Clinical Trial Summary

This randomized, controlled, blinded clinical trial evaluated the effectiveness of different desensitizing protocols in preventing pulp inflammation after bleaching treatment with 35% hydrogen peroxide (PH) (Whiteness PH 35%).

Clinical Trial Description

Thirty healthy third human molars extracted by orthodontic indication were randomized and allocated into five groups (n = 6): CN (negative control): without intervention; CP (Positive control): PH; PMB: PH + photobiomodulation with low power laser; CPP: PH + casein phosphopeptide phosphopeptide amorphous calcium phosphate (CPP-ACPF); NANO: PH + nanohydroxyapatite. The office whitening was performed in two sessions with a single application of 45 min and an interval of 48 hours between them. Pulp tissues were removed for immunohistochemical analysis. Immunostaining was performed for Caspase 3 using an Axio Scope.A1 microscope. ;
