This is the first case report which documents the successful treatment by apexification of an immature permanent tooth with dens in dente. The patient, an 11-year-old boy in good health, presented with unilateral facial swelling and a "sore tooth." Clinical and radiographic examination revealed a partially erupted anomalous permanent canine with a radiolucent periapical area. After initial management with antibiotics, the anomalous structure within the canine was removed. Calcium hydroxide dressings were placed to facilitate apical closure. After 1 year the canal was filled with gutta-percha using a lateral condensation technique.
这是首例记录通过根尖诱导成形术成功治疗恒牙胚发育不全并伴有牙中牙的病例报告。患者为一名11岁健康男孩，表现为单侧面部肿胀和“牙痛”。临床和影像学检查发现一颗部分萌出的异常恒尖牙，根尖区有透射影。在使用抗生素进行初步处理后，去除了尖牙内的异常结构。放置氢氧化钙敷料以促进根尖闭合。1年后，采用侧向加压技术用牙胶充填根管。
