This study was carried out to determine if the amount of inorganic substance in saliva could be influenced by various dental filling materials. The contents of Ca, Mg, K, Zn and P in mixed saliva were measured by atomic absorption spectrophotometer. The results obtained were as follows: 1. Ca and P contents in saliva was increased by aging. 2. Change of P contents in saliva by sex were not remarkable. 3. Salivary Ca contents in caries-resistant group was average 5.95mg%, and 4.97mg% in caries-susceptible group. the latter showed decrease of about 1mg% compared to the former. Salivary P contents in caries-resistant group was average 14.8mg%, and in caries-susceptible group 13.7mg%. the latter showed decrease of approximately 1mg% compared to the former. 4. Salivary Mg contents by age was gradually increased until the age of thirties and decreased in forties. K contents was decreased by aging, while Zn contents had no change. 5. Mg contents by sex was somewhat higher in male while there were no significant differences between male and female in K and Zn contents. 6. Salivary Mg contents in caries-resistant group was average 390μg% and 497 μg% in caries-susceptible group, and it showed the increase of about 100μg% in the latter. However, there were no significant differences between two groups in K and Zn contents. 7. In cases of restorations salivary Mg contents was increased.
