Fast mode, resulting in sub5-minute milling which reduces the
overall process by approximately
10-15 minutes. Because the CEREC
Primemill and the CEREC SpeedFire
are seamlessly connected, the sintering cycle is automated and made
very efficient. Standard sintering
times can be as short as 18 minutes
depending on materials and proposal design. The manufactured restoration was easily cemented with a

After: Highly aesthetic full-surface zirconia crown

Final result

resin-modified glass ionomer. Total
treatment time was 1:22 hours, including preparation of the tooth and
fabricating the restoration.

Discussion
The CEREC chairside system has
always been known for its speed
in delivering a restoration. In this
particular case of a single unit, it requires usually just seconds of time

to image the preparation. After imaging, the biogeneric proposal takes
about 15 seconds. The clinician may
do minor adjustments and changes
of occlusion at his or her discretion.
Finally, at the point of cementation,
the clinical procedure is fast because
CEREC supports you in producing
predictable outcomes with regards
to the anatomy, interproximal contact, and occlusion. The advancing

technologies in zirconias are bringing out better aesthetics with every
generation. The design of the restoration enabled the restoration to fit
interproximally and occlusally without any adjustment.

Twenty years of DAC Universal: Dentsply
Sirona celebrates a sparkling clean success story
By Dentsply Sirona

DAC Universal has stood for excellent hygiene and safety standards for
20 years. A remarkable characteristic
in the field of dental solutions – as
remarkable as its mode of operation.
DAC Universal does not require
chemical cleaning agents but uses
only demineralised water for the reprocessing of medical instruments
– a feature that helps to preserve the
lifespan of instruments. Cleaning,
thermal disinfection or unwrapped
sterilization and optional lubrication: The fully compliant and automatic reprocessing cycle takes only
15 or 21 minutes, depending on the
programme. All cleaning steps are
standardised and fully automated at
the touch of a button, which significantly minimises application errors.

A success story since 2000 in
close cooperation with dental
experts
DAC Universal has been a continuous success with dental experts
worldwide. Not least because insights gained from working with
dental experts have helped to optimise DAC Universal for users. "By
engaging with dentists, we can offer
innovative ideas and safe solutions
that are tailored to the requirements
of everyday practice," says Michael
Geil, group vice president of equipment and instruments at Dentsply
Sirona.

In the anniversary year of Dentsply
Sirona’s successful infection control
solution, DAC Universal, the topic
of infection prevention is more relevant than ever. Seamless, excellent hygiene in dental practices and
clinics helps to give patients the
confidence to have preventive examinations and important dental
treatments.

In 2000, the launch of the first DAC
Universal changed reprocessing in
dental clinics. Five years later, the
first updated edition of DAC Universal entered the market, followed
by a new model again in 2009. By
2017, 40,000 DAC Universal units
had been installed worldwide. Over
the years, many technical improvements and upgrades have been
added, including the graphic display,
intuitive user interface, and the possibility to reprocess not only contraangle handpieces and turbines, but
also e.g. ultrasonic/sonic handpieces
and tips as well as nozzles of multifunctional syringes, and powder jet
devices and handpieces. Today, DAC
Universal meets the expectations of
dental professionals, offering professional care, cost-effective reprocessing, fully automatic reprocessing,
and legal certainty. The latest update
includes new features that enhance
user-friendly handling: touch display, LAN interface, guided Check &
Clean maintenance workflow. Ute
Wurmstich, technical sterilisation
assistant from Gilborn dentists in
Germany, summarises: "Living up
to the philosophy 'Inspired by your
needs', Dentsply Sirona is in constant
contact with the industry to develop

products that make our work and
daily routines safer, more efficient
and a lot easier. The result is visible
in the evolution of solutions like the
DAC Universal."

Classification “full virucidal activity” confirmed
A lab study from the independent
accredited test lab “HygCen Germany”, by Dr. Sebastian Werner and
commissioned by Dentsply Sirona,
recently confirmed on June 30, 2020
the full virucidal activity of the DAC
Universal family, including activity
against all enveloped and non-enveloped viruses.* Enveloped viruses
include SARS-CoV-2, hepatitis B and
hepatitis C virus, HI virus and influenza.
Werner, medical specialist for hygiene and environmental medicine,
states: “As far as I know, there is currently no other technical reprocessing unit of this size and speed on the
market in the field of dentistry that
could represent the bactericidal, levurocidal and virucidal activity in the
same way as a DAC Universal.”

DAC Universal D: Safe cleaning,
disinfection, and oil care
DAC Universal D, launched in 2019,
features an intuitive user interface
with its touch display. In approximately 15 minutes, up to six instruments are reprocessed fully automatically at the touch of a button.
“The advantages of the new model
are clearly quantifiable in time and
cost saving. Overall, the process time
is reduced by up to 46% compared
to the previous model. This means
that instruments are available again
sooner for the next treatment, and
practices also have to stock significantly fewer handpieces and contraangles," says Geil.
The new version offers two programmes to choose from: The Blue
Lid programme was specially designed for rotating instruments such
as turbines, handpieces, and contraangles. Reprocessing starts with a
cold pre-wash. Internal cleaning of
the spray and gear channels is followed by fully automatic oil maintenance of the gear channels. External
cleaning with the pulse-wash method removes dirt and deposits on the
outer surfaces of the instruments

DAC Universal S: All-in-one and
all-round protection
Launched in September 2020, the
new DAC Universal S completes the
DAC Universal product portfolio
with a sterilization function especially for markets that require sterilisation instead of a disinfection of
unwrapped medical devices.
The automatic programme selection allows for two programmes
that provide high process reliability.
The Pink Lid Programme is specially
designed for rotating instruments
such as turbines, straight and contra-angle handpieces. The cleaning
performance is excellent, and the results far exceed the standard values
(80% better) required by the Robert
Koch Institute (The Robert Koch Institute is a German federal government agency and research institute
responsible for disease control and
prevention). Finally, instruments are
sterilized at 134°C with three minutes
of holding time, and then cooled
with cold, sterile air.
The second programme, White Lid
programme, is used for instruments
that do not require lubrication: e.g.
ultrasonic and sonic handpieces and
tips or nozzles of multifunctional
syringes, and powder jet devices and
handpieces. The cleaning steps are
almost identical to the Pink Lid Program, but with the lubrication step
removed.
Geil, says: “With the DAC Universal
D and the DAC Universal S we have
completed the DAC family. Infection
control and instrument reprocessing
follow strict requirements all over
the world. With the DAC family we
enable the dental practice to meet
these requirements and to guarantee safety according to the legal and
technical standards in every market.
In times of COVID-19, it is a mandatory assurance of dentists to their staff
and patients helping uphold dental
care under trying circumstances.”

even more thoroughly than the predecessor model. Finally, the instruments are thermally disinfected and
cooled with cold, sterile air. The second program, Green Lid programme,
is used for instruments that do not
require lubrication: Ultrasonic and
sonic handpieces and tips, nozzles
of multifunction syringes, and powder jet devices and handpieces. The
reprocessing steps are identical to
those of Blue Lid, except that lubrication is not required.

The new DAC Universal D was launched in 2019 and features an intuitive user interface

The material of the future for all
kind of indications
Resin-based blocks beyond your imagination
By Dr Nicolas Guitierrez, Spain

Introduction
Implant prosthetics and dental prosthetics differ considerably, with the
absence of periodontal ligament in
the implant/prosthesis complex.
This situation causes mechanical
problems to the implants, especially
to the implant prosthetic material,
due the lack of stress absorption resulting from the normal impact during chewing1, 2. Among the problems
we face in daily practice is the unscrewing and fracturing of veneering material of the implant crown
and fracturing of implant/abutment
components.
It is very important to consider that
resin based blocks give us the miss-

ing part from ceramic materials to
solve the problem of anterior exposure. It is also necessary to consider
the importance of reliable bonding
union between the resin block and
the abutment component of the
implant, because the right transmission of occlusal load depends on the
reliability of this bonding interface.
One of the biggest advantages of
BRILLIANT Crios blocks is the combination with ONE COAT 7 UNIVERSAL, the best bonding system for the
resin based blocks according to the
scientific literature3, 4 and also tested
in my own practice over the last five
years of use.
Another very important feature is
the size and distribution of ceramic
fillers. We have learned from the past

that bigger size fillers are better for
the strength but, at the same time,
are more prone to detach from the
surface creating craters iniciating
the material degradation. A homogeneous filler size and distribution is
much better for the material’s wear,
luster, aesthetics and strength over
long term.

Case 1
During daily practice, it is very common to face situations where the
implant has to be placed lingually
due to normal resorption (Fig. 1) of
the buccal plate after the extraction.
But, at the same time, it is not necessary to perform bone grafting procedures. The result of this scenario is to
increase the stress on the implantbone complex when we use rigid

materials like conventional ceramics
(Fig. 2). For this daily practice situation, the combination of rigid and
resilient materials against the antagonist, allows the stress to the implant-bone complex to be reduced
(Figs. 3 & 4).
Oblique loads have been reported to
increase stress values in peripheral
bone and prosthetic components
also generating high stress in the
crown, implant, abutment, and cortical bone. The Young’s modulus, also
known as elastic modulus, is one of
the important factors determining
a material’s behaviour5.

Case 2

well known that the big issue is chipping and delimitation of the ceramics, due to the high forces applied in
the patient with dental implants. In
regards to this problem, the combination of rigid materials to support
the connectors and resilient materials to absorb the shock and, at the
same time, allow easy fixation, make
the use of resin based blocks the logical choice for this kind of restoration.

Case 3
In this case, a patient presented
with extremely atrophic bone in the
mandible, with four short implants
placed between the dental nerve

Another common situation is a fullmouth restoration over implant. It is

boat—my only possession, back then—in
order to raise an initial capital of 5,000 Finnish marks, which is roughly the equivalent of
€7,000 today.

One of the biggest challenges in the beginning was simply putting Finland on the map
and getting the word out about Finnish dental
products. It was not only our company that
was unknown but also our country of origin.
Many of our customers had no idea where we
were located; however, little by little, we began
to gain a foothold in the industry.

What have been the greatest milestones in
the history of Planmeca?
Businesswise, I would say that the achievement that I am personally the proudest of is
that of having secured the largest individual
sales deals in the history of dentistry. Planmeca
entered the US market in 1983 with the sale of
10,000 patient chairs, and we delivered over
1,000 dental units to Saudi Arabian dental
institutions in 2012. In terms of technological
innovations, one of our most significant milestones was the development of the Planmeca
Dimaxis all-in-one software concept in the
1990s. It really was a groundbreaking and bold
innovation at the time and was launched long
before the term “software ecosystem” became
a buzzword. The Dimaxis concept paved the
way for many new ideas that would further
improve the daily dental workflow.

PATIENT

Back in the 1960s, when I was working as a
sales representative for a Finnish dental supply
company, almost all dental products sold in
Finland were imported. I realised that—especially when it came to patient chairs—the design and ergonomics of these products could
easily be improved. That is why I decided to set
up my own business. I thought, “Why not start
manufacturing products of our own?”

However, having realised that the Finnish dental market simply was not big enough to build
upon, I immediately aimed for the international market. Today, there are only around 4,000
dental professionals in Finland, whereas the
number is close to 2 million globally. Luckily, I
had the opportunity to take part in the International Dental Show in Munich in 1971. I exhibited my first products at the fair—an ergonomic
dental stool and an instrument cabinet.

I am also extremely proud of our algorithm
expertise. We have already managed to lower
patient doses considerably and cancel from 3D
images the effects of patient movement. We

continue to work tirelessly to keep introducing
new innovative algorithms that will further
improve image quality and help to provide the
best basis for diagnosis.

Today, Planmeca is one of the world’s largest privately-owned dental manufacturers. Have you ever been tempted to sell the
business or to consider consolidation with a
larger dental group?
Quite frankly, no. Naturally, we have received
many offers over the years, but selling a company that is the result of the life’s work of so
many people is not a decision one would take
lightly. We also want to preserve our independence—the independence to change our course,
if needed, to make fast decisions and product
modifications based on the feedback that we
receive from customers, and to invest in new
companies and product development.

Planmeca rapidly expanded its international business as early as the 1980s with the
establishment of subsidiaries in the US, Italy
and Sweden; and yet your headquarters has
remained in Helsinki. How has being located
in Finland contributed to the success of the
company and how important has investment in the national economy been for you?
I have always believed in Finnish know-how
and education. Despite our global success, I
wanted to keep the company’s production located in Finland in order to preserve the agility,
low hierarchy and entrepreneurial spirit that
has defined the company from its early days.
When everything is in close proximity, it is so
much easier to make fast decisions and product modifications. Also, Finnish design is recognised around the world, and this has always
been one of our key competitive advantages.
For me, above all else, financial success means
that I am able to secure the workplaces of my
staff and create new career opportunities for
young people in Finland.

What is a typical working day for Heikki
Kyöstilä?
Before the pandemic, I used to spend around
100 days every year travelling for business—
meeting our customers and partners around
the world. Meeting them in person has always
been the spice of my working career. Naturally,
those meetings are now taking place online.
Every day is different in this fast-paced company and industry. I really like to take the time to
talk to my staff, to visit our production facilities
and to stay up to date with whatever is going
on in each department—whether it be product
development, design, marketing, production
or human resources.

Dentsply Sirona invites innovative
female dental experts to apply for this
year’s Smart Integration Award
efficient and practical workflows at
treatment centers.

By Dentsply Sirona
Dentsply Sirona’s second Smart Integration Award competition is now
open for entries. The competition
underlines Dentsply Sirona’s commitment to the advancement of
women in dentistry by showcasing
and honoring their novel treatment
concepts and ideas for the future.
The award celebrates the achievements of women in dentistry.

Dr. Ginal Bilimoria, Smart Integration Award 2019 winner from Auckland, New Zealand said that, "The
concept of the Award intrigued me.
It was about efficient, intelligent and
integrated workflows using smart
networked processes; something I
was interested in. And I love the idea
of the award being open to women
from all over the world. When a
group of women get together to discuss dentistry, the dynamic is often
quite different as we open up and
share more easily about our struggles and successes."

The application phase for Dentsply
Sirona’s second Smart Integration
Award started in April 2021. The
award recognizes visionary treatment concepts and outstanding
achievements by women in dentistry and creates a platform for an international network of talented female
dental experts.
This year, for the first time, not only
female dentists but also female dental technicians are invited to apply
by June 28, 2021 with their ideas for
collaboration between the practice
and the dental lab. A jury of Dentsply
Sirona executives and renowned external experts will evaluate the entries. The award ceremony is scheduled for the end of the year 2021.
"We want to support women in all
areas of dentistry by ensuring we
understand their needs and support the development of their skills.
The visionary thinking of talented
female dental professionals drive innovation in dentistry and help deliver the best patient experience," said
Lisa Yankie, senior vice president
and chief human resources officer &
communications at Dentsply Sirona.

How to apply

Advancing digital dental technology through a dialogue
with users
The Smart Integration Award honors
creative ideas and successful treatment concepts of female dental experts. These include, for example,
ideas on how to improve the treatment experience for patients during diagnosis and therapy or on how
optimally networked and efficient
workflows could look in the practices
and dental labs of tomorrow.

"With the Smart Integration Award,
we want to integrate the expertise
and visions of female dental experts even more strongly into product development,” said Susanne
Schmidinger, director global brand
marketing enabling devices at Dentsply Sirona Digital Solutions Marketing. “In many countries, today, over
50% of students at dental faculties
are women, with a rising tendency.
It is important to enter into dialogue
with female dentists and especially
with young dental professionals.

Their creative potential will significantly influence the future of dentistry," Susanne explained. "Dental
experts who embrace change and
progress are invaluable partners in
helping us to develop future innovations that serve the needs of practitioners in every detail."

My workdays are still quite long; for
me, however, the dental business is
both a career and a hobby. When I do
have the time, I enjoy playing golf—
in Helsinki in the summer and in
Spain in the wintertime.

Despite the economic consequences of the COVID-19 pandemic, the
Planmeca Group achieved sales
of €764 million in 2020. How has
Planmeca stayed strong throughout the last twelve months and
what kinds of changes has the
company undergone so far during
the pandemic?
No one could have imagined the
events of 2020—it was a year unlike
any other. They say that necessity
is the mother of invention, and we
certainly had to discover new ways
of working and of interacting with
our customers. When the pandemic
began, we quickly realised that we
must move customer interactions
online. As a starting point, we organised a full series of webinars in
several different languages as part of
our new Time to Learn training con-

cept. These webinars have allowed
our customers to further improve
their expertise and to make the most
of their Planmeca equipment. Webinars have proved to be an effective
way for us to cover highly topical
themes such as infection control. We
have already organised over 100 webinars in different languages.
All in all, we have been lucky that
many of our customers have been
able to keep their services open most
of the time—at least partly—and the
need for dental care has certainly not
diminished despite the changing
world.

Before the pandemic, Planmeca
participated in thousands of dental events, trade fairs and congresses worldwide. How have you
managed to build and maintain
relationships with your customers and partners over the past
months?
Indeed, it has always been very important for us to meet customers
at events around the world and,
especially, to welcome guests here
in Helsinki. Before the pandemic,
thousands of dental professionals
visited our headquarters every year.

This has not been possible during
the pandemic and we have had to
arrange these meetings virtually,
which has actually brought us even
closer to our customers in many
ways. For example, we took our
popular Digital Dentistry World Tour
online for the first time ever. It was a
completely new type of dental event
that was streamed in eight languages. Thousands of viewers from over
100 countries were able to tune in at
the same time, and it was quite exciting to meet so many of our customers at once.

What lies in the future for Planmeca, and where do you see the
company’s greatest potential for
growth in the near term?
The future is certainly looking bright.
We have several interesting dental
and medical projects underway in
our R & D department. We continue
to deepen our knowledge, expertise
and involvement in different specialty areas, such as orthodontics,
medical imaging and new 3D applications. This will allow us to explore
new technological possibilities and
business opportunities.

What do you do when you’re not
running one of the world’s largest
dental companies?

Heikki Kyöstilä founded Planmeca in 1971. As the company marks its 50th birthday,
Dental Tribune International asked Kyöstilä if he had ever considered selling the successful dental business, to which he replied: “Quite frankly, no.”

At the age of 75, is retirement an
option for Heikki Kyöstilä?
For me, Planmeca is a way of life and I
certainly do not see retirement as an
option anytime soon. I want to continue to stay close to my customers
and staff, and I want to be involved

in everything that is going on in
the company. Working together
with dental professionals towards a
mutual goal of better patient care is
truly rewarding.

Study finds SARS-CoV-2 vaccine hesitancy
in 23% of healthcare workers

be vaccinated as an important step
in protecting their patients, their
communities and, of course, themselves.”

continuing to roll out vaccination
programmes and encouraging the
public to get vaccinated, one thing
is clear: there are still people who
refuse or delay their vaccinations.
Healthcare workers are a priority
group since they run an elevated risk
of infection. However, in a recent
study, researchers found that vaccine hesitancy prevails in around a
quarter of healthcare workers in the
UK and that, compared with their
white British colleagues, some ethnic
minority groups show more resistance to getting vaccinated.**
The UK Research study into Ethnicity And COVID-19 outcomes in
Healthcare workers (UK-REACH)
study is among the largest and most
comprehensive vaccine hesitancy
studies to date and was launched
after mounting evidence showed
that people from ethnic minority
backgrounds had double the risk of
severe COVID-19 disease compared
with the risk for the white population. The research is funded by UK
Research and Innovation and the National Institute for Health Research
and supported by large national professional regulatory bodies.

LONDON, UK: As world leaders are

In the largest vaccine hesitancy study outside the US and the only one to study UK
healthcare workers, researchers have recently analysed the link between ethnicity and
vaccine hesitancy and found that some ethnic minority groups are more likely to refuse
or delay a vaccination than their white British colleagues.

In light of the findings, the researchers urged the government to develop strategies that would help build
trust among ethnic minority groups
and dispel myths surrounding the
SARS-CoV-2 vaccine in the respective
communities. They concluded that
any communication regarding public health should be inclusive and
that the government should promote vaccination through trusted
websites.
Commenting on the results, General Dental Council (GDC) Executive
Director of Strategy Stefan Czerniawski said in a press release: “We
encourage all dental professionals to

The study, titled “Ethnic differences
in SARS-CoV-2 vaccine hesitancy in
United Kingdom healthcare workers: Results from the UK-REACH prospective nationwide cohort study”,
was published online on 28 April

Czerniawski commented that the
GDC will continue to seek opportunities to promote a wide vaccination
take-up and to show their support
for the findings of the study. Addi-

In the study, the researchers analysed ethnic differences in SARSCoV-2 vaccine hesitancy among
11,584 healthcare workers. They considered factors such as demographics, vaccine trust and perceived risk
of COVID-19 and found that, despite
the increased risk of infection, 23%
of the participants reported vaccine hesitancy. Healthcare workers
from Black Caribbean (54.2%), Mixed
White and Black Caribbean (38.1%)
and Black African (34.4%) ethnic
groups were found to be significantly more hesitant than white British
healthcare workers, of which group
21.3% were found to be hesitant.
According to the data, independent predictors of hesitancy include
younger age, female sex, a higher
score on a COVID-19 conspiracy beliefs scale, lower trust in employer,
lack of influenza vaccine uptake
in the previous season, previous
COVID-19 and pregnancy. After analysing qualitative data from 99 participants, the researchers also found
that there was a lack of trust in government and employers among the
participants. Additionally, the participants expressed safety concerns
owing to rapid vaccine development,
lack of ethnic diversity in vaccine
studies, and confusing and conflicting information.

“This research shows that most
healthcare workers—including dental professionals—recognise that
vaccines are safe and effective, but
that a minority remain hesitant. It’s
important to understand the reasons for that so that concerns can be
addressed, and take-up encouraged,”
he added.

tionally, the organisation has recently updated its vaccination guidance
for dental professionals and employers and encourages dental professionals to read it.

Children with immune deficiencies more
likely to develop periodontal disease
By Iveta Ramonaite, Dental Tribune International
LONDON, UK: Primary immunodeficiency
(PID) is characterised by a missing or poorly
functioning part of the body’s immune system. Inherent from birth or acquired later in
life, the disorder inhibits the body’s ability to
fight all types of infections. New research has
also found that, since children with PID have
no natural defence against the oral microbiota
that cause periodontal disease, they are more
susceptible to developing gingivitis than systemically healthy children.

According to a report published in the Journal
of Translational Immunology, 4,758 patients
had been entered into the UK Primary Immune Deficiency registry by August 2017. As
detailed in an editorial published in Frontiers
in Immunology last year, the worldwide incidence of people with PID is one in 10,000,
and the disorder is more prevalent in children.
Although the incidence rate is comparatively
low, researchers have identified more than
300 diseases associated with PID to date, which
is why its complications vary greatly, depending on the type of the disorder the patient has.

Since children with PID are more prone to developing frequent, severe infections that compromise their overall health, more research
needs to be done to improve understanding of
the diagnosis, symptoms and treatment of the
disease.

Primary immunodeficiency and oral
health
In a recent study, researchers assessed the link
between neutrophil-related PIDs and the presence of periodontal and other oral diseases, as
well as the response of children with PID to
periodontal treatment.

AD

“The motivation came from seeing some very
young children with advanced periodontal
disease and poor response to treatment. Some
of them ended up with dentures from a very
young age, hence the need to better understand the mechanisms of the disease,” lead author Dr Luigi Nibali, professor of periodontics
at King’s College London, told Dental Tribune
International (DTI).
The study was carried out at Great Ormond
Street Hospital and the Royal London Hospital by researchers from King’s College London
and Queen Mary University of London and
included 24 children aged 4–16 with PIDs and
24 age-matched children without PIDs. All
children underwent a dental clinical examination which included measuring periodontal
pocket depths, clinical attachment loss and
bleeding on probing.
The researchers found that a certain level of
dental caries in the mouth, which usually does
not pose a threat to systemic health, leads to
gingivitis in children with PIDS.
“The prevalence of oral conditions and periodontal diseases has been known to increase
in children affected by PIDs as they seem particularly susceptible due to the crucial defensive role of neutrophils against periodontopathogenic bacteria,” said co-author Dr Hiten
Halai, a clinical lecturer in periodontics at
King’s College London, in a press release.
“Furthermore, their response to periodontal
treatment is highly variable, and the presence
of periodontitis often leads to early tooth loss.
However, most published papers on this so far
consisted of case reports, with a lack of good
evidence,” he added.
The study also found that children with PIDS
had increased chances of suffering from oral
ulcers. When asked to elaborate on the finding, Nibali told DTI that little is known on why
children with PIDs often develop oral ulcers
but that it might be related to their immune
response and explained that it was a coincidental finding.
He also noted that although the findings are
not novel, the study offers strong evidence on
the topic. Therefore, he thinks it is crucial that
future studies delve deeper into understanding the link between PIDs and periodontal
disease and oral mucosal lesions. This, in turn,
could improve the prevention and management of the disease and improve the quality
of life of children with PIDs, he believes. Finally, Nibali thinks that further research could
also help find ways to relieve the systemic inflammatory burden resulting from inflamed
gingival tissues in children with PID.
“The study shows that children with PIDs have
a more severe response to dental caries, which
can potentially lead to advanced periodontal
disease. However, if the PID is controlled and
good oral hygiene and interceptive treatment
are achieved early on, the high susceptibility
does not necessarily result in tooth loss,” Nibali concluded.
The researcher team is planning to continue
working on understanding the genetic–microbial basis of problems related to the periodontal health of children with PIDs.
The study, titled “Periodontal status in children with primary immunodeficiencies”, was
published online on 3 April 2021 in the Journal
of Periodontal Research, ahead of inclusion in
an issue.
