The main goal of endodontic treatment is healing of the periapical tissues which are gained by elimination of bacteria and their byproducts from the canal and prevention from reinfection. Understanding of root canal anatomy is an essential part in endodontic treatment. Anatomic forms and variations in special teeth should be well known, one of them is extra roots/ canals. Although possible aberrations of canal anatomy should be considered for all teeth, some teeth should be highlighted. This review addresses the prevalence, diagnosis (clinical and radiographic), and endodontic management of teeth with extra roots/canals.
牙髓治疗的主要目标是实现根尖周组织的愈合，这通过清除根管内的细菌及其副产物并防止再次感染来达成。了解根管解剖结构是牙髓治疗的重要组成部分。特殊牙齿的解剖形态和变异情况应熟知，额外牙根/根管便是其中之一。尽管所有牙齿都应考虑根管解剖可能存在的异常，但有些牙齿更应予以关注。本文综述了具有额外牙根/根管的牙齿的发生率、诊断（临床和影像学）以及牙髓治疗管理。
