Many endodontically treated teeth require a post to improve the retention of the coronal restoration, which necessitates removal of the coronal part of the gutta-percha from the canal by thermal method, among other techniques. However, this technique carries the risk of heat conduction to the attachment unit of the periodontium and infliction of permanent damage especially in cases where the remaining root's dentin walls are thin. The overall objective of this article is to report on the clinical manifestations, histologic description, and periodontal management of three cases of heat-induced damage following thermal removal of gutta-percha.
许多经过根管治疗的牙齿需要桩来改善冠修复体的固位，这就需要通过热方法等技术从根管中去除牙胶的冠部。然而，这种技术存在将热量传导至牙周附着单位并造成永久性损伤的风险，尤其是在剩余牙根的牙本质壁较薄的情况下。本文的总体目的是报告三例热去除牙胶后热损伤的临床表现、组织学描述及牙周治疗情况。
