Histological examination of 18 erupted and eight unerupted teeth with idiopathic external resorption demonstrated that the pulp remained protected by a thin layer of dentine approximately 23--308 micrometers wide. There was no significant difference between erupted and unerupted teeth.
对18颗已萌出和8颗未萌出的患有特发性外部吸收的牙齿进行组织学检查发现，牙髓受到一层约23至308微米宽的薄牙本质保护。已萌出牙齿和未萌出牙齿之间没有显著差异。
