The study was conducted to investigate the immunohistochemical expression of MMP - 9 in epithelial dysplasia and different grades of oral squamous cell carcinomas and to study the possible correlation between increased MMP - 9 immunoexpression and progression of epithelial dysplasia in the studied dysplastic and OSCC lesions. Materials and methods: thirty paraffin blocks of OSCC (10 well differentiated, 10 moderately differentiated and 10 poorly differentiated) and ten paraffin blocks of epithelial dysplasia were immunohistochemically stained with MMP - 9 antibody UR - http://172.23.153.220/th.pdf ER -
