Unusual root canal anatomy in maxillary second molars: two case reports

The aim of this clinical report is to describe the unusual root canal anatomy of 2 maxillary second molars with 2 separated palatal roots and the endodontic treatment procedures for those teeth. In these presented cases, microscopy was useful to identify distopalatal orifice. Radiographic interpretation was difficult owing to the overlap of the buccal and secondary palatal roots.
