Young individuals of the same age were randomly divided into groups (G1; n=7) at-home: 8h/day/week; (G2; n=7) in-office: 4 weekly sessions of 2 applications of 15 min each one and; (G3; n=6) associated: home/office simultaneously. For at-home and in-office techniques were used carbamide peroxide 16% (WhiteGold Home/Dentsply) and hydrogen peroxide 35 % (Whitegold Office/Dentsply), respectively. The records of color were obtained by a single operator before and after bleaching using the scale Vita Bleachedguide 3D Master and digital camera Canon Rebel XT, with lighting, flash and focal distance standardized. The level of bleaching was evaluated by unit change in color scale and the number of tones achieved and change of color in the CIE L*a*b* by using the software ScanWhite®. The data were treated statistically by the nonparametric Kruskal Wallis and signs (p
