The objective of this research was to compare in vitro the changes in the surface roughness of the tooth structure, generated by different bleaching agents containing hydrogen peroxide (HP). The study detected 50 specimens obtained from bovine teeth, sectioned into dental blocks (7 mm x 7 mm x 7 mm) and prepared to perform an initial reading of surface roughness (Ra), using a profilometer. The samples were randomly divided into 5 groups (n= 10) according to the whitening agent to which they were exposed: group 1: Whiteness HP Maxx 35%, group 2: Opalescent Boost 40% HP, group 3: Opalescent Go 10% HP, group 4: Whiteness Perfect with 10% carbamide peroxide (CP) as positive control and group 5: negative control, with physiological saline. At the end of the bleaching stage, the samples were kept in physiological saline solution; Finally, some profilometric measurements were performed to determine the postbleaching surface roughness parameters. The SPSS® 27.0 statistical package was used for statistical analysis. To identify whether the data follow a normal distribution, the Shapiro Wilk test was used (p > 0.05), then the non-parametric Wilcoxon test was applied for related samples (Initial – final). It is concluded that when applying the different whitening agents containing hydrogen peroxide, no statistically significant differences were found between the groups; however, all experimental groups presented differences before and after the application of the whitening agents.
