Efficacy of Nano Crystallised Calcium Phosphate (NCCP) and Casein Phosphopeptide – Amorphous Calcium Phosphate (CPP-ACP) for Controlling Postoperative Sensitivity After Power Bleaching-A Comparative In-Vivo Study

Abstract

Tooth bleaching is one of the most popular cosmetic dental procedures opted by the patients who desire pleasing smile. It is the simplest, least invasive means available to lighten discolored vital teeth. A number of desensitizing agents have been tried in an attempt to counteract bleaching-related sensitivity. This study was done to compare the effect of two different desensitizing agents for controlling post operative sensitivity after power bleach procedure. Sixty volunteers with mild to moderate dental fluorosis in maxillary anterior teeth, who fulfilled the inclusion and exclusion criteria, were randomly selected for this study. After the bleaching procedurea demo was given to the patient while application of desensitising gel and was instructed to use the gel for 14 days.All the patients were recalled at an interval of 1^st day, 3^rdday, 5^th day, 7^th day, and on 14^th day to record the post operative sensitivity after power bleach procedure. The observations were analyzed using one way analysis of variance (ANOVA), Tukeys post hoc test. On the basis of VAS results, all the groups showed post operative sensitivity of varied intensity at different intervals. NCCP showed less sensitivity followed by CPP-ACP and Control group.
