牙本质过敏症是指牙齿上暴露的牙本质受到机械、化学或温度刺激时,产生的一种特殊的酸、“软”、疼痛的症状。牙本质过敏症不是一种独立的疾病,二十多种牙体疾病的一种症状。目前,牙本质过敏症的发病率逐年上升,正成为口腔科一个日益严重的问题。目前有较多的产品声称可以封闭牙本质小管,减少牙本质过敏症。

本研究采用定性和定量相结合的方法来探讨不同的产品对牙本质小管封闭的有效性。

研究搜集了人前磨牙和磨牙,制备了牙本质磨片。使用6种不同的牙膏处理牙本质磨片,将其中一种牙膏处理牙本质磨片作为阳性对照组,一个阴性对照组(不使用牙膏处理),模拟牙刷刷牙处理牙本质磨片一年。将一半牙膏处理过的牙本质小管放入青檬汁中,酸蚀处理。使用标准化的扫描电子显微镜拍照并转换成二进制的黑白照片。黑色的影像代表的是开放的牙本质小管,计算黑色影像的个数,并做统计学评价。然后,将一半的牙本质小管破坏,使用能量能量色散X射线光谱(EDS)对阻塞牙本质小管进行研究。

结果发现,6种牙膏中的5种牙膏在模拟刷牙后开放的牙本质小管数目明显降低。3种牙膏处理过的牙本质在酸蚀后有明显的变化。EDS显示,3种牙膏处理后,一部分牙本质小管封闭,然而,一部分牙本质小管在酸蚀后发现没有封闭。

因此得出结论,有些牙膏可以封闭一部分牙本质小管,但是这种封闭是不稳定的,经酸酸蚀后,牙本质小管又可以暴露出来。牙本质小管的封闭依赖于活性成分,单纯使用牙膏不足以有效的封闭牙本质小管。
