Periodontal Health and the Heart

JAMA. 2006;295(15):1763. doi:10.1001/jama.295.15.1763-d

Periodontal infection is associated with coronary heart disease (CHD), according to a report by researchers in Germany (Spahr A et al. Arch Intern Med. 2006;166:554-559).

Chronic inflammation has been linked to increased cardiovascular risk, and periodontitis is a possible trigger of chronic inflammation. To look for a link between periodontal infection and CHD, the researchers enrolled 263 patients with stable CHD and 526 controls without a history of CHD and collected subgingival biofilm samples to analyze for periodontal pathogens.
