Abstract

Abstract : Oral submucous fibrosis (OSF) is a high risk precancerous condition characterized by changes in the connective tissue fibers of lamina propria and deeper parts of mucosa. Mast cells are local residents of connective tissue and have been identified to participate in fibrotic process. These cells produce pharmacologically active substances necessary for the physiological function of our body in response to various stimuli as and when required and also play a significant role in the pathogenesis of oral diseases. Ten healthy volunteers and 30 clinically diagnosed OSF cases with histopathological confirmation were included in the study. Immunohistochemical (c-kit) as well as acidified toluidine blue staining techniques were used to evaluate density and expression of mast cells. The mast cell density assessed using c-kit and toluidine blue showed significant difference in various stages of OSF. In general the mean number of mast cells obtained using c-kit was found to be more than that obtained using toluidine blue in various stages of OSF. The comparison of mast cell densities using immunohistochemistry (c-kit) and toluidine blue stain confirmed that c-kit is a more reliable technique to assess mast cell density in OSF.
