RESUMO
OBJECTIVES: Chronic periodontal infections may predispose to cardiovascular disease. Since tooth loss may be due to periodontitis it is assumed that tooth loss can also predisposes cardiovascular disease. The aim was to investigate the possible relationship between the severity of the clinical picture of periodontitis and the occurrence of cardiovascular disease. METHODS: We evaluated the association between clinical periodontal parameters, tooth loss and cardiovascular incident. A total of 100 subjects (50 subjects diagnosed with cardiovascular disease and 50 in control group without cardiovascular disease) underwent a dental examination. Tooth loss in all participants was caused only as a consequence of periodontitis. In addition to periodontal status, conventional risk factors for cardiovascular diseases (hypertension, smoking, obesity, hypercholesterolemia, diabetes) were measured, too. RESULTS: Periodontal status was worse in patients in the group with cardiovascular disease compared to the group without cardiovascular disease. A significant association was observed between tooth loss levels and cardiovascular disease. In the group of patients who had cardiovascular disease, tooth loss was more than 50%. In the group of patients without cardiovascular disease, tooth loss was about 20% of the total number of teeth. A significant association was observed between tooth loss levels and cardiovascular disease prevalence. CONCLUSION: This study presents relationship between number of teeth and cardiovascular disease, indicating a link between oral health and cardiovascular disease.
