The success of nonsurgical endodontic management depends on the complete elimination of infection that compromises the tooth function. Thorough knowledge about the root canal anatomy is one of the principal factors in achieving a successful outcome. The morphology of root canals is not always typical. Maxillary molars, known for varied morphology, require advanced imaging modalities such as cone-beam computed tomography. This case report describes a series of four maxillary molars with different forms, numbers, and configurations of root canals and with unusual morphology, including a case of a third mesiobuccal canal, a case of a second mesiobuccal canal with two palatal canals (mesiopalatal and distopalatal), a case of three mesiobuccal canals, three distobuccal canals, and two palatal canals (mesiopalatal and distopalatal), and a case of taurodontism, where different access cavity modifications, diagnostic methods, and magnifications were considered.
非手术牙髓治疗的成功取决于彻底消除损害牙齿功能的感染。全面了解根管解剖结构是取得成功治疗结果的主要因素之一。根管形态并不总是典型的。以上颌磨牙根管形态多样而闻名，需要采用诸如锥形束计算机断层扫描等先进的成像方式。本病例报告描述了四颗上颌磨牙，其根管形态、数量和结构各异，且形态异常，包括一例有第三近中颊根管的病例、一例有两个腭根管（近中腭根管和远中腭根管）的第二近中颊根管的病例、一例有三个近中颊根管、三个远中颊根管和两个腭根管（近中腭根管和远中腭根管）的病例，以及一例牛牙症的病例，针对这些病例考虑了不同的开髓腔改良方法、诊断方法和放大倍数。
