PURPOSE The aim of this study was to evaluate the effectiveness of coronectomy for teeth whose root apices are very close to the inferior alveolar canal. PATIENTS AND METHODS The 43 patients of this study needed removal of their lower third molar, whose root apices were very close to the inferior alveolar canal. These patients underwent 47 coronectomies.(More)
Phototherapy (PT) is the most widely used form of treatment for unconjugated hyperbilirubinemia. One possible harmful consequence of PT is of a genetic nature. High levels of bilirubin may lead to oxidative damage in newborns: photochemical reactions may produce toxic photoproducts, probably peroxides. In order to investigate this hypothesis further under(More)
BACKGROUND The most severe complication after the removal of mandibular third molars is injury to the inferior alveolar nerve or the lingual nerve. These complications are rather uncommon (0.4% to 8.4%) and most of them are transient. However, some of them persist for longer than 6 months, which can leave various degrees of long-term permanent disability.(More)
The desmoplastic variant of ameloblastoma (DA) is characterized by unique histological and radiographic features. It is histologically characterized by an abundance of densely collagenous stroma with small nests and strands of likely compressed odontogenic epithelium. Although radiographic examination of ameloblastomas usually reveals unilocular or(More)
OBJECTIVE To investigate the frequency of unilateral or bilateral foramen of Vesalius (FV), number of FV present on one side, and presence of a septum on FV. METHODS We bilaterally examined, 347 sphenoid bones of collections of the Department of Anatomy, Istanbul Faculty of Medicine, Istanbul University, Istanbul and Dokuz Eylul Faculty of Medicine,(More)
De Quervain disease is the stenosing tenosynovitis of the first extensor compartment of the wrist. It is diagnosed with a history of pain at the radial aspect of the wrist and a positive Finkelstein test. Although anatomic variations, such as a septum within the compartment, are considered as risk factors, bony anatomy of distal radius and its correlation(More)
STUDY DESIGN A morphometric evaluation of pedicle projections in 29 cervical spinal columns (C3-C7) for three-dimensional surgical anatomy for safe surgery was proposed. OBJECTIVE In this study, pedicles and intimate structures of the subaxial vertebrae from C3 to C7 were evaluated to provide some morphometric data for cervical transpedicular screw(More)
The most superior part of the superficial layer of the supinator muscle is named as the arcade of Frohse (AF). The deep branch of the radial nerve runs under this arch. The AF is reported to be the most common structure causing entrapment neuropathy of the deep branch of the radial nerve. The aim of our study was to reveal the anatomical properties and(More)
Teratomas originating from the oral cavity are named as epignathus. It is a rare type of teratoma. An 11-day old male newborn was diagnosed with cleft palate and intraoral masses. The mass on the right side was protruding from the mouth. Another one on the left side was extending from the nasopharynx to the oropharynx. The diagnosis of mature teratoma was(More)
