The success of endodontic therapy is based on good endodontic access, correct cleaning and shaping, and adequate root canal obturation. However, endodontic treatment is also dependent on a sound knowledge of the internal anatomy of human teeth, especially when anatomical variations are present. Certain anatomical changes may be present to varying degrees, and it is important to report these to improve the understanding and expertise of endodontic specialists. With this aim in mind, this study reports an example of a maxillary first molar showing unusual anatomy (four roots and six root canals) and describes the endodontic treatment that was employed.
牙髓治疗的成功基于良好的牙髓通路、正确的清理和成形以及充分的根管充填。然而，牙髓治疗还依赖于对人类牙齿内部解剖结构的充分了解，尤其是在存在解剖变异的情况下。某些解剖变化可能会不同程度地出现，报告这些变化对于提高牙髓专科医生的理解和专业技能很重要。出于这个目的，本研究报告了一例上颌第一磨牙显示异常解剖结构（四个牙根和六个根管）的病例，并描述了所采用的牙髓治疗方法。
