Oral Squamous Cell Carcinoma (OSCC) is the most common oral malignancy worldwide. The prognosis of the OSCC patient is not significant despite the modern treatment facilities. Late presentation is one of the most crucial cause of this and for that reason, the importance of early diagnosis of OSCC should be the main concern. Till now, incisional biopsy followed by histopathological examination is the gold standard for diagnosis of oral cancer. The aim of the present study is to find out the association of salivary amino acid levels with oral squamous cell carcinoma, whether the levels are increased or decreased in the patient suffering from OSCC. This might be helpful for early diagnosis of oral cancer and better prognosis.
