Popis:	This study aimed to evaluate whether tooth enamel bleached with hydrogen peroxide (HEnamel blocks were prepared from human molars, and submitted to surface microhardness analysis (baseline). Blocks were prepared and randomly divided into four treatment groups (n = 20): G1 and G2-bleached with 7.5% HG2 showed the highest %SHL after bleaching. G1 presented the lowest %SHL in comparison with G2, G3, G4, and G6 after erosion (p 0.05), which was confirmed only by the SEM analysis.It is suggested that low concentration of HLow concentration of H
