Abstract
Objective: The purpose of present study is to compare the effect of different desensitizing agents in the management of dentinal hypersensitivity after the application of in-office bleaching. Methods: This study was conducted on 27 patients complaining of tooth hypersensitivity and seeking for their teeth whitening. Gluma, Seal & Protect and Fluoride varnish desensitizing agents were used in this study then in-office bleaching was applied. The Verbal Rating Scale (VRS) was used to record scores before and after desensitization, and then was used again to record scores before and after in-office bleaching. The data compiled was statistically analyzed. Results: A remarkable reduction in dentinal hypersensitivity to both air blast and cold water stimuli was noted at the end of the application of the three desensitizing agents. However, the differences in effectiveness of the desensitizing effect after the application of the bleaching material were recorded. Conclusion: Within the limits of this study, it could be implied that for relieving hypersensitivity, all three desensitizing agents were almost equally effective, but it was concluded that the sustainability of the desensitizing effect was detected with the resin-based desensitizing agents rather than the Fluoride-based desensitizing agents.
