AN IN VITRO COMPARATIVE EVALUATION OF DENTINAL TUBULE OCCLUSION BY CURRENT DESENSITIZING AGENTS- A SCANNING ELECTRON MICROSCOPIC STUDY
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2019, Vol 8, Issue 4
Abstract
BACKGROUND Increasing life expectancy coupled with effective treatment options for dental caries and periodontal disease has enabled patients to retain their natural teeth for prolonged periods. Dentinal hypersensitivity is a very common clinical problem affecting the adult population. Aims and Objectives- The aim of the present study was to compare the effects of topical application of three commercially available desensitizing products: nano-hydroxyapatite (Aclaim), Pro-Argin (Colgate Sensitive Pro-relief) and sodium fluoride with functionalized tricalcium phosphate (Clinpro) on dentinal tubule occlusion. MATERIALS AND METHODS Extracted human premolars were cut longitudinal to the tooth axis with a diamond disk and polished to obtain a flat surface with cleanly exposed dentinal tubules. Then the dentin samples were kept in a demineralising solution (Citric acid) for 40 mins. The teeth were randomly divided into three groups (n=10), according to the dentin surface treatments: Group A- Aclaim (Nanohydroxyapatite); Group B- Colgate Sensitive Pro-relief (Pro-Argin); Group C – Clinpro (NaF with functionalized tricalcium phosphate). Brushings were done for 15 secs. twice daily for 1 week. In between all the samples were stored in artificial saliva. Then the samples were dried and observed under SEM. RESULTS The dentin desensitizing agents tested showed a wide range of dentinal tubule occlusion under SEM examination. Occlusion of dentinal tubules by Pro-Argin was comparatively superior to the other two agents. CONCLUSION The present study provides an understanding regarding the potential occluding effects of three desensitizing agents. It also explains the mechanisms of dentinal tubule occlusion by these three agents which may probably explain the reasons for varying results while treating dentinal hypersensitivity with these agents.
