Figure 1: Dentin surface submitted to bleaching with 35% hydrogen peroxide and posttreatment with 10% sodium ascorbate solution at different protocols. (a) without bleaching and posttreatment (positive control)-homogeneous smear layer covering the surface; (b) bleached and without posttreatment (negative control)-fissures in the surface probably derived from the high-concentrated bleaching agent; (c) bleached and treated with sodium ascorbate at protocol 1-Fissures, smear layer, and some residual granules from solution; (d) bleached and treated with SA at Protocol 2-smear layer and some residual granules from solution and (e) bleached and treated with sodium ascorbate at Protocol 3-smear layer and larger amount of residual granules from solution
