External root resorption can be divided into 3 categories: 1) progressive inflammatory resorption; 2) cervical resorption; and 3) replacement resorption. Cervical resorption is a not well recognized type of progressive external inflammatory resorption. It occurs after injury to the cervical attachment apparatus, mostly in the area of the cervical root surface (precementum) below the epithelial attachment. The present article describes an abnormal case of cervical resorption in a vital lateral maxillary incisor of a 27-year-old male patient. Endodontic treatment and subsequent periodontal plastic-esthetic surgery were performed. Reconstruction of the defect was achieved using mineral trioxide aggregate cement. After 2 years, the tooth showed no pathologic symptoms. The present case demonstrates a novel combined endodontic and periodontal treatment of an external root resorption.
牙根外吸收可分为3类：1）进行性炎性吸收；2）颈部吸收；3）替代性吸收。颈部吸收是一种尚未得到充分认识的进行性牙根外炎性吸收类型。它发生在颈部附着装置受损后，主要位于上皮附着下方的颈部牙根表面（牙骨质前期）区域。本文描述了一名27岁男性患者上颌侧切牙发生颈部吸收的异常病例。进行了根管治疗及随后的牙周整形美容手术。使用三氧化矿物凝聚体水门汀修复缺损。2年后，该牙未出现病理症状。本病例展示了一种牙根外吸收的新型根管治疗与牙周联合治疗方法。
