Abstract: Objective: To evaluate the shear bond strength of metallic brackets bonded with Right-On composite under different enamel conditions. Materials and methods: Forty-five bovine permanent lower incisors were used, and were divided into three groups (n = 15). For group 1 (control), the bonding procedures were performed by using Transbond XT according to the manufacturer's recommendations, that is 37% phosphoric acid etching, washing, drying, application of primer XT and, finally, the bonding procedure itself. For the other two groups, the brackets were bonded by using the Right-On composite. The bonding procedures for group 2 were performed according to the manufacturer's recommendations, that is 37% phosphoric acid etching, application of the composite activation liquid, both on the etched surface and the bracket's base, and insertion of the composite on the bracket's base and bracket positioning. In group 3, the dental surface was etched by using Transbond Plus Self-Etching Primer, and the composite activator liquid was applied on the bracket's base only. Following the bonding procedures, the shear bond strength test was performed by using an Instron machine at the speed of 0.5mm/min. for mechanical tests. Results and conclusion: Results showed no statistical differences between groups 1 and 2 (p > 0.05). However, both groups were statistically superior to group 3 (p < 0.05). A greater number of fractures on the bracket/composite interface was evidenced by the ARI results.
