Oro-antral Communication is an unnatural communication between the oral cavity and maxillary sinus and when it fails to close spontaneously, it remains patent and is epithelialized so that oro-antral fistula develops. It is a common occurrence following removal of maxillary premolars and molars because of anatomic proximity of root apices of these teeth and maxillary antrum. Signs and symptoms of oro-antral fistula varies from free escape of fluids, pain, pus leakage, voice alteration, to pan-sinusitis. Several surgical options exist for its management, in particular the buccal fat pad technique, which has proved to be an effective and a reliable technique. We report in this article two-succefull cases of oro-antral fistula managed with buccal fat pad.

Introduction Morphea, or localized scleroderma, is an inflammatory disease that leads to sclerosis of the skin and underlying tissues due to excessive collagen deposition. Its etiology remains elusive. Morphea also affects oral and perioral tissues, the most common clinical manifestations being facial skin and tongue rigidity. Below, we present a case of morphea with oral manifestations. Case presentation A 17-year-old patient was referred to our department of oral surgery by her dermatologist for possible oral morphea involvement. She presented pigmented skin lesions involving the right labial-chin region. On palpation, the skin of her perioral was sclerotic. the panoramic radiograph showed a shortening of the roots of the 46/47 with a developmental delay of the 48 compared to the 38. A bone biopsy was performed between 46/47 and distal to 48. histological examination showed bone tissue with fibrous and collagenous reorganization in favor of scleroderma. Conclusion The management of plaque morphea is multidisciplinary. The role of the dentist is very important to avoid any oral complications.
