This is a case report on the management of a vital lateral incisor with a radiolucent cervical area associated with the presence of necrotic pulp due to a dens invaginatus (DI) type III. A nine-year-old boy presented to a university pediatric dental clinic with dental trauma. The examination showed poor oral hygiene, an uncomplicated fracture in the permanent maxillary left central incisor, and a fistula near the permanent maxillary right lateral incisor. A radiograph showed that the right lateral incisor had incomplete root development and a type III DI. Although sensitive to thermal pulp testing, tracing of the fistula indicated that the radiolucent area was associated with the DI, extending laterally to the periodontal ligament. Endodontic treatment was performed only in the invagination, keeping the root canal of the lateral incisor vital. After two years of follow-up, complete root formation and injury repair associated with invagination were observed.
这是一篇关于一例重要侧切牙的病例报告，该侧切牙存在与III型牙内陷（DI）导致的牙髓坏死相关的透射性颈部区域。一名9岁男孩因牙齿外伤就诊于大学儿科牙科诊所。检查发现口腔卫生差，上颌左侧恒中切牙有简单骨折，上颌右侧恒侧切牙附近有瘘管。X线片显示右侧侧切牙牙根发育不全且为III型DI。尽管牙髓温度测试敏感，但瘘管追踪表明透射性区域与DI相关，向外侧延伸至牙周膜。仅对内陷处进行了根管治疗，保留侧切牙的根管活力。经过两年的随访，观察到与内陷相关的牙根完全形成和损伤修复。
