Dens invaginatus (DI) is a dental malformation occurring in several morphologic types. Consequently, treatment of teeth affected by DI can get complicated because of the complex root canal anatomy. The aim is to describe how to manage a rare report of a DI with necrotic pulp held within the vital pulp of a maxillary lateral incisor. Oral fistula was found on the buccal mucosa of the apex of the vital maxillary lateral incisor with a DI having necrotic pulp. Endodontic treatment of the maxillary lateral incisor and of the tract canal of DI was realized. Clinical disappearance of oral sinus tract was observed after 10 days. On the contrary, the disappearance of radiolucent area occurred after 6 months. A proper and prompt diagnosis is necessary to carry out effective prevention protocols or prevent consequences generating nonrecoverable endo-perio diseases.
牙内陷（DI）是一种出现多种形态类型的牙齿畸形。因此，由于根管解剖结构复杂，受DI影响的牙齿治疗可能会变得复杂。目的是描述如何处理一例罕见的上颌侧切牙活髓内伴有牙髓坏死的牙内陷病例报告。在上颌侧切牙根尖的颊侧黏膜发现口腔瘘管，该侧切牙为牙内陷且伴有牙髓坏死。对上颌侧切牙及牙内陷的管道进行了根管治疗。10天后观察到口腔窦道临床消失。相反，6个月后透射区消失。进行有效的预防方案或预防产生不可恢复的牙髓-牙周疾病的后果需要正确及时的诊断。
