Columbia University announces
India faces
breakthrough in tooth regeneration regulation

Stem-cell-infused scaffold holds potential for replacing dental implants
Daniel Zimmermann
DTI

NEW YORK, USA/LEIPZIG,
Germany: Dental implants could
soon become a secondary choice
for replacing natural teeth. According to new research from
the College of Dental Medicine at
Columbia University in New York,
three-dimensional scaffolds infused with stem cells yield an
anatomically correct tooth in as
soon as nine weeks once implanted. The new technique, developed by Columbia University
Prof. Jeremy Mao, has also demonstrated the potential to regenerate periodontal ligaments and
alveolar bone, which could pave
the way for re-growing natural
teeth that are able to integrate into
the surrounding tissue.
Previous research on tooth
regeneration has focused on cultivating stem cells directly on dental implants to improve osseointegration or outside the body, in
which case the tooth is grown
under laboratory conditions and
implanted once it has matured.

The Minister for Health and
Family Welfare in India, Ghulam Nabi Azad, has announced
legislation seeking to establish
a new government-run agency
to replace all existing regulatory
medical bodies in the country.
The National Council for
Human Resources in Health bill,
which follows a similar but
unsuccessful 2005 political campaign by former Health minister Ambumani Ramadoss, is also
intended to limit tenures of
appointed executive officials.

Mao’s technique, which has been
tested on animal models, moves
the cultivation process directly
into the socket where the tooth
can be grown orthotopically.
“A key consideration in tooth
regeneration is finding a costeffective approach that can translate into therapies for patients
who cannot afford or who aren’t
good candidates for dental implants,” Dr Mao told Dental Trib-

une Asia Pacific. “Our findings
represent the first report of regeneration of anatomically shaped
tooth-like structures in vivo.”

nal of Dental Research and will
be presented at this year’s International Association of Dental
Research congress in Barcelona.

Latest studies from Sweden
have demonstrated that bone
loss, one of the main reasons for
dental implant failure, remains
a challenge for dental clinicians.

Columbia has announced
that it has patient applications
on file regarding the engineered
tooth and is actively seeking partners to help commercialise the
technology through its technology transfer office, Columbia
Technology Ventures. DT

Europe defies
Sniff your dental
economic gloom pain away
Most major dental markets in
Europe achieved growth rates
above 3 per cent last year, a new
report by the Association of Dental Dealers in Europe in Switzerland has revealed. France had
the highest growth rates in 2009
with 20 per cent, followed by the
United Kingdom (7,4 per cent)
and Germany (3,2 per cent). DT

US clinicians have found that
intranasal drugs travel through
the main nerve in the face and
collect in high concentrations in
the teeth, jaw, and structures of
the mouth. The discovery could
lead to a more effective and targeted method for treating dental
pain, trigeminal neuralgia and
other conditions. DT

The Filipino government has
been called on to include public
school dentists and assistants in
the next update of the Salary
Standardization Law III in July.
The legislation, signed by President Gloria Macapagal-Arroyo
last year, aims to standardise basic salaries, allowances, benefits
and incentives for 1.5 million
government employees. It also
secures the annual increase of
public salaries until 2013.
Currently, more than 700 public school dentists and assistants
work in the Philippines, treating
a population of 21 million, according to the Department of
Education Dentists’ Association.
The Association says that because
dental workers have to undergo
regular continuing education
programmes and purchase necessary dental equipment such
a demand can be justified. DT

Patients in Malaysia go on record
HONG KONG/LEIPZIG, Germany: Malaysia Healthcare, a
medical tourism facilitator in
Malaysia, is offering a medical
record storage device to
foreign medical tourists
and domestic patients who
wish to go abroad for treatment. The individual Personal Health Electronic
Record (iPHER) USB device,
which is produced by a US
company based in Florida, is
able to carry basic patient
data, such as blood type, allergies and dental records. It
allows medical professionals
to access a patient’s medical
history quickly.
Physicians and dentists in
Malaysia and most Asian countries are currently not required
to store their patient’s medical
data in digital format. Malaysia

Healthcare is the first provider to
offer such a service to patients in
Malaysia. At a medical tourism
congress in Kuala Lumpur last

month, CEO Suresh Ponnudurai
told reporters that his company
is offering the iPHER device
because of the low Internet penetration rate in many parts of
South East Asia. A self-contained

device like the iPHER can make
patient records accessible in
places without Internet connectivity, he added.
Digital storage of medical
records is increasingly becoming big business in the
health care sector as broadband Internet becomes available in more parts of the
world. Computing companies
like Microsoft and Google
already offer web-based platforms that can store and exchange medical records and
data. Data protection specialists,
however, have warned against
the massive outsourcing of medical record transcription and
storage, which has the potential
to violate patient–physician confidentiality by allowing unauthorised persons access to critical
patient data. DT

Japanese students lack interest in
private dental schools
From news reports

TOKYO, Japan: Enrolment in
private dental schools in Japan
has decreased again during
spring term, a survey by the
Japanese Association of Private
Dental Schools has found. Figures released by the organisation last month show that almost
70 per cent of the schools missed
their intake quota. The total
number of students who wrote
entrance examinations for private dental colleges was 4,318,
a sharp fall from over 10,000 in
2006.
The institution that suffered
most from the lack of new stu-

dents was Ohu University in
Koriyama, Fukushima Prefecture, which only had 32 new students enrolled for a quota of 96,
according to the survey. Matsumoto Dental University in
Shiojiri, Nagano Prefecture, had
35 students enrolled compared
with its quota of 80, while the
School of Dentistry at the Health
Sciences University of Hokkaido
in Tobetsucho, Hokkaido, enrolled only half of its 96-student
quota.
Private dental schools in
Japan have been struggling to
attract a sufficient number of
students in recent years because
the dental workforce in the coun-

try has increased significantly in
the last 20 years, despite stable
total dental care costs. In 2006,
Japan had 96,000 dentists compared with only 71,000 in 1990,
according to figures from the
Ministry of International Affairs
and Communications.
Dental experts said the drop
in the number of private dental
institution applicants suggests
that fewer young people have
a positive image of dentistry as
a lucrative and desirable profession. They pointed out that if the
trend continues, private dental
colleges and schools will not be
able to select students with sufficient academic quality. DT

AAAD elects Japanese dentist for president
Claudia Salwiczek
DTI

HONG KONG/LEIPZIG, Germany: Dr Hisashi Hisamitsu from
Japan was recently appointed
President of the Asian Academy of
Aesthetic Dentistry (AAAD). The
62-year-old dentist from Kawasaki
City succeeds Dr Sim Tang Eng
from Malaysia, who has served
as President for the last two years.
Dr Hisamitsu is currently Chairman of the Department of Clinical
Cariology and Endodontology at
Showa University School of Dentistry in Japan.

Kuala Lumpur in May. In addition,
Dr Wang Guang Hu from China
has been appointed PresidentElect. He will be elected President
at the next AAAD meeting, which
will be held in 2012 in Japan. The
AAAD General Assembly also
appointed Dr Takashi Nakamura
from Japan as General Secretary.
AAAD meetings take place
every two years. This year’s gather-

ing, with the theme High Definition
Aesthetic Dentistry, drew 349 delegates to Kuala Lumpur. It was organised jointly with the Malaysian
Association of Aesthetic Dentistry
and offered well-known speakers
in the field including Drs Mauro
Fradeani (Italy), Didier Dietschi
(Switzerland), and Bruce Matis and
Rhys Spoor (USA), who also conducted two hands-on workshops at
the University of Malaysia.

The AAAD was originally
founded in 1990 at the Prince Philip
Dental Hospital in Hong Kong.
Since then, the Academy has grown
annually and the number of member countries has increased from
three to twelve, including China,
Hong Kong, India, Indonesia,
Malaysia, Nepal, the Philippines,
Taiwan and Thailand. It is also a
founding member of International
Federation of Esthetic Dentistry. DT

Sea animals
could
cement
cavities
HONG KONG/LEIPZIG, Germany: Students at the Hwa Chong
Institution in Singapore are currently investigating the adhesive
properties of barnacles for use in
dentistry. Their research, which
received a Gold Award at this
year’s Singapore Science and Engineering Fair, may offer a new
means of attaching dental braces
or cementing cavities in teeth.
Barnacles are marine invertebrates that live in shallow or tidal
waters. They attach themselves
permanently to hard substrate
like rocks or ships with the help of
a protein-based adhesive, called
barnacle cement. Shipping companies spend millions every year
to remove massive accumulations
of these animals, which can slow
down ships and increase fuel consumption.

“IT’S AN
EASY
DECISION.”
Shigeo Kataoka, Dental Technician, Japan.

Worldwide, more than 1,220
barnacle species have been identified.
The students explored biocompatibility, speed of polymerisation and acid resistance in the
cement secreted by a barnacle
species called Amphibalanus
amphitrite. They found that the
cement is water insoluble and has
strong mechanical properties,
but is safe for humans to use in
the mouth. The researchers observed, however, that the cement
lacks resistance to long-term exposure to strongly acidic conditions. Its adhesiveness was compromised by acidic substances,
such as orange juice and soda,
they said.
The team, which is supported
by the National University of
Singapore, is now working with a
new experimental design that can
better simulate oral conditions
in humans. If successful, the outcome could also be beneficial for
other medical applications, such
as joining bones in surgery. DT

If durable all-ceramic crowns are required, the
decision is easy: IPS e.max lithium disilicate. With
this material, you can fabricate robust crowns
quickly and efficiently. Given the material’s high
esthetics, veneering in the posterior region is
unnecessary.

DENTAL TRIBUNE Asia Pacific Edition

Dear
reader,

Transparent
dentistry, the
need of the
hour in India

“Finally, our rotten
teeth are good for
something.”

Daniel Zimmermann
DTI

Dr Ashok Dhoble
Hon Secretary General
Indian Dental Association

By the time you are finally
holding this edition of DT Asia
Pacific in your hands, the first
matches of the FIFA 2010 World
Cup will have already been
played. For four weeks in June
and July, the eyes and minds of
billions of people around the
world will turn to South Africa in
hope that their team will win the
world’s most coveted trophy in
sports.

The Indian government recently announced a single regulatory body for professional
education in the country that
will oversee professions related
to medicine, dentistry, pharmacy, public health and allied
health sciences. Its function
will be to coordinate the entire
gamut of medical and health
education, which hitherto was
done by independent bodies,
such as the Dental Council of
India (DCI).

Unfortunately, the word hope
cannot be applied to the host
country itself. South Africa,
though still one of the Black Continent’s most advanced nations,
remains a deeply divided and
troubled nation with problems
that even the best organised
World Cup will not be able to
erase from the political and social landscape any time soon.
The lack of oral health care is
just one of the minor problems in
the country.
According to the latest figures
from UNAIDS, almost 6 million
or 12 per cent of the South African
population is living with HIV/
Aids. The mortality rate linked to
the disease has doubled from
slightly over 300,000 in 1997 to
over 600,000 in 2006. Half of these
deaths are within the most productive age groups, which significantly affects the country’s economic output and development.
To make things worse, South
Africa has increasing numbers of
tuberculoses infections (TB).
The government in Pretoria
has announced a National Strategic Plan to fight the spread of
HIV/Aids and TB and to increase
testing as well as HIV/Aids
awareness amongst the population until 2011. For the success of
this campaign, the country will
also need support from outside
its borders. The tournament can
help raise awareness but only if
the world is willing to not only
watch for the winning goal, but
also look beyond the pitch and at
the millions of people suffering
in the townships of Durban, Cape
Town and Johannesburg.
We will try to keep our eyes
open. DT

Oral health and care in South Africa
Prof Sudeshni
Naidoo
South Africa

Despite great achievements
in the oral health of populations globally, problems remain
in many communities around
the world. The decline of oral
diseases in industrial countries
means that the burden of
oral diseases can be prevented
and controlled with fairly simple interventions. Advances
in knowledge and technology
and preventive interventions in

concern, not only as dental
caries and periodontal disease
are preventable and treatable
conditions, but also because of
the increased risk regarding
blood-borne infections such as
HIV/Aids and hepatitis in a region where these conditions are
rife. A shift from the endemic
curative philosophy to an approach to oral health care that is
more promotive and integrated,
both amongst the public and
health-care professionals, is
urgently required.
In general, there is a low
utilisation of oral-health services and this may be due to

sources. This, together with insufficient emphasis on primary
prevention or oral diseases,
poses a considerable challenge.
Opportunities exist to expand
oral disease prevention and
health promotion knowledge
and practices amongst the public through community programmes and in health settings.
The major challenges for
the future will be to translate
knowledge and experiences of
disease prevention into proactive programmes. Social,
economic and cultural factors,
as well as the changing population demographics, affect the

“Optimal intervention in relation to oral
disease is not universally available.”
health can virtually eliminate
the pain, suffering and loss of
quality of life that accompany
oral diseases. In South Africa,
the availability of such advances is not universal. The distribution and severity of oral
disease varies in different parts
of the country.
A recent survey found that
almost a fifth of the South
African population reported
oral-health problems and this
relatively high level of perceived oral-health problems
implies that oral health should
be of greater priority. Furthermore, levels of edentulousness
are unacceptably high and of

factors of accessibility, affordability and the type of services
provided. Difficulties pertain to:
(i) the structure and management of oral-health services in
most of the provinces; (ii) the
dentist-driven public oralhealth services; (iii) the palliative and demand-driven nature
of the services; (iv) inequities
in oral health care in the provinces; and importantly (v) the
mainly urban location of oral
health-care services.
In South Africa, optimal intervention in relation to oral
disease is not universally available or affordable because of
escalating costs and limited re-

delivery of oral-health services.
Reducing disparities requires
far-reaching, wide-ranging approaches that target at-risk
populations regarding specific
oral diseases, and involves
improving access to existing
care. DT

Management of the independent bodies has come under
public criticism and judicial
censure. Evidently, there is an
urgent need for innovation in
health education. Corruption
charges have been laid, but
these are allegations that need
to be proved. The current system lacks transparency in all
matters, and in dealing with
public more transparency is required. Corruption, whatever
its extent, needs to be dealt with
severely and heavy punishment, apart from dismissal,
should be meted out. This calls
perhaps for a change in the
legal system.
Whatever the regulatory
body, it should be managed by
experts of high calibre and integrity, independent of government control, with the good of
the country and community in
mind. Whether a single body
would be able to address the
challenges of the various professions remains to be seen, but
this can only be determined
through investigation and experimentation.
The new regulatory body,
whenever it is established, is
not expected to effect miracles.
But if it is staffed by those with
integrity, honesty and a commitment to public health, it will
prove beneficial to the community. DT

“Automated external defibrillators should
be present in every health-care environment”
An interview with Dr Morton Rosenberg, USA, about medical emergencies in the dental practice
Rather than use the term
outdated, it is important to
understand that preparing for
a medical emergency is an
evolving standard of care. One
of the major changes has
been the availability and use

of automated external defibrillators (AED), which should be
present in every health-care
environment. The American
Heart Association 2005 guidelines have placed early defibrillation as an integral part of

the Basic Life Support (BLS)
‘chain of survival’ for the treatment of cardiac arrest. The
immediate availability of an
AED has been demonstrated
to increase the success of resuscitation.

In the US, some states
(Florida, Washington, Illinois)
have mandated the presence
of an AED in dental offices.

Dr Morton Rosenberg, USA

Dentists must always be prepared to manage medical
emergencies, which are most
likely to occur during and
after local anaesthesia. Although studies have found
that most of these complications are mild, around 10 per
cent of all incidences should
be considered serious. Recently, an updated list of
emergency medications and
equipment for dental providers, including an emergency
preparedness checklist, was
developed by Dr Morton
Rosenberg of Tufts University
School of Dental Medicine
in the United States. Dental

list and the importance of the

Dental Tribune Asia Pacific:
Medical emergencies in dental offices are rare but likely
to happen at some point during a dentist’s career. Have
the types of medical emergencies changed in the last
couple of years?
Dr Morton Rosenberg: Although it is very difficult to
gather data on this topic, the
perception of most experts is
that the incidence of medical
emergencies is increasing in
the dental office. The types of
medical emergencies are still
centred on the cardiovascular
and respiratory systems.

an increasing problem in
clinical settings. What medications do you consider
problematic in this respect?
Without a doubt, antibiotics
are always at the top of the list
of medications that are administered to many patients in
the course of dental treatment
and which have the potential
of being a trigger for a host of
allergic reactions. It is also important for the dentist to know
that an increasing number of
patients have allergic reactions
to latex.
What types of equipment
do you recommend?
The equipment that should
be readily available includes
a portable E cylinder of oxygen,
oral pharyngeal airways, as
well as devices for the administration of supplemental
oxygen, including a bag-valvemask. I further recommend
Magill forceps, an AED, a
stethoscope, a sphygmomanometer and a wall clock with
a second hand.
Proper risk assessment
and documentation could
prevent many of these medical emergencies. What are
the first indications that
identify a high-risk patient?
It is only through a detailed
medical history, a thorough
review of the positive responses by the dentist, focused
physical examination and vital
signs, and appropriate consultations that patients at high
risk for medical issues during
dental procedures can be identified.
What are the best strategies for prevention?
The hallmarks of a wellprepared office are meticulous preoperative assessment,
appropriate and basic emergency equipment, and dentists
and staff current in BLS-HCP.
Constant review and, most importantly, unannounced drills
will make the office immediately able to recognise, call
for help, and address the immediate needs of the dental
patient with a medical emergency.
Thank you very much for
the interview. DT

Help for Haitian dentists still
lacking, HDA president says
Javier M. de Pisón
DT Latin America

PUERTO VALLARTA, Mexico:
The President of the Haiti Dental
Association (HDA), Dr Samuel
Prophete, told Dental Tribune
Latin America that people are
working again and that his country has begun functioning to
some extent, but that large tent
cities remain, posing great sanitation and security problems.
Dr Prophete participated in
the conference held as part of
the A Smile for Haiti initiative of
the Ibero-Latin American Dental
Federation thanks to a grant from
the International Congress of
Oral Implantologists and specifically to the efforts of its Latin
American Director, Dr Alvaro
Ordóñez from Miami.

shipped to Haiti by Henry Schein,
Dr Prophete said that more immediate help could be obtained
by purchasing equipment or materials from Haitian dental depots for Haitian dentists.
Dr Prophete pointed out that
this is an important way for den-

tists to gain supplies to tend to
their patients’ needs and it keeps
the economy moving forward for
Haitians. There is a real concern
that dentists who cannot work
in Haiti will migrate, leaving
a country with already very low
rates of dental services in an even
worse situation. DT

Two months after DT Latin
America brought Dr Prophete to
the Chicago Midwinter Meeting
for talks with the Chicago Dental
Society and American Dental
Association officials on ways to
help Haitian dentists, little aid
has trickled down to the Haitian
dental community. Asked about
the reaction of his colleagues to
the campaign for Haitian dentists,
he said that after the trip to Chicago
he called a meeting to explain
the commitments to help made by
American dental organisations.
“I told them, ‘I cross my fingers and
wait for the resources to come’, but
for the time being I’m selling hope
to them.”
Dr Prophete said his association will use the initial aid
received to help the 12 dentists
most affected by the earthquake,
the ones who lost everything, of
the 35 dentists in need of help.
“Haitian dentists have partnered to work together with the
ones who have lost their practices,” Dr Prophete said. “This
has allowed dentists to survive,
but they are still waiting” for aid
from several dental organisations and other sources in the
dental industry.
Looters ransacked dental offices after the earthquake, leaving many professionals without
tools or materials. While institutions such as New York University College of Dentistry have donated dental chairs that are being

“Dentistry nowadays has become a field of
constant technological challenge”
An interview with Guido Bartels, Sales Fellas, Germany
The responsibilities of dental
technicians in the future will also
differ significantly from the tasks
they perform today. The profession and its requirements will
change drastically. Dental technicians will become ‘refiners’, responsible only for partial tasks in
the production process. I do not
foresee any role for the all-in-one
dental technician.

Guido Bartels

Latest reports from the industry
suggest that dental manufactures were affected little by
the global recession. However,
changing productions methods
and customer behaviour have recently begun to change the market. Dental Tribune Asia Pacific
spoke with industry veteran and
Asia consultant Guido Bartels,
Germany, about the state of the
industry and new developments
that are going to shape its future.
Dental Tribune Asia Pacific:
Mr Bartels, recent market surveys show that the dental industry appears to have defied the
global recession. Have we finally
overcome the crisis?
Guido Bartels: In the past, this
industry has been one of the industrial sectors first affected by changing consumer behaviour and decreasing investments. At the same
time, the industry has also been the
first to recover from a crisis. However, we must not forget that even in
economically challenging times,
the dental industry in Germany,
for example, is strongly supported
by the public-health insurance
system. This will definitely change
in the future. Owing to the demographic shift in our societies, existing social security systems will be
altered, leaving individuals with
greater responsibility regarding
their health. This development will
possibly influence the outcome of
future crises.
What conclusion should the
industry draw from the crisis?
Change always entails the
recognition of new opportunities.
The industry has visibly been on
the road to change in recent years.
At first, this change happened gradually, mainly because precious
metals manufacturers tried their
utmost to keep their dominant
position in the market against alternative ceramic materials. There
are a number of new materials
available now, especially ceramics,
that can make the production of
dental prosthetics more cost-effective in the long run. Similar to other
industries, dentistry nowadays has
become a field of constant technological challenge in implementing
innovative thinking for technically
advanced solutions. Considered
product concepts and cost reduc-

tion are only one side of the coin.
Paradigms concerning consumer
loyalty and service have to be revised, as the way we communicate
and gather information in our
society has changed dramatically
through the Internet.
Mergers and acquisitions
have become part of daily business in dentistry. Are we experiencing market concentration?
In this regard, while the dental
industry is a latecomer, it will not be
able to escape this global market
trend. Once again, the main reason
for this is the constant availability
of goods and services through the
Internet. The resulting increase in
international economic competition
has become a driving factor behind
thought patterns not only in production processes, but also in consumer
expectations. This trend cannot
be halted and will be further driven
by concentrated development of
promising business concepts.
Should companies focus on
their core competencies in the
current situation or invest in
additional, rather unfamiliar
product segments?
Business concepts focusing on
core competencies will always be
successful in the long run. Other
competences that are controllable
through good management, however, can be bought in through
business acquisitions or mergers.
The latest examples from the industry demonstrate that companies with all-in-one solutions can
be successful and that the market
is open to their offerings.
Significant investments are
flowing into the digital manufacturing of dentures. Is this
a novel market potential, and
will traditional production processes be replaced?
While other industries have already undergone similar developments, we are experiencing only
the beginning of a new development chain. Centralised and lowcost production will have a significant effect on dental industries in
the long run. Apart from digital imaging and CAD/CAM technologies
that are already available, there
will be a trend to medium-sized and
large production centres that will
replace the laboratory next door.

What other developments do
you think will shape the market?
It is increasingly obvious that
our health care systems are drastically changing and starting to
compete not only for patients,
but also for health professionals.
Following this trend, insurance
companies will likely develop new
concepts that focus on loyalty towards patients, health professionals and medical centres. In dentistry, I consider that competitive
edge and lower costs for dental
prostheses will be decisive factors.

Many dental companies have
announced large investments in
the Asian market. Is the market
potential really that high?
In terms of market potential,
India and China indeed offer enormous business opportunities.

Therefore, you can expect some
prominent acquisitions of international brands and companies by
Chinese manufacturers. However,
when you consider the market potential in Asia you have to remember that it is often difficult to gain

“Business concepts focusing on
core competencies will always
be successful in the long run.”
Approximately 250 million Chinese,
residing primarily in and around
large cities like Shanghai, already
have an average monthly salary
of €6,000 at their disposal and the
Chinese government is working on
further improving the prosperity of
their population in accordance with
its five-year plan. The country is also
striving to establish some of its own
commercial brands on the global
market within the next five years.

access to these markets because of
differences in culture and consumer behaviour. Often, importing
goods there entails costly registration processes, which means that
small and medium-sized companies
are reluctant to enter these markets.
Thank you very much for the
interview. DT

The social revolution
Networking sites offer a great means
of promoting your dental practice
Mhari Coxon
UK

Imagine if you would, a time
when there were only three
analogue television channels
—closing before midnight, no
mobile phones and no home
computers. The World Wide
Web was unheard of. Letters
had to be posted. That was my
childhood. If you had told me
I would be on Facebook this
time last year, I would have
laughed, told you I didn’t
have enough time and refused
to consider it.
I only learnt to use predictive
text last year, thanks to the
patience of a 14-year-old patient—though I still haven’t come
to grips with shorthand text
much to the amusement of my
friends. They say I send books
not texts.
AD

Thankfully, our wonderful
administrator (also my husband) set up a profile for me as
the company and a page for us
as CPDforDCP Ltd on Facebook
last year. Six months on, we
have more than 1,900 friends
and it has allowed us to interact
with dental professionals all
over the country and produce
courses tailored to their needs.
Some of our courses are never
advertised off Facebook, as they
are filled up directly from there.
Listening to our friends in the
business and being part of
groups has given us an insight
into which direction we should
be heading in our 2011 planning—all of this from the comfort of my own living room with
a cup of tea in hand.
Facebook offers information
and answers: there is a lot of
instant information at your fin-

gertips and if you don’t know
where to look, you can ask one of
the many groups, such as Dental
Nurse Network or UK Dental
Hygienists. On Facebook, someone invariably knows the answer or connects you to someone or some business that does.
Many forms of CPD (free and
otherwise) are recommended
and links posted to these are
available to everyone.
I have had conversations
with oral surgeons from Israel,
special needs’ dentists from
Germany and found many great
articles through the groups’
suggestions. On the site, business coaches offer advice, and
other businesses support each
other. Perhaps I am starting to
make it sound like a commune,
but that is because that is what it
reminds me of. There is a social
side to this too, providing an

environment for friendly debate
and discussion, and an occasional moan too. There are
many fun groups, such as the
one that managed to get Rage
Against the Machine to 2009
Christmas number one, demonstrating the power of this site.

Not just the little people
The British Dental Health
Foundation said the following
in a recent press release: “Since
introducing the online strategy
a little over two months ago,
the British Dental Health Foundation has seen traffic to its
website increase by more than
a staggering 35 per cent.”

directly and much business is
conducted through Facebook
and other social networking.
There are many forms of
social networking that work in
a way similar to Facebook:
Twitter (am too scared of this
site, might like it too much and
start boring you all with my food
choices and colour of socks—
less is more), YouTube (watch
out as we are on our way!),
my space and many others.
There are even companies that
will manage these pages for
you and your company so you
can access your clients in as
many different ways as possi-

“On Facebook, someone
invariably knows the answer or
connects you to someone or
some business that does.”
The Foundation posts a variety of oral-health advice, dental
research and industry-based
news.

ble—text, tweeting, Facebook,
e-mail—providing convenience
and a form of communication
suited to your clients’ needs.

Dr Nigel Carter, Chief Executive of the British Dental
Health Foundation, is astonished by the speed of its success:
“When we first stepped into
social networking we hoped
that it would bring us closer to
the public as another means of
getting across good oral health
messages. Our plan was long
term, to grow a steady following
and slowly increase traffic to
the website but its growth has
already surpassed all that
we imagined. We trebled our
three-month target within the
first three weeks and these figures have continued to rise.”

So come on, join the social
revolution in some form,
whether to meet colleagues and
peers, connect with your existing clients or find new clients,
find information, or just to see
what all the fuss is about.

Facebook and, ever at the forefront, find Dental Tribune on

“We are making new relationships with people of all
ages, from all backgrounds on

and interact in a positive way to
develop new business. Companies can talk to their patients

Certain patients, however, do not find it effective.
New desensitizing toothpastes with arginine and

“Dental caries is…not easily prevented
or treated in the most susceptible children”
An interview with Prof. Jill Fernandez and Drs Neal Herman and Lily Lim, New York University, USA
with special needs, and children
with HIV/Aids infection.
You might be referring to the
National Health and Nutrition
Examination Survey that demonstrated an increase in dental
caries from 24 per cent to 28 per
cent in the two to five-year-old
group. The reasons for this are
presently unclear, but this increase has reignited efforts in
the US to improve access to care
for this age group and motivate
more dentists to treat very young
children in our population.
Prof. Jill Fernandez

In July, paediatric dentistry
specialists will gather in Pasay
City, the Philippines, for the
7th biennial congress of the
Pediatric Dentistry Association
of Asia. Daniel Zimmermann
spoke with presenters Prof.
Jill Fernandez and Drs Neal
Herman and Lily Kim from the
New York University College
of Dentistry about their participation and recent developments in the field.
Daniel Zimmermann: The
US congress recently approved
a new proposal for health
care reform. In your opinion,
what impact will this policy
change have on children’s dental care?
Prof. Jill Fernandez: It is still
too early to know what the final
health reform bill will entail exactly, but as of now it does include
mandatory paediatric dental
care that requires dental coverage be offered as part of any
essential benefits package for
children under the age of 21. The
new law will enable stand-alone
dental plans to offer dental benefits as part of any health insurance exchange and/or subcontract with medical plans. The impact of this on the public and the
profession could be monumental
—the message is to begin oralhealth preventive interventions
early in the lives of children, and
that oral health is an integral part
of overall health.

Early Childhood Caries
(ECC) has increased not only
in the US, but also worldwide.
Should this area be considered
a new priority in paediatric
dentistry?
Prof. Jill Fernandez: ECC,
and efforts in the intervention
and treatment of early dental
decay, has always been a major
priority. In order to combat the
current national epidemic of
ECC in young children effectively, a more comprehensive,
collaborative approach to the
education of parents by all newborn and paediatric health-care
providers, such as nurses, paediatric and general dentists, dental hygienists, paediatricians,
paediatric nurse practitioners,
obstetricians and gynaecologists, is essential.
The American Academy of
Pediatrics (AAP) began a collaborative effort with paediatric
dentists to address the issue of
ECC. The AAP has made strides
in developing educational programmes for paediatricians and
family physicians to identify atrisk children and refer them for
dental treatment.
However, for many children
access to dental care remains
a problem and the number with
dental caries seems to be growing. Many parents do not have
dental insurance; thus, they postpone dental treatments until the
problem is so advanced that it

ECC a transmissible disease.
What is your opinion on the
latest research and how will it
affect the way children should
be treated?
Dr Neal Herman: The nursing bottle is only one of many
confounding factors in ECC.

preserve a primary tooth rather
than extract it (whenever possible). The goals of treatment for
primary teeth are not much different to that for permanent
teeth; in both cases, diseased
portions of the dental pulp are
removed in an effort to preserve

a lifetime, and gutta-percha fits
that bill. The ideal root-canal filling material for primary teeth
should resorb at a similar rate
to the primary root in order to
permit normal eruption of the
successor tooth; not be harmful
to the underlying tissues or to

What we conclude from the latest
research is that dental caries is
highly complex and perplexing,
not easily prevented or treated
in the most susceptible children.
It is believed these days that there
are nutritional, behavioural, immunological and bacterial factors that must be considered in
order to understand and prevent
dental caries.
The surgical approach to
ECC—the ‘drill and fill’ solution
of placing restorations in teeth as
they become cavitated—has long
been proven futile and often
counter-productive. Therapeutic interventions, particularly
utilising fluoride varnish, have
shown promise in preventing,
arresting and reversing carious
lesions. Much more work must

the hard structure of the tooth for
functional or cosmetic purposes.
Anatomical and physiological
differences between primary and
permanent teeth make a difference to the principle of root-canal
treatment. A permanent tooth
requires an inert, solid, nonresorbable material that can last

the permanent tooth germ; fill
the root canals easily; adhere to
the walls and not shrink; be easily
removed, if necessary; be radiopaque; be antiseptic; and not
cause discoloration of the tooth.
There is currently no material
that meets all these criteria, but

“ECC is a bacterial disease that requires
more than just filling up the holes.”
The oral health of children
in the US is poor and caries
figures are at an all-time high.
What are the reasons for this?
Prof. Jill Fernandez: Actually, the oral health of children in
the US has improved significantly over the past few decades,
when you look at a national sample across all age groups. Today,
most American children have excellent oral health, but a significant subset suffers from a high
level of oral disease. The most
advanced disease is found primarily amongst children living
in poverty, some racial/ethnic
minority populations, children

can no longer be ignored. It is
unfortunate that even parents
who have third-party coverage
for dental care (Medicaid, Child
Health Plus) and are from lower
socioeconomic backgrounds often fail to seek dental care as part
of general health-care services.
As a result, pre-school children
with Medicaid may still have untreated decayed teeth.
Frequent bottle-feeding at
night has been identified as
a driving factor for ECC. Other
studies have found a microbiological connection between
mother and child, labelling

be done to document its success,
but at least this ‘medical model’
has begun to address the fact that
ECC is a bacterial disease that
requires more than just filling
up the holes that are merely its
symptoms.
Root-canal treatments in
primary teeth are also becoming more common. Does the
treatment differ in any way
from that of permanent teeth?
Dr Lily Lim: We’re not sure
that pulp therapy is on the increase but if it is, it’s probably
because more parents (and
dentists) realise it’s best to try to

the filling materials most commonly used for primary pulp
canals are non-reinforced zincoxide-eugenol paste, iodoformbased paste (KRI), and iodoform
and calcium hydroxide (Vitapex).
A study in the Netherlands
has found that prevention
involving the counselling of
parents on caries-promoting
feeding behaviour is often ineffective in the long term. Is

there a lack of quality intervention strategies?
Dr Neal Herman: If we (or
the WHO) could answer this
question, we’d have found the
key to unlocking the mystery of
improving or enhancing human
motivation. It is probably true
that without continual and periodic follow-up, counselling will
wear off even amongst highly
motivated individuals. We think
the key lies with education that
begins early and promotes a
sound nutritional and sustain-

able oral-hygiene model for parent and child alike. As you might
imagine, this is a task not well
suited to the traditional dentalcare delivery model, and will
require some serious paradigm
changes to permit effective implementation.
What preventative measures do you recommend based
on your clinical experience in
New York?
Dr Neal Herman: Preventive
measures and conservative ther-

apies that confront the cause of
the disease, rather than treat the
symptoms, are the most effective
and work the best. Fluoride varnish has proven to be a godsend,
although most of the evidence to
date is empirical and anecdotal.
Good long-term longitudinal
studies are needed to prove conclusively what we already know
as clinicians—an intensive regimen of fluoride varnish, along
with adjunctive measures, can
control and often reverse dental
decay, as well as prevent it.

Dr Lily Lim: Starting in infancy, children at-risk for dental
decay should be receiving twiceyearly applications of fluoride
varnish, whether by a dentist
or dental professional, or as part
of their well-baby care from
their paediatricians. More than
40 states in the US have implemented such programmes, and
the outcomes are impressive—
as much as 40 per cent fewer
children with early signs of ECC.

AD

How many people would like
their teeth to look more beautiful? And how many of them
avoid dental treatment merely
because they fear that they
have to sacrifice healthy tooth
structure to achieve an aes-

thetic improvement? These
questions cannot be answered,
of course. However, dentists
who have found it difficult to
convince their patients of the
advantages of corrective dental treatment because they are
scared of having their teeth cut
can now offer a conservative
alternative in the form of minimally invasive restorations.

Misaligned teeth and gaps
between teeth are unpleasant.
Nobody likes to see large gaps
between their teeth, particularly
not in the anterior region. These
were exactly the concerns of this
17-year-old female patient, who
presented to our practice with
a wish to improve the aesthetics
of her anterior teeth (Fig. 1). At
the same time, she insisted on
preserving the healthy tooth
structure of her anterior teeth,
and required relatively inexpensive treatment. Mandibular teeth
#35 and 44 were congenitally
absent. In addition, the patient
lost tooth #36 due to endodontic
complications.
First, the patient underwent
long-term orthodontic treatment to close the existing gaps.
The missing teeth #35 and 36
were replaced with implants,
onto which temporary restorations were placed. In order to increase their stability, brackets
were bonded to these restorations and to the entire natural
dentition.

Precise planning,
accurate outcome
The patient’s aesthetic appearance was also impaired
by an excessive display of gum
tissue (gummy smile). When
she smiled, the asymmetrical
contours of her gingival tissues
became visible. The high dynamics and slanted contour of
her lips could not be influenced
therapeutically (Fig. 2). Moreover, the teeth appeared barrelshaped.
Correcting such a situation
is unforgiving of mistakes. The
treatment has to be planned and
performed with absolute accuracy. For this purpose, gum contouring was carried out upon
completion of the orthodontic
treatment and successful stabilisation of the dentition. Excess
gum was trimmed away with
a soft-tissue laser and the gingival contours of the two central
incisors were harmonised with
each other (Fig. 3).
The advantage of laser contouring is that the laser naturally seals the wounds and treatment can be continued soon
after contouring. The mirror
image shows the situation after
one week with a palatal view of
the anterior teeth (Fig. 4).

Thin and yet stable
At the next stage, the dental
technician in charge determined
the final tooth shade with the
help of a shade guide and shade
samples, taking into account the
initial tooth shade, which plays
a major role particularly in very
thin translucent restorations.
An impression was taken to create a model with detachable segments. A wax-up was designed
on the model to plan and determine the position of the incisal
edges. In the process, particular
care was taken to extend the
incisal edges only minimally.
Otherwise, the completed restoration in situ would have
given an optical impression of
being too long.
Please note that the dental
technician should apply no
more than two thin coatings of
die spacer to the dies. The
spacer should be applied only up
to 1 mm from the preparation
margin in order to avoid hollow
restoration margins in the oral
cavity.
Thin veneers, as presented in
this case, are fabricated by creating a fully anatomical wax-up,
which is pressed and then characterised with stains. IPS e.max
Press (Ivoclar Vivadent) is ideally
suited for this purpose. This material is composed of lithium
disilicate glass-ceramic and is
2.5 to 3 times stronger than other
glass-ceramic materials. Having
a flexural strength of almost
400 MPa, IPS e.max Press offers
exceptional stability (Fig. 5).
These characteristics convey
sufficient strength to veneers,
inlays, crowns and similar restorations to withstand comparatively high loads. Furthermore,
restorations made of IPS e.max
Press look impressively beautiful. The product range includes
special press ingots, which offer
an increased level of opacity for
cases in which the underlying
tooth structure is discoloured.
These ingots effectively mask
dark areas and provide a naturallooking aesthetic result, even if
the teeth are discoloured.

Precisely to prescription
In the case presented here,
teeth #13 to 23 were restored with
non-prep veneers. The highly
translucent IPS e.max Press HT

ﬂ page 18

ingots are particularly suited for
this type of minimally invasive
thin restoration. First, the dental
technician creates an anatomical wax-up of the veneer using
organic wax that burns out
without leaving residue. In this
respect, the final occlusal relief
must be taken into consideration
as early as during the wax-up.
The subsequent application of
stain and glaze materials results
in a slight increase in the vertical
dimensions of the restorations.
AD

The technician should strictly adhere to the minimum thicknesses stipulated for the relevant
lithium disilicate glass-ceramic.
According to the manufacturer’s
directions, the minimum thickness of IPS e.max Press is 0.3 mm
in the cervical and labial area,
and 0.4 mm at the incisal edge
(Fig. 6).
The wax margins are tapered
towards the end. The transitions
between restoration and tooth
structure should be contoured
particularly carefully. In this way,

the need for later corrections can
be pre-empted.
It is well known that inexperienced technicians often find
it difficult to create such a thin
wax-up and thus tend to create
thicker wax-ups. However, it is
unnecessary to over-contour the
margins as a precaution, as the
technician may then have to rework the restorations after they
have been pressed and divested.
This takes time. Thus, it is best to
contour as suggested by the manufacturer right from the start.

The veneers are pressed in
a Programat EP 5000 ceramic
press furnace at 920 °C. Upon
completion of the press cycle,
they are carefully divested—adjustments are kept to a minimum. The sprues are separated
with thin diamond disks, whilst
the objects are kept moist and
cool. The attachment points are
smoothed out using light pressure and low speed. Next, the
restorations are tried in on the
dies of the model, and the contact
points, occlusion and articulation are checked. If necessary,
the surface texture may be adjusted.
After these steps have been
completed, the veneers are carefully blasted using aluminium
oxide at minimum pressure and
cleaned with steam before they
are matched to the tooth shade
with IPS e.max Ceram Glaze
and Stains and IPS e.max Ceram
Shades, individualised and
glazed (Fig. 7). They are best
tried in with Variolink Veneer
Try-In pastes. The translucency
and shade of these glycerine
pastes are identical to those of the
polymerised Variolink Veneer
luting composite and therefore
the composite shade, which provides the least perceptible final
result, can already be determined and tested before the
veneers are cemented in place.
This try-in is performed to check
the aesthetics of the veneers
only; the occlusion is not checked
at this point. After the try-in, the
water-soluble paste is removed
from the veneers in an ultrasonic
bath and then the veneers are
thoroughly dried.

Incorporation
The patient was impressed
with the veneers already at the
first try-in. Her smile-on (Fig. 8)
was an expression of her happiness and the practice team
was pleased. The veneers fitted
at the first go. The proximal contact points did not require any
adjustments. Consequently, the
restorations were incorporated
immediately.
As a basic principle, ceramic
veneers are inserted using an
adhesive technique. In preparing them, the inner surfaces
were cleaned with water, dried
and etched with 5% hydrofluoric
acid (for example IPS Ceramic
Etching Gel) for 20 seconds and
then carefully rinsed and dried.
Next, Monobond Plus was applied and allowed to react for
60 seconds in order to achieve
the necessary silanisation of the
lithium-disilicate veneers.
The patient’s enamel was
etched with 37% phosphoric acid
for 30 seconds, rinsed with water
and then lightly dried. Next, the
oral cavity was isolated with a
rubber dam.
The veneers were cemented
in place using light-curing Variolink Veneer. This translucent
luting composite is suited for
anterior restorations with a
thickness of less than 2 mm.
The restorations have to be sufficiently translucent for the luting
composite to be effectively light-

cured through them. Variolink
Veneer is available in a range of
value shades, which cause the
restoration in situ to appear
brighter or darker. This luting
composite ensures a strong bond
and high resistance to wear.
We selected Variolink Veneer
in the shade Medium Value 0
for the present case. This shade
is neutral and does not have
any effect on the brightness of
the restoration. An appropriate
amount of luting composite was
applied to the bonding surfaces
of the restoration and the
restoration was placed in situ
using light pressure. After the
surplus material had been removed, each veneer was lightcured for five seconds using a
bluephase 20i curing light.
Offering a reliable, high light
intensity of 2,000 to 2,200 mW/cm2,
the Turbo programme eliminates
the risk of insufficient polymerisation. The built-in fan ensures
a consistently high light intensity.
Excess composite material was
removed from the margins of the
restorations and then the cement
joint was polished with a soft silicone polisher.
Without a doubt, the thinner
and more delicate the veneers
are, the more difficult it is for
the clinician to place them. As
delicate and fragile the non-prep
veneers presented in this report
may appear when they are first
delivered, they are highly stable
and durable once they have
been inserted. The adhesive
bond with the enamel ensures
a long-lasting high stability and
optimal adhesive bond of the
restoration in situ.

Looking beautiful
In terms of aesthetics, the
treatment of this patient is a
complete success. The margins
of the restorations are tapered
very thinly and are not discernible from the tooth structure
even when examined from different angles (Fig. 9). The lower
dental arch has been re-shaped
as a result of the orthodontic
treatment and no longer contains gaps. The upper marginal
gingival contour has been
corrected to follow a ‘high-lowhigh’ pattern, which has a decisive effect on the pink-white
aesthetics. According to this
pattern, the gingival margins are
located higher on the upper central incisors than on the adjacent
lateral ones, while the margins
on the lateral incisors are located lower than on the canines.
If details such as this pattern are
not observed, the aesthetic result looks only half as good as
it should even if an otherwise
excellent restoration is placed.
The restorations reflect the
typical characteristics of the natural teeth. Figure 10 shows the
beautiful design of the surface
texture of the veneers, including
their shiny marginal contours.
The light is optimally transmitted through the veneers and scattered. The resulting reflections
and optical effects impart a natural-looking vibrant appearance

preparation is not a necessity.
Compared with conventional
veneers or crowns, non-prep veneers represent not only a highly
aesthetic, but also a minimally
invasive treatment option.

Fig. 7

Fig. 9

Non-prep veneers expand the
range of dental treatment options
and provide a viable route to meet
the patient’s desire for aesthetic
improvement, which previously
could not be carried out because
the resulting loss of tooth structure would have been unacceptable to both the patient and clinician. Hence, this treatment option, which has been used in
North America successfully for
quite some time and is becoming
increasingly popular, is also of
interest to young and young-atheart patients in Europe.

to the ceramic veneers. The
translucent effect of the lithium
disilicate glass-ceramic creates
a pleasant chameleon effect; the
contact points correlate to one
another and the incisal triangles
are shaped in a slightly open
curve. The gingiva does not show
any signs of irritation and it features a healthy stippled surface
texture.

These veneers offer a decisive advantage when placing
restorations with margins in
the visible area. In younger patients in particular, the gum
line may recede with increasing
age.
However, receding gum
lines do not present a disadvantage in terms of quality or aesthetics with these restorations,
as their margins are invisible.

Conclusion
In the present case, the patient’s expectations in terms of
shape, size and shade were optimally met. Her appearance was
favourably altered without sacrificing any dental hard tissue.
From the current vantage point,
non-prep veneers are thus indicated in cases in which misaligned teeth or differences in
tooth length negatively affect the
appearance of anterior teeth, and

Although the dentist does not
need to grind the teeth to place
non-prep veneers, the desired
result has to be accurately
planned and the procedure perfectly prepared. Insertion without guide grooves in particular
requires a maximum measure of
concentration and sure instinct.
Selecting an appropriate material is equally essential. With
its exceptional strength, the
IPS e.max Press lithium disilicate glass-ceramic is a material
suited for this purpose. Once
the delicate and fragile-looking
ceramic veneers have been adhesively placed in situ, they are
durable and stable. DT

DDS GP
This universal iTunes app
aims to offers dental practitioners a new way in patient consul-

tation. It includes over 120 diagnoses and procedures, displayed
through drawings, sketches,
X-rays, and photos, which are
easily accessible through a slider
that let’s you browse quickly
through the single steps of treatment. According to the manufacturer Genuitive Inc, patients
responded with a higher case
acceptance rate when their
dental practitioner was directly

explaining conditions and treatment plans with the aid of DDS
than when they were left alone to
watch a video or simply handed
printed brochures.
The full version is available at
the iTunes app store for US$399.
Users can also buy a trial version
with limited content for US$0.99.

Official news for visitors and exhibitors

Welcome to the first HKIDEAS
Hong Kong’s new premier showcase for dental professionals to be held in June 2010
n At HKIDEAS 2010, dental professionals from Hong Kong and abroad
will have the opportunity to get
hands-on with the latest products
and technologies that local and international dental companies have
to offer. The show, which is organised for the first time by the Hong
Kong Dental Association, will be
held from 18–20 June 2010 at the
Hong Kong Convention and Exhibition Centre. The organiser expects
a high number of participants from
all over South East Asia to attend
the congress. Among them will be
speakers from Hong Kong as well
as re-known international lecturers such as implant specialist Dr
Sascha Jovanovic from the United
States.
Hong Kong has remained a pivotal market for dental equipment in
Asia. According to the World Trade
Atlas, the city ranks first in Southeast Asia with an import value of
over US$40 million. A recent survey by the AXA Asia-Pacific Holding has revealed that health tops
the list of concern of Hong Kong people, above financial and other concerns. It also found that only 65 per
cent of the respondents had had
a medical or dental check-up in the

standards can be translated into
the daily routine of dental surgeries including the use of protective
gear and products for patient hygiene and the disinfection of surfaces and technical equipment.

last five years, ranking Hong Kong
the second lowest among all surveyed markets including Australia,
France, Germany, Japan, and the
United States.
The organiser announced that
HKIDEAS 2010 will have much to
offer to all members of the dental
profession. The latest materials,
technologies and equipment for
clinical dentistry from the world’s
leading manufacturers, as well as
a range of supporting services for
dental practices, will be on display.

Implantology, for example, is
a growing field in South East Asia
and the percentage of treatments
that involve the use of fixed
tooth replacements continues to increase. A number of manufacturers have announced that they will
showcase innovative implant surfaces, which help to ensure faster
bone integration and shorten healing time.
In addition, new solutions presented by prevention specialists
will demonstrate how hygiene

CAD/CAM as one of the most important developments in dentistry
today will have a large share at
HKIDEAS as prices for systems
continue to drop, making them
increasingly affordable to dental
laboratories. Despite the many
challenges that this technology has
faced, such as uncertainty regarding the viability of zirconia material for dental prosthetics and the
technology’s economical feasibility, it has progressed and continues
to adapt in order to offer greater
versatility in services to both small
and large dental labs.
The organisers has announced
that it will provide a comprehensive exhibitor guide that will include details about the companies
and the category of products they
are exhibiting. The guide will be
available to all participants upon
registration.

HKIDEAS – A joint effort in global oral health enhancement
Welcome message by Dr Sigmund Leung, President of the HKDA and Chairman of the Organizing Committee of the 1st HKIDEAS

Dr Sigmund Leung

n This year marks the 60th anniversary of the founding of Hong
Kong Dental Association—a significant milestone for our profession. Adding to the festivity, we
are most delighted to bring you
the 1st Hong Kong International
Dental Expo And Symposium
(HKIDEAS).

Situated at the confluence where
East meets West, Hong Kong has
been an ideal place for international exchange in various aspects
and there is no exception for dental knowledge. Given the unique
strength arising from Hong Kong’s
reunification with the Mainland,
the Association surely is the best
platform for bringing international
efforts together in accelerating
global oral health. On this bridging
role, HKIDEAS will be the most
convenient channel for our worldwide dental colleagues to update
and exchange dental information
for the benefit of all populations.
On top of numerous quality symposiums, it is encouraging to see
the innovative line-up of programme including “Primary Dental
Care Forum”, “Knowledge Transfer
Forum”, “Greater China Forum”
as well as a luncheon summit focusing on China’s role in Global
Oral Health. Preeminent speakers
around the world are invited in

a bid to promote joint efforts in
global oral health enhancement.
HKIDEAS is the first international congress created by our Association, signifying our determination in performing a more prominent role in driving the profession
to a higher plane within the region.
We strive to provide you with a
perfect environment for knowledge exchange and a scientific programme with innovative “ideas” to
meet different information needs.
I would like to extend my hearty
thanks to all members of the Organizing Committee for their enormous effort to make the event happen. I am indebted to all speakers,
sponsors and trade exhibitors for
their invaluable contributions and
support. May I also wish all participants a most fruitful experience
and pleasant stay in Hong Kong.
Thank you and look forward to
seeing you again.

contain potassium salts to interrupt the neural
response to pain stimuli. It is effective but often
takes 4 to 8 weeks for pain relief. Other
desensitizing toothpastes contain strontium salts
to occlude open dentinal tubules from external
stimuli associated with dentine hypersensitivity.
Certain patients, however, do not find it effective.
New desensitizing toothpastes with arginine and
calcium carbonate (Arginine-CaCO3) that occludes
and blocks open dentinal tubules, are now
available in the market. Our study on 390 adult
patients with dentine hypersensitivity
demonstrated significant pain relief after using
professional desensitizing paste with
Arginine-CaCO3.1 The new Colgate® Sensitive
Pro-Relief™ desensitizing toothpaste containing
Arginine-CaCO3 and fluoride is developed for
routine daily use.
