Abstract

The author performed Snyder test, estimation of salivary flow rate, salivary viscosity test, salivary buffering capacity test, M-R test, oral hygiene ability test, estimation of oral glucose clearance time and plaque reformation test in the 107 male Koreans aged form the age of 20 to 29, in order to detect and control the active cariogenic factors contributing to caries development on the individual basis. Thereafter, the data from 8 kinds of caries activity test were analysed and evaluated. The obtained results were as follows: 1. Snyder test was positive in 86.0% of total tested persons, and among those showing positive Snyder test reaction, slight caries activity was appeared in 39.1%, moderate caries activity in 23.9%, and marked caries activity in 37.0%. 2. Salivary flow rate was under the average flow amount in 53.3%. 3. Salivary buffering capacity was low in 22.4%. 5. Buffering capacity of dental plaque was high in 12.5%. 6. Oral hygiene ability was insufficient in all persons tested. 7. Oral glucose clearance time was long in 42.1%. 8. Plaque reformation rate was high in 8.4% of the 107 persons tested.
