Abstract

Successful endodontic treatment requires thorough knowledge regarding each root canal system of any tooth and probability of extra canals should be considered. Second maxillary molar with two palatal root canals is not frequent and its incidence reported in literatures is about 0.4-2%. The present case report describes non-surgical retreatment of maxillary second mo-lar with two palatal root canals. Radiographic interpretation is difficult in this region; so, very careful examination of pulpal space and using supportive devices such as loupe and operating microscope is recommended to discover any unusual anat-omic features like extra canals.

摘要

成功的牙髓治疗需要对任何牙齿的每个根管系统有全面的了解，并且应考虑存在额外根管的可能性。上颌第二磨牙有两个腭侧根管的情况并不常见，文献报道的发生率约为0.4%-2%。本病例报告描述了对上颌第二磨牙两个腭侧根管进行的非手术再治疗。该区域的影像学解读较为困难；因此，建议非常仔细地检查牙髓腔，并使用放大镜和手术显微镜等辅助设备，以发现任何异常的解剖特征，如额外的根管。
