Number of Teeth as a Predictor of Cardiovascular Mortality in a Cohort of 7,674 Subjects Followed for 12 Years

Background: That oral health is related to the development of different cardiovascular disorders is reported in a number of studies. This study investigates if different parameters of oral health are associated with future mortality in different cardiovascular disorders in a dose‐dependent manner. Methods: A total of 7,674 subjects (3,300 males and 4,374 females; age range 20 to 89 years) received a dental examination by specialists in periodontology between the years 1976 and 2002. Number of remaining teeth, severity of periodontal disease, number of deepened periodontal pockets, and bleeding on probing were evaluated in relation to cause of death. Results: During a median follow‐up period of 12 years, 629 of the subjects died. For 299 subjects the cause of mortality was cardiovascular disease (CVD); 167 of these subjects died from coronary heart disease (CHD); 83 died from stroke; and 49 died from aortic aneurysm or congestive heart failure. The causes of death for the remaining 330 subjects were other than CVD. After adjustment for age, gender, and smoking, number of remaining teeth predicted in a dose‐dependent manner all‐cause mortality and mortality in CVD and in CHD (P
