上颌第一磨牙远颊双根管1例

Abstract

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
