This report presents a case of endodontic treatment of a mandibular first premolar with 3 root canals and a review of the literature concerning root canal anatomy of lower premolars. It is stressed that, even in teeth with a low frequency of abnormal root canal anatomy, the possibility of additional root canals has to be considered in the clinical and radiographic examination of the patient.
本报告介绍了一例下颌第一前磨牙三根根管的根管治疗病例，并对有关下颌前磨牙根管解剖的文献进行了综述。需要强调的是，即使在根管解剖异常发生率较低的牙齿中，在对患者进行临床和影像学检查时，也必须考虑存在额外根管的可能性。
