    Dental discoloration has been a longstanding concern for many individuals. However, various methods and agents, such as hydrogen peroxide (HP) and carbamide peroxide (CP), applied either at home or in a dental office, have emerged in dental practice to improve aesthetics. It is essential to consider how these applications may have positive or negative effects on patients. This study aimed to determine the degree of staining in dental structures subjected to different types of dental bleaching over 48 hours. The research was experimental, in vitro, and prospective. The study used 10% carbamide peroxide (CP10), 22% carbamide peroxide (CP22), 35% hydrogen peroxide (HP35), and a control group (CG) not exposed to any bleaching agent, totaling 40 experimental samples (n = 40) divided into groups of 10 test bodies each. The degree of staining in dental structures subjected to different types of bleaching was assessed using a Vita EasyShade Advance 4.0 spectrophotometer over 48 hours. Conclusions: Dental structures exposed to 10% carbamide peroxide exhibited the highest degree of staining, with darker coloration compared to the initial baseline prior to bleaching. Structures exposed to 22% carbamide peroxide showed the lowest degree of staining, retaining a lighter tone compared to the initial baseline. Structures treated with hydrogen peroxide exhibited a moderate degree of staining, with a slightly duller coloration compared to their initial and final color measurements.
