FOR IMMEDIATE RELEASE: April 10, 2007 SMALL BACTERIA – BIG IMPACT
Two studies look at the possible connection periodontal bacteria may have with other systemic conditions CHICAGO – Two new studies in the Journal of
Periodontology explore the possible link between periodontal bacteria
and
coronary artery disease as well as periodontal
bacteria and preeclampsia. These studies found that periodontal
bacteria,
which are often invisible to the naked eye, may account for big effects on general health conditions. Periodontal bacteria have often been thought to
play a role in many of the possible connections between oral health
and
overall health. Two of the studies in this month’s issue of the JOP further the understanding of these potential connections. One study looked at patients who had been diagnosed with coronary artery disease and examined the bacteria found in their arteries. They were able to identify periodontal pathogens in the coronary and internal mammary arteries in 9 out of 15 of the patients examined. A second study looked at women who had suffered
from preeclampsia during their pregnancy, a condition characterized by
an
abrupt rise in blood pressure that affects about 5% of pregnancies. The study found that 50% of the placentas from women with preeclampsia were positive for one or more periodontal pathogens. This was compared to just 14.3% in the control group. Both of these studies support the concept that periodontal organisms might be associated with the development of other systemic conditions such as coronary artery disease and preeclampsia. “These studies are just a few in the growing body
of evidence on the mouth-body connection. More research is needed
to
fully understand how periodontal bacteria travels from the mouth to other parts of the body as well as the exact role it has in the development of these systemic diseases,” said Preston D. Miller, Jr., D.D.S., and president of the American Academy of Periodontology. “In the meantime it is important for physicians, dental professionals and patients alike to monitor the research in this area as it continues
to grow so they can better work together to achieve the highest
levels
of overall health.” To find out if you are at risk for periodontal
diseases please visit the AAP’s Web site at

Effect of electrophoretically activated calcium hydroxide on bacterial viability in dentinal tubules--in vitro. Tsesis I, Zukerman O, Weiss EI, Fuss Z. Department of Endodontology, The Maurice and Gabriela Goldschleger School of Dental Medicine,

To evaluate the ability of electrophoretically activated calcium
hydroxide (CH) to eliminate bacteria in dentinal tubules.
In an in vitro model of dentinal tubule infection, 18 cylindrical
root specimens prepared from freshly extracted bovine
teeth were used. After removal of the smear layer, intracanal dentinal tubules were infected with Enterococcus faecalis for 21 days. In 12 specimens, CH paste was placed in the root canals for
7 days. In six of these, an electrophoretic current (10 mA per 10 min), using two electrodes, was applied after placing the medicament in the canal. Powder dentin samples obtained from within the canal lumina using ISO 025, 027, 029, 031 and 033 burs were examined for the presence of vital bacteria by inoculating agar plates and counting colony forming units. anova with repeated measures was used to analyze results. A significant difference was found between experimental groups and the positive control group. CH and electrophoretically activated CH significantly (P < 0.001) reduced bacterial viabilities in dentinal tubules to a depth of 200 microm. Treatment with electrophoresis was significantly (P <0.001) more effective than pure CH in depths of 200-500 microm. Specimens treated with electrophoretically activated CH showed no viable bacteria in dentinal tubules to a depth of 500 microm from the root canal space within 7 days. The time required for treatment of pulpal infection root resorption may be decreased, thus minimizing the risk of coronal fractures in young patients with traumatized teeth. | ||
