Summary

Bleaching protocol In each session, volunteers received prophylaxis with pumice powder and water. Then, gingival tissue was protected using a light-cured resin gum barrier applied according to the manufacturer's instructions (Lase Protect - DMC, São Carlos, SP, Brazil). Both bleaching agents were prepared by mixing hydrogen peroxide and thickening compounds according to the manufacturer's instructions (with 3 peroxide drops for 1 drop of thickener). The resultant gels were distributed uniformly on the upper hemiarcade surfaces of the teeth. A total of 8 teeth between the first premolars were bleached for each patient. In each bleaching session, the bleaching gels were applied twice for 12 minutes each. In each application, the surface of the gel was light activated with continuous irradiance for 12 minutes using LED/laser light with a total power of 1800 mW (Whitening Lase Plus - DMC Equipamentos, São Carlos, SP, Brazil). Three bleaching sessions were completed for the patients, and the interval between sessions was 7 days
