In this era of microscope-assisted endodontics, finding variations in root canal system anatomy is not uncommon. Operating microscopes combined with careful clinical examination and radiographic interpretation can aid the clinician to successfully treat cases with such internal anatomy. The understanding of this view enables the possible location of additional canals in any tooth requiring endodontic treatment. The present clinical article demonstrates a rare anatomical complexity in the mesial root of a mandibular first molar. Four independent root canal orifices were found in this root by clinical detection with the aid of a dental operating microscope. This case shows that additional canals can be located in any root undergoing endodontic treatment and clinicians should always be aware of aberrant internal anatomy.
在这个显微镜辅助牙髓病学的时代，发现根管系统解剖结构的变异并不罕见。手术显微镜结合仔细的临床检查和影像学解读，有助于临床医生成功治疗具有此类内部解剖结构的病例。对这种观点的理解有助于在任何需要牙髓治疗的牙齿中找到额外根管的可能位置。本文展示了一例下颌第一磨牙近中根罕见的解剖复杂性。借助牙科手术显微镜通过临床检测在该根中发现了四个独立的根管口。该病例表明，在任何接受牙髓治疗的牙根中都可能存在额外的根管，临床医生应始终留意异常的内部解剖结构。
