Contribution of a* to Dental Bleaching After Combined Dental Bleaching
Sponsor: University of Valencia
Summary
A prospective, non-randomized, single-arm interventional clinical study with a before-after design will be conducted to assess changes in CIELab color parameters and the Whiteness Index for Dentistry (WID) following a standardized combined dental bleaching protocol. The study aims to evaluate the contribution of the a\* parameter (green-red axis) to overall dental whiteness.

Combined Dental Bleaching
The intervention consists of an in-office bleaching phase with two 20-minute applications of 40% hydrogen peroxide, followed by an at-home bleaching phase using 16% carbamide peroxide applied with custom trays for 90 minutes daily. Treatment will continue until color stabilization is achieved, defined as a change in WID of less than 2.6 units between two consecutive weekly measurements.
