Journal of Korean Dental Science, volume 6, issue 1, 2013, Pages 4~12
DOI : 10.5856/JKDS.2013.6.1.4
Purpose: This study sought to verify the usefulness of mini-implant and surgical steel wire in the treatment of mandibular fracture through the objective identifi cation of the change of bone structure and bone density before and after reduction by evaluating radiological change through fractal analysis when mandibular fracture is treated using mini-implant and surgical wire. Materials and Methods: This study looked at 45 patients (males: 38, female: 7) diagnosed with mandibular fracture in the oral and maxillofacial surgery division of Chung-Ang University Dental Hospital and who received open reduction and intra-osseous fi xation. Result: The average fracture dimension values were higher for the group of the patients who had mini-implants and surgical wire treatment. Conclusion: Based on the results of the study on the usefulness of the reduction technique using mini-implant and surgical steel wire in the treatment of mandibular fracture through the fractal analysis method, the reduction technique using mini-implant and surgical steel wire is regarded as an effective method of minimizing the gap between mandibular fracture fragments.

Purpose: To report the successful results of using chin bone graft and autogenous tooth bone graft material (AutoBT) in alveolar cleft patients. Materials and Methods: Five patients with alveolar cleft defects underwent alveolar bone grafting. Three patients were treated using chin bone graft, and the other two patients underwent AutoBT graft. After implant site development using chin bone graft in the fi rst three cases, endosseous implant restorations were placed. In case #4 and 5, AutoBT graft material was placed to guide the normal eruption of partially impacted maxillary right canine and to the upper docking site after distraction osteogenesis. Result: Successful implant restorations with closure of the oronasal fistula were achieved in alveolar cleft defect reconstruction using either chin bone graft (Case #1, 2, 3) or AutoBT graft material (Case #4, 5). Case #4 showed enlarged follicle of the right maxillary canine, indicating a normal eruption guide pattern. Conclusion: Both chin bone graft and AutoBT graft showed favorable outcomes in reconstructing alveolar cleft defects. Autogenous tooth bone graft opens up the possibility of avoiding harvesting autogenous bone graft with complications and morbidities.
Transglutaminase 2 mRNA Expression in Salivary Gland Tumor Cell Line
Chun, Yoon Kwon ; Lee, Chong Heon ;
Journal of Korean Dental Science, volume 6, issue 1, 2013, Pages 22~26
DOI : 10.5856/JKDS.2013.6.1.22
Purpose: Transglutaminase 2 (TGase 2) is expressed by tumor necrosis factor-
in various carcinoma. The role of TGase 2 expression in salivary gland tumors is not clear yet. Established slaivary gland tumor (SGT)cell line has been used to study the pathogenesis of salivary gland adenocarcinoma on a cellular level in vitro. The pupose of this study were to examine mRNA expression of TGase 2 in SGT cell line compared to other tumor cell lines, and to apply these results to the pathogenesis of salivary gland tumor. Materials and Methods: After SGT, SCC-15, HN 4, and HeLa tumor cell lines were cultured under preconfl uency, and 3 days after postconfl uency, the cells were harvested for total RNA extraction and cDNA preparation. Result: Reverse transcription polymerase chain reaction for semiquantitative mRNA analysis was done. TGase 2 mRNA expression was not induced by confl uency in all the cell lines. TGase 2 mRNA expression was variable but markedly enhanced in SGT cell line. Conclusion: mRNA expression of TGase 2 should play an important role in the pathogenesis of SGT cell line originated from ductal cell.

The introduction of osseointegrated dental implants in dentistry brought about a new era in everyday dental practice. For the past 50 years, prosthetic restoration with implant-supported prosthesis has developed into a viable and predictable treatment option. Alongside the increasing use of dental implants is the occurrence of many complications during implant placement (surgery), in the mechanical or prosthetic problem, and in the biological aspect. In particular, abutment or screw fracture as one of the mechanical complications can put the dentist in a tight spot in a clinical situation. It is hard to remove the fractured abutment and screw to restore it properly. Therefore, it is very important that clinicians consider possible complications in advance and make an appropriate treatment plan. We discuss cases of abutment fracture and mechanical/prosthetic complications together with the causes and solutions.

Fibrous dysplasia is a benign fi bro-osseous lesion wherein normal bone is replaced with an excessive proliferation of cellular fibrous connective tissue intermixed with irregular bony trabeculae. Fibro-osseous lesions like fibrous dysplasia are often associated with non-epithelial cysts, such as simple bone cyst. The etiologic and pathogenic relationships between fi brous dysplasia and simple bone cyst have not been conclusively established. Nonetheless, the mechanism of cyst formation in fibro-osseous lesion associated with simple bone cyst can be said to differ from that of the typical simple bone cyst of the jaws. This article reports a case of bilateral lesions including fi brous dysplasia and simple bone cyst on each site and reviews the pathogenesis of cyst formation in the fibro-osseous lesion.
