| Summary: | Summary:
Objective: to evaluate dental enamel surface alterations after bleaching treatments with Hydrogen
peroxide and Fluoride. Methods: Extracted pre-molars were analys under SEM after bleaching
treatment; the samples were storaged in saline solution. Two phases were made, without and with
fluoride application after bleaching treatment using Nitewhite® and Zoom2® as bleaching agents, the
shade was taken at baseline and after the bleaching procedure. Results: 36.6% of samples showed
moderate alterations and 32.9% showed severe enamel alterations. Post/treatment with fluoride showed
variable outcomes, but mild alterations in the fluoride/treated samples were found to be more
frequent, A statistically significant result was found among fluoride/treated and non/treated groups
after bleaching (P<0.005) chisquare test. In contrast, within fluoride/treated groups it was not
found significant differences. Conclusions: The use of high concentrated in/office carbamide
peroxide may require limited application sessions as recommended by the manufacturer. The use of
post/treatment fluoride may bring great benefit to patient’s dental hypersensitivity. Key words:
Carbamide Peroxide. Hydrogen Peroxide. Enamel roughness. Fluoride. Remineralization.
