PURPOSE The purpose of this study was to improve the treatment methods for the mental foramen by comparing the directly measured values with the radiographic measured values. MATERIALS AND METHODS One hundred and twelve mental foramina (72 males, 40 females) that were exposed during the operation were examined. The patients' age ranged from 12 to 69(More)
OBJECTIVES The purpose of this study was to evaluate the responses of peri-implant tissue in the presence of keratinized mucosa. STUDY DESIGN A total of 276 implants were placed in 100 patients. From the time of implant placement, the average follow-up observation period was 13 months. The width of keratinized mucosa was compared and evaluated through the(More)
OBJECTIVES The purpose of this study was to compare the clinical, radiologic, and histopathologic features of 71 intraosseous ameloblastomas. STUDY DESIGN Data with respect to the patients' ages, sex, tumor locations, and surgical treatment history, as well as the radiographic findings and number of recurrences, were analyzed. The histologic types of and(More)
PURPOSE The purpose of this study was to assess the efficacy of demineralized bone powder (DBP) alone or combined in a mixture with platelet-rich plasma (PRP) used to enhance osseointegration of dental implants in a dog model. MATERIALS AND METHODS Tissue integration was assessed using standard histomorphometric methods at 6 and 12 weeks after surgery. A(More)
We developed a novel bone grafting material that incorporates autogenous teeth (AutoBT), and provided the basis for its clinical application. AutoBT contains organic and inorganic mineral components and is prepared from autogenous grafting material, thus eliminating the risk of an immune reaction that may lead to rejection. AutoBT was used at the time of(More)
OBJECTIVES The purpose of this study was to examine the usefulness of Periotest and Osstell Mentor (a resonance frequency analysis) as nondestructive analytical tools for determining implant stability in clinics, to evaluate the precision of both instruments, and to determine the applicability of these measured values as clinically relevant indices.

PURPOSE The purpose of this study was to investigate the nonspecific physical and psychological symptoms in patients who suffered from temporomandibular joint disorder (TMD) using the Research Diagnosis Criteria (Axis II) for TMD diagnosis (RDC/TMD). STUDY DESIGN A total of 317 patients were included (M: 75, F: 242). The signs and symptoms of physical,(More)
MicroRNA (miRNA) is a small noncoding RNA molecule, 19–25 nucleotides in length, which regulates several pathways including cell development, cell proliferation, carcinogenesis, apoptosis, etc. In this study, the over-expression of microRNA-205 (miR-205) increased the number of apoptotic cells by at least 4 times compared to the control. In addition,(More)
PURPOSE To evaluate the effect of particulate dentin-plaster of Paris with and without platelet-rich plasma (PRP) on bone healing and new bone formation around titanium dental implants in a canine model. Histologic sections and histomorphometric analysis of the defects were obtained at 6 and 12 weeks after surgery. MATERIALS AND METHODS Three circular(More)
PURPOSE This retrospective report evaluates the incidence of intra- and postoperative complications of orthognathic surgery and their relevance. PATIENTS AND METHODS The clinical records and radiographs of 301 patients who underwent surgery at Chosun University Dental Hospital, Korea, over an 8-year period between 1998 and 2005 were examined.
