Effect of Laser and Potassium Nitrate Application on the Sensitivity Control in Bleached Teeth

Dentin Sensitivity Clinical Trial

Official title:
Effect of Low-level Light Therapy Associated With Potassium Nitrate in the Control of Post-bleaching Dental Sensitivity: a Randomized, Double-blind, Split-mouth, Controlled Trial

Clinical Trial Summary

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

Clinical Trial Description

The objective of this double blind, randomized and controlled clinical study, was to evaluate the efficacy of potassium nitrate / sodium fluoride (KNO3 / KF) gel associated with LLLT (Low Level Light Therapy) on teeth that were exposed to 35% hydrogen peroxide during 3 weeks of bleaching treatment. Methods: 50 volunteers were evaluated through the split-mouth model, where the hemiarcates were randomized and later allocated in one of the experimental groups: G1 (negative control)- group with no desensitizing treatment, only bleached; G2 (positive control)- group treated with LLLT + placebo gel; G3- group treated with placebo laser application + 5% KNO3 / 2% KF gel; and G4- group treated with LLLT + 5% KNO3 / 2% KF gel. ;
