Evaluation of Omnichroma and Conventional Composite Resins for Color Matching After In-Office Dental Bleaching

What this Trial Is About

This research investigates the ability of Omnichroma composite restorations to match the color of tooth structure after in-office dental bleaching. It addresses the challenge that composite restorations do not lighten with bleaching like natural teeth, which can lead to replacing restorations and potentially weakening teeth. The study tests whether single-shade resin-based composites perform similarly to conventional multi-shade composites in color matching and patient and dentist satisfaction. Participants will receive in-office bleaching treatment using hydrogen peroxide 40% with either conventional multi-shade nanohybrid composite restorations or single-shade Omnichroma composite restorations. The study is randomized with two groups comparing these materials across anterior teeth. Color measurements will be taken before and after bleaching, and satisfaction will be assessed by blinded dentists and patients. During the study, patients will have their teeth and restorations evaluated with a digital spectrophotometer and subjective assessments of color match. Follow-up visits include patient satisfaction surveys two weeks post-bleaching and color measurements over one year. Dentists will also evaluate color blending. The study involves monitoring for color match and satisfaction outcomes to assess the performance of the composites after bleaching.
