The purpose of this article is to emphasis the importance of early diagnosis of primary Tuberculosis of the mouth, which may be misdiagnosed when oral lesions are not associated with any apparent systemic infection1. This helps in the understanding of disease processes but also can provide an invaluable aid in clinical diagnosis and patient management. This study should help to form a bridge between oral disease and the pulmonary Tuberculosis. The more number of the cases is an effective academic teaching tool with considerable practical value in daily practice. An appreciation of the significance of the knowledge about pulmonary tuberculosis helps to prevent needless delays in treatment and helps to eliminate the expense of unnecessary laboratory tests and consultations.
