To determine the possible associations of dental disease with medical status, cohort study was conducted from 1995 to 1999. The subjects were 18,114 men and 6,188 women aged 20+ in baseline year, and 920 men and 165 women in follow-up years, from 1997 to 1999. They were examined the number of invisible tooth(functionally missing teeth) and medical condition(blood pressure,- body mass index, fasting plasma glucose, hemoglobin, total cholesterol, aspartate transaminase,hematuria, smoking, and cardiovascular disease history) in Occupational Health Center of Incheon Severance Hospital. In this study only men were included in statistical analysis.
To assess the strength of associations between functionally missing teeth with medical status, odds ratios and 95% confidence intervals were computed using logistic regression models through the Window SAS 6.12 while age, smoking, fasting plasma glucose were adjusted as, conditional confounding variables.
The results were as follows;
Older, higher blood pressure, and cardiovascular disease history were associated with increased risk of occurrence of one more missing teeth than baseline year in men. Odds ratios were 1.76(by 10 years), 1.32(by 10mmHg), and 3.21(in cardiovascular disease history), respectively. These results explained about only men.
In summary, hypertension and cardiovascular disease history´ may be a potential risk factor to dental health while age, smoking, and fasting plasma glucose were adjusted as conditional confounding variables. But this association should be further investigated for their causal relationship.
