Oral cancer is one of the sixth most frequently occurring cancers. Oral squamous cell carcinoma (OSCC) accounts for 90% of all oral cancers. SCC is a malignant neoplasm of mucosal origin. The most co mmon site is lateral border and ventral surface of tongue. The etiology of OSCC is multifactorial. The use of tobacco and betel quid, heavy alcoholic drinking, diet low in fresh fruits and vegetables, viruses, trauma from dental structures and genetics are considered as possible risk factors. Early diagnosis plays an important role in improving prognosis and reducing morbidity and mortality associated with OSCC. It is managed by surgery, radiotherapy, chemotherapy singularly or in combination, but regardless of treatment modality, the 5-year survival rate is poor at about 50%. This can be attributed to the fact that about two-thirds of OSCC already have a large lesion at the time of diagnosis. This present case high lights a case of OSCC induced by a sharp tooth with no deleterious habits history and confirmed by histopathology.
