摘要/Abstract

摘要：

牙内陷是在牙齿早期发育阶段成釉器卷曲或增生深入牙乳头而引起的一种罕见的牙齿发育异常，双牙内陷尤为罕见。本文利用锥形束CT辅助诊断上颌侧切牙双牙内陷伴根尖周炎，通过显微根管治疗，1年复查患牙无症状，根尖区低密度影像缩小。

关键词: 双牙内陷, 显微根管治疗, 锥形束CT

Abstract:

Dens invaginatus is a rare developmental anomaly of the teeth that is caused by the infolding of enamel organs or the penetration of their proliferations into dental papillae before calcification has occurred. The presence of double dens invaginatus is extremely rare. This paper describes the use of cone beam computed tomography in the evaluation of a maxillary lateral incisor with double dens invaginatus and periapical periodontitis. The tooth was treated through microscopic root canal therapy. The tooth was free of clinical symptoms, and the periradicular lesion narrowed during the follow-up period of 1 year.

Key words: double dens invaginatus, microscopic root canal treatment, cone beam computed tomography
