Primary oral tuberculosis: a report of a case diagnosed by polymerase chain reaction

Abstract

We present a case of primary oral tuberculosis, affecting the maxillary gingiva and causing alveolar bone loss in a 34-year-old Colombian female patient. Definitive diagnosis was facilitated by polymerase chain reaction analysis, a useful modern tool for the diagnosis of infectious diseases. The location and clinical presentation of this lesion is unusual and underlines the importance of considering tuberculosis in the differential diagnosis of oral lesions that affect the gingiva and alveolar bone.
