Abstract

Introduction: Recently, ER:YAG LASER has been used for tooth preparations and silorane-based composites have been introduced to dentistry, though investigating this type of composites has received scant attention. Therefore, the aim of this study was to compare microtensile bond strength (MTBS) of silorane- based composite (Filtek P90 3M/USA) to enamel sufaces, prepared by ER:YAG LASER irradiation versus BUR cut.Methods:Same sized cavities were prepared by ER:YAG LASER and BUR on the enamel of 20 extracted teeth which were randomly divided into 4 groups:E1 laser + acid etching, E2: laser, E3: BUR + acid etching, E4: BUR. Then primer, adhesive and P60 resin composite were utilized according to the manufacturer instructions. After thermocycling, 20 samples were created in the form of an hour glass model with 1 mm2 slices in each group, and were tested by SD Mechatronic MTD 500 (Germany) machine with cross head speed of 1mm/min to create the fracture. The failure mode was assessed under stereomicroscope (ZTX-3E, Zhejiang/China), and the study data were analysed by ANOVA test. Results: The study results revealed that highest and lowest microtensile bond strength belonged to E3 and E2 group respectively. No significant differences were observed between the tested groups(p= 0.213). Highest and lowest modes of failure were adhesive and cohesive respectively. ANOVA results did not demonstrate any significant differences between groups(p=0.845).Conclusion: Laser-prepared or BUR-prepared cavities with or without etching and silorane based composite could not significantly affect MTBS in order to enamel.
