Aim: this study was conducted to compare the effects of different intracanal medicaments on microhardness of dentin. Materials and Methods: The dentin disc of third molars (n = 45) was obtained and was randomized into three groups. Group metapex, modified triple antibiotic paste (MTAP), and control group according to the medicaments used. Teeth were incubated in 100% humidity for 7 days. For each group, teeth were subjected to microhardness testing. The one-way analysis of variance test was used to check mean differences among the groups. Post hoc analysis was done using Tukey's Honest Significant Difference test. Results: Significant differences (P < 0.001) in mean microhardness of dentin between the control group and medicament group. The intergroup comparisons of metapex and MTAP group did not show any statistically significant variations (P > 0.05) in mean microhardness of dentin after the 7th day of application. Conclusion: Under the condition of this study, MTAP affects the microhardness of dentin adversely compared to the metapex.
