颌骨放射性骨坏死(ORNJ)是头颈部放疗的常见并发症，严重影响患者的生活质量。不仅牙槽外科手术，而且根管治疗也可能损害牙槽骨。本文报告一例因根尖周炎治疗后发生于上颌骨的牙周炎。采用顺铂、依托泊苷为主的放化疗方案，治疗右上颌骨小细胞癌，总剂量为60Gy30Fr。2015年4月，放射治疗后，因根尖周炎，他在右上颌骨第一前磨牙接受根管治疗。在根管治疗6个月后，他的右上颌骨出现了急性炎症的ORNJ，因此用抗生素治疗。2016年4月，在ORNJ治疗后，T1和T2加权磁共振图像显示右上颌第一前磨牙周围有一个低信号区域。这些发现表明，牙髓坏死的根管治疗可能是导致ORNJ的触发因素。(C)2017年亚洲AOMS、ASOMP、JSOP、JSOMS、JSOM和JAMI。爱思唯尔有限公司出版。保留所有权利。
Osteoradionecrosis of the jaws (ORNJ) is a well-known complication of head and neck radiotherapy that may severely impair patient quality of life. Not only dentoalveolar surgery but also root canal treatment may also damage the alveolar bone. This report describes a case of ORNJ in the maxilla following treatment for periapical periodontitis. The patient was treated with chemotherapy and radiotherapy consisting of the course of cisplatin and etoposide, and a total dose of 60 Gy/30Fr for small cell carcinoma of the right-maxillary gingiva. In April 2015, after irradiation therapy, he received root canal treatment in the right-maxillary first premolar because of periapical periodontitis. Six months after root canal treatment, he had developed ORNJ in the right maxilla with acute inflammation, and was thus treated with antibiotics. In April 2016, after treatment of ORNJ, T1- and T2-weighted magnetic resonance images showed a hypointense area surrounding the right-maxillary first premolar. These findings suggest that root canal treatment for dental pulp necrosis may be triggered to cause the ORNJ. (C) 2017 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI. Published by Elsevier Ltd.
