A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effectiveness of Omnichroma restorations in matching the shade of teeth after in-office dental bleaching. Patients with at least two anterior restorations, one being Omnichroma and the other a conventional multi-shade composite, will be recruited. The shade matching will be assessed using a spectrophotometer before and after bleaching, with evaluations conducted by blinded dentists. Patient satisfaction regarding the color match will also be recorded two weeks post-treatment.
