Enamel surface roughness in young permanent tooth after bleaching
Bleaching for children is rarely performed in dental clinic, but the literature indicates that bleaching is used for children. Bleaching causes demineralization that can increase enamel surface roughness. However, the addition of fluoride and potassium nitarte can inhibit mineral loss and activate r...

Bleaching for children is rarely performed in dental clinic, but the literature indicates that bleaching is used for children. Bleaching causes demineralization that can increase enamel surface roughness. However, the addition of fluoride and potassium nitarte can inhibit mineral loss and activate remineralization. The aim of this in vitro study is to evaluate the surface roughness of young permanent tooth enamel submitted to bleaching with 10% carbamide peroxide and 10% carbamide peroxide containing potassium nitrate and fluoride. Materials and Methods: fourteen dental blocks (5x5mm2) from young permanent teeth (premolar) with polished enamel surface were randomly assigned to 2 treatment group (n=7), as follows: 10% CP (Group 1) and 10% CP+PF (Group II).
