Background: The pathogenesis of oral submucous fibrosis (OSF) still remains conflicting and has been linked to alterations in epithelial thickness, fibrosis, and vascularity. Although changes in these individual parameters have been extensively studied in relation to epithelial dysplasia their combined relation with dysplasia has not been studied much. Any such relation, if present, may further help in understanding this disease process. Therefore, the aim of this study was to assess the relationship between epithelial thickness, fibrosis, and vascularity with dysplasia in OSF. Materials and Methods: The study consisted of 30 OSF patients. Incisional biopsy was taken from the most fibrosed area of the buccal mucosa. Hematoxylin–Eosin-stained slides were assessed for epithelial thickness, fibrosis, and vascularity using image analysis software. The slides were also assessed for epithelial dysplasia. Relationship of epithelial atrophy, fibrosis, and vascularity with dysplasia was assessed using one-way ANOVA. Pearson's correlation coefficient was used for evaluating the relationship between epithelial thickness, fibrosis, and vascularity. Results: Epithelial dysplasia was found in all patients. Eleven patients had mild (36. 67%), thirteen had moderate (43.33%), and six had severe (20%) dysplasia. None of the parameters were found to have a significant relationship with dysplasia. However, moderate and positive correlation was found between epithelial thickness and fibrosis. This relation was statistically significant. Conclusion: Positive correlation between epithelial thickness and fibrosis in present study therefore contradicts the hypothesis of fibrosis induced epithelial atrophy. As dysplasia is influenced by multiple factors therefore habits and burning sensation needs to be incorporated in future studies assessing dysplasia in OSF.
