The purpose of this study was to evaluate the clinical validity of multi-rooted teeth subjected to root-resection treatment. Over a period of 1-7 years, 60 root-resected molars in 59 patients were examined clinically and radiographically. All patients were p0eriodically recalled once or twice a year. Root-resections were due to periodontal, more specifically furcal bone loss or marginal bone loss,in 34 cases and extensive dental carious destruction in 10 cases. In other cases,root-resections resulted from 6 cases of root fracture, 6 cases of periodontal-endodontic combined lesion, and 1 case of endodontic problem. Root-resection was carried out on 26 maxillary molars and 34 mandibular molars. The results are as follows; 1. 14 cases(23.3%) were considered failures. 8 cases(13.3%) of them occurred within the first year(8 cases, 13.3%), 4 cases(6.7%)between 1-3 years, and 2 cases(3.3%) between 4-7 years. 2. 8 cases(13.3%) were considered failures due to periodontal reasons, 3 cases(5%) due to root fracture, 2 cases(3.3%) due to endodontic problem, and 1 case(1.7%) due to prosthetic problem. 3. 37 cases(61.7%) showed up for the recall appointments, and the percentage of failures(13.5%) was lower compared with that of all patients(23.3%). The results of the present study indicate that the prognosis of root-resected teeth is favourable if attention is paid to the selection of proper case and to achieving optimal oral hygiene and periodic check up.

Aplastic anemia (AA) is a serious hematologic disease characterized by hypocellular bone marrow and deficient production of erythrocytes, granulocytes and platelets. Serious complications such as uncontrolled bleeding and bacteremia can occur. A case of severe AA are presented with dental considerations. A 4-year-old boy had been referred from Seoul National University Hospital for dental examination before the hematopoietic stem cell transplantation (HSCT). Treatments were planned under general anesthesia, due to the poor compliance. Following medical consult, dental treatments were performed after platelet transfusion and antibiotic prophylaxis. Postoperatively, neither significant bleeding nor complictation was observed. On the time of the treatment planning. the anesthesiologist and dentist should perform a complete hematological assessment. It is imperative not only platelet counts but also other leukocyte counts are under safe boundaries. It is mandatory to follow strict aseptic precautios for all anesthetic and surgical maneuvers. In severe thrombocytopenic patients, platelet transfusion should be considered. Also, it is recommended to establish a good oral hygiene.

Purpose: This study aimed to analyze the health education conducted for adolescents in the past 10 years by 5-year cycles. Methods: This study was conducted, targeting 200,008 students attending junior high school and high school, using the data of the Korea Youth Risk Behavior Web-based Survey in 2005, 2010 and 2015. The collected data was analyzed by Rao-Scott $x^2$ test, using SPSS program. Results: The overall implementation of health education has increased over the past decade, showing statistically significant differences between 2005, 2010 and 2015 (p<.05). The type of health education given the most was sex education (68.9~74.5%) in 2005 and 2010 and safety education (83.8%) in 2015, whereas the least given health education was personal hygiene education (18.2%) in 2005 and oral health education (22.0~24.0%) in 2010 and 2015. In addition, the implementation rate of health education was statistically significantly lower in high school than in middle school in all three years, 2005, 2010 and 2015. As the grades got higher, the implementation rate of health education showed a statistically significant decrease (p<.05). Conclusion: Health education for adolescents needs to be provided equally. Therefore, it is necessary to prepare an education policy for students to benefit from adequate health.

Purpose : This study aimed to analyze the relationship between local residents' experience of public health education on smoking, drinking, and nutrition and their perceptions of health and happiness, thereby providing data for improving the levels of residents' perceptions of health and happiness through the expansion of public health education. Methods : This study used 2017 data on the health of local communities in Gyeongsangnam-do. SPSS (version 25.0) was employed for the statistical analysis. A t-test and an analysis of variance were conducted in order to examine the levels of local residents' perceptions of health and happiness according to their general characteristics and whether or not they had received public health education on smoking, drinking, and nutrition. Results : Those who resided in a city, were younger, earned money, had high educational background, and had high income level had much experience on smoking, drinking, and nutrition education. Those who lived in a county, were males, were younger, had a high level of education, earned money, and had high income level felt a high level of subjective happiness. Residents who had experienced smoking, drinking, and nutrition education had a high level of subjective perception of general health and oral health. The subjects' experience of public health education was positively correlated with their levels of perception of their health and happiness. Conclusion : Education on smoking, drinking, and nutrition for local residents does not merely provide them with knowledge but also it is conductive to improving their quality of life. Therefore, more opportunities for a larger number of people to receive public health education on diverse topics should be given to increase their levels of happiness.

Wounds that heal with excessive scar formation result in poor functional and aesthetic outcomes. To address this, in our study, visible light cured glycol chitosan (GCH) hydrogels containing endothelial growth factor (EGF) and basic fibroblast growth factor (bFGF) were prepared (GCH-EGF, GCH-FGF and GCH-EGF/FGF) and evaluated their efficacies on the improvement of wound healing in vivo. In vitro release test showed that the growth factors were released in a sustained manner along with initial burst for 24 h. In vitro cell proliferation assay of L-929 mouse fibroblast cell line resulted in the superior ability of GCH-EGF/FGF on the rate. In vivo results demonstrated that the growth factor loaded GCHs further enhanced wound healing compared with GCH. In particular, GCH-EGF/EFG showed the most remarkable wound healing effect among the samples.

완전 무치악 환자의 가철성 보철 수복 치료에서 잔존 치조제의 흡수가 심한 경우 임플란트를 이용하면 부가적인 지지, 유지 및 안정을 제공할 수 있다. 환자의 상태에 대한 정확한 진단 및 평가 없이 보철물을 제작하게 되면 생역학적, 기능적, 심미적으로 불리한 치료 결과를 야기하게 된다. 본 증례의 환자는 개인치과의원에서 상·하악 임플란트 피개의치를 제작하였으나 연조직 통증 및 기존 의치 유지력 저하로 재치료를 위해 내원하였다. 진단 결과 기존 의치의 수직고경이 다소 낮게 설정되어 있어 이를 거상하고, milled bar와 부가적인 attachment를 이용한 임플란트 피개의치를 제작하였다. 이를 통해 증진된 구강위생과 기능적, 심미적인 면에서 만족할 만한 결과를 얻었기에 보고하는 바이다.

Based on data from the Korean Academy for Dental Administration, which has been conducting the Dental Quality Improvement (QI) Contest since 2010, we aimed to provide basic data for the development of dental quality improvement indicators by analyzing the trends of dental quality improvement activities. A total of 54 articles in the dental QI contest from 2015 to 2021 were used to search for frequently used words and to classify the quality of dental care. The criteria for the quality dimension of dental care were first classified into structure, process, and outcome, and secondary classification was performed into patient safety, timeliness, patient-centeredness, equity, efficiency, effectiveness, and accessibility. The frequently used key terms were satisfaction (five times), efficiency (four times), system (three times), and implant (three times). The activities for process evaluation were high at 62.26%, structural evaluation activities at 35.85%, and outcome evaluation activities at 1.89%. According to the components of dental care quality improvement, the activity performed under efficiency was the highest (33.96%), followed by patient-centeredness (18.87%), effectiveness (16.98%), patient safety (15.09%), accessibility (5.66%), timeliness (1.89%), and the equity (1.89%). QI activities in dental hospitals were mainly activities on improvement in structure and process, as well as activities on efficiency, patient-centeredness, effectiveness, and patient safety.
