Endodontic management of a perforated and geminated maxillary first premolar with aid of cone beam computed tomography: A case report

Variations in the root canal morphology have been extensively reported in endodontic literature. Gemination is one rare variation frequently seen in anterior teeth which are defined by two clinical crowns joining in one root. This study reports a maxillary first premolar with gemination. Although uncommon, knowing about this anatomical variation can help in successful endodontic treatment.
