Objectives. This study examined the characteristics of a high caries risk group of 12-year-old children in Korea. Methods. The oral health status and interview data were collected from 1,755 children (888 males, 867 females), aged 12 years, who participated in the Korea National Oral Health Survey in 2006. The DMFT values of the subjects were sorted. The upper one third was selected as the high risk caries group (N=585) and the other two thirds were classified as the low risk caries group (N=1,170). This study used the demographic and social variables, such as gender, area of residence and governmental support for lunch in school. The variables for the oral health status, oral health related-consciousness and behavior were the number of dental sealants of the first molar, self-perceived oral health, tooth brushing after lunch, average frequencies of tooth brushing per day and the mean frequency of daily snack consumption. The associations between the demographic and social variables, oral health status, oral health related-consciousness and behavior and high risk group were evaluated by logistic regression analysis. Results. Most of the high caries risk group had less than 2 sealant teeth on the first molar (94.2%) and lived mainly in metropolitan areas (46.8%, p<0.05). They had a poorer self-perceived oral health (41.8%) than the low risk group and more 2∼3 times the snack intake per day (p<0.05). The determinants of the high risk group were whether the first molar was sealed (‘under 2’, OR=6.05), self-perceived oral health (‘good’, OR=1.77, ‘poor’, OR=2.67), mean frequency of daily snack intake (‘2∼3 time’, OR=1.31, ‘more than 4’, OR=2.34) and area of residence (‘city’, OR=0.79). Conclusions. The characteristics of the high caries risk group in Korean 12-year-old children were less than 2 sealant teeth on the first molar, poor self-perceived oral health, high snack intake per day and living in metropolitan areas.

Korea has been managed HACCP with food and livestock products separately, but it was incorporated into food and livestock product safety management certification standard in 2015. Currently, the notification is unified, but food sanitation act and the livestock products sanitary control act are not unified. These differences are leading to complaints from food and livestock corporation. In this review, the food sanitation act, enforcement regulations of the food sanitation act, the livestock products sanitary control act and enforcement regulations of the livestock products sanitary control act were compared and analyzed to identify the part which requires unification. As a result of the survey, the thirteen clauses were proposed to unify in the food sanitation act and the livestock products sanitary control act. The nineteen clauses were proposed to unify in enforcement regulations of the food sanitation act and enforcement regulations of the livestock products sanitary control act.

Background: The purpose of this study was to analyze the equality between key words used in the Journal of Korean Dental Society of Anesthesiology and Medical Subject Headings (MeSH). Methods: A total of 666 English key words in 187 papers (average 3.5 words in a paper) from 2001 to 2014 were eligible for this study. We classified them according to matched, and non-matched terms. After descriptive analysis, we assayed patterns of errors in using MeSH, and reviewed frequently used non-MeSH terms. Results: Fifty nine point six percent (59.6%) of total key words were completely coincident with MeSH terms, 40.39% were not MeSH terms. Conclusions: The results show that the coincidence rate of key words with MeSH terms was at a moderate level. However, there is a need for us to understand MeSH more specifically and accurately. Use of proper key words aligned with the international standards such as MeSH is important to be properly cited. The authors should pay attention and be educated on correct use of MeSH as key words.

안소연,김아현,심연수,김민정,An, So-Youn,Kim, Ah-Hyeon,Shim, Youn-Soo,Kim, Min-Jeong 대한턱관절교합학회 2013 구강회복응용과학지 Vol.29 No.1

T4K는 혼합치열기의 2급 부정교합 환자에게 사용되는 기능성, 가철성 교정장치이다. 기능성 교정장치의 경우 치열과 악골의 성장에 영향을 주는 구강안면부의 근육의 부조화를 개선시키는 역할을 한다. T4K에 포함된 lip bumper는 과도한 하순의 힘을 차단하여 주고, 하순 내측 전정을 자극하는 요소가 포함되어 있다. 부적절한 혀의 위치를 교정할 수 있는 요소는 환자들이 장치를 장착하는 동안 부가적인 혀 운동을 할 필요성을 감소시킨다. 2급 부정교합 환자의 경우 하악 열성장을 동반하는 경우가 대부분을 차지한다. 이 장치는 상악 치아를 고정원으로 하여, 하악을 전방으로 성장할 수 있도록 자극하여 부족한 하악 성장을 촉진하는 역할을 하고 있다. 이와 함께 부가적으로 Labial bow와 같은 역할을 하는 요소는 상악 치열의 개선에 도움을 준다. T4K는 기성품으로 작은 부피와 부드러운 질감으로 어린 환자들의 장착 동의율을 높이는 데 장점을 가진다. 원광대학교 치과대학 산본치과병원 소아치과에 내원한 혼합치열기의 2급 부정교합 환자에서 만족스러운 결과를 얻었기에 이를 보고하는 바이다. 요약 1. T4K를 혼합치열기의 2급 부정교합 환자에게 사용하여 안모의 개선을 얻었다. 2. 과도한 수직, 수평 피개교합이 개선되었다. 3. 하악 열성장 환자에서 T4K를 장착하여 하악 성장을 촉진하는 결과를 얻었다. 4. 구호흡 등과 같은 구강악습관의 개선을 얻었다. $T4K^{TM}$(Myofunctional Research Co, Australia) is one of the myofunctional appliance developed to be used in children of mixed dentition. Myofuncitonal appliance stimulate the facial, masticatory and tongue muscle and help to balance the muscular force. Labial bow included in the device exerts strength in excessively labial inclineded upper jaw, Lip bumper blocks strength of the mouth to prevent abnormal strength exerted in lower jaw, Tongue tag secures proper position of tongue, and additional exercise is not required for child patients. For the more, simpler design and softer texture of device prmoted cooperation of patients during use. This case report is to present the satisfactory results gained by using $T4K^{TM}$ on Class II patients. Comment 1. $T4K^{TM}$ was applied in Class II malocclusion patients of mixed dentition with expected space insufficient to gain facial improvement. 2. Excessive overjet, overbite were improved. 3. Main effects are regarded to have been achieved by development of lingual slant of upper jaw, labial slant of lower jaw, and lower part of jawbone. 4. Bad habits, such as mouth breathing, can also be adjusted.

The objective of this study was to evaluate the quality-based characteristics of Prunus mume fruit syrup, which is manufactured with various sugared sweeteners for suggestion of suitable alternative sweetener. Sweetener such as sucrose (MHP1), crystalline fructose (MHP2) and liquid fructo-oligosaccharide (MHP3) are used to manufacture Prunus mume fruit syrup. The sugar content of MHP1, MHP2 and MHP3 showed 53, 54 and $36^{\circ}Brix$, respectively. The total organic acid content of MHP1, MHP2 and MHP3 was 2.22, 3.07 and 3.71%. The total free sugar content of MHP1, MHP2 and MHP3 was 54.39, 47.52% and 31.62%, respectively. The appearance of MHP1 and MHP2 remained unchanged for the entire period but MHP3 had molded since the first week. This was as a result of the low total free sugar content in MHP3 sugared with liquid fructo-oligosaccharide compared to MHP1 and MHP2 sugared with solid sucrose and fructose. The sensory characteristics of MHP2 manufactured with crystalline fructose indicated an above average quality, indicating that it is difficult to manufacture Prunus mume fruit syrup using liquid sugar. It is suggested that crystalline fructose characterized solid form and lower glycemic index than sucrose be useful to manufacture Prunus mume fruit syrup as alternative sweetener.

본 연구에서는 중학생을 대상으로 치과치료에 대한 치과공포도와 요인을 조사함으로써 치과의료 관리측면에서 활용하는 기초 자료를 연구하고자 수행되었다. 청주시 소재 1개 중학교를 편의 추출하여 2011년 12월 19일부터 일주일 동안 자기기입식 설문조사를 실시하였고, 설문 결과 치과 방문 경험이 있는 475명중, ‘치과 방문 시 공포를 느낀 적이 있습니까?’라는 문항에 ‘예’라고 대답한 남학생 77명, 여학생 169명, 총 246명의 자료를 이용하였다. 각 공포 원인의 범주별 답변의 분포를 알아보기 위해 빈도분석을 실시하였으며, 분석 방법은 남녀별 응답의 차이를 검정하기 위해 교차분석과 범주별 공포점수의 비교를 위하여 독립표본 T 검정을 실시하였다. 연구 결과 ’치과 진료 시 자극 유발’의 범주의 문항에서 남녀 간의 차이가 존재하였다(p<0.05). 각 문항의 답을 점수화 하여 공포도를 점수로 환산한 결과에서 남학생은 평균 52.0점, 여학생은 평균 58.53점으로 여학생의 점수가 남학생에 비해 통계적으로 유의하게 높은 것으로 나타났다. 그리고 범주별 공포도 점수는 ‘치과 진료 시 자극 유발’의 범주에서 여학생이 남학생보다 통계적으로 높은 공포도를 보이는 것으로 나타났다(p<0.05). 따라서 이러한 결과를 치과 진료 환경에 반영하여 청소년들의 치과 공포를 줄일 수 있도록 하는 배려가 필요하다. This study aims to examine the level of fear and the influential factors affecting their dental fear and to utilize the result as the basic materials in the dental management. The subjects were the students from a middle school located in Cheongju-City. The school was selected by convenient sampling and self-answered questionnaire was filled in by the students for a week from December 19th 2011. The survey result showed that 77 male students and 169 female students(total 246 students) answered ‘yes’ to the question ‘Have you ever felt fear when you visited a dentist?’ among 475 students who had visited a dentist in the past. The distribution of responses in each category of fear was examined by frequency analysis. The study results showed significant difference in the item of ‘causing irritation during the dental treatments’ between male students and female students (p<0.05). Converting the level of fear into scores after marking the answers, the score of male students was 52.0 points and the score of female students was 58.53 showing the score of female students was significantly higher in statistics. Moreover, the fear score of female students for the category ‘causing irritation during the dental treatments’ was also significantly higher in statistics(p<0.05). Therefore, these results should be reflected to the dental care environments in order for the adolescent to reduce the dental anxiety and fear.
