Root canal system is complex to understand because of its unpredictable nature. It differs for different teeth and for the same teeth in different individuals. Successful endodontic therapy thus depends on the clinician's ability to anticipate and look for these variations. A mandibular first molar with six root canals represents a rare anatomical variant, particularly when four canals are found in distal root. This case report discusses successful nonsurgical endodontic management of two-root mandibular first molar with four distal canals and two mesial canals reported for the first time in Indian population. Cone beam computed tomography was used as a diagnostic method to confirm the position and presence of 4 root canals in the distal root.
根管系统因其不可预测的特性而难以理解。不同牙齿以及同一牙齿在不同个体之间的根管系统都存在差异。因此，成功的牙髓治疗取决于临床医生预测和查找这些变异的能力。具有六个根管的下颌第一磨牙是一种罕见的解剖变异，尤其是当在远中根发现四个根管时。本病例报告讨论了首次在印度人群中报道的具有四个远中根管和两个近中根管的双根下颌第一磨牙的成功非手术牙髓治疗。锥形束计算机断层扫描被用作诊断方法，以确认远中根中四个根管的位置和存在情况。
