Assessment of shear bond strength between composite resin and enamel surface after treating with acid etching and laser etching: a comparative study

Main Article Content

Abstract

Background: This study had been carried out for the comparison the shear bond strength of composite resin to enamel surface with laser etching and acid etching. Materials and methods: To carry out this study, a total of 100 maxillary canines that had been recently extracted were utilized. These specimens were primarily categorized into two distinct groups: Group 1 underwent acid etching followed by enamel bonding, while Group 2 was subjected to laser etching prior to enamel bonding. Composite bonding to the enamel surface was performed in accordance with the specific methodologies of each group. Results: Group 1 exhibited a mean shear bond strength of 49.58 MPa, in contrast to Group 2, which demonstrated a mean shear bond strength of 31.63 MPa. Subsequent statistical analysis revealed that the samples subjected to acid etching displayed a significantly higher mean shear bond strength compared to those treated with laser etching. Conclusion: The mean shear bond strength of composite was greater after acid etching as compared to composite bonded following laser etching.
