title: [Does chronic periodontitis play a role in the pathogenesis of cardiovascular and cerebrovascular diseases?].
abstract: The role of chronic infections in the initiation of atherosclerotic lesions has been vividly discussed in recent years. A possible causal relationship between cardiovascular diseases and infections with, e. g., Chlamydia pneumoniae, Helicobacter pylori, or herpes viruses had also been established for chronic periodontitis, in particular after discovery of DNA of typical periodontal pathogens in atheromatous plaques. Especially in longitudinal epidemiologic studies, a low or moderate association between existing periodontitis and the development of, e. g., coronary heart disease or non-haemorrhagic stroke had been observed. In this article the respective literature is critically reviewed. In particular, the influence of incomplete or inappropriate adjustment for common risk factors for both diseases, i. e., cardiovascular disease and periodontitis should be analysed. In metaanalyses of prospective studies, in which the respective endpoint occurred after the investigation had commenced, relative risks of periodontitis of 1.12 (95 % confidence interval 0.95-1.33) for coronary heart disease and 1.73 (0.89-3.34) for ischaemic stroke were calculated. Whether chronic periodontitis actually represents an important risk for the development of cardiovascular diseases remains questionable. Already planned intervention studies appear to be premature and ethically highly problematic.
