A case report involving vertical root fracture in an endodontically treated mandibular left first molar is presented. Pain and extensive tissue damage occurred in the area 2 years after root canal therapy. The periapical radiograph suggested endodontic failure, and re-treatment was initially considered. However, the problem was related to a complete vertical root fracture in the distal root, which was only visible after removal of the gold crown. The tooth was extracted because severe periodontal destruction had been caused by the root fracture.
本文报告一例经根管治疗的下颌左侧第一磨牙发生垂直根折的病例。根管治疗后2年，该区域出现疼痛和广泛的组织损伤。根尖片显示根管治疗失败，最初考虑进行再治疗。然而，问题是远中根发生了完全垂直根折，只有在去除金冠后才能看到。由于根折导致了严重的牙周破坏，该牙被拔除。
