When the whitening or bleaching procedure is anticipated, either direct or indirect tooth-colored restorative material that matches the tooth must be utilized. Therefore, the current study aimed to identify the impact of home-based bleaching agents on the surface texture of matched tooth color materials (analysis of the restorative dental biomaterial). Two types of commercially available packable and flowable resin composites were used as one of the matched tooth color materials in this study. The study was carried out on 40 specimens. The resin composites were modified as per the guidelines to measure the influence of various bleaching material concentrations on the surface roughness before and after application. A significant difference in the roughness of the surface was detected in a total between before the application of bleaching agents and after the application (101.30 ±11.32) from (7.18±4.62). It was observed that packable composite is not significantly different in roughness compared to flowable composite. The effects of bleaching agent concentration were not significantly different either. The study confirms that the adverse effect related to bleaching agents (gels) are associated with the damage of tooth-colored dental materials and the increase in roughness after the application from the baseline roughness. The flowable composites were similarly susceptible to the bleaching agents in comparison to the packable composite. The two tested different concentrations in bleaching agents. Meanwhile, the two tested resin-based composites have similar amounts of increase in surface roughness.
