Objective To evaluate the color change and tooth whitening perception in 2 and 3 mm dental specimens simulating the orthodontic bracket for a 14‐day period. Materials and methods Forty bovine tooth fragments (8 × 7 mm) of 2 mm (G2, n = 20) and 3 mm (G3, n = 20) were divided into Control (C: without bracket simulation and whitening) and Experimental (E: with composite resin simulating orthodontic bracket cementation area). Analyses of color change (ΔE 00 ) and perception of tooth whitening (WI D ) were performed before (T 0 ) and after (T 1 ) the first bleaching session; before (T 2 ) and after (T 3 ) the second bleaching session; and after 7 days of the second bleaching session (T 4 ). Results After 14 days (T4), ΔE 00 and WI D showed similarity results, except for G2C and G3E . The thickness did not influence the ΔE 00 and WI D (G2C = G3C and G2E = G3E). The presence of orthodontic bracket did not interfere in the color change or tooth whitening perception after 14 days, except for comparison of G2C and G3E. Additionally, dentin thickness did not influence the color change. Clinical significance Teeth with orthodontic brackets showed similar color change and whitening perception to teeth without orthodontic bracket, but it is not influenced by dentin thickness.
