Background: The diagnosis of oral malignancy and epithelial dysplasia has traditionally been based upon histopathological evaluation of full thickness biopsy from lesional tissue. As many studies had shown that incisional biopsy could cause progression of the tumors, many alternative methods of collection of samples had been tested. Oral brush biopsy is a transepithelial biopsy where it collects cells from basal cell layer noninvasively. Aim: To assess the diagnostic accuracy of brush biopsy when compared to histopathology in a group of patients with features of potentially malignancy. Materials and Methods : In the present study, 60 cases of clinically diagnosed leukoplakia are selected and subjected to histopathology and brush biopsy. Results and Conclusion: Results showed that of 16 dysplasia cases confirmed by histopathology, only 12 were positively reported in oral brush biopsy. In 44 cases, the reports are same for histopathology and brush biopsy. The sensitivity of oral brush biopsy is 43.5% and specificity is 81.25% with a positive predictive value of 58.3%. Oral brush biopsy with molecular markers like tenascin and keratins can be an accurate diagnostic test.
