ABSTRACT
Objective: The aim of the study was evaluation of the effect of different dentintreatment using immediate dentin sealing or Er: YAG laser on adhesion of prefabricated resin composite inlay.
Study Design: Comparative Study
Place and Duration of Study: This study was conducted at the College of Dentistry, Qassim University, Kingdom of Saudi Arabia from November 2018 till December 2020.
Materials and Methods: The study teeth comprised 45caries free molars which were divided into three equal groups. The occlusal third of the crowns were cut with a slow-speed diamond saw. The groups were classified as follows: group A, dentin etched with 35% phosphoric acid for 10 s directly prior to luting procedures. Group B, immediate dentin sealing is done directly after cavity preparation. Group C, dentin surface treated with 100 mjEr: YAG laser directly prior to luting procedures. The resin composite inlays were adhered to different treated dentin surface using adhesive resin cement. The specimens with their adhered inlays of each group were subjected to shear bond strength testing. Analysis of the recorded shear bond strength values (Mpa) were done using one-way analysis of variance and Tukey post hoc test. Statistical analysis was performed using Graph pad Prism-6 statistics software for Windows P values ≤ 0.05 are considered to be statistically significant in all tests.
Results: Shear bond strength mean values for Group B>Group C >Group A.
Conclusion: IDS and Er:YAG laser improve the shear bond strength of composite inlays to dentin
Key Words: Immediate dentin sealing -Er: YAG laser - Delayed dentin sealing Composite inlay.
