It is known that the mandibular first molar can display significant anatomical variations namely the number of root canals, the number of roots and morphology. Mandibular molars may sometimes have an additional root located lingually (the radix entomolaris) or buccally (the radix paramolaris). If encountered, an awareness and understanding of this unusual root and its canal morphology can contribute to the successful outcome of root canal treatment. This case report discusses endodontic treatment of a mandibular first molar with a radix entomolaris, which is a rare entity and poses as an endodontic dilemma for the clinician with respect to diagnosis and subsequent treatment. Clinicians should be aware of these unusual root morphologies in the mandibular first molar which needs strategic treatment as unfilled canals remain a nidus for infection and can compromise treatment outcome.
众所周知，下颌第一磨牙可表现出显著的解剖变异，即根管数量、牙根数量和形态。下颌磨牙有时可能有额外的牙根，位于舌侧（额外根）或颊侧（副磨牙根）。如果遇到这种情况，认识和了解这种不寻常的牙根及其根管形态有助于根管治疗的成功。本病例报告讨论了一例下颌第一磨牙伴额外根的根管治疗，这是一种罕见的情况，对临床医生的诊断和后续治疗构成了根管治疗难题。临床医生应了解下颌第一磨牙这些不寻常的牙根形态，因为未充填的根管仍是感染灶，会影响治疗效果，所以需要进行策略性治疗。
