The relationship of periodontal disease to cardiovascular diseases--review of literature.

Abstract

Association of Oral and Systemic diseases has gained importance because the high occurrence of oral diseases is an extremely common source of infection. Epidemiological Studies have presented periodontal diseases as a risk factor for development of cardiovascular diseases. A chronic oral infection such as periodontitis is a constant potential source of infection and has now been considered as a separate risk factor for cardiovascular diseases, cerebrovascular diseases, peripheral arterial disease and respiratory diseases as well as delivery of low-birth-weight infants. The possible pathways linking oral infections to systemic diseases are metastatic infections, bacterial endotoxins, and systemic vascular injury. People with a history of periodontal disease and/or tooth loss were found at higher risk for Peripheral arterial disease (PAD) as compared to those without periodontal disease and/or tooth loss. All studies on the relationship of periodontal diseases to cardiovascular diseases are inconclusive and most of the data is based on epidemiological studies.
