  • 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.

  • Periogen is a new caries activity test using real-time polymerase chain reaction. The aim of this study was to assess the validity of Periogen by evaluating the correlation with dmft, dmfts indices and comparing with Cariview and caries risk assessment tool (CAT). 83 children under 6 participated in this study. Dmft, dmfts indices and CAT were collected through an examination of oral health status. Plaque samples for Periogen and Cariview were collected and manipulated according to the manufactures' instructions. The correlation coefficient of Periogen, Cariview and CAT with the dmfts index were 0.38, 0.56 and 0.66 in each (p < 0.01). The sensitivity of Periogen, Cariview and CAT were 43%, 76% and 95% and specificity were 80%, 72% and 74% respectively. Area under curve under the receiver operating characteristic curves in each method indicated 0.69, 0.81 and 0.85. CAT and Cariview were more effective in evaluation the risk of dental caries than Periogen so far. To be used Periogen clinically, more improvements for higher validity were needed.

  • 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.

  • This study was conducted to examine the relations of oral health relevance to disabilities according to the relationship types between them and their guardian. The guardians were surveyed using self-writing questionnaires regarding the cohesion and communication process, and the oral health of disabled was analyzed by evaluation table. Total 78 copies were analyzed. SPSS win. 24.0 statistical program was used and the significance level was verified at .05. There was significance in the communication process(p<.01) according to the type of relationship with the disabled and their guardians. In oral health of the disabled according to the type of relationship with their guardians, there was significance in DMFT index(p<.01), first molar soundness(p<.01) and Pocket depth(p<.01).Therefore, the mother had a positive effect for the disabled on most items such as cohesion, communication process, and oral health. However, it is expected that policy support and research to increase the interests in oral health care management are needed for personal assistants, who showed a low impact on the cohesion, and communication process with disabled persons, and spouses, who showed a low influence on oral health of persons with disabilities.

  • For the detection of the active cariogenic factors contributing to caries development, some practical methods such as the Snyder test, estimation of salivary flow rate and salivary buffering capacity test were evaluated statistically by comparing DMFT and DMFS indexes. Total 122 children (62 male and 60 female ; 64 rural and 58 urban) were selected ramdomly from the 6th grade of the primary school and their salivary cariogenic factors were analysed and evaluated. Among the total 122 children, 78.7% was positive in the snyder test in which the marked, moderate and slight caries activities were 29.5%, 30.3% and 18.9%, respectively. In the Snyder test, 74.45% was positive in urban children while 84.48% was positive in rural children. DMFT and DMFS indexes were markedly lower in negative group than positive group of the Snyder test (p<0.01). The mean and standard deviation of stimulated salivary flow rate was 6.97$\pm$2.57 in male and 6.34$\pm$2.54 in female but no significant difference was observed in sexuality. The stimulated salivary flow rate of urban children was slightly higher that of rural but there was no significant difference between them. However, the group that showed below average in the stimulated salivary flow rate was markedly higher in DMFI and DMFT indexes than the group of above average. The mean and standard deviation of stimulated salivary buffering capacity was 7.65$\pm$2.19 in male and 6.80$\pm$1.67 in female. This difference was significant statistically(p<0.05). Stimulated salivary buffering capacity of urban children was higher than that of rural. Increases in stimulated salivary flow rate and buffering capacity had reduced the onset of dental caries of 14-year-old permanent tooth.
