Early Stage Oral Submucous Fibrosis is Characterized by Increased Vascularity as Opposed to Advanced Stages

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
