치아가 상실되면 주위 치조골의 개조와 흡수가 일어나면서 위축성 무치악을 초래하게 되고, 치은부착은 점차적으로 감소된다. 이에 따라 총의치의 지지력 감소, 저작 효율의 저하와 통증으로 인해 무치악 환자들은 의치 사용의 어려움을 경험한다. 이를 개선하기 위해 하악에 2개의 임플란트를 식립하고 어태치먼트를 장착하는 피개의치의 형태가 유지력 측면에서 바람직한 치료 방법으로 우선적으로 고려되고 있다. 본 증례는 오래된 상, 하악 무치악을 가진 환자로 하악에 2개의 임플란트를 식립하고, 상악은 총의치, 하악은 Locator$^{(R)}$ attachment를 이용한 임플란트 피개의치로 제작하였다. 본 증례에서 기능적, 심미적으로 만족스러운 결과를 얻었기에 수복 과정과 결과에 대하여 보고하고자 한다. Loss of tooth results in remodeling and resorption of surrounding alveolar bone which causes atrophic edentulous ridge and gradually decreasing gingival attachment. As a result, edentulous patients face difficulty in using dentures due to pain, decrease of support, decline of masticatory efficiency of complete denture. To improve this, overdenture with implant in the mandible and attachment are considered as a treatment of choice as a favorable treatment. In this case, a patient with edentulous ridge for long period is rehabilitated by complete denture in maxilla and implant overdenture using Locator$^{(R)}$ attachment in mandible.

This study the presents survey results of a families living with children with disabilities in northern Seoul (Nowon-gu and Dobong-gu) that provides various educational services. This study investigates the current usage and needs of community resources for children with disabilities by the families in the inclusive and segregated care as well as education centers to provide information for the effective implementation of the current system. A total of 109 surveys were distributed and 62 (57%) were returned. 44 families in the 14 inclusive care and education centers as well as 18 families in the 2 segregated care and education centers participated in this study. They were asked to report on access to community resources that include compulsory education, family support, medical treatment, counseling services, commuting support, ways to gain necessary information, current use, and further needs for community resources for their children. Research results indicated that families in two different types of child care centers needed differentiated community services. Parents who use a segregated child care center demanded physical accessibility and increased numbers of highly qualified teachers; however, parents who use the inclusive child care center require the unified information system for the community resources. Survey findings are discussed related to differences between the two types of child care centers. Implications for sharing comprehensive information through child care teachers and directors of child care centers and future research are also discussed.

김정화,서성용,김나홍,유정현,이동운,Kim, Jung-Hwa,Seo, Seong-Yong,Kim, Na-Hong,Yu, Jung-Hyun,Lee, Dong -Woon 대한심미치과학회 2017 Journal of the Korean Academy of Esthetic Dentistr Vol.26 No.1

임플란트 식립시기가 심미적인 부분에 영향을 미치는 것에 대한 연관성을 평가하기 위해 전치부 영역에 식립된 34개의 임플란트 (27명 환자)를 후향적으로 조사했다. 즉시, 조기 및 지연식립으로 시기별로 그룹을 나누고 모든 환자를 보철완료 1년후에 연조직 평가를 시행했다. 통계적으로 그룹별 유의한 의미는 없었다. 식립 시기에 상관없이 만족할 만한 최종결과를 위해 다양한 골이식술과 연조직 이식술이 이루어졌다. 즉, 식립시기로 그 결과를 결정지을 수 없다는 점은 다각적인 면에서 고려사항이 요구된다는 점을 시사한다. Purpose: This retrospective study is to evaluate whether the timing of implant placement and the result of esthetic outcomes are related. Materials and Methods: Among the patients who had undergone single implant surgery on anterior area from 2010 to 2013 in Veterans Health Service Medical Center, 34 implants in 27 patients (24 male and 3 female) were selected and categorized into 3 groups according to the timing of placement, which are group D (Delay), group E (Early) and group I (Immediate). Aesthetic indices used included the Pink Esthetic Score (PES). It has 7 variables scores, such as mesial papilla, distal papilla, a level of soft-tissue margin, soft-tissue contour, alveolar process, soft-tissue color, and soft-tissue texture. Each variable ranges from 0 to 2, therefore total 14 points are highest. All patients were received by regular follow-up at least 1-year. One examiner measured PES on the intraoral photos. Each patient was considered as a statistical unit for statistical analysis. Statistical analyses were performed using a commercially available statistical software (SPSS Statistics 21.0, IBM Corp., Armonk, NY, USA). Kruskal-Wallis test was used for inter-group comparisons. Statistical significance was set at P<0.05. Result: Mean score in Group D, Group I, and Group E were $11.5{\pm}1.5$, $11.4{\pm}1.8$, and $11.3{\pm}1.8$ respectively. In Kruskal-Wallis test, there are no differences (P=0.989). Conclusion: In this limited study suggests that clinical aesthetic results can be achieved with all treatment protocols. Finally, various factors can be considered to produce the esthetic results.

가와사끼병 환아에서 흉부 X-선 검사의 변화와 혈중 Tumor Necrosis Factor-α에 대한 연구

김지영,권정현,김경효,유정현,홍영미,Kim, Ji Young,Kwon, Jung Hyun,Kim, Kyung Hyo,Yu, Jung Hyun,Hong, Young Mi 대한소아청소년과학회 2005 Clinical and Experimental Pediatrics (CEP) Vol.48 No.5

목 적 : 가와사끼병에서 흉부 X-선 검사에서 변화가 나타나는 빈도, 변화 양상, 염증성 cytokine과의 관계를 알아보고자 하였으며, 가와사끼병 환아에서 흉부 X-선 검사에서 이상 소견이 있을 때 염증 정도를 예측할 수 있는지 알아보기 위하여 본 연구를 시행하였다. 방 법 : 2003년 1월부터 2004년 5월까지 이화의대 동대문병원 소아과에서 가와사끼병으로 진단된 환아 84명을 대상으로 흉부 X-선 검사 결과를 동일 방사선과 전문의가 판독하였다. 흉부 X-선에서 정상 소견을 보이는 군과 비정상 소견을 보이는 두군으로 나누어, 발병 당시 각 군의 관상동맥 확장 정도, 혈청 TNF-${\alpha}$, Mycoplasma 항체, 혈색소, 백혈구, 혈소판, 적혈구 침강속도와 C 반응 단백을 비교 연구하였다. 결 과 : 대상 환아 84명 중에서 흉부 X-선 검사에서 이상 소견을 보인 경우는 43명(51.2%)이었다. 흉부 X-선 검사에서 기관지주위둘러쌈(peribronchial cuffing) 22.4%, 그물결절음영 17.7%, 과도통기(hyperaeration) 8.2%, 폐포경화 3.5%, 흉막삼출 1.2%, 무기폐 1.2%에서 관찰되었다. 흉부 X-선 검사에서 정상 소견을 보인 군과 비정상 소견을 보인 두 군에서 평균 연령, 성별과 발열 기간은 유의한 차이가 없었으며, 혈색소, 백혈구, 혈소판, 적혈구 침강 속도와 C 반응 단백도 두 군에서 유의한 차이가 없었다. 양측 관상동맥 직경은 두 군에서 유의한 차이는 없었고, 혈중 TNF-${\alpha}$ 농도도 두 군간에 유의한 차이가 없었다. 비정상 소견을 보인 군에서 Mycoplasma 항체가를 측정한 결과 12.5%에서 1 : 320 이상의 양성을 보였다. 결 론 : 가와사끼병으로 진단된 환아에서 흉부 X-선 검사의 이상 유무로 염증의 심한 정도를 판단하는 것은 제한점이 있다. 가와사끼병 환아에서 Mycoplasma와의 관련성에 대해서는 향후 더 연구가 필요하리라 생각된다. Purpose : Kawasaki disease(KD) is a multisystemic inflammatory vasculitis of unknown etiology. Many complications other than cardiovascular involvement have been recognized in KD. However, there have been few reports published concerning involvement of the lungs in this disease. The purpose of this study was to examine the relationship between serum TNF-${\alpha}$, the degree of coronary artery dilatation and chest X-ray(CXR) findings. In addition, we have investigated serum anti-Mycoplasma antibody(AMA) titers in patients with KD who have abnormal CXR findings. Methods : Eighty four patients with KD were included in this study(group I; 41 patients with normal CXR fndings, group II; 43 patients with abnormal CXR findings). Serum levels of TNF-${\alpha}$ and AMA titer were measured. Results : We reviewed the CXR findings and clinical courses of 84 patients with Kawasaki disease and found abnormal CXR findings in 43 patients(51.2 percent). Peribronchial cuffing was the most frequent abnormality(22.4 percent). In the group with abnormal CXR findings(group II), a statistical difference was not noted in age, sex, duration of fever, hemoglobin, WBC, platelet, ESR, and CRP levels and incidence of coronary arterial lesions as compared with the group having normal CXR findings(group I). No difference was noted in serum TNF-${\alpha}$ level between group I and group II. 2 patients(12.5 percent) of 16 KD patients with abnormal CXR findings have positive AMA titer(above 1 : 320). Conclusion : Most of the abnormal CXR findings in KD patients were peribronchial cuffing. The abnormal CXR findings in KD patients did not mean severe inflammations. It is difficult to consider that CXR abnormalities are related to coronary arterial lesions. In addition, further study on the relationship between Mycoplasma infection and Kawasaki disease is needed.

N/A Objectives: To evaluate the effects of HRT to mammographic breast density in postmenopausal women and to define the factors affecting mammographic density Material and Methods: 96 postmenopausal women receiving HRT at Ewha Womans University were selected and mammography was done at baseline and at least one more time on follow up. We assessed the effects of HRT to mammographic density using American College of Radiology Breast Imaging Reporting and Data System coding in postmenopausal women and tried to define the factors affecting mammographic density via logistic regression models. Results: Most of women following HRT showed no change and 17.7% of women showed increase in breast density. Increased density was apparent in less than 24 months after start of HRT. There were no statistical differences in distribution of mammographic density in different age group, duration of HRT use and type of HRT regimen groups. Logistic regressioin models were used to examine the effect of duration of menopause and HRT, age at menopause, parity, type of HRT regimen and age on mammographic density and these variables were not statistically significant. Conclusion: Relatively low portion of women following HRT showed increase in breast density and thease increased density occurred in less than 24 months after start of HRT. Increased mammographic density may be a risk factor for breast cancer and it reduces accuracy of mammography. So regular mammography should be followed in women after start of HRT, and information of taking HRT should be given to radiologists.
