Dentin sensitivity to tooth whitening Dentin Sensitivity: C07.793.266.
Conditions
Interventions
About 40 patients with at least one third molar extraction, with dental saturation grade A3, will be selected, divided into four groups according to the use of whitening gel and desensitizing agent em
DOZ-SC - Potassium nitrate desensitizer with 16 ppm ozonated sodium fluoride without application of the whitening gel
DCC - Ozone-free sodium fluoride potassium nitrate desensitizer and bleaching gel application
and DOZ-CL - 16 ppm ozonated sodium fluoride potassium nitrate desensitizer with bleaching gel application. The office bleaching will be performed with 35% hydrogen peroxide in a single clinical sessi
O-AR: application of 16 ppm ozonated water to the surface, followed by application of the adhesive system and composite resin. The extraction of teeth will be performed 24 hours after the application
