Association between periodontal disease and cardiovascular disease

ABSTRACT

Studies have supported the notion that subjects with periodontitis and patients with multiple tooth extractions as a result of chronic advanced periodontal disease [PDD] have a greater risk of developing Cardiovascular disease [CVD] than those who had little or no periodontal infection. Periodontitis may predispose affected patients to CVD by elevating systemic C-reactive protein level and pro-inflammatory activity in atherosclerotic lesions and accelerate development of cardiovascular diseases. Oral health variables including loss of teeth, positive plaque Benzoyl-D-LArginine- Naphthyl Amide test [BANA] scores, and compliant of xerostomia may by considered as risk indicators for CVD. Exact mechanism which links PDD and CVD has not been firmly established. The link between PDD and CVD may be attributed to bacteria entering blood stream and attaching to the fatty plaque in coronary artery and contributing to clot formation which can lead to heart attack. Inflammation caused by PDD increases the plaque build up. The association between the two disease entities is cause for concern. However, dental and medical practitioners should be aware of these findings to move intelligently to interact with inquiring patients with periodontitis. They should be urged to maintain medical surveillance of their cardiovascular status, and work on controlling or reducing all known risk factors associated with CVD, including periodontal infection
