Supernumerary teeth that are present in the molar region may be evident based on crowding and impaction, but most cases are asymptomatic and discovered as incidental findings during routine radiological examinations. This article reports the case of a 29-year-old woman who presented with a severe feeling of pressure in the region of the maxillary third molars that had been increasing in intensity for weeks. A clinical examination revealed crowding of the maxillary anterior teeth despite the completion of orthodontic treatment and an erupted third molar with localized gingivitis in the second quadrant. A radiographic examination revealed bilateral supernumerary maxillary fourth and fifth molars, so cone-beam computed tomography was performed to locate the supernumerary teeth precisely for a preoperative diagnosis and comprehensive treatment planning. This report presents the radiological and surgical case management of a rare case of bilateral supernumerary molars and reviews the literature regarding epidemiology and treatment options.

Sinus Schneiderian membrane elevation surgery is widely performed for dental implant placement in the maxillary posterior region. With regard to sinus elevation surgery, various complications can occur and lead to implant failure. For successful implants in the maxillary posterior region, the clinician must be well acquainted with sinus anatomy and pathology, a variety of bone graft materials, the principles of sinus elevation surgery, and prevention and management of complications.

IN 1956, Peer presented a very comprehensive account of free fatty tissue transplantation. The use of buccal fat pad had been usually used to reconstruct the perioral defects. The buccal fat pad is a special fatty tissue which is markedly different from subcutaneous fat. And it is a easily accessible fat tissue in oral and maxillofacial region. The buccal fat pad can be used as a free graft or pedicled flap. Recently, buccal fat pad is interested in cosmetic surgery because its' removal for cosmetic purpose has been favorable result. We used the buccal fat as an unlined, pedicled graft for closure of large oroantral fistula. We present a case of report and review of literature.

Neural crest cells have embriologically important role for the development and growth in oral and maxillofacial region. If the early hereditary defect occurs or environmental factors affect these cells diminutive mesenchymal cells are disabled to make neural plate and decreased proliferation of mesenchymal cells result in hypoplastic development of neural crest. As a result, this brings about severe facial malformations such as various located facial clefts and/or loss or duplication of facial structure. These are two cases of accessory maxilla and zygomatic deformity with and without facial cleft.

Transoral vertical ramus osteotomy (TOVRO) procedure can result in a variety of complications. Complications commonly reported include extensive bleeding due to major blood vessel injury, unpredictable fracture, postoperative infection, neurosensory deficit related Inferior alveolar nerve, insufficient osteosynthesis, and temporomandibular joint problem. The authors describe a case of partial necrosis of the mandibular proximal segment following TOVRO, a rarely reported complication. A 37-year-old otherwise healthy woman underwent Lefort l osteotomy and TOVRO to correct mandibular prognathism. Postoperatively, she developed pain and swelling in the right submandibular region and was found to have a partial necrosis of proximal segment.

Burkitt lymphoma is a highly aggressive type of hematopoietic malignancy that is comparatively common in children and young people. It is important that Burkitt lymphoma be diagnosed as early as possible for prompt intervention due to its rapidly progressive, high-grade malignant nature. Dentists, especially maxillofacial surgeons, can play a life-saving role in patients with such unknown malignancy as the first clinical or radiological manifestation might occur in the oral region.

In 1942, Stafne described 35 "bone cavities" at the angle of the mandible. They appeared as unilocular, well-circumscribed, round or elliptical radiolucencies located below the inferior dental canal and between the angle of the mandible and first molar tooth. Since 1942, these lesions have been frequently described under various terms: aberrant or ectopic salivary gland; static or latent or idiopathic defect, cavity or cyst; mandibular salivary gland inclusion; lingual mandibular cavity; and Stafne's cyst, defect or cavity. Usually they were asymptomatic, with a predilection for men between age 50 and 70 years, and almost unilateral. At surgical exploration, they appeared as concavities on the lingual cortex and contained salivary gland tissue, often in continuity with the submandibular gland. In 1957, Richard and Ziskind were the first to report the appearance of a Stafne's cyst in the premolar region. Contrary to posterior defects, the anterior defects are difficult to diagnose clinically because the mandibular canal is not present, and the unilocular radiolucency can be confused with other cysts (radicular, residual, odontogenic, lateral periodontal,etc). The purpose of the present report is to describe an unusual case of Stafne's cyst in the anterior region of the mandible in 58-years-old woman.

Liposarcoma is one of the most common malignant mesenchymal neoplasm, comprising approximately 15% of all soft tissue sarcoma. This is a tumor with an incidence peak between age 40 and 60 years, and is slightly more common in men than women. Although all body region may be involved, the most frequent sites are lower extremities and retroperitoneum but rare in the head and neck region. Liposarcoma can be classified to four subtypes ; myxoid, well-differentiated, round-cell, pleomorphic. The myxoid type is the most common and accounts for almost one half of all liposarcoma. Wide surgical excision with or without radiation therapy has been used to manage this lesion. We report a case of 50-year old man with soft tissue swelling on the left cheek, previously diagnosed as myxoid liposarcoma in the left lower extremity. After radiologic and ultrasonic study and surgical excision with biopsy, the lesion of cheek was diagnosed as myxoid liposarcoma with round cell differentiation.

There are many vessels in oral and maxillofacial region. Therefore blood oozing is a frequent findings in this area when operation takes place. Beacuse of this, most oral and maxillofacial surgeons as well as operators of this region usually use bosmine soaked gauze for oozing control during operation. Theoretically overdose of systemic epiniephrine(bosmine) may lead to pulmonary edema due to secondary systemic volume overload. For this reason, oral and maxillofacial surgeons should give more attention to the use of bosmine soaked gauze. In spite of this possibility, epinephrine induced pulmonary edema using bosmine soaked gauze has not been reported. We experienced one case of pulmonary edema which was induced by epinephrine overdose by bosmine soaked gauze that has not been diluted by mistake in preparing bosmine soaked gauze. The authuors report a case with review of literature.

Cyst is pathologic disease develops in hard tissue as well as soft tissue, which is lined by epithelium filled with liquid, semi-liquid, or air. Origins and symptoms of the cyst are various according to region, and symptoms are malocclusion, diversion of root, tooth mobility, periapical swelling, discoloration and lesion expansion, because the odontogenic cysts begin in the numerous rests of odontogenic epithelium. But almost cysts produce no symptoms unless secondary infection occurs. Treatment of small cysts may include extraction, endodontic therapy, and apical surgery. Treatment of a large cysts usually involves surgical removal (enucleation), Marsupialization(a method of decompression) or combination of two before mentioned. Bone graft is done for helping of bone defect healing at the same time of enucleation This clinical research from January 2000 to December 2005, analyzed by the age, sex, classification, size, region, treatment method, whether or not of bone graft of cyst in the jaw in Daegu Catholic University Hospital.
