  • Title: Atypical odontalgia: a review.
    Author: Koratkar H, Pedersen J.
    Journal: Northwest Dent; 2008; 87(1):37-8, 62. PubMed ID: 18363287.
    Abstract:
    Since persistent and chronic pain is more common in the head and neck region than in any other part of the body, dentists are more likely to encounter these rather complex cases in their practices. This article is a review and update on atypical odontalgia (AO). AO is a persistent neuropathic pain which may be initiated after deafferentiation of trigeminal nerve fibers following root canal treatment, apicectomy, or tooth extraction, or it may be of idiopathic origin. Details concerning its characteristics, pathophysiology, diagnostic criteria, differential diagnosis, and treatment are made. The aim of this article is to help the clinician with the diagnosis and management of AO. The prognosis for AO is most often only fair, and the administration of tricyclic antidepressants often resolves symptoms. Invasive and irreversible treatment attempts are not recommended.
