The aim of this study will be to evaluate topical hydrocortisone's potential to reduce/eliminate tooth sensitivity after in-office tooth bleaching. This project will be submitted to the Ethics Committee of the School of Dentistry of Araçatuba - UNESP. The clinical research studied 25 volunteers, whose ages range between 18 and 25 years. The study will also be sent to the Ethics Committee of this Institution process. The procedures will be explained to the subjects, who will give their written consent to participate. The operators will follow a split mouth design crossover of two phases. Each phase will consist of two sessions of in-office dental bleaching, with a washout period of two weeks between each phase. The factors will be the reduction/elimination of tooth sensitivity after tooth bleaching with hydrogen peroxide 38% in two levels: the topical application of a drug based hydrocortisone (Solution A) and a placebo solution (Solution B) after tooth bleaching. After a random draw, the volunteers' maxillary right or left hemi-arch will be submitted to treatment with the application of solution A while other hemi-arch will receive solution B. In the first phase, one of the maxillary hemi-arches will receive solution A and the other will receive solution B. In the second phase, the operators will reverse the sides that receive the solutions in order to conduct a crossover study. At the time of application, the operators nor the patients will know how to differentiate between such solutions, featuring a double-blind study. The experimental units are the incisors, canines and premolars of both sides. Each volunteer will be considered a statistical block. The response variable will be the degree of sensitivity after dental bleaching, measured qualitatively through each patient's report. Measuring of color alterations will be done by a device for digital...
