  1. All results are expressed as mean ± SD.
  2. Non significant: at P >0.05.
  3. Significant: at P < 0.05.
  4. P1 = significance between Well differentiated SCC group and other groups.
  5. P2 = significance between Keratinizing moderately differentiated SCC and other groups.
  6. P3 = significance between Non Keratinizing moderately differentiated SCC and Poorly differentiated SCC.
