Abstract

Oral Submucous Fibrosis (OSMF) is a chronic progressive scarring oral disease predominantly affecting people of South Asian origin. It is characterized by juxtaepithelial inflammatory cell infiltration followed by fibrosis in the lamina propria and submucosa of the oral mucosa. The pathogenesis of the disease is not well established and a number of mechanisms have been proposed regarding the pathogenesis. A renewed interest has been shown in myofibrobasts which have been implicated to play a significant role in the pathogenesis of OSMF. The myofibroblast were initially identified by means of electron microscopy in granulation tissue of healing wounds as a modulated fibroblast exhibiting features of smooth muscle cells, with prominent bundles of microfilaments, dense bodies scattered in between, and gap junctions. The presence of myofibroblasts has successively been described in practically all fibrotic situations characterized by tissue retraction and remodeling. This review paper is an attempt to identify all the studies involving myofibroblasts and explaining the pathogenesis in a simplified manner.
