Inflammatory root resorption is a serious complication of dental trauma, which leads to progressive loss of the root structure. This report describes the treatment a previously traumatized young maxillary lateral incisor, severely affected by inflammatory root resorption. An 11-year-old boy presented with pain and mobility in his maxillary incisors which experienced fall trauma 2 years earlier. Radiographic examination revealed incomplete root development of the right central incisor, associated with advanced inflammatory root resorption and a periapical lesion. Following removal of a prior long-term calcium hydroxide dressing, the root canal was submitted to a 2-week irrigation regimen involving 1.25% sodium hypochlorite and 2% chlorhexidine gluconate. Thereafter, the entire root was filled with mineral trioxide aggregate. The radiographic follow up at 6 months showed arrest of root resorption and initiation of periapical healing in the absence of clinical symptoms and mobility. This was followed by advanced osseous regeneration and re-establishment of the periodontal space at 12 and 24 months. From the present case, it can be concluded that mineral trioxide aggregate obturation can be a viable option that can improve the healing outcomes in cases of severe inflammatory root resorption in young permanent teeth.
炎症性根吸收是牙外伤的严重并发症，可导致根结构进行性丧失。本报告描述了一例先前受外伤的年轻上颌侧切牙的治疗情况，该牙严重受炎症性根吸收影响。一名 11 岁男孩因上颌切牙外伤后 2 年出现疼痛和松动就诊，该牙曾受过外伤。影像学检查显示右侧中切牙未完全发育，伴有进行性炎症性根吸收和根尖病变。在去除先前的长期氢氧化钙封药后，对根管进行了为期 2 周的冲洗，包括 1.25%次氯酸钠和 2%葡萄糖酸氯己定。此后，整个牙根均用三氧化矿物聚合体填充。6 个月的放射影像学随访显示，在无临床症状和松动的情况下，根吸收停止，根尖愈合开始。随后在 12 个月和 24 个月时出现了更高级别的骨再生和牙周间隙的重新建立。从本病例可以得出结论，三氧化矿物聚合体填充是一种可行的选择，可以改善年轻恒牙严重炎症性根吸收病例的愈合效果。
