Breakthrough Technology That Will Revolutionize The Treatment Of Tooth Decay
Quantum Dental Technologies, a Canadian
diagnostic device company, revealed its breakthrough technology which
detects and monitors the early onset of tooth decay without the need for
dental x-rays. It reduces the number of invasive and painful procedures,
and encourages better oral health. Quantum introduced its Dental Caries
Detection System prototype, known as The Canary System, at the
International Association for Dental Research (IADR) Conference in Toronto,
Canada.
"Dentists are limited in their abilities to detect and monitor the
early stages of tooth decay with traditional diagnostic tools such as the
X-ray and visual examination," said Dr. Stephen Abrams, Chief Executive
Officer of the Toronto-based Quantum Dental Technologies and dental
clinician. "Now, with this innovative new system that is pain free,
non-invasive and provides early caries detection, we can finally move away
from intervention, or the filling of cavities, to focus on prevention and
actual remineralization or healing of small areas of tooth decay."
The Canary System uses a handheld laser that emits a low-power light to
examine tooth surfaces. When laser light is shone onto the tooth, the
system measures the level of glow (luminescence) and heat released from the
tooth. Laser light interacts differently with healthy teeth than with
decayed teeth. By varying the pulse of the laser beam, a depth profile of
the tooth can be created to permit detection of decay as deep as 5mm from
the tooth surface and as small as 50 microns in size (20 times smaller than
a millimeter). With The Canary System, the dentist is able to identify
areas of decay much earlier than with current methods.
This technology is based on extensive research including 30 published
research articles in peer-reviewed dental and medical journals. The Quantum
Dental group is presenting three posters at the IADR conference on this new
technology.
The Canary System can scan for caries on smooth enamel surfaces, root
surfaces, biting surfaces, between teeth, and around existing fillings.
Current methods are not as sensitive in detecting early decay in these
areas.
Early detection of dental caries within the enamel shell of the tooth
allows applied remineralization therapies to halt or delay the decay. These
therapies work to repair the teeth by recrystalizing the minerals onto the
enamel surface. If detection of decay is delayed until it has broken
completely through the enamel shell, remineralization will not work and a
filling is required.
For patients, the placement of a dental filling is an invasive
procedure which causes some short term trauma to the tooth. Restorations do
not last a lifetime, and there is a cycle of continued placement and
replacement of fillings. Each new restoration gets larger, eventually
leading to more invasive treatments including crowns, root canal or
extraction.
The Canary System:
- Is less invasive and safer than traditional approaches for detecting
and monitoring early-stage tooth decay;
- Extends the natural lifecycle of the tooth by providing a chance to
remineralize the decayed area;
- Eliminates the need for painful needles and fillings;
- Reduces the cost barriers to dental services by treating small
"cavities" before invasive and more expensive technologies are
required.
"For dentists, The Canary System will open up a new source of patients
needing care," says Dr. Abrams. "Other clinical staff such as dental
hygienists or assistants may perform the procedure and administer
remineralization treatment. It's a win-win for everybody."
"For the research community, it means a sensitive, non-invasive device
for monitoring tooth decay in the lab or in field trials," says Dr. Andreas
Mandelis, Professor at the University of Toronto and President of Quantum
Dental Technologies. "The technology is robust and will provide the
researcher with a real-time view of the lesion without destruction of the
tooth."
The Canary System will be in clinical trials for the next 18-24 months
with collaborators in both research and clinical settings, and will be
ready for market release in 2010.
