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.

Detailed description

The experimental design will follow the consolidated standards for test reports (CONSORT). After approval by the Ethics Committee for Research duly registered, the trial will be conducted in the clinic of dental school at the Federal Fluminense University located in Nova Friburgo.Every Health Institute participants will be informed about the nature and objectives of the study.It will be one test study Clinical randomized, parallel, triple-blind, used to measure the level of tooth sensitivity 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.

After 7 days (one week), the same protocol will be held for the second and final practice session office bleaching.

Interventions

Type	Name	Description
DRUG	Dexamethasone acetate	The volunteers in the Dexamethasone acetate group (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 two days before the first clinical session whitening; 8 mg (1 capsule) the 9 am to 1 day before session whitening, 8 mg (1 capsule) to 9 am on the day of the first session of whitening.Clinical intervention: 1- Dry teeth and apply Gingival Barrier to both arches. 2- Light cure. 3- Firmly attach a mixing nozzle to the Pola Office+. 4- Apply a thin layer of gel to all teeth undergoing treatment. 5- Leave gel on for 8 minutes. 6- Suction it off. 7- Repeat steps 5-6 twice times. 8- After the last application, suction all the gel off, then wash and apply suction. 9- Remove Gingival Barrier. 10- A placebo gel will be applied with a brush on the labial surface of the teeth whitened for 2 to 3 minutes .
DRUG	Potassium Nitrate	The volunteers in the Potassium Nitrate Group (Placebo group) will receive 6 placebo capsules, who contained the same components of de dexamethasone drug except the active ingredient (starch \[50%\], lactose monohydrate \[35%\], dibasic calcium phosphate \[14%\], and magnesium stearate \[1%\]).Clinical session:1- Dry teeth and apply Gingival Barrier to both arches. 2- Light cure. 3- Firmly attach a mixing nozzle to the Pola Office+. 4- Apply a thin layer of gel to all teeth undergoing treatment. 5- Leave gel on for 8 minutes. 6- Suction it off. 7- Repeat steps 5-6 twice times. 8- After the last application, suction all the gel off, then wash and apply suction. 9- Remove Gingival Barrier. 10- A desensitizing gel containing 6% potassium nitrate will be applied with a brush on the labial surface of the teeth whitened for 2 to 3 minutes .
