PURPOSE This study was performed to investigate the incidence and configuration of the bifid mandibular canal in a Korean population by using cone-beam computed tomography (CBCT) imaging. MATERIALS AND METHODS CBCT images of 1933 patients (884 male and 1049 female) were evaluated using PSR-9000N and Alphard-Vega 3030 Dental CT units (Asahi Roentgen Ind.(More)
INTRODUCTION This article represents a new design of expander-spike expander-to correct transverse maxillary deficiency. This new type appliance is easy to fabricate, more hygienic, and less soft-tissue irritation because of elimination of acrylic plate. In addition, because of the position of mini-implant, it can provide a relatively parallel alveolar(More)
PURPOSE This study was performed to evaluate the feasibility of visualizing soft tissue lesions and vascular structures using contrast-enhanced cone-beam computed tomography (CE-CBCT) after the intravenous administration of a contrast medium in an animal model. MATERIALS AND METHODS CBCT was performed on six rabbits after a contrast medium was(More)
PURPOSE This study was performed to investigate the influence of object shape and distance from the center of the image on the volumetric accuracy of cone-beam computed tomography (CBCT) scans, according to different parameters of tube voltage and current. MATERIALS AND METHODS Four geometric objects (cylinder, cube, pyramid, and hexagon) with predefined(More)
Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare carcinoma, which arises within the jaws without connection to the oral mucosa and presumably develops from a remnant of odontogenic epithelium. We present a case of solid type PIOSCC in a 52-year-old male patient complaining of dull pain on his left lower molar. In this case, early stage PIOSCC(More)
