Objectives: This randomized clinical trial tested the effect of three different desensitizing agents on reduction of pain due to hypersensitive cervical dentin lesions. Materials and Methods: Twenty-eight individuals with 84 teeth diagnosed with cervical dentin hypersensitivity (DH) in at least one tooth in any three of the four quadrants were selected. Patients exhibiting pain scores of two or more on the visual analog scale (VAS) were included in the study. Each quadrant in an individual was randomly assigned to one of the three treatment groups based on computer-generated random number. The desensitizing agents used were Profluorid Varnish (Voco: Cuxhaven Germany), Admira Protect (Voco: Cuxhaven Germany), and PRG-Barrier Coat (Shofu: japan). One operator recorded the baseline sensitivity scores after evaporative and tactile stimuli by visual analog score system. The second operator who was not aware of the baseline values applied the desensitizing agents and recorded the sensitivity scores. VAS scores for both the stimuli were noted immediately after application, 1 week, and after 1 month. The data were analyzed using repeated measure ANOVA and post hoc Tukey's multiple comparison tests (P < 0.05 was considered statistically significant). Results: There was a significant reduction in VAS scores from baseline in all the three groups at all the time intervals (P < 0.001). Admira Protect showed significant reduction of hypersensitivity scores at 1 month compared to other groups (P < 0.001). Conclusion: Admira Protect was proved to be better in reducing pain due to DH than PRG-Barrier Coat and Profluorid Varnish after 1 month of application.
