Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment protocol. Maxillary second molars are recognized as usually having a single palatal root with a single palatal canal. The incidence of second palatal root in the maxillary second molar is very rare. Two cases are presented in this paper describing the endodontic management of a four-rooted maxillary second molar with two distinct palatal roots and canals and two distinct buccal roots and canals. Clinical examination and radiographs showed the presence of two palatal roots during the root canal procedure. The canals were biomechanically prepared with crown-down technique and obturated using lateral condensation technique with AH-Plus sealer.
根管治疗有时可能会失败，因为牙齿的形态特征会对治疗方案产生不利影响。上颌第二磨牙通常被认为有一个单一的腭根和一个单一的腭根管。上颌第二磨牙出现第二腭根的情况非常罕见。本文介绍了两例上颌第二磨牙四根管的病例，该牙有两个明显的腭根和腭根管以及两个明显的颊根和颊根管。在根管治疗过程中，临床检查和X光片显示存在两个腭根。采用冠向下技术对根管进行生物力学预备，并使用AH-Plus封闭剂通过侧向加压技术进行充填。
