OBJECTIVE: This study evaluated the color match of restorations made with single-shade composites following two protocols of tooth bleaching. MATERIALS AND METHODS: Cavities in the cervical third of bovine crowns were restored using single-shade composites (Omnichroma or Vittra Unique) or a multi-shade composite restoration strategy (Filtek Z350 XT). The color of both the restoration and the middle third of the unrestored tooth were recorded. The Whiteness Index for Dentistry (WID) and color differences (ΔE RESULTS: Bleaching protocols did not significantly affect WID or ΔE CONCLUSION: Tooth bleaching protocols differentially affected the color match of restorations made using single-shade composites compared to multi-shade restorations. CLINICAL RELEVANCE: Tooth bleaching protocols have a limited effect on the color of composites but can influence the color match between the restoration and the surrounding enamel. Specifically, color mismatches tend to decrease for lighter materials, such as single-shade composites, after tooth bleaching, improving the overall esthetic integration of the restoration with the natural tooth structure.
