This randomized clinical trial will evaluate the effect of an experimental gel containing andiroba oil (Carapa guianensis) in reducing postoperative tooth sensitivity caused by bleaching with 35% hydrogen peroxide. Volunteers in this study will be randomized into 3 different groups - PG (placebo gel), KF2G (potassium nitrate gel) and AG (andiroba gel). Groups KF2G and AG will receive treatment with potassium nitrate desensitizing gel and the experimental andiroba gel, respectively. This will be applied to the buccal surfaces of the central incisors, lateral incisors, canines and upper and lower premolars, with a rubber cup in an active manner, for 10 minutes. Group GP will receive the application of a placebo gel (without active ingredient), under the same conditions described for the other groups. Subsequently, all groups will undergo in-office bleaching treatment with 35% hydrogen peroxide. Post-bleaching sensitivity will be collected using a form consisting of the visual analogue scale (VAS). Color measurement will be performed with a spectrophotometer at two times: baseline (T0) and one week after the 3rd bleaching session (T1).
