Objectives: To test the shear bond strength of brackets bonded to enamel etched with Erbium: Yttrium-aluminium-garnet laser (Er YAG) at different power outputs of 1, 2, and 2.5 W and to check the surface characteristics of enamel using scanning electron microscope. Materials and Methods: Human premolars that had been extracted for orthodontic reason were used. Enamel was then etched using conventional acid etch technique and Er:YAG laser at three different power outputs. Few teeth did not undergo shear test but prepared for scanning electron microscope (SEM) evaluation. Results: The shear bond strength associated with the 1 W laser irradiation was significantly less than the strengths obtained with the other groups. Both the 2 and 2.5 W laser irradiations were capable of etching enamel in the same manner like with acid etching. Conclusion: The mean shear bond strength and enamel surface etching obtained with an Er:YAG laser is comparable to that obtained with acid etching and an alternate to acid etching. |
