“COMPARATIVE EVALUATION OF DENTIN TUBULAR OCCLUSION WITH BIOACTIVE GLASS CONTAINING DENTRIFICE AND GLUMA DESENSITIZER– A SEM STUDY”
Aim: To evaluate the dentinal tubule occluding ability of two commercially available dentifrices (Gluma desensitizer and Bioactive glass) by using Scanning Electron Microscopy (SEM).
Methodology: The present study was an experimental study done upon 60 freshly extracted sound human premolars and then sectioning of the tooth was done which was further followed by ultra-sonication with distilled water. The specimens were randomly divided (20each) into 3 groups: Group 1 (distilled water only), Group 2 (Gluma Desensitizer), and Group 3 (Bioactive glass). After application of materials scanning electron microscope (SEM) examination was done. Student’s T-test was used to evaluate the effectiveness among the materials used for dentinal hypersensitivity.
Results: The present SEM study revealed that Bioactive glass was found to be more effective in occluding the dentinal tubules completely as compared to Gluma desensitizer. But Gluma Desensitizer partially occlude the dentinal tubules as compared to distilled water, which have no tendency to occlude the tubules partially.
Conclusion: It was concluded from the present study that Novamin completely occluded the dentinal tubules as compared to Gluma desensitizer and Distilled water.
