Proper knowledge of the anatomic structure of the root canal system is a vital prerequisite for successful root canal therapy. This report presents the endodontic management a two-rooted lower first premolar with five root canals. A similar case has not been reported to date. The use of cone beam computed tomography (CBCT) in rare and doubtful cases helps establish an accurate diagnosis and render successful endodontic treatment thereafter. This article helps broaden our knowledge about the possible anatomic diversities as to teeth with more roots and root canals than expected normally.
正确了解根管系统的解剖结构是根管治疗成功的重要前提。本报告介绍了一例有五条根管的下颌第一前磨牙的牙髓治疗情况。迄今为止尚未有类似病例的报道。在罕见和疑难病例中使用锥形束计算机断层扫描（CBCT）有助于准确诊断，并在此后进行成功的牙髓治疗。本文有助于拓宽我们对于牙根和根管数量比正常预期更多的牙齿可能存在的解剖学差异的认识。
