Evaluation of dentinal tubule occlusion by 10% Strontium chloride: An SEM study
Journal Title: Journal of Medical and Dental Science Research (Quest Journals JMDSR) - Year 2019, Vol 6, Issue 1
Abstract
Aim–The aim of this study was to evaluate the dentinal tubule occluding ability of 10% Strontium chloride containing desensitizing dentifrices using scanning electron microscope. Methods – Forty-five 1mm thick dentine discs were obtained from orthodontically extracted human premolar teeth. Each disc was then split into two halves. One half was allotted to Group-1 (Control group) and the other half was allotted to Group-2 (Test group). GROUP 1: brushed without dentifrices. GROUP 2: brushed with dentifrices containing 10% Strontium chloride hexahydrate. After brushing for 2 minutes twice a day, the specimens were stored in artificial saliva. Specimens were analyzed after 7 days under SEM. Results – The 10% strontium chloride containing desensitizing agent significantly resulted in effective dentinal tubule occlusion. 45.28% of the dentinal tubules showed complete dentinal tubule occlusion, 11.26% showed partial occlusion and 43.46% remained unoccluded. Conclusion -. The inclusion of 10% strontium chloride into a toothpaste formulation may be an effective approach to treat dentinal hypersensitivity as it showed high percentage of dentinal tubule occlusion
