MDM launches new look website
Chris Jenkins

Modern Dentistry Media (MDM) has gone
live with an improved and revamped
website that is more user friendly,
aesthetically pleasing and interactive. With
the advent of more platforms to access the
internet and better internet connections
with faster speeds now the norm across the
globe, it was paramount for MDM to update
their website.
MDM owner and publisher, Ursula
Jenkins, said, “As MDM has evolved over the
years, it was important for our website to
reflect our international expansion, as well
as the high standard of our publications and
services.” Key changes to the website also
include allowing internet users access to

MDM’s range of publications, archived
issues and articles. Readers can now also
participate in the CPD programme online.
Having a website is pertinent to
continually growing business in a world that
is becoming more and more technologically
developed. Jenkins sees that MDM’s website
is key to keeping the doors open to the rest
of the world, “We are continually forming
new relationships and partnerships
internationally - both with the dental
profession and the dental industry. Our
journals are read in Africa, Australasia, Asia,
Europe, Middle East and the United States.
The website is often used as a tool for
internationals to interact with us.”
The website also offers companies,

institutions and associations the opportunity
to advertise their products, services and
activities. This is an important new addition
to the website. A new feature that will be
implemented is one which enables a dental
professional who is reading the journal
online to click on an advertisement that gets
their interest and be automatically
re-directed to that company’s website. This
makes it easier and quicker for the reader
to find out more about the product/s and
even make online purchases from the
specific company.
The upgrading of the website reflects
MDM’s commitment to a high level of
dentistry. To view the website visit:

Successful root canal treatment possible
with basic equipment
Dental Tribune International

WITTEN, Germany: Researchers from
Germany
have
investigated
the
effectiveness of basic root canal
treatment (BRT) with tactile working
length determination compared with
BRT
with
standard
radiographic
working length control. They found that
tactile working length determination
achieves
comparable
treatment
outcomes in terms of radiographic and
clinical outcome parameters and is an
accurate method in BRT.
Researchers
from
Witten/Herdecke
University conducted their study in the
course of the university’s Gambia dental
care programme, which was established in
1995 and provides dental care to people
living in isolated parts of the West African
country, where modern medical technology
is mostly non-existent.
In the study, BRT performed without
radiographs was applied to a test group.

For the treatment of the control group,
X-rays were taken to facilitate working
length determination. In total, 70 patients
were followed up over a period of two
years.
At the end of treatment, participants in
both groups were examined using X-rays.
Tactile working length determination
proved to be as effective as radiographic
working length control: 24 months after
treatment only one tooth in the test group
had been lost. “Basic root canal treatment
can help to preserve even teeth with major
substance loss. Thus, it can help prevent
preterm removal of teeth,” said Dr
Anna-Louisa Holzner, a dentistry graduate
of the university. For her doctorate,
Holzner developed a method that enables
root canal treatment without electricity
and water, and with only minimal
materials and tools. The initial results of
this so-called BRT were published in the
International Dental Journal in 2009.

Several times a year, dental students and academic staff of the university travel to Gambia to
continue ongoing research projects in collaboration with the Ministry of Health of the Republic of
Gambia and the WHO. (Photo: Witten/Herdecke University)

The current study, titled “Clinical
effectiveness of basic root canal treatment
after 24 months: A randomised controlled
trial”, was published online ahead of print
in the Journal of Endodontics. DT

BARCELONA, Spain: Procter & Gamble’s
Oral-B toothbrush brand has introduced
a new electric toothbrush that uses
Bluetooth 4.0 technology to connect to a
smartphone application. The toothbrush
was presented on Monday at the opening

of the 2014 Mobile World Congress in
Barcelona, a major event in the mobile
industry.
According to P&G, the toothbrush is the
first of its kind. Using Bluetooth 4.0, the
interactive device connects to the respective
Oral-B
application,
which
provides
real-time guidance while the user is

brushing. It records and stores brushing
activity as data that can be shared with the
dentist to achieve more personalised
brushing routines.
Dental professionals can program their
patients’ brushing routines in the application
to help them focus on problem zones in their
mouth. Users of the toothbrush can use their
smartphone as a kind of remote control to
customise it to their needs.
As reported by P&G in a press release,
preliminary tests of the application have
shown that when connected brushing time
increases from less than 60 seconds with a
manual toothbrush to more than 2 minutes.
The technology will be made available in
a variety of Oral-B electric toothbrushes,
including the new Oral-B SmartSeries.
However, it will be sold initially in limited
quantities in Germany from spring. The
company announced that it will be
distributing the new interactive toothbrush
globally from June. The new smartphone
application will be available in iOS in May
and in Android in August.
The 2014 Mobile World Congress ran until
Thursday, 27 February. This year, more than
1,700 exhibitors are showcasing their latest
product innovations. In 2013, the congress
and its exhibition attracted more than
72,000 visitors. DT

Interview: Research with
the SYSTEM Initiative
Chris Jenkins

DTSA: With your findings challenging the
supremacy of silver amalgams in
dentistry, how do you see this affecting the
dental trade from the dentist’s point of
view and from the dental manufacturer’s
point of view?
Dr Mickenautsch: This is an interesting
question and may best be answered by
members of the dental industry.
What is the typical length of time it takes
to complete a research project that you
and your team commit to?
Our projects may take between 6 months and
2 years until completion.
What other research projects are you
currently working on?
We have just completed a systematic review
regarding the failure rate of high-viscosity
(reinforced) glass-ionomers in comparison to
composite resin for load-bearing posterior
tooth restorations.
We are further investigating, in collaboration
with colleagues in the United States, the
accuracy of a novel statistical test for routine
detection of selection bias in randomised
control trials (RCT) and during the past year,
SYSTEM’s research work focused on the
appraisal of clinical merits for Chlorhexidine
in the prevention of infection after tooth
extraction; the use of the alcohol-sugar Xylitol
in preventing tooth caries and the clinical
failure rate of using resin-based glass-ionomer
cements (RM-GIC) for orthodontic bracket
bonding. The later relates to the lower

incidence of carious decay associated with
orthodontic treatment when RM-GICs are used
instead of resin-based adhesives. However,
common belief considers the use of RM-GIC as
less effective for bracket bonding. In contrast,
our systematic review found no difference in
the failure rate between RM-GICs and
resin-based adhesives after up to 14 months.
Xylitol products are increasingly presented as
being equal to fluoride in their caries
preventive effect. Our systematic reviews show
that such optimism may be premature.
Chlorhexidine as an antibacterial agent may,
when used under certain application regimes,
prevent infection after tooth extraction.

“

We hope that our systematic
reviews and their regular
updates by us assist health
care providers in finding
answers to clinical questions
in daily dental practice

”

Through another systematic search of the
dental literature, we found 95 clinical
studies that investigated the retention rate
of resin-based fissure sealants and
subsequent
caries
occurrence
on
resin-sealed teeth. Based on the combined
data of these trials we compared the caries
predictive power of losing resin sealant
material in pit and fissures to the predictive
power of mere random guesses. To our
surprise, no significant difference beyond
the play of chance was found, thus sealant
retention loss appears not to be a valid

Dr Steffen Mickenautsch, Research programme leader: SYSTEM Initiative/Department of
Community Dentistry, Faculty of Health.

predictor for developing tooth caries. While
these results do not question sealant
retention as a beneficial factor for caries
prevention, they shed grave doubts on the
justification of its status as ruling quality
criterion for pits and fissure sealants. The
conclusions of these findings suggest the
need for adopting clinical outcomes, such as
the caries occurrence rate in formerly sealed
teeth as ruling quality criterion for pit and
fissure sealants, instead of the commonly
used sealant material retention rate.
Having conducted a vast number of
reviews, updates and evidence reviews on
a number of topics, how influential is
SYSTEM in the dental world?
We hope that our systematic reviews and

their regular updates by us assist health care
providers in finding answers to clinical
questions in daily dental practice.
Do Wits Dental students get to contribute
and participate in your research?
Yes, we had the collaboration of
post-graduate/master students in the past
and are currently preparing aspects of our
work for future student input and training.
Have you got any other interesting
information about SYSTEM that the
dental world might not be party to that
you could share with us?
We regularly share news of our researchoutput online on

Interview: Dentistry
working with the
internet and technology
Chris Jenkins and Bridges MC.

Dr Barry Freydberg, is a renowned expert on
the internet, cloud technology, and digital
dental technology, whose presentations have
received critical acclaim at conferences in
the United States of America and Europe. He
will be presenting a talk on this subject at
IDEM Singapore 2014. Dr Freydberg will
cover a variety of topics including how to
optimise a practice’s use of technology and
the internet, eliminating paperwork, taking
practice management to the Cloud, and
using Facebook as a marketing tool
DT SA: How important is the internet and
technology to the modern dental practice?
Dr Freydberg: It is critical on so many levels!
I do not know where to begin. Our personal
office records have been electronic for several
years, as are the diagnostic radiographs,
charts and so forth. In addition, the internet
allows us to share data with specialists and
other providers. We also use the internet for
marketing and patient communication. When
I see practices without electronic records and
the use of the internet, I am frustrated for
them, as I know what they are missing out on
and how their lives would change if they
embraced technology.
Which are the three areas in which the
internet can make the biggest impact on
how a practice operates?
There are really several arenas of internet
usage. Today, marketing and communication
to existing patients and to prospective
patients has become of paramount interest to
a practice. This includes the use of Facebook,
Websites, Search Engine Optimization,
electronic newsletters, patient education and
convenience. I’d say the top three are Social
Media, a Website which can attract patients,
and SEO which leads patients to the Website.
What would be your prediction for the
next technology to make a big impact in
dentistry?
That’s a tough one. 3D imaging affordably
and at higher resolutions than we have now
will make us much better diagnosticians and
clinicians. Also cost effective hard tissue

lasers. The ultimate gains will be in genetic
engineering and stem cell research. Let us not
forget that 3-D impressions will reduce costs
of materials and remakes, which will take
over traditional impressions very quickly.
How cost effective is it for a dental
practice to implement the latest advances
in internet and technology in terms of the
equipment required and the related cost
to the patient?
Great question. We all think that technology
and the internet costs money, when in reality
it saves money. So, on the patient side it
allows us to be more efficient for them,
enabling us to be more competitive with our
fees.

“

The tough economic climate is a
problem for all of us. So, we need
to educate the patients how
technology reduces costs.

”

Have you got a general feeling from
patients about the increased use of
internet and technology in a dental
practice? With regards to whether they
feel positive about it or are worried it
could increase fees?
I have never had a patient express concerns
that fees will increase due to the use of
technology or the internet. But we do get
complements from patients on using
technology. Everything from reduced
radiation to texting appointment reminders
are appreciated.
We are currently in a tough economic
climate worldwide. Why do you believe
that there is a link between dentists using
the latest technologies and profit when
there is a big chance many patients will
not go to the dentists to save money
because of perceived higher costs due to
the dentist becoming more technical?
The tough economic climate is a problem for

Dr Barry Freydberg.

all of us. So, we need to educate the patients
how technology reduces costs.
What is your view on the impact internet
and technology is having on dentistry in
growing economies such as South Africa?
This begs a philosophical answer about
technologies being introduced to an area
which is just beginning to embrace
technology. In a growing economy,
technology “leapfrogs” into the latest
technologies of today. This occurs faster than
in highly technological regions of the world,
where technology evolves on top of what
already is being used.
An example might be this. In the early 1990’s,
the USA had analogue phone systems. It
slowly evolved into digital phones and
communications. In Russia at that time, there
were barely any phones in homes. When they
began to emerge, they didn’t go to analogue
and then digital, they “leapfrogged” over the
analogue and started at the digital level. This
happens with all technologies.

“

those that live in rural areas often live
very far away from the nearest
healthcare facility. In addition, poverty
is prevalent amongst these South
Africans which makes it difficult for
them to pay for dental care. Do you
foresee that in a situation such as ours
which is also similar to other African
countries that digital dentistry and the
use of the internet and new technology
can provide dental care for these people
with the help of the government?
I have just returned from an amazing trip to
SA a couple of weeks ago. I visited those areas
with little infrastructure as well as rural areas
and of course the big cities. The bottom line
seems to be that mobile internet access will
probably be the leader (smart phones and
tablets) with desktop computers following.
The government will do well to help fund
and bring these technologies to the masses.
Access to health care and health care
education through technology will help the
masses with digital clinical capabilities
helping to reduce costs.

In a growing economy, technology “leapfrogs” into the
latest technologies of today. This occurs faster than in highly
technological regions of the world, where technology evolves
on top of what already is being used.

South Africa has roughly 3500 dentists
and a total population of nearly 53
million (Census estimate 2013) people.
A vast majority of the population live in
urban
informal
settlements
or
townships with little infrastructure and

”

I truly felt that visiting SA was a highlight
of my life. I could feel that economic progress
and equality was rapidly progressing but it
will take time. DT

The ITI expands its
educational offering
Specialist implant dentistry continuing education courses launched in Brazil and South Africa
Basel, Switzerland, January 29, 2014 –
The International Team for Implantology
(ITI) has expanded its educational
offering by confirming two more ITI
Centers of Excellence in South Africa and
Brazil. As part of the ITI University
Programs, nine selected academic
institutions around the globe are now
providing 4- to 7-day continuing education
courses in implant dentistry, known as ITI
Education Weeks.
The two new Centers are located at the
University of Pretoria School of Dentistry
(South Africa) and Hospital Moinhos de
Vento (Porto Alegre, Brazil). Both
institutions have an established track
record for high quality continuing
education
courses,
state-of-the-art
facilities and draw on an outstanding
faculty of experts. The first ITI Education
Weeks in South Africa and Brazil will take
place in July and November 2014,
respectively.
The ITI Education Week in Pretoria will
be directed by Prof. Andre van Zyl, Head
of the Department of Periodontics and
Oral Medicine, and will cover all aspects
of tooth loss and factors influencing the
replacement of missing teeth as well as
the role of CAD/CAM and that of the
dental technician.
The ITI Education Week in Porto Alegre
will discuss aspects of tooth loss, its effects
on the oral cavity and the steps of several
clinical situations leading to the
rehabilitation of oral health using implant
dentistry. The course will be directed by
Dr. Waldemar Daudt Polido, an oral and
maxillofacial surgeon who has been
actively involved in the ITI for many years.
While all the ITI’s other Education Weeks
are held in English, the ITI Education
Week in Porto Alegre will be the first to be
held in Brazilian-Portuguese and Spanish,
addressing the urgent need to offer
continuing education courses in the local
language in Latin America.
“We are very pleased to have two further
highly regarded institutions on board and
also to finally be able to offer an ITI
Education Week in Africa and South
America. The Centers complement our
existing course offering very well and I am
sure they will be a great success”, says
Prof. Hans-Peter Weber, Chair of the ITI
University Programs Committee.
Also new in 2014 is the ITI Education
Week Melbourne. After having finalized
the construction of its new dental clinic,
the first course at the University of
Melbourne is coming up at the end of
February. It will be directed by Prof. Ivan
Darby and A/Prof. Roy Judge and will
focus on current perspectives in implant
dentistry.
ITI Education Weeks offer top-class
continuing education courses in implant

dentistry aligned to the ITI philosophy of
evidence-based treatment approaches.
They give practitioners the opportunity to
advance their knowledge and skills in

implant-related treatment and learn from
experts in the field. Participants benefit
from lecture and discussion sessions,
participation in treatment planning,

surgical and prosthetic hands-on sessions
as well as live surgical and prosthetic
sessions. Each ITI Education Week offers
continuing education (CE) credits. DT

The challenge in the aesthetic area
from the surgical aspect
Dr Schneider Gadi - DMD, Specialist in Periodontics
Alpha-Bio Tec Research and Academic Consultant

The ideal placement of a single implant or
of several implants in the aesthetic area

3. Implant insertion does not prevent buccal bone resorption

O-G
2 mm under the CEJ of the
adjacent teeth.

M-O
A minimum space of 1.5 mm should
be left from the adjacent teeth.

B-P
A minimum of 1 mm of bone should
be left at the circumference of the
implant.

Angulation
The implant faces an imaginary line
connecting the cingulum of the
adjacent teeth. If the implant is placed
buccally to this line, angulated
abutments should be used in order to
correct the angle.
Space between implants
A minimum space of 3 mm should be
left between the margins of adjacent
implants in order to obtain a papilla.
Space between the contact point and the proximal bone
(Tarnow law)
A maximum space of 5 mm should be
left between the peak of the proximal
bone and the contact point of the
crown with the adjacent teeth.
The distance between the two red
points (in the photo) - the greater the distance, the smaller the
chances of obtaining a papilla (Tarnow OS).
The main aesthetic problem arises from
the amount of bone in the buccal region:
1. Crater formation around the tooth
According to the literature, the circumference
of the alveolus is a minimum of 1 .5 mm,
which means that 2-4 mm of bone on the
buccal surface of the implant are necessary
in order to prevent a buccal-marginal loss
of bone (Spray 00).
2. Rapid loss of bone in the
premaxillary region
• Proclination of the front teeth
• Prominent roots
• A very thin buccal plate
These anatomic conditions cause rapid and extensive bone loss
mainly in the anterior buccal region.
About one third of the buccal plate is resorbed in the first month
following the extraction.
Bone resorption begins in the first week following the extraction
and causes extensive thinning of the buccal plate during the first
three weeks (Carlsson 67).

Immediate
implantation in the
PM region with a
thin buccal plate

Significant buccal
resorption after 3
months

Immediate implantation
in the molar region with
a thick buccal plate

The buccal bone is
maintained after 3
months

Buccal bone resorption is affected by ridge anatomy (bone
thickness) and not by the placement of an implant (Araujo 06).

Conclusions:
• Critical bone mass (blood supply) is necessary in order to preserve the buccal plate and
achieve an esthetic result.
• It is not sufficient to leave about 1 mm of bone on the buccal side of the implant, but
rather a minimum of 2 mm of bone should be left.
• Even if the whole implant is within the bone coverage and the buccal plate is thin, bone
augmentation should be performed in order to thicken and maintain the buccal plate.
• The bone preservation is dependent mainly upon the surgeon.

Glass-Ionomer teeth fillings are
not inferior to silver amalgam ones
– a new study shows
New findings by researchers from the
SYSTEM Initiative based in Wits University’s
Department of Community Dentistry/
Faculty of Health Sciences indicate that
there is no evidence that high viscosity
glass-ionomers are inferior to silver
amalgams.
This has challenged the supremacy of
silver amalgams in dentistry and the widely
held believe that these amalgams make
better and more lasting tooth fillings than
high viscosity glass-ionomers.
The research was conducted by Dr Steffen
Mickenautsch and Professor Veerasamy
Yengopal, both from the Systematic Review
initiative for Evidence-based Minimum
Intervention
in
Dentistry
(SYSTEM
Initiative) in the Wits Faculty of Health.
Experts have for decades spoken out
against dentists’ choice to use of
glass-ionomers instead of silver amalgam or
composite resin materials for load bearing
posterior tooth restorations. But their
believes have been based on clinical

evidence that, when closely examined,
holds little scientific weight.
In an effort to appraise the current clinical
evidence regarding the merits of placing
glass-ionomers as tooth restorations, the
SYSTEM Initiative has conducted a
systematic review of randomised control
trials and a meta-epidemiological study.
The systematic review included a
literature search in 17 global and regional
databases, as well as databases for open
access journals and ‘grey’ literature. Besides
searching
the
global
databases
PubMed/Medline and the Cochrane Library,
the additional regional English databases
searched comprised of the scientific dental
literature from Africa, Europe, India and
North America, whilst regional non-English
databases comprised of the dental literature
from China and Latin-speaking American
countries.
In total, 38 trials were accepted as
evidence, comprising the investigation of
more than 10 000 placed tooth restorations.

Sirona announces material
partnership with GC
Japanese dental company GC becomes
Sirona's latest material partner. The
cooperation expands the global range of
top-quality CAD/CAM blocks for Sirona
systems offered by authorized manufacturers.
Bensheim/Salzburg, February 11, 2014. Sirona,
the technology leader in the dental industry, has
entered into an agreement with a new material
partner for the production of CAD/CAM blocks,
such as composites and other restorative
materials for CEREC and inLab. The Japanese
dental company GC Corporation complements
the group of selected partners that manufacture
high-performance materials for the milling and
grinding of CAD/CAM restorations: VITA
Zahnfabrik, Ivoclar Vivadent, Merz Dental,
DENTSPLY and 3M ESPE.
GC produces consumables, devices and
equipment for dental practices and
laboratories. The Tokyo-based company is
the global market leader for glass-ionomer
materials and also the world's largest
provider of expertise, advancements,

product quality and top customer service in
the fields of composites, ceramic layering
and adhesive systems.
"GC is a prestigious dental company that
focuses primarily on Japan and other Asian
markets. As these markets are becoming
increasingly important for our CAD/CAM
business, we are happy to have a material
partner in the region who meets our high
quality standards,” says Dr. Joachim Pfeiffer,
Vice President of CAD/CAM Systems at
Sirona in Bensheim. Sirona expects this
partnership to provide sales support in the
rapidly expanding Asian markets, while GC
profits through established access to Sirona
CAD/CAM users worldwide.
Japan is one of the largest growth markets
for CAD/CAM restorations and prostheses.
The country is already very well prepared
for the change to CAD/CAM technology.
Therefore, innovative dental technology
combined with high-quality materials is
increasingly in demand by local dentists. DT

Perfect complements: The CAD/CAM blocks of Sirona and selected partners are optimized to
meet the specific requirements of the MC XL milling centers.

The outcome shows that new generation,
high-viscosity glass-ionomers cannot be
regarded as inferior to amalgam, since no
overall statistically significant difference
was found in the clinical failure rate
between load bearing high viscosity
glass-ionomers and amalgam restorations
after follow-up periods ranging from one to
six years.
Mickenautsch says: “The results of
SYSTEM’s meta-epidemiological study show
that statements concerning glass-ionomers’
inferiority to amalgam and other types of
materials are based on incorrect statistical
comparison methods. Such methods include
the still common naïve-indirect comparison
of
restoration
failure
rates
from
uncontrolled clinical longitudinal studies.”
“Simply put, the traditional argument
against the use of glass-ionomers in modern
dentistry is based on the wrong assumption
that results from unrelated clinical trials
with differing clinical settings and patient
groups can be directly compared to one
another. Instead, statements concerning the
merits of clinical interventions should rest
on the direct comparison of competing
treatment options via randomised control
trials.”

High-viscosity glass-ionomer restorations
do not require provision of macro-retention
by high-speed drilling, thus they offer the
dental profession a more patient friendly
approach for placing tooth restorations.
Placing glass-ionomer restorations also
reduces the likelihood of a repeated
restoration cycle, because repair of failed
restorations does not require the removal of
remaining filling material from the tooth
cavity.
The new findings suggest that placing
high-viscosity glass-ionomer restorations
may offer an alternative to placing
restorations with silver amalgam in load
bearing posterior cavities of permanent
teeth. DT

Dentists to address global concern
over antimicrobial resistance at
IDEM Singapore
By: John Battersby, PR consultant for Bridges M&C,
commissioned to undertake PR for the IDEM
Singapore 2014 event

After the publication of alarming reports on
antimicrobial resistance both the EU
Commission and USA’s Food Drug
Administration
(FDA)
have
recently
announced stricter regulations aimed at
curbing the overuse of antimicrobials in the
hope of slowing the growing menace of
antimicrobial resistance (AMR).
In the light of these recent announcements
of the selection of Dr John Molinari and Prof
Ken Hargreaves to give talks on infection
management and alternatives to antibiotics at
IDEM Singapore 2014 is if not prescient then
certainly both apt and timely. IDEM Singapore
will be running from 4th to 6th April 2014.
In November 2013 the European
Commission
published
the
2013
Eurobarometer survey on antimicrobial
resistance (AMR) and the European Centre
for Disease Prevention and Control (ECDC)
released the latest data on antibiotic
resistance in the EU and European
Economic Area. Earlier in 2013 the US
Center for Disease Control (CDC) also
published a review of Antibiotic Resistance
Threats. All three reports were sobering
reading and, like previous reports from the
World Health Organisation (WHO) and the

Alliance for the Prudent Use of Antibiotics
(APUA), they highlighted the growing global
problem of antimicrobial resistance.
In a telephone interview, Dr Molinari, a
microbiologist, said, “I have been lecturing
doctors and dentists about the risks of
antimicrobial resistance for 20 years; it is a
growing public health concern around the
world.”
Dr Molinari, will be presenting a lecture
entitled, Infection Control – Yesterday, Today
and Tomorrow, at the IDEM Singapore 2014
scientific conference, sponsored by the
infection control specialist Scican. He believes
there are numerous issues involving
misperception and the misuse of infection
control procedures in all areas of healthcare
which are in conflict with the latest scientific
and clinical knowledge. He said, “Antimicrobial
resistance, the overuse and misuse of
antimicrobials is an important issue which I
will be addressing in my talk at IDEM.”
In an email interview Prof Hargreaves also
assured us, “I will certainly be covering this
topic in my upcoming lecture at IDEM
Singapore 2014.”
The professor, an advocate of local
antimicrobial therapies in endodontics to
reduce bacterial load as an alternative to
systemic antibiotics, went on to tell us, “There
is growing recognition of the impact of
antibiotic resistance as a health threat. In

2013, the US Center for Disease Control
(CDC) published an extensive review entitled
Antibiotic Resistance Threats in the United
States, 2013. This report, together with the
2013 Eurobarometer survey (ECDC) report,
provide compelling evidence for the prudent
clinician to understand this issue and to
provide
appropriate
treatment
for
odontogenic infections.”
Prof Hargreaves went on to illustrate the
problem with some alarming statistics. “The
numbers are striking. Every year in the US,
nearly two million people have infections with
antibiotic resistant bacteria and 23,000 of
these individuals die from their infections. It
has been estimated that up to 50 percent of
antibiotic prescriptions are made for patients
who do not have a medical indication for
these drugs.
These facts require a
re-evaluation of the use of antibiotics in
odontogenic infections.”
Prof Hargreaves believes clinicians should
consider all possible alternatives before
reaching for the prescription pad. “Local
antimicrobial
therapies
have
been
demonstrated in endodontic research to
dramatically reduce bacterial load, leading to
the recognition of the importance of this
alternative to systemic antibiotics. Further
research in this area is needed, but results to
date have led to an evidence-based guideline
for treating odontogenic infections.”
Prof Hargreaves will be covering this and
other related topics further in the series of
Master Class Lectures, sponsored by the
Singapore Dental Association at IDEM
Singapore 2014 in April.
This is not a new issue. Back in 1981, the
Alliance for the Prudent Use of Antibiotics
(APUA) was formed and in 1998 they helped
put together the Global Advisory on Antibiotic
Resistance Data (GAARD) project in an effort
to support and learn from the existing
surveillance infrastructure. GAARD brought
together the world’s largest surveillance
systems, integrating antimicrobial resistance
data from the various networks for special
studies designed to inform public health policy.
Several of the big pharmaceutical companies
agreed to contribute data from their on-going
surveillance systems as part of a unique
collaboration which saw for the first time the

private sector working with public sector
entities like the World Health Organization
(WHO), the World Health Organization
Collaborating Centre on Antimicrobial
Resistance, and the United States Center for
Disease Control.
Back in 2005, GAARD published its first
report, which included contributions from a
variety of other prominent systems tracking
resistance worldwide as well as the GAARD
group. While it unearthed important trends in
global drug resistance, the report also
exposed the paucity of coordinated local,
national, and global surveillance data and
called for more thorough and coordinated
efforts.
However, this is a call that has met only
limited response. It took the EU Commission
another eight years before they could
announce in 2013 that they had adopted new
legislation on the surveillance of AMR which
will ensure harmonised monitoring systems
in Europe, thus ensuring the comparability of
data between its Member States if not the rest
of the world.
While the EU and US have improved
monitoring and started to put new regulations
in place there has been little or no action in
the rest of the world, and especially among
developing nations. This leads to Africa, South
America, and parts of Asia becoming hotbeds
of AMR proliferation, as is the US, albeit for
different reasons. Just as there is no single
cause for the increase in AMR, there is no
single solution. In the US perhaps the biggest
contributing factor is the massive amount of
antibiotics used by the animal husbandry
industry; about 70 percent by weight of all the
antibiotics is used in the US.
Another major issue is that much of the
remaining 30 percent prescribed to humans
is unnecessary. In the developing world
self-medication, out-of-date or poorly stored
drugs, low dosages, uncompleted cycles, as
well as counterfeit drugs all fuel the AMR time
bomb. While dentistry may not yet be the
frontline in the AMR war, the growing threat
of AMR behoves all medical professionals,
regardless of their field or where in the world
they practice, to consider their own actions
and how they can do their own small part to
help control the problem. DT

Implants for Africa (IFA) and Ankylos
without Brian Pfohl is unimaginable. After
17 year’s dedication to Ankylos, ‘’Mr
Ankylos’’ has decided to call it a day. Brian
has been the mainstay and driving force
behind of the growth and expansion of IFA
and Ankylos since the start up by Dr Pat
Josephson and the late Dr Mark Otto. From
a little known implant company he
positioned IFA and Ankylos as a leading
brand in South Africa and Africa. Many
implantologists owe a great deal of their
knowledge and confidence to his calm
reassuring presence at the chair side and
over the phone. His presence at conferences
both locally and internationally was always
highly appreciated. Greatly respected
amongst his peers, both local and
international, he shared his vast knowledge
with everyone even when dealing with
doctors experiencing concerns with other
implant systems.

From IFA and all implant placing dentists
we remain indebted to his commitment and
loyalty. We wish him, Mr Ankylos and
Shirley a wonderful well deserved rest.
The good news is that Brian Pfohl will be
overseeing our International expansion and
remains available for your calls. IFA
remains committed to provide you the very
best of service across the country with our
dedicated sales representatives. DT
