Comparative Evaluation of Two Novel Natural Desensitizing Agents on Dentinal Tubule Occlusion: A Scanning Electron Microscopy Study.

Aim: The present in vitro study is aimed to compare the effectiveness of dentinal tubule occlusion of two natural-based desensitizing toothpaste (Bentodent Desensitizer and Fang Farm Mint) and Novamin-based toothpaste (Shy-NM) under scanning electron microscope (SEM).

Materials and methods: A total of 60 root dentin discs (3 mm-thick) were obtained from recently extracted permanent premolar teeth and were randomly divided into four groups based on the desensitizing toothpaste used, each group with 15 samples: Group I: Control, group II: Shy-NM, group III: Bentodent desensitizer, group IV: Fang Farm Mint. Samples were brushed for 2 min twice daily with a soft toothbrush with respective pea size amount of toothpaste for 14 days manually. The samples were evaluated for dentin tubule occlusion under SEM at ×4000 magnification.

Results: Statistical analysis was done using one-way ANOVA and Tukey post hoc multiple procedures. All test groups showed significantly more dentinal tubule occlusion when compared to control group. Shy-NM showed significantly more dentinal tubule occlusion when compared to Bentodent desensitizer and Fang Farm Mint.

Conclusion: All desensitizing toothpastes were effective in dentine tubule occlusion compared to the control group. Shy-NM provides effective dentin tubule occlusion compared to other toothpastes and thereby can be considered a promising option to relieve dentinal hypersensitivity (DH).

Clinical significance: Shy-NM can effectively reduce DH. Bentodent desensitizer and Fang Farm Mint can be a safer alternative to relieve DH.
