Endodontic perforations are common accidents that occasionally happen as a result of misuse or difficult anatomy of some teeth; it may lead to teeth loss unless a good management is provided. Bioceramic (silicate-based) cements like mineral trioxide aggregate have a big role in management of such accidents. This case report aimed to evaluate the ability of five mineral oxides cement "5MO" in sealing two root canal perforations (furcation and postdrill perforations) and inducing clinical and radiographic healing in the periodontal tissues with/without the use of collagen sponge matrix. A 58-year-old healthy female was referred to our dental office complaining of severe pain in the upper left premolars' region. Periapical radiographic examination revealed unsatisfactory root canal treatment of the teeth #24 and #25 with a furcation perforation and a postdrill perforation, respectively. Cone-beam computed tomography "CBCT" scans confirmed the findings of the periapical radiography and revealed the presence of radiolucent lesions surrounding the apex of both teeth #24 and #25. The treatment plan was a nonsurgical root canal retreatment by endodontic access through the full-ceramic crowns. After three years of follow-up, CBCT scans revealed a complete healing and bone formation on both premolars. This case report indicates the use of 5MO cement for endodontic perforations management.
根管穿孔是常见的意外情况，有时是由于某些牙齿使用不当或解剖结构复杂所致；若不进行妥善处理，可能导致牙齿脱落。生物陶瓷（硅酸盐基）水门汀如三氧化矿物凝聚体在处理此类意外情况中发挥着重要作用。本病例报告旨在评估五种矿物氧化物水门汀“5MO”封闭两个根管穿孔（根分叉穿孔和桩道穿孔）以及在使用/不使用胶原海绵基质的情况下诱导牙周组织临床和影像学愈合的能力。一名58岁健康女性因左上前磨牙区剧痛前来我院牙科就诊。根尖片检查显示24号和25号牙根管治疗效果不佳，分别存在根分叉穿孔和桩道穿孔。锥形束计算机断层扫描（CBCT）证实了根尖片的检查结果，并显示24号和25号牙根尖周围存在透射性病变。治疗方案是通过全瓷冠进行非手术根管再治疗。经过三年随访，CBCT扫描显示两颗前磨牙均完全愈合且有骨形成。本病例报告表明5MO水门汀可用于根管穿孔的处理。
