Dentin hypersensitivity (DH) is a common condition caused by exposed dentinal tubules, often requiring treatment with desensitizing agents. This in vitro study conducted at Narayana Dental College and Hospital (Nellore, AP, IND) between January 2022 and March 2022, aimed to evaluate the effectiveness of two desensitizing agents, SDI Riva Star (SDI Ltd., Bayswater, VIC, AUS) and Gluma Desensitizer (Kulzer, Hanau, DEU) in occluding dentinal tubules and their long-term durability following simulated brushing.
Fifty maxillary premolar specimens were sectioned and treated with 17% ethylenediamine tetraacetic acid (EDTA) to expose dentinal tubules. They were divided into three groups: (I) a control group, (II) SDI Riva Star, and (III) Gluma Desensitizer. Tubule occlusion was assessed using scanning electron microscopy (SEM) immediately after application and after one month of brushing.
Both test agents occluded the dentinal tubules effectively (SEM score 1), with no significant difference between SDI Riva Star and Gluma Desensitizer immediately post-application. However, after 30 days of brushing, SDI Riva Star demonstrated superior durability, with significantly better occlusion scores than Gluma Desensitizer (p<0.01).
Both SDI Riva Star and Gluma Desensitizer were effective in occluding dentinal tubules, but SDI Riva Star showed greater durability over time, making it a more effective option for long-term desensitization.
牙本质过敏症（DH）是一种由牙本质小管暴露引起的常见病症，通常需要使用脱敏剂进行治疗。这项于2022年1月至2022年3月在纳拉亚纳牙科学院和医院（印度安得拉邦内洛尔）进行的体外研究，旨在评估两种脱敏剂，即SDI Riva Star（SDI有限公司，澳大利亚维多利亚州贝斯沃特）和Gluma脱敏剂（德国库尔泽公司，哈瑙）在封闭牙本质小管方面的有效性及其在模拟刷牙后的长期耐久性。
将50个上颌前磨牙标本进行切片，并用17%的乙二胺四乙酸（EDTA）处理以暴露牙本质小管。它们被分为三组：（I）对照组，（II）SDI Riva Star组，以及（III）Gluma脱敏剂组。在应用后立即以及刷牙一个月后，使用扫描电子显微镜（SEM）评估小管封闭情况。
两种测试剂均能有效封闭牙本质小管（SEM评分为1），在应用后立即，SDI Riva Star和Gluma脱敏剂之间无显著差异。然而，在刷牙30天后，SDI Riva Star表现出更好的耐久性，其封闭评分显著优于Gluma脱敏剂（p<0.01）。
SDI Riva Star和Gluma脱敏剂在封闭牙本质小管方面均有效，但随着时间推移，SDI Riva Star显示出更大的耐久性，使其成为长期脱敏更有效的选择。
