Ectopic sulcular pain: detection and treatment.

Abstract

Patients who present with acute or chronic posterior dental pain but cannot identify the tooth from which the pain originates may suffer from a common but often unrecognized condition. The present article introduces a new term for this disorder, ectopic sulcular pain (ESP), derived from its unusual presentation, location, and defining symptom. It is tempting to call ESP an infection, but this has not been confirmed. In ESP, oral examination reveals no visual abnormalities, and there are no evident fractures, caries, periodontitis, attachment loss, traumatic occlusion, or periapical abscesses. This confusing symptomatology often leads to incorrect diagnosis and, consequently, treatment that fails to relieve the patient's pain. This article discusses ESP and reports 13 cases in which the condition was identified via intraligamental or topical application of an anesthetic agent to numb the gingiva. In 12 patients, ESP was successfully treated with meticulous oral hygiene, chlorhexidine rinses, and, in some cases, oral antibiotics.
