Abstract

Mandibular premolars usually have a single root and canal; however, during clinical and radiographic evaluation as part of endodontic treatment it must be noted that variations in anatomical configuration are not uncommon. These teeth may require special canal preparation and filling techniques. This article discusses the treatment recommendations for unusual anatomical configurations in two different mandibular premolars and reports the treatment carried out on these teeth.

摘要

下颌前磨牙通常有一个牙根和根管；然而，在作为牙髓治疗一部分的临床和影像学评估过程中，必须注意到解剖结构的变异并不罕见。这些牙齿可能需要特殊的根管预备和充填技术。本文讨论了两种不同下颌前磨牙异常解剖结构的治疗建议，并报告了对这些牙齿所进行的治疗。
