The Efficiency of 10% Carbamide Peroxide Gel on Dental Enamel
Dental Materials Journal, 2004 This study investigated the effect of 10% carbamide peroxide gel on human tooth color, vibrational mode, and mineral loss. The exposed enamels were bleached for two weeks (six hours' bleaching and 18 hours' storage in distilled water per day). Color change was calculated from the CIE L*a*b* color values.
