Comparative evaluation of the efficacy of the desensitizing and remineralizing agent in the reduction of dentin hypersensitivity after orthodontic debonding - a randomized clinical trial.

Abstract

IntroductionEnamel loss is a common problem during various orthodontic procedures. The study aims to compare the efficacy of a desensitizer and remineralizer in the reduction of the dentin hypersensitivity (DH) associated with enamel microcracks after orthodontic debonding.MethodsA unicentric two arm parallel study with 30 subjects randomly assigned to each groups following debonding. Group-1 subjects were treated with Gluma® desensitizer (5% glutaraldehyde and 35% hydroxyethyl methacrylate (HEMA)) and the Group-2 intervention included a remineralizing agent GC Tooth Mousse Plus® (casein phospho peptide and amorphous calcium Fluro phosphate (CPP:ACFP)). The Visual Analogue Scale (VAS) was utilized to evaluate DH as subjective perception of pain following the Air blast test and Cold test. The VAS scale was indexed from 0–10 markings based on the intensity of perception. Five different time points T0 and T1 - immediately after debonding and intervention on day 1, T2 – 48 hours, and T3 after 72 hours were taken for the assessment of VAS scores.ResultsThe VAS scores for the airblast test for group 1 were (2.73, 0, 0.06, 0.03) and group 2 (2.46, 0, 0.16, 0.13) at different periods. The sensitivity scores for the cold blast test for group 1 were (2.73, 0, 0.13, 0.03) and for group 2 (2.46, 0, 0.16, 0.13). There was 98 percent reduction in DH between T0 and T3 and was statistically significant (p<0.05) for both the groups.ConclusionGluma® desensitizer and GC Tooth Mousse Plus® are equally effective in the reduction of DH in the orthodontic patient following debonding.
