Three case reports are presented concerning permanent maxillary molars with fusion of two buccal roots. The morphology is peculiar because it is characterized by the mesiobuccal canal merging into the distobuccal canal in their apical one-third. A thorough review of the literature failed to reveal any previously reported description of permanent maxillary molars with this arrangement of canals, with the exception of a recently reported epidemiological study.
本文报告了3例上颌恒磨牙双颊根融合的病例。其形态独特，特点是近中颊根在根尖三分之一处与远中颊根融合。全面检索文献后发现，除了最近一项流行病学研究外，此前没有关于这种根管形态的上颌恒磨牙的报道。
