Effect of bleaching gel volume on color change and postoperative sensitivity: a randomized clinical study.

Objectives: Although bleaching therapy is considered a dose-dependent treatment, the effect of the volume of product used is yet to be studied. This study thus aimed to evaluate the influence of bleaching gel volume on chromatic alteration and postoperative sensitivity.

Methodology: Thirty patients were selected and allocated into three groups; the lower canines were analyzed according to the volume of gel used: GI-0.
