Abstract

This clinical research will be evaluating the sensitivity, the alteration and stability colors dental, on patients when submitted to in-office dental bleaching with 35% HP, without light-activation sources. According to pre-established criteria, 20 patients will be selected. The factors will be Bleaching Procedures in two levels (experimental gel based on 35% HP and placebo) and Teeth in two levels (incisors and canines). According to a randomly draw, the volunteers will be theirs superior hemiarches, right and left, submitted to placebo treatment or experimental treatment, characterizing a split-mouth design. It will be carry out four sessions of the bleaching procedures with a one week break between sessions. The response variables analysed at each session will be: Dental Color, measured previously and immediately after application of the materials and removal of absolute isolation; and Sensitivity, measured during and till 24 hours after the application of the bleaching procedures. The results obtained will be submitted to appropriate Statistical analysis.
