Abstract
Objective: To evaluate the microleakage of the different cements and dentin before and after using Nd: YAG laser. Method: Forty-eight human molars were randomly divided into two groups: laser group and control group, and composite resin inlays were fabricated indirectly .Teeth in the laser group were processed with pulse Nd: YAG laser(0.8 W, 10 Hz) .Then, composite resin inlays were luted with 6 cements.After 7 days of storage in water at 37 ℃ , specimens were subjected to 300 thermocycles ranging from 4 ℃ to 55 ℃.Then.they were placed into a 0.5 % basic fuchsin dye for 24 h.After soaking,specimens were longitudinally sectioned into four sections.Subsequently,the specimens were observed for microleakage using dental microscope.All statistical analysis was performed using SPSS 17.0 software package. Result: The microleakage between 6 cements and dentin.was all decreased after using Nd:YAG laser, and there was significant difference among former 2 cements on marginal adaptation (P <0.05) .Resin cements showed lower microleakage than other cements. Conclusion: Nd: YAG laser (0.8 W, 10 Hz) can increase the marginal adaptation and decrease the microleakage between cements and dentin.关键词
