전하안면 고경이 작은 III급 부정교합자의 골격유형에 관한 두부방사선 계측학적 연구
한동헌(Dong-Hun Han),차경석(Kyung-Suk Cha) 대한치과교정학회 1996 대한치과교정학회지 Vol.26 No.2
부정교합의 특징을 파악하고 유형별로 분류하여 진단 및 치료에 적절히 적용함이 예후에 상당히 중요하다 하겠다. 안모의 유형은 여러 형태적인 특징이 상호 결합된 하나의 Syndrome으로 인식할 수 있으며 어느 특정한 계측항목만으로는 분류될수 없는 것이다. 전후방적인 부정교합의 구분이외에도 수직적인 부조화 양상을 함께 고려한 비교 연구가 다각적으로 시도되어지고 있으나 분류의 기준이 어느 한 특징 요소만을 강조하는 경향이 있어 여러 골격 유형이 혼합되어 분류, 비교 되어지는 단점이 있었다. 본 연구는 전하안면 고경이 작은 3급 부정교합에 혼재되어 있는 골격유형을 분류하고 각 유형간의 특징을 비교 분석하기 위하여 시행되어졌으며 단국대학교 부속 치과병원 교정과에 내원한 부정교합자중 혼합치열기이면서 전하안면 고경이 작은 3급 부정교합자를 선별하여 실험군으로 하여 다음과 같이 결론을 얻었다. 1. 전하안면 고경이 작은 3급 부정교합은 수직적인 양상을 따라 3가지 Subtype으로 분류할수 있다. 2. Subtype 1은 하악지가 크게 발육되 있는 것이 특징으로 후방 구치 치조부의 hypopiasia는 인정되지 않으며 전방위치하여 전하안면 고경이 낮아지고 하악하연 경사도가 뚜렷이 작아져 있다. 3. Subtype 2는 안모의 전반적인 수직고경이 작은 것이 특징으로 하악지 발육은 정상이거나 미약하고 후방 구치 치조부의 hypopiasia가 뚜렷하여 전하안면 고경이 작아지나, 하악하연 경사도는 정상범주를 유지한다. 4. Subtype 3은 안모의 전후 수직고경이 정상범주이나 전상안면이 전하안면보다 많은 비율을 점유하는 것이 특징으로, 하악지의 고경은 정상 범주이나 후방 구치 치조부의 hypopiasia가 인정되며 전하안면 고경이 작고 하악하연 경사도도 작게 나타난다. 5. 각 유형별로 그 특징을 반영하는 Discriminative indext는 다음과 같다. LAFH : 유형과 상관없이 전하안면 고경이 작은 경우를 충실히 나타내준다. FHR : PFH/AFH의 비로 큰 경우, subtype 1을 분별해 준다. FHI : RH2/IH의 비로 정상에 가까운 경우 subtype 2를 분별해 준다. FPI : (ALFH/ATFH - AUFH/ATFH)×100의 값으로 아주 작은 경우, subtype 3을 분별해 준다. 6. 각 유형의 차이는 기능적인 차이를 반영하는 것으로 사료되며 기능적인 차이를 확인하고 치료와 연관시키는 것이 중요하다고 사료되어진다. A given facial type can be considered as a syndrome in which various features are aggregated, so a single parameter is not sufficient to accurately identify a given facial type. This study was designed to identify & characterize the skeletal types that blend under the headline-´Cl III,deepbite´. Cephalograms of thirty-four untreated mixed dentition patients, selected mainly on the basis of clinical impression of CI III with reduced lower face heights were studied. The following conclusion can be drawn. 1. CI III malocclusion with reduced lower face height could be classified into three types. 2. Subtype 1 was identified by the following features : strong ramus, more anteriorly positioned upper molars without alveolar hypoplasia, acutely reduced Mn. plane angle. 3. Subtype 2 was characterized by a short ramus, sharply reduced postrior alveolar height, and normal Mn. plane angle. In general, this type had hypoplasia tendency in the vertical dimension. 4. In subtype 3, the AUFH occupying more percentage than ALFH was a outstanding feature. Ramal height was in normal range, alveolar hypoplasia and slightly reduced Mn. plane angle was observed. 5. The features of the subtypes were reflected in certain indices, which can be regarded as discriminative index. LAFH: if reduced, regardless of subtypes, indicates reduced lower ant. face height consistently. FHR: when this ratio is increased, it indicates subtype 1. FHl: when this ratio is in normal range, it indicates subtype 2. FPI: if reduced greatly, it indicates subtype 3.

Dental caries is multifactorial local disease which involves destruction of the hard tissues of the teeth by metabolities produces by microorganisms. Recently, there has been growing interest in the role of nitric oxide (NO) and glutathione (GSH) in caries incidence. The aim of the study was to survey the studies reported the association among salivary NO, GSH and dental careis. Three studies reported the association between NO and dental caries. However, the results were contradictory. Only one study showed negative association between GSH and dental caries. In Korea, NO showed negative association with Lactobacilli and GSH showed positive association with dental caries. These observations suggest the possibility that NO and GSH could be new biomarkers for dental caries. However, further study should be needed.

Purpose: The institutionalized elderly have placed the most vulnerable state, and the report about the oral health status of the institutionalized elderly was scarce. The aims of the current study were to investigate the oral health status of institutionalized elderly. Materials and methods: The survey of the oral health status was carried out on 487 institutionalized elderly from 4 longterm care facilities of Seoul metropolitan city, Gyunggi province, and Gangwon province in Korea. Results: The prevalence of dental caries, root caries, and dental calculus of the institutionalized elderly was 19.2%, 15.3%, and 23.7%, respectively. The percentage of edentulism among the institutionalized elderly was 26.2%. Those who had poor oral hygiene and tongue coating were 43.9% and 90.5%, respectively. The percentages wearing complete and removable partial denture on maxilla were 12.8% and 3.3%, respectively. The percentages wearing complete and removable partial denture on mandible were 7.8% and 5.6%, respectively. The percentages of institutionalized elderly needing complete and removable partial denture on maxilla were 29.7% and 27.2%, respectively. The percentages of institutionalized elderly needing complete and removable partial denture on mandible were 24.5% and 30.9%, respectively. Conclusion: The oral health stuatus of institutionalized elderly was poor. For the oral health promotion of elderly in longterm care facilities, it is essential to educate nurses and caregivers about the importance of the oral health and oral hygiene method.

Korean government enacted the 1st Basic Plan for Low Fertility and Population Ageing in 2005 due to the long-lasting ultralow birth rate. Based on the Act, Korean government set up a step-by-step strategic goal and establish a basic plan, every five years, to achieve the sustainable development of society corresponding to low fertility and aging society. Over the past decade, the 1st Basic Plan for Low Fertility and Population Ageing ( 2006-2010 ) and the 2nd Basic Plan for Low Fertility and Population Ageing ( 2011-2015 ) was executed. This year, based on the achievements and limitations of the 1st and 2nd Basic Plan, the 3rd Basic Plan for Low Fertility and Population Ageing begins. In this manuscript, I discuss the background of the 3rd Basic Plan and its significance in oral health area.

South Korea’s oral health care non-governmental organizations (NGOs) have played a crucial role in South-North relations, although a formal intergovernmental relationship is difficult to establish and also easily breaks down. Humanitarian assistance by NGOs in the oral health care sector is an area that receives wide support from South Korean society for its urgency and for its appeal to humanity. This humanitarian assistance started in the late 1990’s and continued to grow until the late 2000’s. This assistance continued throughout the tension between the two administrations that resulted in a radical decrease in overall assistance from South Korea to North Korea. However, concerns remain about the transparency and efficiency of NGO activities. In this article, the NGOs and their major activities are delineated, and South Korean legislation is examined. A current act, the Law on the Development of South and North Korean Relations serves as a basis for governmental regulation and support of NGO’s. Humanitarian assistance in the oral healthcare area is directly related to the oral health of the North Korean people, and it should not be influenced by political changes. Long-term planning and close discussions between NGOs, their North Korean counterparts, and the South Korean government are needed. NGOs need to overcome their shortcomings such as a lack of expertise and shortage of financial support. For this, NGOs must improve their administration transparency and professionalism.
