A comprehensive knowledge of the anatomy of the root canal is a basic prerequisite for the success of endodontic treatment. Mandibular molars may have an additional root located lingually (radix entomolaris) or buccally (radix paramolaris). An awareness of the potential for and understanding of unusual external and internal root canal mor-phology contributes to the successful outcome of root canal treatment. Here, we report two cases of radix entomolaris to increase awareness and understanding of this unusual morphology so that procedural errors during endodontic therapy might better be avoided.
全面了解根管解剖结构是牙髓治疗成功的基本前提。下颌磨牙可能有一个额外的根，位于舌侧（远中根）或颊侧（副根管）。了解这种不寻常的外部和内部根管形态的可能性并加以认识，有助于根管治疗取得成功。在此，我们报告两例远中根病例，以提高对这种不寻常形态的认识和理解，从而更好地避免牙髓治疗过程中的操作失误。
