Background:
Oral lesions of tuberculosis (TB) are rare and usually associated with the secondary form of the disease.
Aim:
The aim of the present study was to determine the prevalence of oral lesions in a cohort of TB-infected individuals.
Materials And Methods:
The study was carried out in two reference centers for the treatment of TB in Recife, Brazil. All patients treated for TB in the period from July 2008 to March 2009 were included in the study. The data was subjected to descriptive statistical analysis.
Results:
One hundred and twenty-one patients were included in the study. A marked male prevalence was observed, with a male:female ratio of 6.12:1. HIV coinfection was a common event (33%). Head and neck lesions of TB were rare. Cervical node enlargement was observed in seven individuals (5.8%) and oral ulceration in one patient (0.8%).
Discussion:
The low prevalence of oral lesions of TB is in accordance with other studies. Nodal involvement is the most common form of head and neck disease.
Conclusion:
While TB may be a common accompanying feature of HIV disease, orofacial complications of TB are rare in individuals resident in northern Brazil.

Assessment of the Mouth
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
