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. The objectives of the study were -to evaluate effectiveness of Fluoro calcium phospho silicate on dentinal tubules occlusion, to evaluate effectiveness of Fluoro calcium phospho silicate and laser and to compare its effect with Fluoro calcium phosphosilicate alone and laser on dentinal tubule occlusion, and to evaluate the effectiveness of laser on dentinal tubule occlusion. In study setting, SEM analysis was done at Sophisticated test and instrumentation centre, Cochin University of Science and Technology (CUSAT), Kerala. 120 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..

Dentinal hypersensitivity (DH) is characterized by a short, sharp, pain of rapid onset arising from exposed dentin in response to thermal, osmotic, mechanical or chemical stimuli that cannot be attributed to any other form of dental disease or defect

Summary
Dentinal hypersensitivity (DH) is characterized by a short, sharp, pain of rapid onset arising from exposed dentin in response to thermal, osmotic, mechanical or chemical stimuli that cannot be attributed to any other form of dental disease or defect. The prevalence of Dentinal hypersensitivity range from 4 to 73 percentages with highest occurrence in 20yr to 40 yr age group and with incisors, canine and premolars being the most commonly affected teeth.[1] Its occurrence seems to be the consequence of the presence of open dentinal tubules on exposed dentinal surfaces. It is a common problem associated with gingival recession, incorrect tooth brushing habits, parafunctional habits, abrasion due to brushing, dietary erosion, abnormally positioned tooth in the arch, periodontal disease, periodontal surgery, crown preparation, wasting diseases, occlusal wear and aging.[2] Following periodontal therapy, increased root sensitivity is encountered due to the removal of 20-50 μm of cementum during scaling and root planing exposing the dentinal tubules. Patency and permeability of dentin tubule in hyper sensitive dentin was confirmed by several studies and explains why patients with exposed cervical dentine exhibits dentine hypersensitivity.[4,5,6] The hydrodynamic theory states that movement of fluid in the dentinal tubules stimulates the mechano receptors in or near the pulp, which is the reason that the tubule occlusion reduces dentin permeability and proportionality decreases, the degree of dentin hypersensitivity.[7]
