Abstract

In order to comparatively observe the salivary cariogenic factors contributing to permanent tooth caries development in each sexes of Korean, the author performed estimation of unstimulated and stimulated salivary flow rates, salivary viscosity test, and salivary buffering capacity test in 50 males and 50 females Koreans aged form the age 20 to 29. Thereafter, the data from the four kinds of caries activity test were analysed and evaluated comparatively. The obtained results were as follows. 1. Unstimulated salivary flow rate for five minutes was 2.2ml in males and 1.7ml in females but the sexual difference was not significant statistically. 2. Stimulated salivary flow rate for five minutes was 7.1ml in males and 4.8ml in females. 3. Salivary viscosity was 1.9 in males and 1.7 in females but the sexual diffrence was not significant statistically. 4. Salivary buffering capacity was 8.5 drops in males and 6.7 drops in females 5. It seems the stimulated salivary flow rate and buffering capacity to be the anti-cariogenic factors in the occurrence of permanent tooth caries in Koreans.
