摘要/Abstract

摘要： 上颌第一磨牙根管系统复杂多变，远颊双根管发生率十分低。本文报道了一例上颌第一磨牙远颊双根管行根管治疗病例，并针对上颌第一磨牙根管系统特征、遗漏根管发生特点以及如何提高根管查全率作出总结。

关键词: 上颌第一磨牙, 远颊双根管, 显微镜, CBCT

Abstract: The root canal system of the maxillary first molar is complicated. The incidence of second distobuccal canal（DB2）in the maxillary first molar is low. This article reported a clinical case of maxillary first molar with a DB2 canal which acquired successful root canal treatment. Additionally, the paper discussed the root canal anatomy of the maxillary first molar, the characteristics of the missing canal and how to improve the ability of locating additional root canals.

Key words: maxillary first molar, second distobuccal canal, operating microscope, CBCT
