Abstract

Introduction: Because adults often request more esthetic ceramic brackets, it is important to conduct a study with aim of evaluating mean shear bond strength (BS) of ceramic brackets on sandblasted versus diamond bur roughened amalgam surfaces.

Material and methods: This In-Vitro, Comparative study involved 60 extracted human maxillary molars randomly divided into 2 groups. In group-I ceramic brackets were bonded to amalgam using sandblasting with 50 Î¼m alumina particles. In group-II, brackets were bonded after roughening the amalgam surface with diamond bur. Mean BS was measured using universal testing machine.

Results: BS of ceramic brackets bonded with sandblasting was significantly higher than diamond bur roughened group.

Conclusions: Amalgam surface treatment with sandblasting increased shear bond strength of ceramic brackets.
