Clinical evaluation of dentin hypersensitivity before and after application of desensitizing agents-An in-vivo study

This in vivo study determines whether the application of different desensitizing agents on exposed dentin surfaces was effective in reducing dentin hypersensitivity.

14 patients with 75 teeth having history of sensitivity were selected in the study. The teeth were isolated and initial sensitivity was recorded using Verbal Rating Scale (VRS) with two stimuli, probing and air stimulation. Then they were treated with following desensitizing agents Group 1-Oxa-Gel, Group 2-Seal and Protect, Group 3-Placebo Gel. Immediately after application the scores were recorded and patient was recalled after 7 days for 3 weeks.

According to paired t-test all treatments even the placebo gel were capable of reducing sensitive scores for both stimuli. There was no significant difference between all treatments.

Both the desensitizing agents were effective in reducing Dentin hypersensitivity.
