Aim: Oral submucous fibrosis (OSF) is a potentially malignant disorder with 7.6% of malignant transformation rate into oral squamous cell carcinoma (OSCC). The aim of the study is to assess the genetic markers p16 and ki-67 in OSF, OSCC, and OSCC with the background of OSF and control group. Materials and Methods: Ten cases of each group were stained with p16 and Ki-67 by immunohistochemistry technique. Results: Statistically significant results were found among the four groups with moderate-to-severe expression (P < 0.05) for Ki-67 and results were negative for p16 in all groups. Conclusion: According to our result, p16 is found not significant marker and Ki-67 can be useful as a proliferative index marker for malignancy development in oral precancerous conditions.
