Background: Hypersensitivity is the common clinical condition with multi etiological factors that may cause discomfort to the patients. The condition may affect the patient from establishing or maintaining adequate oral hygiene measures which may further complicate oral health. Many desensitizing agents have been launched in market in different forms attempting to overcome such a problem. The purpose of this study was to evaluate the ability of new desensitizing agent to occlude dentinal tubule and reduce their diameter as measured by Scanning Electron Microscope.

Materials and Methods: 15 sound maxillary premolars were extracted. Samples were sectioned mesiodistally to obtain 15 buccal and 15 lingual surfaces, and enamel was removed in order to simulate hypersensitive dentin. Specimens were randomly divided into four groups. Group 1: 5 samples were coated with Gluma desensitizer, Group 2: 5 samples were coated with VivaSens, Group 3: 5 samples were coated with MS Coat, Group 4: 5 samples each of the contralateral parts of samples on which no desensitizing agent was applied, which acted as the controls. All the specimens were examined under SEM and photomicrographs were evaluated to assess the opening of dentinal tubules in the controls and occlusion of dentinal tubules in their contralateral parts coated with the desensitizing agents.

Results: Intra-group comparison revealed statistically significant amount of tubules got occluded after the application of MS Coat desensitizer (Group-3) as compared to tubules that got occluded after the application of VivaSens desensitizer (Group-2) and Gluma desensitizer (Group-1).

Conclusion: In present study, MS Coat (Group-3) was found to produce more com­pletely occluded tubules while Viva Sens (Group-2) followed by Gluma desensitizer (Group-1) creating more partial occlusion on application.
