Assessment of shear bond strength between composite resin and enamel surface after treating with acid etching and laser etching: a comparative study
Dr Prashant Acharya, Dr Neesha Kumari

Background: The objective of this study was to assess the shear bond strength between composite resin and enamel surface using laser etching as well as acid etching techniques. Materials and methods: For the purpose of this experiment, a total of 100 freshly excised maxillary canines were utilized. Subsequently, the subjects were primarily categorized into two distinct groups: Group 1 participants underwent acid etching followed by enamel bonding, while Group 2 participants underwent laser etching followed by enamel bonding. The composite bonding procedure was performed on the enamel surface, following the approach of each group. Results: The average shear bond strength of Group 1 was determined to be 39.55 MPa, while Group 2 had an average shear bond strength of 24.12 MPa. Upon doing statistical analysis, it was noted that the acid etching group had a considerably higher average shear bond strength compared to the laser etching group. Conclusion: The average shear bond strength of the composite material was greater following acid etching in comparison to the composite material bonded after laser etching. Keywords: Composite resin, acid etching, laser etching
