Introduction: Ceramic brackets debonding is considered a clinical challenge due to their low fracture toughness and high shear bond strength. The shear bond strength must be reduced to facilitate removal. Aim: Debonding polycrystalline ceramic brackets with Er: YAG and Er, Cr: YSGG lasers, and comparing their impacts on adhesive remnant index (ARI) and enamel surface roughness (ESR) to the traditional debonding technique. Materials & Methods: 60 polycrystalline ceramic brackets were bonded to 60 extracted premolars and divided into 3 groups: group 1(control group) contained 12 premolars that were debonded conventionally with a debonding plier, group 2: contained 24 premolars that were debonded with Er, Cr: YSGG laser and was divided into two equal subgroups: group 2A: the samples were irradiated with Er, Cr: YSGG laser at power 9 W & group 2B: the samples were irradiated with Er, Cr: YSGG laser at power 6 W, & group 3: contained 24 premolars that were debonded with Er: YAG laser and was divided into two equal subgroups: group 3A: the samples were irradiated with Er: YAG laser at power 9 W & group 3B: the samples were irradiated with Er: YAG laser at power 6 W. The debonded samples were examined using a scanning electron microscope (SEM) at 20x magnification for ARI scoring and at 60x magnification for enamel surface roughness after polishing. Results: Regarding ARI, the results showed that group 2A had the highest percentage for score 0 and group 3A for score 2, while regarding ESR, group 2B had the highest percentage for score 2. Conclusion: When compared to the traditional procedure, using Er, Cr: YSGG and Er: YAG lasers to debond polycrystalline ceramic brackets may reduce the risk of enamel damage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
