ABSTRACT Background: Several studies have been published about the effect of carbamide peroxide on enamel surface morphology. However, only a few carried out under intraoral conditions. The purpose this study was to investigate two commercially available 10% bleaching products (Colgate Platinum and Starbrite) morphology Materials Methods: Twenty‐four subjects were divided into groups assigned product use for 2 weeks. Epoxy resin replicas obtained from maxillary right central incisors before, immediately after, 3 months after procedure examined scanning electron microscope. Results: Immediately procedure, porosity had increased in Colgate group, whereas erosive alterations observed Starbrite group. At months, group similar untreated surface. In defects decreased within appearance almost same as enamel. Conclusion: Even though both agents caused enamel, these reversed following treatment. CLINICAL SIGNIFICANCE results suggest that cause bleaching, degree depends brand agent duration application time. revert normal months.
