CHICAGO—February 13, 2007—Eliminating dental plaque may be an important step in preventing periodontitis and coronary artery
disease according to a study published in the Journal of Periodontology.
Researchers examined 20 individuals with chronic periodontitis. In 13 of the 20 patients, bacterial pathogens most frequently found in severe chronic periodontitis were also found in atherosclerotic plaque of coronary vessels. In 10 cases, those species of bacteria were also present in atherosclerotic plaque and in subgingival plaque”. (Atherosclerosis is a multistage process set in motion when cells lining the arteries are damaged as a result of high blood pressure, smoking, toxic substances and other agents.)
“We found that patients with periodontal pathogens detected in atherosclerotic plaque had four millimeters or greater of deep periodontal pockets and a significantly higher bleeding index,” said study author Dr. Maciej Zaremba. “This supports the possibility that bacteria associated with periodontitis can permeate into coronary vessels.”
“Since periodontal and cardiovascular diseases have several common risk factors, more studies are needed to evaluate the strength of
association between the two diseases,” said
According to the American Heart Association, coronary heart disease is the number one single cause of death in the United States. Knowledge of the risk factors and possible links to coronary heart disease, such as periodontal disease is the first step towards preventing it.
