Abstract
Mandibular molars demonstrate considerable variations with respect to number of roots and root canals. The possibility of additional root canals should be considered even in teeth with a low frequency of abnormal root canal anatomy. This paper discusses the endodontic management of the rare anatomical complexity middle mesial canals in mandibular first molar and also serves to remind the clinicians that such anatomical variations should be taken into account during the endodontic treatment of the mandibular molars.
摘要
下颌磨牙在牙根和根管数量方面表现出相当大的变异。即使在根管解剖结构异常发生率较低的牙齿中，也应考虑存在额外根管的可能性。本文讨论了下颌第一磨牙中罕见的解剖学复杂结构——近中中根管的根管治疗，并提醒临床医生在进行下颌磨牙根管治疗时应考虑到这种解剖变异。
