title: Chronic facial pain associated with endodontic therapy.
abstract: Retrospective study was done on 118 patients who underwent nonsurgical endodontics and then surgical endodontics. Seventy-nine patients had pain before nonsurgical endodontics, and an additional 39 were pain free. After the open surgical procedure, six patients (5%) had continual pain and were considered failures. Three patients (2.5%) were thought to have had posttraumatic dysesthesia, and the other three (2.5%) were considered to have phantom tooth pain. Possible mechanisms for each chronic pain type are discussed.
