Atypical odontalgia--a diagnostic dilemma.
Atypical odontalgia (AO) is a chronic orofacial pain condition of unclear pathophysiology, often presenting as toothache or pain at an extraction site. Idiopathic, psychogenic, vascular, and neuropathic causes have been proposed. In view of demonstrable somatosensory changes, and responses to management proposed for other forms of neuropathic pain, the best current evidence supports a neuropathic hypothesis. It is proposed that certain individuals with as-yet-undefined genetic vulnerability can develop AO when exposed to certain risk factors, including invasive dental treatment. The diagnosis and treatment of AO can be challenging, but can be aided by a multidisciplinary approach. Two cases of differing complexity are presented in this paper.
