Abstract

Aim: The aim of this study was to measure the level of postoperative sensitivity after two in-office whitening treatments. Materials and Methods: Twenty-two patients, divided in two groups of 11, took part in this study and they voluntarily agreed to a bleaching treatment. Two different in-office bleaching agents were used: Zoom2, based on 25% hydrogen peroxide and initialized by the light source from the same manufacturer, and Opalescence Boost, based on 38% hydrogen peroxide without the light initiation. The pain was evaluated by the visual analogue scale (VAS) and the data were recorded immediately, and at 6 and 24 hours after bleaching. Results: The data were analyzed by Wilcoxon Signed Rank Test. The difference between postoperative sensitivity after application of Zoom2 and Boost whitening agents, measured immediately after the treatment, 6
and 24 hours after bleaching, was not statistically significant (p>0.05). Both whitening treatments show the same prevalence of postoperative sensitivity, which was the highest immediately after
the treatment and 6 hours later (p<0.05). Both agents show obvious appearance of postoperative sensitivity, which decreases to the values measured 24 hours after the treatment. Conclusion: The
postoperative pain and sensitivity during and after both in-office whitening treatment agents with different hydrogen peroxide concentrations occur as one of the possible side-effects which were
the highest immediately after the treatment and 6 hours later, and then decreasing to the values measured 24 hours after the treatment.
