Summary

To investigate the effects of desensitizing agents on the dental bleaching process, testing the hypothesis that they may control dental sensitivity.

Conditions

  • Dentin Sensitivity

Interventions

DRUG

In-office dental bleaching

The group will receive in-office bleaching treatment. Three 15-minute applications of the 35% hydrogen peroxide gel were performed, totaling 45 minutes in each of the 3 sessions, with a 7-day interval.

DRUG

Low Level Laser Therapy

It will be used the infrared spectrum with wavelength of 808 nm in its active environment AsGaAl, in two points: cervical and apical region of the incisors, canines and premolars.

DRUG

5% potassium nitrate / 2% sodium fluoride gel

5% potassium nitrate / 2% sodium fluoride gel will be applied for 10 minutes on the vestibular surface of all pre-bleached dental elements, following the manufacturer's protocol.
