Maintenance of increased mouth opening in oral submucous fibrosis patient treated with nasolabial flap technique.

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. A case of OSMF reported with initial interincisal mouth opening; 8 mm which was treated surgically with nasolabial flap technique followed by active mouth opening exercises for 6 months with Hister's jaw exerciser. The patient could maintain mouth opening of 32 mm at the end of 18-months followup. The patient was observed closely for any malignant changes in the oral cavity.

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. Malignant conversion of OSMF was seen in this case. This is required to assess the progress and evaluate any malignant transformation at the earliest. So, the importance of active co-operation and frequent follow up cannot be overemphasized. The purpose of this study is to emphasize the importance of regular follow up and frequent biopsies to facilitate oral examination and to check any malignant conversion after the surgery.

An endo-aesthetic management of crown dilaceration in a permanent mandibular central incisor.

Traumatic injuries to primary dentition may result in a wide range of developmental disturbances to succedaneous permanent teeth. The prevalence of morphological disturbances, secondary to dental injuries in the primary dentition, ranges from 12% to 69%. One of the morphological disturbances are crown dilacerations which are defined as the displacement of a portion of the developing crown at an angle to the longitudinal axis of the tooth. The prevalence of crown dilaceration constitutes 3% of the total injuries in developing teeth and is usually because of intrusion or avulsion of their primary predecessors. The present article narrates a case of crown dilaceration of a permanent mandibular right central incisor with open apex and large periradicular pathosis and its endo-aesthetic management with 2 years of follow-up.
