Aim The aim of this study was to use surface rugosity analysis (Ra) and scanning electron microscopy (SEM) comparing effects of nano-hydroxyapatite (NANO), casein phosphopeptideamorphous calcium phosphate (CPP-ACP), and NovaMin (NOVA) on enamel's human morphology bleached with 37.5% hydrogen peroxide. Materials and methods Forty specimens (3 × 3 × 3 mm) were obtained from fully included third molars and four specimens were attached in the first molars of the volunteers. The POLApositive control has only been bleached. Three experimental groups were bleached and treated with respective bioactive: NANO, CPP-ACP, and NovaMin. The Ra analyses were performed before and after the treatment using a rugosimeter. The obtained photomicrographs were analyzed using SEM (n = 3) by three examiners, and the study was double blind. Results The Ra results were analyzed by one-way analysis of variance and Tukey's post hoc test (p < 0.05). All experimental groups showed significant differences of the others; however, the experimental groups were not significantly different from each other. Conclusion The enamel morphology of the bioactive-treated groups had more regular surfaces, than the others.
