Abstract

Objectives: to analyze the effect of salivary pH variations on the hardness od bulk-fill composite resin. Method: this research is an experimental study with a post-test only with control group design. 28 samples of bulk-fill composite resin with 8 mm diameter and 4 mm thickness. The samples devided into 4 groups, group I was immersed in saliva pH 5,3, group II was immersed in saliva pH 6,6, group III was immersed in saliva with saliva pH 7,8, and the control group which was not treated. The hardness of the sample was measured using Vickers Hardness Tester. The data were analyzed using Analysis of Variance (ANOVA). Result: the result showed that there were no significant differences in all groups with p value = 0,474 (p>0,05). Conclusion: salivary pH variations have not significantly affect the hardness of bulk-fill composite resin.
Keywords: salivary pH, bulk-fill composite resin, hardness.
