Abstract

A case is reported of a 44-year-old male who was referred with persistent pus discharge associated with his UL2 which had been root treated on two occasions. Radiographic examination revealed a radiolucency of approximately 8 mm diameter. An apicectomy was performed and histopathological examination revealed the presence of mature birefringent hair-shaft structures within a chronic periapical periodontitis.

Clinical Relevance: This article presents a rare occurrence, the presence of human hair in the periapical tissues.

Article

Periapical periodontitis refers to inflammation and destruction of periradicular and/or periapical tissues, the most common cause being endodontic infection resulting from pulpal necrosis. Other causes can be trauma or endodontic treatment.1,2 A chronic periapical periodontitis may present as a discharging sinus, a tooth which is tender to percussion, or may be asymptomatic and discovered on routine clinical examination.3 The associated tooth is non-vital.3,4 Periapical radiolucencies are common and 90% are attributed to chronic periapical periodontitis or periapical cysts.4Table 1 gives a differential diagnosis of periapical radiolucencies.

Radiographic appearances of chronic periapical periodontitis vary from slight widening of the periodontal ligament space to a well defined radiolucency. A condensing osteitis is often associated with the lesion owing to the formation of sclerotic bone in reaction to continued inflammation.3,10 Radicular cysts (inflammatory dental cysts) are characterized as radiolucencies measuring greater than 1 cm in diameter and are a direct sequela of chronic periapical periodontitis.3 A radiographic image can only lead to a provisional diagnosis and histological examination should be utilized to establish a definitive diagnosis.11
