Abstract:

Objectives: In Japan, universal health coverage was established in 1961. Since then, Japanese people have had easy access to dental treatment and adequate insurance coverage thereof. Meanwhile, although a large body of evidence indicating a relationship between oral health and general health has accumulated, little research has assessed the effect of dental care on general health promotion.
The purpose of this study, conducted by the 8020 Promotion Foundation, was to evaluate the effects of oral health on general health via a prospective cohort study.

Methods: The baseline participants were 12,278 dental patients (4,392 males and 7,886 females, ages 20 and over) residing in 46 prefectures of Japan who visited a dental clinic during a one-week period in 2014. The two-year cohort analyzed in this study included 5,132 participants (1,729 males and 3,403 females, ages 40-69). The general health of participants was evaluated by the incidence of non-communicable diseases such as diabetes, cerebrovascular disease, heart disease, cancer, hypertension, and hyperglycemia, and perceived general health was assessed by self-administered mail questionnaire. Dentists directly evaluated the dental status of participants. A multiple logistic regression analysis was conducted.

Results: The analysis found that number of teeth was a significant factor related to incidence of diabetes during the two-year period, after adjusting for confounding factors such as age, gender, masticatory function, and continuous regular dental check-ups (Odds ratio: 0.57, 95%CI: 0.35-0.95, p=0.029). Regarding the deterioration of perceived general health status, number of teeth was again found to be a significantly correlated factor (Odd ratio: 0.68, 95%CI: 0.54-0.87, p=0.002).

Conclusions: These results indicate that number of teeth is a contributing factor in the prevention of diabetes and the maintenance of general health. The effects of dental care on general health require further study, including extending the participation period.
