Internal root resorption (IRR) is characterized by progressive loss of tooth substance initiating at the root canal wall as a result of clastic activity. The use of periodontal surgery and mineral trioxide aggregate is a good approach to repair lesions with periodontal communication (perforating IRR). This case describes the treatment and follow-up of a maxillary central incisor with perforating IRR in a 56-year-old male patient where root canal treatment, periodontal surgery, and white mineral trioxide aggregate were employed to achieve complete repair and to restore function. Clinical findings and periapical radiographs indicated success after a 5-year follow-up.
内吸收（IRR）的特征是由于破骨细胞活动，从根管壁开始出现牙体组织的进行性丧失。使用牙周手术和三氧化矿物凝聚体是修复伴有牙周相通性病变（穿孔性IRR）的良好方法。本病例描述了一名56岁男性患者上颌中切牙穿孔性IRR的治疗和随访情况，采用根管治疗、牙周手术和白色三氧化矿物凝聚体实现了完全修复并恢复了功能。临床检查结果和根尖片显示5年随访后取得了成功。
