摘要/Abstract

摘要：

融合牙通常由两个正常牙胚在发育过程中部分或完全融合所形成，属于牙发育异常。融合牙临床上较为少见，发生于后牙区的融合牙更为罕见。本文报道1例右下颌第一恒磨牙与第二恒磨牙融合，该融合牙具有复杂的根管解剖结构（7个根管），通过锥形束CT对根管数量及位置进行分析，在显微镜的辅助下成功完成了根管治疗。

关键词: 融合牙, 根管解剖, 锥形束CT, 显微根管治疗

Abstract:

Fused teeth are usually formed by the partial or complete fusion of two normal tooth germs during the development process and belong to dental developmental abnormalities. Fused teeth are relatively rare clinically, and those occurring in the posterior tooth area are even rarer. This article reports a case of fused teeth between the first permanent molar and the second permanent molar in the right mandible. This fused tooth had a complex root canal anatomical structure (seven root canals). The number and location of the root canals were analyzed by cone beam computed tomography, and root canal treatment was successfully completed with the assistance of microscope.

Key words: fused teeth, canal anatomy, cone beam computed tomography, microscopic root canal treatment
