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 molar
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 anatomic
features like extra canals.
