Evaluating color-adjusting composite resin after dental bleaching
Clinical Evaluation of a Single-Shade, Color-Adjusting Composite Resin Following In-Office Dental Bleaching: A Randomized Clinical Trial
This study is testing if a new type of dental filling can better match the color of teeth after they’ve been bleached, and it’s for patients who already have some dental work done.

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.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older with at least two anterior restorations, one of which is an Omnichroma restoration.
Not a fit: Patients with severe bruxism, non-vital teeth, or significant tooth discoloration may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance aesthetic outcomes for patients undergoing dental bleaching by reducing the need for restoration replacements.
How similar studies have performed: While the approach of using color-adjusting composites is innovative, similar studies have not been widely reported, making this a novel investigation.
