Keratocystic odontogenic tumor: case report with CT and ultrasonography findings
Sumer, A. Pinar,Sumer, Mahmut,Celenk, Peruze,Danaci, Murat,Gunhan, Omer Korean Academy of Oral and Maxillofacial Radiology 2012 Imaging Science in Dentistry Vol.42 No.1
Keratocystic odontogenic tumor (KCOT) is a benign odontogenic tumor with a potentially aggressive and infiltrative behavior. KCOT is most commonly occurred in mandible and demonstrate a unilocular, round, oval, scalloped radiolucent area, while large lesions may appear multilocular. An important characteristic of KCOT is its propensity to grow in an antero-posterior direction within medullary cavity of bone causing minimal expansion. Definitive diagnosis relies on histological examination. In this report, a KCOT that had an expansion both buccal and lingual cortical bone is described including its features in computed tomography and ultrasonographic exams. The lesion was removed surgically via an intraoral approach under local anesthesia and histologically reported as a KCOT.

Treatment of unilateral buccal crossbite with mandibular symphyseal distraction osteogenesis
Nurhat Ozkalayci,Mete Ozer,Mahmut Sumer 대한치과교정학회 2011 대한치과교정학회지 Vol.41 No.1
The aim of this report is to present the treatment of a 14-year-old boy with scissors-bite. Mandibular symphyseal distraction osteogenesis (MSDO) with tooth-supported distractor was performed to expand the mandible, and intermaxillary cross elastics were used. The mandible was expanded approximately 9 mm. Asymmetric widening was done by using cross elastics and MSDO simultaneously. The buccal crossbite was corrected successfully. After a 2-year observation period, widening of the mandible using this procedure was judged to be stable. (Korean J Orthod 2011;41(1):59-69)

Aspergilloma of the maxillary sinus is considered rare in immunocompetent patients, but a considerable increase has recently been seen in the incidence of reported cases. Dental procedures involving the antral region are thought to predispose individuals to this form of aspergillosis. Because aspergilloma shares similar clinical features with other sinus pathologies, its diagnosis may be delayed. Thus, an early diagnosis confirmed by a histopathological examination plays a crucial role in the adequate management of aspergilloma. This article provides a concise review of the reported cases of aspergilloma associated with dental procedures and reports 2 new cases of aspergilloma in middle-aged female patients, with a presentation of their cone-beam computed tomographic findings.

Alveolar ridge expansion-assisted orthodontic space closure in the mandibular posterior region
Mete Ozer,Berat Serdar Akdeniz,Mahmut Sumer 대한치과교정학회 2013 대한치과교정학회지 Vol.43 No.6
Orthodontic closure of old, edentulous spaces in the mandibular posterior region is a major challenge. In this report, we describe a method of orthodontic closure of edentulous spaces in the mandibular posterior region accelerated by piezoelectric decortication and alveolar ridge expansion. Combined piezosurgical and orthodontic treatments were used to close 14- and 15-mm-wide spaces in the mandibular left and right posterior areas, respectively, of a female patient, aged 18 years and 9 months, diagnosed with skeletal Class III malocclusion, hypodontia, and polydiastemas. After the piezoelectric decortication, segmental and full-arch mechanics were applied in the orthodontic phase. Despite some extent of root resorption and anchorage loss, the edentulous spaces were closed, and adequate function and esthetics were regained without further restorative treatment. Alveolar ridge expansion-assisted orthodontic space closure seems to be an effective and relatively less-invasive treatment alternative for edentulous spaces in the mandibular posterior region.
Benign cementoblastoma of the anterior mandible: an unusual case report

A benign cementoblastoma, which is another name for a true cementoma, is a rare neoplasm that develops from odontogenic ectomesenchyme. It is characterized by a mineralized mass attached to the apex of the root produced by neoplastic cementoblasts. More than 75% of cases arise in the mandible, with 90% of them manifesting in the molar and premolar regions. This neoplasm occurs most commonly in children and young adults, with males being affected slightly more than females. Radiographically, the tumor is observed as a well-defined radiopaque mass that is fused to a tooth root and is surrounded by a radiolucent rim. The treatment of benign cementoblastoma consists of removal of the lesion and extraction of the affected tooth. This report presents an unusual case of benign cementoblastoma in a 31-year-old female, presenting as a densely mineralized mass seen at the apex of the impacted right mandibular canine tooth on radiographs.
