Purpose: This study evaluated the predictive performance of a combination of self-report questionnaires, salivary hemoglobin levels, and age as a non-invasive screening method for periodontitis. Methods: The periodontitis status of 202 adults was examined using salivary hemoglobin levels, responses to 10 questions on a self-report questionnaire, and the Community Periodontal Index (CPI). The ability of those two variables and the combination thereof with age to predict the presence of CPI scores of 3–4 and 4 was assessed using logistic regression and receiver operating characteristic (ROC) curve analysis. Results: CPI scores of 3–4 and 4 were present among 79.7% and 46.5% of the sample, respectively. The area under the ROC curves (AUROCs) of salivary hemoglobin levels for predicting prevalence of CPI scores of 3–4 and 4 were 0.63 and 0.67, respectively (with sensitivity values of 71% and 60% and specificity values of 56% and 72%, respectively). Two distinct sets of five questions were associated with CPI scores of 3–4 and 4, with AUROCs of 0.73 and 0.71, sensitivity values of 76% and 66%, and specificity values of 63% and 69%. The combined model incorporating both variables and age showed the best predictive performance, with AUROCs of 0.78 and 0.76, sensitivity values of 71% and 65%, and specificity values of 68% and 77% for CPI scores of 3–4 and 4, respectively. Conclusions: The combination of salivary hemoglobin levels and self-report questionnaires was shown to be a valuable screening method for detecting periodontitis.

매복 구치부 치아의 교정적 이동 : 증례 보고

맹유진,오소희 大韓小兒齒科學會 2009 大韓小兒齒科學會誌 Vol.36 No.4

구치부 매복은 1% 이내로 드문 편이지만 저위 교합, 반대 악궁 치아의 정출, 인접치 경사로 인한 공간 부족 등의 문제가 발생하게 된다. 구치부 치아는 교합 및 악골 발육에 관여하는 기능적으로 중요한 치아이므로 초기 혼합 치열기부터 지속적인 방사선 사진을 찍어 매복 여부를 관찰해야 한다. 매복의 원인에는 치근 발육의 저하, 과잉치, 낭종, 치아종, 유착 등이 있다. 첫 번째 증례에서는 초진 시 치근 발육이 1/2이하라서 자발적 맹출을 기대하였지만 2/3이상 발육 시에도 맹출 하지 못하여 외과적 노출 및 교정적 견인을 시함하였다. 두 번째 증례는 낭종을 포함하는 매복 구치를 주소로 내원하였고 낭종 크기가 작고 인접 부위에 주요한 해부학적 구조물이 없어 완전한 적출술을 시행 후 교정적 견인을 하였다. 교정적 견인 시 해당 치아에 직접 어태치먼트(attachment)를 붙인 후 악하고 지속적인 힘을 적용하는 것이 유착, 외흡수, 치주 부착 소실 등의 부작용이 나타나지 않는다. 또한 고정식 장치를 사용하면 환자의 협조도가 필요 없고 맹출 공간을 확보하면서 호선상에 매복치를 견인 할 수 있다. 본 증례에서는 매복 구치를 외과적 노출 및 교정적 견인을 통해 교합상으로 배열을 하여 양호한 결과를 얻었기에 보고하는 바이다. Impacted molars are not usual with the prevalence rate of less than 1%, however problems such as infraocclusion, extrusion of the opposite tooth and lack of space are caused. If molars are impacted, radiographic check-up and observations are needed as they play an important role in skeletal development and mastication. Causes of impaction are underdevelopment of roots, supernumerary teeth, cysts, odontomas, ankylosis and etc. In our first case, we present impacted molar which was surgically exposed and orthodontically traded. As the developmental state of the root was less than half at first visit, we observed until the root was 2/3 in its length and traction was carried out. The second case is orthodontic traded molar with compleate enucleation of the existing cysts. When trading impacted molars, direct bonding of attachments to the tooth and light continuous forces are recommended so as to ankylosis, external absorption and periodontal attachment loss avoid. Fixed appliances tract the teeth on arch and obtain eruption spaces without patient's cooperation. We report surgically exposed and orthodontically traded molars which resulted in good occlusion and patients satisfaction.

소아환자에서 치료 전 수면 시간이 chloral hydrate 진정 효과에 미치는 영향

맹유진,오소희 大韓小兒齒科學會 2011 大韓小兒齒科學會誌 Vol.38 No.4

소아치과 분야에서 chloral hydrate와 hydroxyzine를 이용한 진정 요법은 가장 보편화된 방법이지만 진정 효과는 약물의 용량, 연령, 체중, 술 전 환아의 수면 시간, 술 전 공복유지 유무, 환아의 건강 상태에 따라 좌우 될 수 있다. 본 연구는 경험적 으로 chloral hydrate 진정 요법 시행 전날 수면 시간이 짧을수록 진정 효과가 더 크다는 점에 착안하여 협조전 단계 환아에 서 chloral hydrate/hydroxyzine을 이용한 진정 치료 시 치료 전 수면 시간과 진정 효과의 관계에 대해 알아보고자 시행 하 였다. 한림대 소아치과에 내원한 환자 중 사전 조사에서 1일 평균 수면 시간이 비슷한 만 2-5세 아이들 37명을 대상으로 chloral hydrate/hydroxyzine 진정 요법 하 치료를 시행하였다. 치수 치료를 포함하여 수복치료를 요하는 아이들을 대상으로 하였 으며 치수치료를 한 환자는 총 11명이었다. 진정 효과는 동일한 평가자에 의해 Houpt 등의 rating scal에 따라 점수를 산정 하여 단순회귀 분석법으로 평가하였고 치수 치료 유무에 따라 진정 효과가 달라지는지 여부를 t-test로 평가하여 다음과 같은 결과를 얻었다. 1. Houpt 등의 rating scale 중 sleep, crying 항목은 전날 수면 시간에 따라 유의하지는 않지만 반비례 상관관계를 지닌 다(p>0.05). 2. Movement, overall behavior는 전날 수면 시간에 따라 유의하게 반비례하는 상관관계를 나타냈다(p<0.05). 3. 치료 내용에 따른 진정 요법 효과의 차이는 보이지 않았다(p>0.05). 실험 결과 진정 전 수면 시간이 짧을수록 진정 효과가 높은 것으로 나타났다. Sedative method and its effect are affected by diverse variables: dosage and intake method of drug, weight, gender, patient compliance, sleeping hours prior to procedure, treatment hours, health status, type of used drugs are the factors. This study is conducted with empirical observation that shorter the sleeping hours before the day of chloral hydrate sedation, the effectiveness is larger; and therefore to actually recognize the correlation between chloral hydrate/hydroxyzine sedation and sleeping hours of child patient prior to sedation. The subjects were those children whose sleeping hours were similar to each other at the ages ranging from 2 to 5 years old totaling 37 children. Total 11 of them received pulp treatment. Sedative effect was evaluated by the same assessor with Houpt’s rating scale. Sedative effect in relation with prior day’s sleeping hours evaluated with simple regression analysis. Sedative effect in relation with pulp treatment was analyzed with independent t-test. Sleeping hours prior to sedation and sedation effect have negative correlation. No significant correlation is found between pulp treatment and sedation effect(p>0.05).

러시아 구축주의 미술작품과 조각을 모티브로 한 컨슈머 헤어 작품 연구

맹유진 ( You Jin Meang ) 한국미용학회 2008 한국미용학회지 Vol.14 No.4

Creative hair styling involves making a new hair style after interpreting an existing hair style in a personal manner, which needs to contain its own structure, image and meaning. Constructivism is a movement that took place in Russia from 1910 to 1920. One of its main characteristics is that the ideas of artists are expressed by using simple figures of diagrams. Although simplicity was emphasised in the constructivist arts, the spatial orientation and geometrical figures were outstanding. In this study, constructivist artists and their art have been analysed in order to find out the fundamental use of space, line and side. Subsequently, four consumer hair styles were created. The main aim was to create three dimensional hair styles by applying the constructivist use of space, line and side. A special attention was put on expressing the beauty of repetition of lines and sides, and arising geometrical beauty and spaciousness. It is hoped that this study and the consumer hair styles can offer a baseline of the formative arts in the consumer hair styling. More studies about the art trend could be made to elaborate more various and creative hair styles.

There has been a new wave of challenges, in a various ways, in the 1990s art, leading to Post-modernist works such as Dadaism, deconstructionism, minimalism and avant-garde in art, sculpture, architecture, literature and etc. These attempts have also made their effects on fashion and hair style in general, which emphasized creativities. The aim of this research is to carry out the more creative hair image work, adapting formatives and creativeness of Frank Gary`s architectures to the “beauty” art context. Background study has been carried out researching books, articles and internet, in order to analyse the characteristics of deconstructionism and Frank Gary`s architectures. In addition, the picture analyses have also been done so as to analyse the characteristics of the images of the architectures, leading to an empirical study. After having done the background study, the “Up-style” hair has been selected to express the organic features of that period of architectures. The great primitive forms such as cubes, cones, spheres and cylinders have been applied to illustrate the three-dimensional representation. One of the Frank Gary architectural features is the use of the complex curves, forming gently leading wave pattern. To apply the so-mentioned characteristic in the “Up-style” hair, the hair has not been coloured. Thus, the simple rhythms of lines have been emphasized. Accessories, made of felt, paper and ribbon, have been used to express simplicity and large swings.
