Abstract: (327 Views)

Currently, a growing request in the field of aesthetics is perceptible. Accordingly, tooth lightening and bleaching are among the conventional measures used to increase dental aesthetics and decrease tooth discoloration complications without the struggle of tooth preparation. However, the color of composite resin materials changes during the bleaching process. Therefore, this study is a narrative review of the literature related to the effects of tooth whitening on composite resin restorations and the degree of bleaching agent effects on natural teeth in comparison to their effects on restorative teeth. For this reason, the associated keywords were selected as the points of departure. An electronic search was performed through MEDLINE/PubMed, Scopus, and ISI Web of Science until May 2025. A separate search was subsequently performed via the Google search engine. A total of 146 articles were subsequently identified after the initial search and evaluated on the basis of the influence of at-home bleaching and at-office bleaching, as well as the effects of different bleaching agent concentrations on color change. According to these studies, composite resins such as a silorane-based Ormocer-based nanohybrid after high-concentration hydrogen peroxide (40%) treatment under the office bleaching regimen resulted in overall greater color change. Finally, more meta-analytical and scientometric studies are needed to identify the influencing factors related to color variation in restorative teeth.

Keywords: Dentistry, Composite Resins, Tooth Discoloration, Tooth Bleaching, Hydrogen Peroxide
