Abstract: Many studies have found that an association exists between periodontitis and coronary heart disease. The potential mechanism linking periodontitis and coronary heart disease might be that the oral microbes directly trigger atherosclerotic development or indirectly influent the risk factors of coronary heart disease. The findings of epidemiological investigation on the association between periodontitis and cardiovascular disease, the potential biological
mechanism, and the recommending periodontal treatment for the prevention of coronary heart disease were discussed.
