Abstract
Introduction: The principle of safe bracket debonding is to degrade the adhesive resin strength connecting the tooth and the bracket by softening or ablation.of adhesive resin from tooth surface without damaging the enamel. Aim: The aim of this study were to compare the efficacy of erbium yttrium aluminum garnet (Er: YAG) laser and Er Cr;YSGG in debonding on the metal brackets and determination if there are any adhesive remnants on the enamel surface by the stereomicroscope. Methods: Sixty metal brackets were bonded to sixty upper first premolars and they were divided into three groups, Group 1(control) debonded by conventional plier, group 2 debonded by Er: YAG laser and group 3 de bonded by Er Cr: YSGG. The Enamel surface were evaluated by stereo microscope for any enamel cracks and damage. Results: Er: YAG 7W laser debond the metal brackets in a shorter time than Er Cr; YSGG and Erbium Chromium Yttrium Scandium Gallium Garnet (Er Cr: YSGG) laser (6W and 7W) decreased the enamel damage compared to the Er :YAG laser and the conventional method for Debonding .Conclusion: The Er Cr; YSGG 7 W laser are clinically safer than other groups as it has acceptable chair side time in debonding and less damage on the enamel.
