Introduction: The degree of vascularity of the diseased mucosa in Oral Submucous Fibrosis (OSMF) has always been a matter of debate with conflicting results. Knowledge of this aspect is important to understand pathogenesis of OSMF, which in future could be translated into therapeutic strategies.

Aim: In the present study, attempt has been made to investigate parameters like Mean Vascular Density (MVD), Total Vascular Area (TVA) and Mean Vascular Area (MVA) using CD34 antibody.

Materials and Methods: Forty five previously untreated histopathologically diagnosed cases of OSMF were retrieved from archives and fifteen age and sex matched healthy volunteers without habits were included in the control group. Sections were immunohistochemically stained for CD 34 and morphometric analysis was performed. For statistical analysis ANOVA, Kruskal Wallis test and Mann Whitney U tests were used and p-values <0.05 were considered statistically significant.

Results: MVD was more in Stage I OSMF followed by Control, Stage II and Stage III with statistically significant differences (p< 0.001). Statistically significant differences were observed in the MVD between control versus Stage III OSMF. Similarly, TVA was statistically significant when compared between control versus OSMF, control versus Stage II OSMF, control versus Stage III OSMF, Stage I versus Stage II OSMF, Stage I versus Stage III OSMF, and Stage II versus Stage III OSMF. For MVA, significant differences were between control versus OSMF, control versus Stage II OSMF, control versus Stage III OSMF, Stage I versus Stage III OSMF and Stage II versus Stage III OSMF.

Conclusion: Angiogenesis is seen in early stages of OSMF with decreasing trend in advanced stages. Decreased vascular areas seen in advanced stages could be attributed to the increasing fibrosis surrounding the blood vessels.
