Abstract

Mandibular premolars exhibit intricate and diverse root canal anatomy, presenting substantial challenges in endodontic treatment. Uncommon variations, such as the presence of three canals, demand meticulous diagnostic and therapeutic approaches to mitigate the risk of overlooking canals and subsequent treatment failure. This case report highlights three cases of mandibular premolars exhibiting a rare root canal configuration with one mesial and two distal canals, successfully managed using cone beam computed tomography (CBCT) for accurate diagnosis and ultrasonic activation for disinfection. The findings underscore the significance of utilizing three-dimensional imaging and precise canal identification in addressing anatomical anomalies in mandibular premolars, which have been sparsely documented in the existing literature. This report aims to contribute to understanding and managing the rare and complex root canal configurations in endodontics.

摘要

下颌前磨牙呈现出复杂多样的根管解剖结构，给牙髓治疗带来了巨大挑战。一些罕见的变异情况，如存在三条根管，需要采取细致的诊断和治疗方法，以降低遗漏根管及后续治疗失败的风险。本病例报告重点介绍了三例下颌前磨牙呈现罕见根管形态（一条近中根管和两条远中根管）的病例，通过使用锥形束计算机断层扫描（CBCT）进行准确诊断，并采用超声激活进行消毒，成功完成了治疗。研究结果强调了利用三维成像和精确根管识别来处理下颌前磨牙解剖异常的重要性，而现有文献中对此类情况的记载较少。本报告旨在促进对牙髓病学中罕见且复杂根管形态的理解和处理。
