Primary Gingival Tuberculosis, Diagnosis and Treatment: Case Report

Tuberculosis is a chronic specific granulomatous disease and a major cause of death in developing countries. The clinical presentation of tuberculosis lesions of oral cavity varies widely, including ulceration, diffuse inflammatory lesions, granulomas and fissures. Oral lesions usually appear as secondary to primary tuberculosis infection elsewhere, although primary infection of the oral mucosa by Mycobacterium tuberculosis has been described. We are reporting a case of tuberculosis of gingiva, manifesting as gingival ulceration in a 18 years old female patient. Diagnosis was based on histopathological examination, complete blood count, X-ray chest and immunological investigations with detection of antibodies against Mycobacterium tuberculosis. Anti-tuberculous therapy was carried out for over six months. This case report emphasizes the need for dentists to include tuberculosis in the differential diagnosis of various types of gingival ulcerations not responding to conventional dental treatment.
