Context And Aim: In today's world of advanced dentistry, there are various aspects of restorative, esthetic, and surgical processes. Healing of an extraction socket comprises of bone as well as soft-tissue remodeling with maximum dimensional changes occurring during the first 3 months.

Malignant conversion of oral submucous fibrosis in surgically treated case.

Oral submucous fibrosis (OSMF) is an insidious chronic disease affecting any part of the oral cavity and sometimes the pharynx with epithelial atrophy leading to stiffness of the oral mucosa, causing trismus and inability to eat. However a more serious complication of this disease is the risk of the development of oral carcinoma. We reported the histopathologically proven case of OSMF with initial interincisal mouth opening 2mm which was treated surgically with nasolabial flap technique but failed to follow up and could not do active mouth opening exercises.
