Abstract: Dentinal hypersensitivity (DH) is defined as short, sharp pain arising from exposed dentine typically in response to chemical, thermal or osmotic stimuli. The present study compares and evaluates the dentin tubule occlusion achieved with 980-nm Diode laser and Gluma desensitizer by means of SEM. Materials and Methods: Thirty dentin disc of extracted sound maxillary and mandibular single rooted teeth were taken. These disc immersed in artificial saliva. Each specimen was etched with Gluma etch 35 gel for 1 min to expose the dentinal tubules and then the specimens were rinsed with distilled water. Specimens were allotted to the three groups of ten each: Group A- Control group, Group B- Diode laser group, Group C- Gluma group. The disc were later analyzed under SEM. The proportions of completely occluded, partially occluded, and open tubules within each group were calculated. The ratios of completely and partially occluded tubules to the total tubules for all the groups was determined, and the data was statistically analyzed. Results: All the two desensitizing agents were effective in the closure of dentinal tubules despite their different chemical compositions and application procedures. On inter-group comparison between Diode laser and Gluma, it was found that Diode laser desensitizer had shown better results in the closure of the dentinal tubules followed by Gluma desensitizer. Conclusion: Although dentinal tubules occlusion was effective by both diode laser (980 nm) and Gluma, Diode laser produced a more complete occlusion of dentinal tubules.
