牙本质过敏症的共同病理基础是牙本质暴露。尽管对牙本质的疼痛感觉机制目前有几种不同的学说和认识,但作者认为牙本质细胞胞突和牙本质小管是牙本质过敏症病理变化的核心。 为研究牙本质过敏症的自然病理变化过程,作者对不同期的牙本质过敏面做了扫描镜(SEM)观察。 The common pathological basis of dentin hypersensitivity is dentin exposure. Although there are several different doctrines and understandings of dentin pain-sensing mechanisms, the authors suggest that dentin cell tubules and dentinal tubules are central to the pathological changes in dentine hypersensitivity. In order to study the natural pathological changes of dentin hypersensitivity, the authors performed scanning electron microscopy (SEM) on different phases of dentine hypersensitivity.
