The Cariostat and Snyder tests which are sometimes insufficient for forecast used for the caries activity test in clinical preventive dentistry. The caries is a multifactorial disease, for which it is considered necessary to introduce various kinds of tests to clarify many oral environmental factors. It is currently recognized that no significant correlation is found between resting salivary flow rate and present carious condition and between resting salivary pH and present carious condition. The salivary condition, which is changed by the various foods, should be estimated during the positive activity against the factor of the caries. A total of eighteen females aged 19 to 21 were examined for change in time of salivary flow rate and pH after ingesting five kinds of foodstuffs. The results were as follows : 1. Salivary flow rate after ingesting one of five kinds of foodstuffs tended to increase and reached a muximum in the first 3 minutes and return to the resting salivary level in the next 5 minutes. It was hard to find any variations after 13 minutes. 2. No significant difference in the salivary flow rate was observed between any two foodstuffs for each measured time. 3. Salivary pH after ingesting cola tended to decrease with an increase in time. However, those of others increased and showed a muximum in the first 3 minutes. Salivary pH after ingesting chocolate or almond was not significantly lower than the resting salivary level for each measured time. 4. Salivary pH was higher after ingesting almond than after ingesting cola or Yakult. No significant difference was found in the salivary pH in each foodstuff after rinsing. 5. In each correlation of resting salivary flow rate and of resting salivary pH with average number of DMFT and with average number of DT exhibited no significant correlation.
