Abstract
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.
Highlights
Dentin Hypersensitivity (DH) has been defined as brief, sharp, acute pain originating from exposed dentin in response to different stimuli such as thermal, tactile, osmotic, chemical or evaporative stimuli that cannot be attributed to any other dental pathology [1, 2]
A total of nine participants were lost to follow-up, 4 in the Sylc group and 5 in the BiFlourid 10 group
Sylc application using air polishing showed a significant reduction in pain caused by DH compared to fluoride varnish application in all test stimuli after 3 weeks and up to 1 year post-intervention
Summary
Dentin Hypersensitivity (DH) has been defined as brief, sharp, acute pain originating from exposed dentin in response to different stimuli such as thermal, tactile, osmotic, chemical or evaporative stimuli that cannot be attributed to any other dental pathology [1, 2]. The hydrodynamic theory explained the cause of DH as stimuli acting on an exposed surface, causing movement of dentinal fluid, thereby activating nerve endings in the pulp. The. Several approaches to DH treatment were proposed to interfere, whether transiently or permanently, with the hydrodynamic theory. Several approaches to DH treatment were proposed to interfere, whether transiently or permanently, with the hydrodynamic theory These approaches include root coverage and the use of lasers, ions, dentinal sealants, and occluding and nerve depolarization agents, chosen according to the primary cause [6]. There are two major strategies in managing DH; the first is nerve desensitization, and the second is the physical
