title: Protracted gingival pain associated with free nerve endings-report of a case.
abstract: This report describes a localized painful gingiva in the region of the incisive papilla of 5 years duration in a 68-year-old Caucasian woman. Clinical examination revealed no recognizable lesion. The histological observations showed a relatively large number of free nerve endings within the epithelium and the lamina propria. Excision of the painful area relieved the symptoms.
