%X When planning a whitening or bleaching procedure, it is essential to use either indirect or direct tooth-colored restorative materials that closely match the natural tooth shade. This study aimed to investigate the effects of home bleaching agents on the surface texture of these materials, specifically focusing on restorative dental biomaterials. Two types of commercially available resin composites, packable and flowable, were selected as the tooth-colored materials under investigation. A total of 40 specimens were prepared following standard protocols to evaluate the effect of different concentrations of bleaching agents on surface roughness before and after treatment. A statistically significant increase in surface roughness was observed, with values increasing from 7.18 ± 4.62 to 101.30 ± 11.32 after the use of bleaching agents. However, no significant difference was found between the roughness of packable and flowable composites. Similarly, variations in bleaching agent concentration did not produce a statistically significant effect. The findings indicate that bleaching agents contribute to the degradation of tooth-colored restorative materials, leading to increased surface roughness after treatment compared to baseline levels. The flowable composites showed a similar susceptibility to bleaching effects as the packable composites. Regardless of concentration, both tested bleaching agents caused comparable increases in surface roughness in the resin-based composites.
