Maxillary first and second molars having unusual palatal root canal morphology with spiral computed tomography findings: Two case reports

A thorough knowledge of the basic root canal anatomy and its variations is necessary for the successful completion of the endodontic treatment. Maxillary first and second molars usually have three roots and three or four canals (two mesiobuccal canals, one distobuccal, and one palatal canal). The incidence of two palatal roots in maxillary molars is quite a rare dental anatomy. The article reports two palatal roots each in maxillary first and second molars found incidentally in two different cases. These cases provide an evidence of variations in the root canals in the palatal root of maxillary first and second molars. Clinicians should thoroughly examine the pulpal floor and radiographs for the possibility of additional canals.
