The endodontic treatment of mandibular premolars may not be successful because of failure to recognize and/or treat multiple canals when they are present in these teeth. Factors such as an awareness of data pertaining to the number of canals, knowledge of canal morphology, correct radiographic interpretation, and tactile examination of canal walls are important in detecting the presence of multiple canals. These factors, as well as guidelines for subsequent canal preparation and obturation, are provided.
下颌前磨牙的根管治疗可能无法成功，原因是当这些牙齿存在多个根管时未能识别和/或治疗。诸如了解与根管数量相关的数据、根管形态知识、正确的影像学解读以及对根管壁的触觉检查等因素，对于检测多个根管的存在很重要。本文提供了这些因素以及后续根管预备和充填的指导原则。
