EVALUATION OF THE EFFECTIVENESS OF DESENSITIZING DENTIFRICE- FLURO CALCIUM PHOSPHO SILICATE AND DENTAL LASER ON DENTINAL TUBULE OCCLUSION- AN INVTRO –SEM STUDY

Abstract

Background: the present study aims to evaluate whether fluoro calcium phospho silicate(Biomin or Elzenes) or in combination with Diode laser has better dentinal tubule occlusion and can be suggested as a effective treatment modality for patients with dentinal hypersensitivity. In study setting, SEM analysis was done at Sophisticated test and instrumentation centre, Cochin University of Science and Technology (CUSAT), Kerala. 80 Dentine specimens were obtained from sound premolars extracted for orthodontic purpose from the patients of age group 13 to 40 years. All the teeth were stored in 0. 2% thymol at room temperature. In our study, Fluoro calcium phospho silicate (Biomin) showed an average results of 70.37% completely occluded tubules and 23.48% of partially occluded tubules compared to 2.68% and 28.43% in the control group. Conclusion: In our invitro study the treated groups the specimens brushed with combination group (Biomin and Laser) showed the highest percentage of tubule occlusion followed by Biomin alone and then Laser. Hence from the results, it can be stated that combination of Biomin and laser can be considered as the best effective method in office treatment modality for dentinal hypersensitivity because of its ability to occlude more tubules.
