What's new in Dentistry?
Cosmetics
Dental Implants
Air abrasion technology
Many cavities can now be treated without the use of the so-called "drill". This
innovation allows decay to be cleaned out of a tooth by use of
a fine stream of air mixed with microscopic particles. In most
cases, anesthetic is not necessary, and this technique is ideal for
the placement of cosmetic composite fillings, which are tooth-colored. We
have found that patients especially appreciate the relative lack of
noise, and this works wonderfully with childen.
Lasers
While lasers have certainly garnered considerable media attention,
their broad use in Dentistry is, at present, somewhat limited. The
reason for this fact is that they work very slowly. Additionally,
the very high equipment and time costs will effect a substantial
increase for the cost of fillings. In our opinion, however,
the major advantage of the use of lasers in the preparation of cavities
in teeth is still psychological. Lasers are ideal for other
purposes in the mouth, most notably for soft-tissue surgery or possibly
for fast-curing of composite fillings.
Gum Disease and Prevention
We
have long known that bacteria cause gum disease, but the use of long
term antimicrobials/antibiotics has been discouraged, because of
the possibility of bacteria developing resistance, and other factors
such as tooth discoloration.
There
are now several recently introduced products which have passed
FDA scrutiny, which are designed to help control periodontal disease. They
are all designed to be used as adjunct to standard therapeutic
root planing (deep
cleaning).
One product
is a dissolvable chip (Perio-Chip), saturated with the antimicrobial
agent used in surgical hand soap, chlorhexidine gluconate,
which is placed under the gumline. This agent has proven to work
well as an antimicrobial mouth rinse, however its chief disadvantage
as a rinse has been that long term use often results in heavy staining
of the teeth.
Another
similar product is an antibiotic-impregnated gel (Atridox)
which is squirted under the gumline, where it hardens and also gradually
dissolves.
Both of
these products gradually release the antibacterial medication over
a period of several weeks.
Also,
now there is a pill (Periostat), which can be taken daily
which studies have indicated may slow the progress of periodontal
disease. It uses
a subtherapeutic dosage of the antibiotic doxycycline, which
in higher doses is commonly used to treat oral infections. Although this is a commonly
prescribed drug, it has been awarded FDA approval not because of its antibacterial
action, but because some studies have indicated that it inhibits the breakdown
of some of the connective tissue components of gum tissue.
