The mesiobuccal root of the maxillary molars is well known to pose a hindrance during endodontic therapy. Presented here is a case of a maxillary left second molar where three canals were located in its mesiobuccal root with the use of visual and diagnostic aids. Difficulties encountered during the process of unveiling the tooth's internal anatomy were discussed. The dilemmas encountered pertained to the root canal configuration, the nomenclature of the extra canals, and the justification for the presence of a third canal. The root canal configuration of 3-2-1 was confirmed for the mesiobuccal root using information gained from clinical, radiographic, and multi-detector computed tomography (MDCT) scan findings. This case demonstrates the need for efforts to locate extra canals in the mesiobuccal root of the maxillary molars as their internal anatomy remains a mystery.
上颌磨牙的近中颊根在根管治疗过程中是众所周知的阻碍因素。本文介绍了一例上颌左侧第二磨牙病例，通过视觉和诊断辅助手段，在其近中颊根发现了三条根管。讨论了在揭示该牙内部解剖结构过程中遇到的困难。遇到的困境涉及根管形态、额外根管的命名以及第三条根管存在的合理性。利用临床、影像学和多排螺旋计算机断层扫描（MDCT）扫描结果所获得的信息，确认了近中颊根的根管形态为3-2-1。该病例表明，由于上颌磨牙近中颊根的内部解剖结构仍然是个谜，因此需要努力寻找其中的额外根管。
