Multidisciplinary management of a type III palatoradicular groove: an atypical presentation.

The palatoradicular groove is an endodontic anomaly that complicates diagnosis, treatment planning, and prognosis. The extent of this developmental defect dictates the treatment plan. Treatment approaches may vary from simple restoration of the groove to surgical exploration. A palatoradicular groove may lead to pulpoperiodontal complications if not treated precisely. This case report describes a rare presentation of a type III palatoradicular groove in a maxillary lateral incisor that also had an accessory root and periodontal complications.
