Background: It has been reported that people with teeth loss have an increased risk of cardiovascular disease. However, there is limited evidence for the specific relationship between remained teeth and cardiovascular disease (CVD).
Method: Among subjects who participated in Korea National Health and Nutrition Examination Survey conducted in 2008-2013, a total of 12,612 adults with mean age of 60.2±1.2 years old were analyzed. Number of teeth was classified as number less than 20, from 20 to 27 and more than 27. Multiple logistic regression analysis was performed to determine the relationship between cardiovascular disease and remained teeth number after adjusting for potential confounders.
Result: The prevalence of cardiovascular disease was 6.5%, 3.3% and 1.4% respectively in groups having number less than 20, 20 to 27 and more than 27 (P< 0.001). Total number of cardiovascular disease was 666. Diabetes, hypertension, total cholesterol level, waist circumference, metabolic syndrome had large proportion in a group having less than 20 teeth (P< 0.001). People having less than 20 remained teeth had statistically significant cardiovascular disease after adjusting for age, sex, body mass index, smoking, drinking alcohol, exercise, education, income status, stress, diabetes, and hypertension. A group having less 20 teeth was likely to have statistically significant relationship with cardiovascular disease. (Odds ratio [OR]: 1.41, 95 % confidence interval [CI]: 1.06-1.89) and stroke (OR:1.90, CI:1.03-3.48).
Conclusion: Our findings suggest that the number of remained teeth could be a useful additional indicator for assessing cardiovascular disease and stroke
