Anti-inflammatory Steroids in the Prevention of Tooth Sensitivity

Summary

Clinical randomized, triple-blind, used to measure the level of tooth sensitivity on volunteers using a modified virtual analog scale (VAS). Sixty-six volunteers will be selected and recruited, following inclusion criteria and pre-established exclusion. All volunteers will be guided and sign a term of clarification and consent. Volunteers will be randomly divided into two groups: the control group to receive placebo capsules and application of desensitizing gel containing 6% potassium nitrate and 0.10% fluoro- (conventional treatment) and the experimental group will receive the anti-inflammatory corticosteroids (dexamethasone, capsule - 8mg) and application of a placebo gel. Patients will be treated in two clinical sessions with an interval of 7 days (one week) between them. The protocol for use of the product is as follows: The volunteers in the experimental group will receive six capsules of dexamethasone 8 mg each to be administered orally, initially two days before the first bleaching query as follows: 8 mg (1 capsule) 9 am in the morning two days before the first clinical session whitening; 8 mg (1 capsule) the 9 am to 1 day before the first practice session whitening, 8 mg (1 capsule) to 9 am on the day of the first practice session of whitening. After 7 days (one week), the same protocol will be held for the second and final practice session office bleaching.
