Endodontic treatment of mandibular premolars can be difficult due to their aberrant root canal anatomy. Successful nonsurgical root canal treatment requires knowledge of basic root and root canal morphology, and possible anatomical variations of the root canal system. Mandibular second premolars usually have a single root and a single canal, and the presence of 3 canals in separate roots is very rare. Nonsurgical endodontic treatment of such teeth is a challenge. This article presents a rare case of a mandibular second premolar with 3 root canals in separate roots and its endodontic management, with a special emphasis on radiographic interpretation and access refinement during treatment.
由于下颌前磨牙根管解剖结构异常,其根管治疗可能会很困难。成功的非手术根管治疗需要了解基本的牙根和根管形态,以及根管系统可能存在的解剖变异。下颌第二前磨牙通常有一个牙根和一个根管,在分开的牙根中出现3个根管的情况非常罕见。对这类牙齿进行非手术根管治疗是一项挑战。本文介绍了一例罕见的下颌第二前磨牙,其分开的牙根中有3个根管及其根管治疗管理,特别强调了治疗期间的影像学解读和开髓优化。
