Numerous cases of aberrant root and root canal morphology have been described, still diversion occurs more frequently in premolars and molars. To the dental researcher, the aberrations in the mandibular second premolars afford a vast field of interest. The current report presents a clinical case which demonstrates a simplified therapeutic protocol for re-treatment of Vertucci type V root canals. Endodontic access is gained by expanding the endodontic cavity. The instrumentation (preflaring and final preparation) of the root canal system is performed using predominantly hand files in order to preserve to the maximum the tactile feedback in the apical part of the ramification. Obturation is performed through hydraulic condensation. Postoperative radiographs show sufficient three-dimensional sealing of all portals of exit with excellent healing result.
已经描述了许多异常的牙根和根管形态的病例，但牙内偏离仍然更常发生在双尖牙和磨牙中。对于牙科研究人员来说，下颌第二前磨牙的异常情况提供了一个广泛的研究领域。本报告介绍了一个临床病例，该病例展示了一种简化的治疗方案，用于重新治疗 Vertucci 类型 V 根管。通过扩大牙髓腔获得牙髓入口。根管系统的预备（预扩孔和最终预备）主要使用手用器械进行，以最大程度地保留根尖分叉部分的触觉反馈。通过水力压缩进行填充。术后射线照片显示所有出口端口都有足够的三维密封，愈合效果良好。
