摘要氢氧化钙在牙髓中的应用是治疗外牙根吸收的常用方法。已经提出了几种作用机制。本研究应用扫描电镜和光镜观察了牙髓氢氧化钙对牙根面和牙周膜细胞的影响。猴子的侧切牙被拔出，在牙根表面做一个凹槽，然后立即再植牙齿。一些牙齿的牙髓被唾液中的细菌感染。氢氧化钙在根管内的应用引起实验沟内吸收牙本质的细胞和形成修复性牙骨质的细胞的有限坏死。在未感染的牙齿，暂时性强直发展。具有杀菌和坏死作用的高pH值似乎足以解释氢氧化钙对牙根吸收的治疗作用。
Abstract Pulpal application of calcium hydroxide is a common treatment for external root resorption. Several mechanisms of action have been suggested. In the present investigation, the effect of pulpal calcium hydroxide on cells at the root surface and in the periodontal ligament was studied by means of scanning-electron microscopy and light microscopy. Lateral incisors in monkeys were extracted, a groove was made- in the root surface and the teeth were then immediately replanted. The pulps of some teeth were infected by bacteria from the saliva. Application of calcium hydroxide in the root canal caused a limited necrosis of the cells resorbing dentin as well as the cells forming reparative cementum in the experimental groove. In the non-infected teeth, a temporary ankylosis developed. The high pH having a bactericidal and necrotizing effect seemed to be sufficient to explain the therapeutic effect of calcium hydroxide on root resorption.
