As a result, functional restorations may need replacement after bleaching to match the newly whitened teeth. However, replacing a composite restoration can lead to unnecessary removal of tooth structure, potentially weakening the tooth and increasing its susceptibility to further iatrogenic damage. This study will investigate the ability of Omnichroma restorations to shade-match tooth structure after bleaching.\n\nThe null hypotheses will be:\n\n1. Single-shade RBC will not exhibit similar shade and optical behavior to conventional RBC across all anterior restorations following bleaching.\n2. Patient satisfaction regarding color blending between the restoration and tooth structure will not differ according to the type of material used.\n3. Dentist satisfaction regarding color blending between the restoration and tooth structure will not differ according to the type of material used.",[77],"Composite Resins",[79,80,81,82],"Single-shade composite","Bleaching","clinical trial","Shade matching","2025-03-19",{"date":85,"type":86},"2025-03-24","ACTUAL",{"date":88,"type":86},"2025-03-10",{"date":90,"type":71},"2026-08-01",{"name":5,"class":6},1]
