Management of anatomical root structure in lower premolars with Vertucci type V morphology

Mandibular premolars with complex anatomic aberrations have been reported, making endodontic
treatment of these teeth extremely difficult. A case of endodontic treatment of a mandibular first
premolar presenting bifurcation of the root canal with two independent canals (Vertucci type V
root canal configuration) was described. A 58-year-old woman with no significant medical history
presented with a primary complaint of pain in a previously endodontically treated tooth. Clinical
examination revealed pain on thermal tests. Intraoral periapical radiographs taken at different
angulations revealed a root with a bifurcation at the apical third. The canals were prepared and
individually filled using the vertical continuous wave obturation technique

关于具有复杂解剖畸变的下颌前磨牙，已有相关报道指出，此类牙齿的根管治疗极为困难。本文描述了一例下颌第一前磨牙的根管治疗案例，该病例表现为根管分叉，存在两个独立的根管（即Vertucci类型V根管配置）。一位58岁的女性患者，既往无显著病史，主诉为先前已进行根管治疗的牙齿疼痛。临床检查发现患者在热测试中存在疼痛。不同角度的口腔根尖X线片显示，根管在根尖三分之一处发生分叉。采用垂直连续波充填技术对根管进行预备和个别填充。
