Summary

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

Detailed description

The objective of this double blind, randomized and controlled clinical study, was to evaluate the efficacy of 1.1% sodium fluoride associated with LLLT (Low Level Laser Therapy) on teeth that were exposed to 35% hydrogen peroxide during 4 weeks of bleaching treatment. Methods: 25 volunteers were evaluated through the split-mouth model, where the hemiarcates were ranzomized and later allocated in one of the experimental groups: G-FLUOR+LASER - constitutes the group treated with LLLT + 1.1% sodium fluoride; and G-FLUOR - constitutes the group treated with placebo + 1.1% sodium fluoride .

Conditions

• Dentin Sensitivity

Interventions

Type	Name	Description
DEVICE	Low Level Laser Therapy	Laser therapy: it was used the infrared spectrum with wavelength of 808 nm in its active environment AsGaAl, in two points: cervical and central-medial region of the incisors, canines and premolars.
DRUG	1.1% Sodium Fluoride	Fluoride therapy: 1.1% sodium fluoride 5000 ppm was applied for 5 minutes on the vestibular surface of all pre-bleached dental elements.
DRUG	In-office dental bleaching	Both groups received the in-office bleaching treatment. Three 15-minute applications of the 35% hydrogen peroxide gel were performed, totaling 45 minutes in each of the 4 sessions, with a 7-day interval.
