Supernumerary teeth: A review on a critical endodontic challenge

Supernumerary teeth are developmental anomalies that might require endodontic treatment for functional and/or esthetic reasons. A review of literature was conducted using appropriate key words (“Supernumerary” OR “Supplemental” OR “Rudimentary” AND “Tooth,” “Mesiodens” OR “Paramolar” OR “Distomolar”) in major endodontic journals (Australian Endodontic Journal, Dental Traumatology, International Endodontic Journal, Journal of Endodontics, and Oral Surgery, Oral Medicine, Oral Pathology) to identify available reports describing the clinical and radiographic landmarks of different forms of supernumerary teeth and discussing the implications of such anatomical variation on root canal treatment procedures. In addition, this article highlights the potential indications of supernumerary teeth for intentional replantation and autotransplantation treatment procedures.
