Objectives: This purpose of this study was to examine the trends in interventional research and analyze the contents and results of intervention through a systematic literature review of the domestic research literature, suggesting the effect of an oral care program on elementary school students. Methods: A total of 262 articles were retrieved initially, and the duplicate articles were then removed, excluded after screening titles, abstracts, and full-text articles. Finally, a total of 16 papers were used in the review. Results: The study included 9 articles with the nonequivalent control group pretest-posttest design and 7 with the one-group pretest-posttest design. All articles were of non-randomized studies. The most common index of the interventional effect was dental plaque. Further, oral health behaviors and knowledge, perception, self-efficacy, and DMFT index were common indices. In the quality assessment, in the "blinding of outcome assessment" among six items of ROBANS, 12 studies showed a high risk of bias. Conclusions: In order to develop an interventional oral health care program for elementary school students and evaluate the effectiveness, a strict research design and qualitative improvement of research reports are required, and continuous research should be conducted to develop a systematic protocol.

The author extracted 300 children as a control group and 300 children as an observation group from Korean primary school children which were aged 9 to 11, and surveyed the dental caries experience and oral hygiene condition. Children in a control group had not been served wit school meal. On the other hand, children in an observation group were served with school meal. The average number of caries experienced permanent teeth per mouth and the oral hygiene indices were calculated from the collected data and compared with each other. The obtained results were as follows. 1. The DMFT rate was 15.93% in the observation group and 10.33% in the control group. 2. The Oral Hygiene Index was 1.04 in the observation group and 1.60 in the control group. 3. It couldn't be made a decision that school meal service was direct cause to increase the occurrence of dental caries on the permanent teeth in Korean primary school children.

This study was conducted to identify actual dental care status, levels of knowledge, attitudes, and behaviors about dental health, and dental health conditions in elementary students; and examine the relationships between the levels of knowledge, attitudes, behaviors, and dental health conditions for 427 students in their sixth grades from six elementary schools in Pusan area from November 1st to December 5th, 2002. The data was collected through a structured study questionnaire and through dental checkups by dentists and was analyzed into frequency, percentage, mean, standard deviation, t-test, one-way ANOVA and Pearson's correlation analysis using SPSS program. The main results of this study were summarized as follows： 1) The levels of knowledge, attitudes, behaviors about dental health was found to be high as mean score 18.75 points (64.7％) in knowledge, 17.86 points (59.5％) in attitudes, and 31.64 points (67.3％) in behaviors. Therefore they were found to care a lot about their dental health. The indices of dental health conditions were found to be low as mean score 0.87 pieces (3.1％) of treated teeth, 1.27 pieces (4.5％) of teeth to be treated, 7.64％ of the DMFT rate and 0.43 points (7.2％) of the simplified oral hygiene index. Therefore their condition of dental health was found to be very clean. 2) The relationships among the knowledge, attitudes, and behaviors about dental health showed a weak level of positive correlations. Among the conditions of dental health, treated teeth and the DMFT rate showed a moderate level of positive correlation； and treated teeth and the simplified oral hygiene index showed weak level of positive correlation. 3) The condition of dental health of the subjects of this study was found to be good and dental care was properly done when there was participation of parents and school health educators in dental care. It tells us that dental education is required not only for children but also for their parents. As there were significant correlations between knowledge, attitudes, and behaviors about children's dental heath, school health educators should encourage students to have continuous dental care habits for lifelong dental health with repetitive education, rather than to deliver simple knowledge to students during dental health education.

Purpose: The aim of this study was to confirm the validity of the $Cariview^{TM}$, test in adults by assessing correlations between $Cariview^{TM}$, scores and caries experience using a quantitative light-induced fluorescence (QLF) technique. Methods: This retrospective cross-sectional study included 111 patients aged 19-64 years who visited a dental clinic in Seoul from 2015 to 2016, and underwent the $Cariview^{TM}$, test and had their teeth photographed with the Qraycam. Plaque was scraped with sterilized cotton swabs, and then placed in a culture medium and incubated at $37^{\circ}C$ for 48 h. Finally, the degree of color change was evaluated, and scored on a 0-100 point scale. Caries experience index included not only cavitated lesions but also early caries that were detected on white and fluorescence images. Participants were divided into low, moderate and high caries risk groups according to the $Cariview^{TM}$, score, and caries experience was compared between risk groups using ANCOVA. Spearman correlation coefficients were calculated to analyze the associations between $Cariview^{TM}$, scores and caries indices. Result: The mean age of the participants was 40 years, and the mean $Cariview^{TM}$, score was $53.6{\pm}20.7$. The WDMFT and the DMFT indices significantly increased with caries risk, and this increase was significantly different between the low- and high-risk groups. The $Cariview^{TM}$, test scores were significantly correlated with the WDMFT (r = 0.28, P = 0.003) and DMFT (r = 0.29, P = 0.002) indices. Conclusion: The $Cariview^{TM}$, test could be a clinically useful and simple method for assessing caries risk in adults.
