The ability to recognize the anatomical variations of the root canal system is crucial before starting endodontic treatment, no less important is being able to carry out these treatments based on current scientific evidence. The premolars are the dental pieces with the greatest complexity in their internal anatomy and the ones that appear in the highest percentage compared to other teeth, if a piece presents accessory anatomy, it is highly probable that the contralateral piece presents the same internal anatomy, to this it is known as symmetrical bilaterality, therefore the radiographic images must be executed with proximal and orthoradial projections in order to approximate the 3D shape that these anatomies present and minimize procedural errors. The use of magnification is essential to be able to address the entire root canal system and perform an adequate endodontic treatment. This case report presents the approach to 2 maxillary first premolars from the same patient with 3-canal anatomy, presenting bilateral symmetry.
在开始牙髓治疗之前，识别根管系统的解剖变异的能力至关重要，同样重要的是能够基于当前的科学证据进行这些治疗。前磨牙是其内部解剖结构最复杂的牙齿，与其他牙齿相比出现的比例最高，如果一颗牙齿呈现附属解剖结构，对侧牙齿很可能呈现相同的内部解剖结构，这被称为对称双侧性，因此必须通过近中投影和正位投影来拍摄X光片，以近似这些解剖结构呈现的三维形状并尽量减少操作失误。使用放大设备对于能够处理整个根管系统并进行充分的牙髓治疗至关重要。本病例报告介绍了对同一患者的两颗上颌第一前磨牙进行的治疗方法，这两颗牙齿具有三根管解剖结构且呈现双侧对称性。
