摘要/Abstract

摘要：

本文报告1例上颌第一前磨牙三根四根管的发现与诊断过程。通过临床诊断和操作过程中的细致观察和多角度的常规X线牙片,发现并定位了额外根管的存在,并借助锥形束CT和根管显微镜证实三根四根管的存在,最终在手术显微镜下完成了高质量的根管治疗。

关键词: 上颌第一前磨牙, 根管解剖, 根管治疗

Abstract:

This article presented a case of discovering and diagnosing three roots with four canals of the maxillary first premolar. We found and located the extra root canal by clinical diagnosis, careful observation during the operation, and mul-tiangle X-ray. We further confirmed the existence of the three roots with four canals with the help of cone-beam computed tomography. Finally, we verified the success of the high-quality root-canal therapy through root optical microscopy.

Key words: maxillary first premolar, root canal anatomy, root canal treatment
