Materials and methods: This study was done on Forty healthy-looking dental students in Tikrit University, with age range between 19-24 years, stimulated mixed saliva were collected from them and the supernatant part of it were subjected to analysis by Atomic Spectrophotometer in analytical center of chemical engineering college/ Tikrit University, to estimate Zinc concentration. Assessment of caries prevalence was carried out by clinical examination using DMFT and DMFS indices. Zinc concentration and dental caries experience took place in relation to gender.
The result showed that the Zinc level in saliva of caries experience group was 76.6±20.6 ng/ml, while that of caries free group was 72.6±32.3 ng/ml. The total mean of saliva Zinc concentration in saliva of males in both groups was higher than females.
Saliva zinc concentration was higher in individuals with caries free when compared with individuals having caries experience. The severity of dental caries was associated with the increasing salivary zinc concentration. There was significant differences between the salivary zinc concentration in both sexes. Males in both groups having higher salivary zinc concentration than that in females.
