Effect of topical application of Hydrocortisone drops on dental hypersensitivity after bleaching, a clinical study.
Bleaching gel containing hydrogen peroxide (H2O2) cause inflammation in pulp tissue and many studies have verified the presence of neuropeptides such as substance P (SP) and calcitonin gene-related peptide (CGRP). On the other hand, the topical application hydrocortisone reduce this pulp inflammation after dental bleaching. In our study we will compare the effect of hydrocortisone to a placebo gel on dental hypersensitivity after dental bleaching using a thermic, an electric test and the visual analogue scale. After each bleaching session (2 sessions), hydrocortisone drops will be applied randomly on one side of the arch and the placebo on the other side, they will be held for 10 mins, then we'll remove them and assess the pain by stimulating each tooth with thermal and electrical stimulus. We will do these pain assessments 10 mins after the dental bleaching, 24h and 48 hours.Titulaire :
