Introduction: Dentinal Hypersensitivity (DH) is a painful sensation felt in the affected teeth and is a common dental problem. Complete elimination of dentinal hypersensitivity still remains a myth but occlusion of dentinal tubules, has shown promising results. Aim and objective: To compare dentinal tubule occlusion using Novamin or Biomin containing desensitizing toothpastes. Methodology: Twenty extracted teeth, unaltered during extraction procedure were included for this in vitro study. The teeth were cut in to three transverse sections (60 specimens) after cleaning and drying. All the specimens were acid etched by applying 6% citric acid solution and equally distributed into three groups (20 specimens). The specimens from Group 1 were brushed with distilled water, Group 2 with Novamin and group 3 with Biomin containing toothpaste, two minutes per session. The specimens were kept in artificial saliva and the procedure was repeated for seven consecutive days and subjected to SEM analysis. The two-dimensional photomicrographs of the surface from the centre of each dentinal block were procured at x500 and x1000 magnification. Results: Both the desensitizing dentifrices containing Novamin and Biomin demonstrated varying degrees of tubular occlusion. Biomin-containing toothpaste (Elsenz) demonstrated 98.81% and Novamin containing toothpaste (SHY-NM) showed 89.84% tubular occlusion. Conclusion: Better Tubular Occlusion was Observed with Biomin containing Elsenz Toothpaste and it can be Advocated for the Treatment of Dentinal Hypersensitivity.
