Knowledge about internal anatomy plays a crucial role in the success of the root canal treatment. Many studies on internal anatomy have repeatedly reported that maxillary lateral incisors have only one canal. The primary aim of this article was to describe successful non-surgical retreatment of a permanent maxillary lateral incisor with two root canals and open apices. The treatment was carried out using dental operating microscope and the canals were obturated with mineral trioxide aggregate (MTA) as an apical plug. A review of literature was also conducted to evaluate the anatomical variations of maxillary lateral incisors.
了解内部解剖结构对根管治疗的成功起着至关重要的作用。许多关于内部解剖结构的研究反复报道上颌侧切牙只有一个根管。本文的主要目的是描述一例具有两个根管且根尖孔开放的恒上颌侧切牙的成功非手术再治疗。治疗过程使用牙科手术显微镜，根管使用三氧化矿物凝聚体（MTA）作为根尖充填物进行充填。还进行了文献综述以评估上颌侧切牙的解剖变异情况。
