    Introduction: The aim of this study was to evaluate, in vitro, the efficacy of bleaching in teeth with orthodontic brackets. Methods: Fifty bovine incisors were divided into 5 groups (n = 10). Group A: control (kept in artificial saliva); Group B: Opalescence Boost (38% hydrogen peroxide; Ultradent Products, USA); Group C: Power Bleaching (37% carbamide peroxide, BM4, Brazil); Group D: Opalescence Treswhite Ortho (8% hydrogen peroxide, Ultradent, Utah); and Group E: 3D White Whitestrips Oral-B (10% hydrogen peroxide, Anderson Packaging, USA). Color was measured with a spectrophotometer (Vita Easyshade, Vita Zahnfabrik, Germany) and the shade guide (Vitapan Classical, Vita Zahnfabrik, Germany). After measuring the color, brackets (Abzil Standard, Abzil, 3M) were bonded to the teeth and these submitted to bleaching. After this procedure the brackets were removed and a new color measurement was performed. Results: There was a reduction in the values of Δa and Δb, as well as an increase in ΔL. The groups B and E, showed statistically significant differences in each of the parameters evaluated with the spectrophotometer (p<0.05). With the Shade Guide, all groups showed statistically significant differences compared to the control (p<0.05). Conclusion: All bleaching agents promoted color change in the dental portion covered by the orthodontic appliance.
