In this article the defense mechanisms of the pulp and pulp reactions to injury were briefly reviewed. Iatrogenic pulp injury was emphasized and guidelines for prevention of such injury were provided. These could be summarized as follows: Never cut dry. Always use a water coolant to prevent heat generation and desiccation of dentin. Use a protective base or liner with materials that are known to be irritating to the pulp (groups II and III) regardless of cavity depth. Use a protective base in all deep cavities where the possibility of a microscopic exposure of the pulp exists, regardless of the nature of the material to be used for restoration.
本文简要回顾了牙髓的防御机制以及牙髓对损伤的反应。强调了医源性牙髓损伤，并提供了预防此类损伤的指导原则。这些原则可总结如下：切勿干切。始终使用水冷却剂以防止牙本质产热和干燥。对于已知会刺激牙髓的材料（II类和III类），无论窝洞深度如何，都应使用保护基底或衬层。在所有存在牙髓微小暴露可能性的深窝洞中，无论修复所用材料的性质如何，都应使用保护基底。
