The present 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).
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.
Statistical analysis was done using one-way ANOVA and Tukey 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.
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).
Shy-NM can effectively reduce DH. Bentodent desensitizer and Fang Farm Mint can be a safer alternative to relieve DH.

本研究旨在通过扫描电子显微镜（SEM）比较两种天然脱敏牙膏（Bentodent脱敏剂和方广薄荷牙膏）和诺华敏基牙膏（Shy-NM）对牙本质小管的封闭效果。
从近期拔除的恒牙前磨牙中获取60个根牙本质盘（3毫米厚），根据使用的脱敏牙膏将其随机分为四组，每组15个样本：第一组：对照组，第二组：Shy-NM，第三组：Bentodent脱敏剂，第四组：方广薄荷牙膏。使用软毛牙刷，每天手动刷牙两次，每次2分钟，使用豌豆大小的相应牙膏，持续14天。在SEM下以4000倍放大率评估样本的牙本质小管封闭情况。
采用单因素方差分析和Tukey多重检验进行统计分析。与对照组相比，所有测试组的牙本质小管封闭均显著增加。与Bentodent脱敏剂和方广薄荷牙膏相比，Shy-NM的牙本质小管封闭显著增加。
与对照组相比，所有脱敏牙膏在牙本质小管封闭方面均有效。与其他牙膏相比，Shy-NM能有效封闭牙本质小管，因此可被视为缓解牙本质过敏（DH）的一个有前景的选择。
Shy-NM可有效降低DH。Bentodent脱敏剂和方广薄荷牙膏可作为缓解DH的更安全替代品。如何引用本文：Kar PP, Saraf PA, Kamatgi L, 两种新型天然脱敏剂对牙本质小管封闭的比较评价：一项扫描电子显微镜研究。《当代牙科实践杂志》2024；25（9）：873 - 877。
