Teeth sensitivity is the most popular symptom when using At-Home tooth whitening. Tri calcium phosphate containing pastes may affect the efficacy and postoperative sensitivity associated with At-Home vital tooth whitening using 20% carbamide peroxide
Subjects enrolled in this study will apply home bleaching trays with 20%carbamide peroxide 4h/day for a week, the sample will be divided into two groups : the experimental group will apply tri calcium phosphate containing paste(Clinpro) 30 min/day after bleaching treatment, the control group will apply placebo paste 30 min/day after bleaching treatment,
