摘要

牙内陷是指在牙胚发育过程中,牙釉质形成器或上皮根鞘过度增生并折叠成牙乳头,从而诱发牙冠或牙根发育异常。在严重的情况下,内陷的通道与牙髓和牙周组织相连,往往会引起牙髓病和根尖周病。该病解剖形态复杂,给术前诊断和临床治疗增加了难度。本文报告了一例通过锥形束 CT 和显微镜辅助进行非手术治疗的上颌侧切牙双隐窝Ⅲ型(Ⅲa 和Ⅲb)根尖周炎病例。随访一年后,患牙无症状,根尖周病变明显减轻。

Non-surgical treatment of maxillary lateral incisor double dens invaginatus type Ⅲ with apical periodontitis.

Dental invagination is an abnormality of the crown or root development induced during tooth germ development when the enamel-forming apparatus or epithelial root sheath overpopulates and folds into the papilla. In severe cases, the invaginated channels are connected to the pulp and periodontal tissues, often causing endodontic and periapical diseases. The complex anatomical pattern of this disease adds difficulty in its preoperative diagnosis and clinical operation. In this paper, we report a case of non-surgical treatment assisted by cone beam CT and microscopy for maxillary lateral incisor double dens invaginatus type Ⅲ (Ⅲa and Ⅲb) with apical periapical infection. After 1-year follow-up, the affected tooth was asymptomatic and the periapical lesion was significantly reduced.
