Objective: To determine the effectiveness of Sylc (a bioactive glass-based powder) delivered by an air polishing system compared to fluoride varnish application in managing Dentin Hypersensitivity (DH). Methods: This study was a double-blinded randomized clinical trial where 50 participants with DH in at least one tooth with a non-carious cervical lesion were included and randomized into two groups (25 participants each) to receive either Sylc air polishing or fluoride varnish application. Baseline and post-intervention measurements of pain were carried out using evaporative, thermal and tactile stimuli using a modified visual analog scale at 3 minutes, 1, 2, 3and 4 weeks, 6 months and 1 year post-intervention. Data for pain intensity was recorded and analyzed for each group. Results: For the three stimuli used, Sylc air polishing showed statistically significant reduction of pain intensity (P<0.05) after 3 weeks and up to 1 year post-intervention. Fluoride varnish application showed a statistically significant reduction of pain intensity in evaporative and thermal stimuli at 1 week post-intervention only. Conclusion: Sylc air polishing was effective in relieving pain due to DH after 3 weeks and up to 1 year post-intervention, which showed that it can be used as a long-term treatment for DH.
