Permanent maxillary second molars' root canal treatment due to their root configurations complexity and high root canal systems variations, are one of the most problematic teeth. Accordingly, clinicians should consider unusual canal morphology to reduce the rate of missed canals. A thirty-year-old female was referred for root canal treatment of her maxillary right second molar tooth with obvious recurrent caries under restoration and necrotic pulp. Pre-operative radiographs showed the unusual morphology and cone-beam computed tomography was ordered for precise evaluation of the root canal anatomy. The principal aim of this paper is to report a five-root canals maxillary second molar, with two palatal root canals and a palatal root-like enamel pearl canal.
由于上颌第二恒磨牙根管形态复杂且根管系统变异大，其根管治疗是最具挑战性的牙齿治疗之一。因此，临床医生应考虑到异常的根管形态，以降低根管遗漏率。一名30岁女性因上颌右第二磨牙修复体下明显的复发性龋和牙髓坏死前来接受根管治疗。术前X光片显示其形态异常，遂进行锥形束计算机断层扫描以精确评估根管解剖结构。本文的主要目的是报告一例有五条根管的上颌第二磨牙，其中包括两条腭侧根管和一条类似腭根的釉珠根管。
