Objectives : This study is to examine the effectiveness in the oral health promotion through the oral health education for high school students. In adolescence, there seems to be the high incidences of dental caries, gingivitis and periodontal diseases. Concerning preventing all such outbreaks, this study focuses on applying the oral health education to their health education, and on analyzing its effectiveness. Methods : To verify its effectiveness, this research administered 85 students of both genders of a certain high school in Seoul during May-October 2010, followed by the evaluation of DMFT, S-PHP, and CPITN. Results : First, the oral health promotion through the education was statistically significant in the permanent effects of index (FT index). Second, the effect of S-PHP index gradually decreased in statistics from the first to the fifth session, but, after five months ever since the education, it seemed relatively higher in the next sessions. Third, the changing in the level of CPITN decreased continuously as the students received the education repeatedly, but there is no significant difference in statistics for each session. Conclusions : For the oral health promotion in the high school students, the education ought to be focused on the behavior-change objectives rather than on the knowledge-based objectives. The repeated education for tooth-brushing instruction should be stressed for preventing from returning to the old bad behaviors.

Periogen은 실시간 PCR 방법을 이용한 우식활성 검사법으로, 치아우식 유발균에 대한 정량적인 분석을 통해 개개인의 치아우식 위험도를 평가한다. 이 연구는 소아에서 Periogen과 치아우식 경험 지수(dmft, dmft indices)와의 상관성을 평가하고, 기존의 치아우식 위험 검사법인 Cariview, 치아우식 평가 도구(Caries Assessment Tool)와 비교할 목적으로 시행되었다. 만 6세 미만 83명의 소아를 대상으로 실험이 진행되었다. 시진을 통해 치아우식 경험 지수(dmft, dmft indices)가 기록되었으며, 간단한 설문 조사를 통해 CAT 평가 시행되었다. Periogen, Cariview는 제조사의 지시에 따라 치아우식 위험도 평가 시행되었다. 그 결과 Periogen, Cariview 그리고 CAT는 dmfts index와 상관계수가 각각 0.38, 0.56, 0.66을 보여 모두 중등도의 상관관계를 보였다(p < 0.01). Periogen, Cariview 그리고 CAT의 민감도와 특이도 분석의 경우, 민감도는 각각 43%, 76%, 95%를 보였으며, 특이도는 각각 80%, 72%, 74%를 보였다. ROC 곡선의 곡선하면적(AUC)는 각각 0.69, 0.81, 0.85를 보였다. Periogen의 경우 다른 기존의 두 가지 검사법에 비해 치아우식 위험도 평가에 있어 더 낮은 유효성을 보였다. 따라서 임상적으로 사용되기 위해서는 더 나은 유효성을 위한 개량이 필요할 것으로 보인다.

This study was to promote the business of school dental health program in community area and to present the improvement of oral health between public health center's group of SungDong elementary school, one that started on March 1999, and the control group that is going to operate school oral health center from 2009 in primary school. It was based on the data of more than 10 years running school based oral health section. We compared the data of SungDong group with the one of control group to get a survey of dental caries experience. The preventive effect of the caries was estimated by the difference of DMFT indices between the sample group and control group. The experience rate of caries of the sample was 12.6 percentage lower than the control group and index of the experience rate of caries for the SungDong group was two times less. It showed that the sealing rate of the SungDong group composed of pit and fissure sealant was 67.7 percentage high. The prevention rate which was calculated by DMFT index was 46.34 percentage in the SungDong group that was the highest score for the fifth grade student as a 60.5 percentage. This program contributes to the improvement of the dental caries reduction in this school oral health promotion program.

Objectives: Dental caries and periodontitis are major oral bacterial infections associated with dental plaque. Infection and inflammation play a role in carcinogenesis, and a significant link has been found between some highly prevalent oral and dental diseases and some types of cancer. Therefore, the aim of this study was to evaluate the relationship between cancer and oral health among Korean adults. Methods: Data from the 6th Korea National Health and Nutrition Examination Survey were used to analyze the incidence of cancer according to oral health. Demographic and socioeconomic statuses and oral behavior of the participants was analyzed using complex chi-square tests. Logistic regression was used to analyze the relationship between a high DMFT index and cancer by calculating the 95% confidence intervals. Results: In total, 6,450 case-control subjects were included. Significant difference was observed in the DMFT index, but not in periodontal diseases, between the cases and controls. The odds ratio for cancer was 1.80 (95% confidence interval: 1.18 to 2.73) in the high-risk group. However, no significant difference was observed after adjusting for age, education level, and income. Conclusions: The results provide potential evidence of a significant association between cancer and oral disease.

Background: This study was aimed at reducing depression and improving the quality of life and oral health of the elderly Koreans by elucidating the effect of depression on their life quality and oral health. Methods: Original data from the 8th National Health and Nutrition Survey (2019) were analyzed and implemented. The elderly (age≥65years) Koreans were enrolled. The oral health status was determined using the Decayed, Missing, Filled Teeth (DMFT) index and subjective self-report. The quality of life was quantified as the sum of score of each item in the Euro Qol-5 dimension (EQ-5D) and Health-related Quality of Life Instrument with 8 Items (HINT-8). The t-test, one-way analysis of variance, correlation analysis, and multiple regression analysis were performed to statistically compare the quality of life, oral health status, and oral health status according to the depression status. Results: EQ-5D and HINT-8 scores differed significantly with the history of depression, current depression, stress perception, depression for 2 weeks, and annual suicidal intention (p≤0.05). The DMFT index score differed significantly with the depression diagnosis and depression for 2 weeks (p≤0.05). EQ-5D, HINT-8, and DMFT index differed significantly with all oral health behavior variables (p≤ 0.05). Conclusions: The results of this study could serve as a basis to formulate oral health programs for the elderly to reduce depression and improve the quality of life.

Objectives: This study investigated the relationship between obesity and dental caries of Korean adolescents. Methods: Data from the Korea National Health and Nutrition Examination Survey (KNHNES VI) (2013 to 2015) were used and targeted adolescents aged 13 to 18 years. For statistical analysis, the SPSS 18.0 program was used, and the significance level was set at 0.05. Results: For the general and health-related characteristics, female students (p=0.001) showed higher decayed, missing, and filled teeth (DMFT) index than male students. Furthermore, DMFT showed higher tendency, as age was higher (p<0.001). Smoking (p=0.011) and drinking experience (p=0.027) revealed higher DMFT. The dental caries experience was significantly different among students who were female (p=0.033), older (p=0.001), and overweight or underweight (p=0.022). In the BMI for the general and health-related characteristics, male students had higher obesity rate than female students (p=0.003), and obese subjects had higher dental checkup in the last year (p=0.013). In multiple linear regression analysis of obesity and DMFT, the unadjusted model showed that the obesity group's DMFT was about 0.8 higher than that of the normal group (p=0.024). However, statistical significance was not shown in the adjusted models. In the logistic regression analysis of obesity and dental caries experience, the unadjusted model 1 (1.93 times), the adjusted model 2 (1.79 times), and model 3 (1.76 times) showed significantly higher dental caries experience. Conclusions: Both obesity and dental caries are related to diet habits and lifestyles and have a negative impact on adult health. Therefore, it is necessary to create a healthy social environment around the adolescent, and proper intervention through education is required to form healthy habits.
