Root canal configuration is an important subject in endodontic practice and dentists should be familiar with all possible types of root canal configuration. A forty-three year old male was referred for root canal treatment of his maxillary left second molar tooth with symptomatic irreversible pulpitis. Pre-operative radiographs showed a three rooted molar. However, after access cavity preparation two palatal and one buccal orifices were detected. The patient was informed of the unusual root canal anatomy and cone-beam computed tomography (CBCT) was ordered for precise evaluation of the anatomy. CBCT image confirmed the presence of one buccal and two palatal root canals; an exceptionally rare condition.
根管形态是牙髓病治疗中的一个重要课题，牙医应熟悉所有可能的根管形态类型。一名43岁男性因上颌左第二磨牙出现症状性不可逆性牙髓炎而前来接受根管治疗。术前X线片显示该磨牙有三个牙根。然而，在开髓后发现了两个腭侧根管口和一个颊侧根管口。告知患者其根管解剖结构异常，并安排了锥形束计算机断层扫描（CBCT）以精确评估其解剖结构。CBCT图像证实存在一个颊侧根管和两个腭侧根管；这是一种极其罕见的情况。
