This study used 3 kinds of experimental toothpaste prepared with different contents of SLS, i.e. A (0%), B (1.1%), C (2.2%). These 150 subjects were subdivided again into three groups. After 4 weeks application of the three kinds of toothpaste, it was found that there were differences in dental plaque test (PHP) among the 3 groups; that is; a higher SLS content was associated with a lower PHP index. In addition, it was found that all 3 groups showed a reduction in simplified oral hygiene index (OHI-S). After 4 weeks application of the three groups of toothpaste, it was found that a higher SLS content was associated with a lower salivary flow, but there was no significant variation in salivary mucosity and pH. Further, it was found that SLS was negatively correlated with salivary flow, which supports the theory that SLS may induce xerostomia.

Objectives: The purpose of the study is to investigate the subjective oral status perception and OHIP according to the oral health managementamong international and domestic university students. Methods: self-reported questionnaire was completed by 176 domestic and 175 international university students in Daegu and Gyeongbuk from August 25 to November 1, 2014. The informed consent was received after explanation of the purpose of the study by the researcher. The questionnaire consisted of general characteristics of the subjects, toothbrushing behavior, oral health management, subjective oral status perception. and oral health impact profile (OHIP). The subjective oral status perception and OHIP was measured by Likert 5 point scale. Results: The international students tended to have higher subjective oral status perception when they had longer stay with the roommate in Korea. The female international students tended to have higher OHIP than the male students. The domestic students with lower grades and roommates showed higher OHIP. The international students had a poorer practice of oral health management than domestic students. The overall mean of subjective oral status perception was 3.13 in domestic students, and 3.09 and 3.22 in international students. The overall mean of OHIP was 4.21 in domestic students and 4.25 and 4.16 in the international students, Conclusions: International students had a higher subjective oral status perception than domestic students, but their wrong oral health management lowered their quality of life. It is necessary to provide the oral health management for the international students continuously.

Objectives: This study involved a non-equivalent control group, pre-test/post-test measurement experiment to evaluate the efficacy of distributing plaque disclosing agents to healthy adults living in South Korea and promoting its self-application. Methods: O'Leary index, PHP index, oral health behavior intention, and oral care satisfaction were used as research tools. A notice was posted on the bulletin board from September 12 to October 15, 2016, to recruit adults aged 20-50 years. Data were analyzed using SPSS Version 22.0, and frequency analysis, Pearson's chi-squared, one-way analysis of variance (ANOVA), Kruskal-Wallis, and repeated measures ANOVA were performed. Results: The O'Leary index was significantly reduced in the group (p<0.01), and time (p<0.01) after education and width of the decrease had the highest score in the group that received education on plaque disclosing only. They were followed by the group that received education on plaque disclosing and the rolling method, the group that received education on the rolling method alone, and the control group. The PHP index significantly decreased in the group(p<0.01) and time (p<0.01), and the group time (p=0.039) after education, and width of the decrease had the highest score in the group that received education on plaque disclosing and rolling method. They were followed by the group that received education on plaque disclosing alone, the group that received education on the rolling method alone, and the control group. Conclusions: Based on the aforementioned findings, the direct use of plaque disclosing had a marked effect on self-oral care. These results suggest that the self-application of plaque disclosing could be an effective self-care method for improving the oral environment.

Daejeon school-based toothbrushing program using toothbrushing room started at 2007. Ministry of Health and Welfare started national toothbrushing room program without pilot project at 2011. The aim of this study was to provide the basic data to assess of the effect of this program. 59 experimental subjects and 60 control subject were selected after written consent. Oral Examination was done by 1 dentist using WHO standard and Survey of Child Oral Health-Related Quality of Life(COHIP), oral health knowledge and oral health behavior were done using self-registration form. We analyzed the result after adjusting economic status and subjective for the difference between experimental and control groups using SPSS 19.0. The experimental group had lower plaque index, better COHIP and more oral health knowledge significantly(p<0.05). But, The significance was not found in dental caries index and oral health behavior. We suggested the oral health education program and other dental caries prevention program including sealants were needed to prevent dental caries, although school-based toothbrushing program could improve COHIP.

The purpose of this study was to examine correlation between smoking and gingivitis in boy students targeting 281 students in the 2nd grade for vocational boys' high schools where are located in Cheongju city. As a result of carrying out questionnaire research and oral examination, the following conclusions were obtained. 1. The smoking-experience rate in subjects of this study accounted for 59.4%. The current smoking rate was indicated to be 41.3%. Students' average gingivitis prevalence accounted for 61.5%. Out of those students, the students with experience of smoking accounted for 44.8%. The average gingivitis index was $0.20{\pm}0.27$. Out of those students, the students with experience of smoking were indicated to be $0.29{\pm}0.31$. 2. In case of having experience of smoking, the probability of having gingivitis was high(p = 0.000). The more drinking experience led to the higher gingivitis prevalence(p = 0.010). 3. In the multi-variate analysis, a case of gingivitis prevalence was higher in the group with experience of smoking by 5.5 times(p = 0.000) compared to the non-smoking group. A case that the smoking volume for a day is over 6 pieces was higher by 8.4 times(p = 0.000) compared to the non-smoking group. A case of being over 25 months in the smoking period was higher 13.2 times(p = 0.000) compared to the non-smoking group.

The purposes of this study were to investigate the factors affection the Oral Impacts on Daily Performances for Children (C-OIDP) in elementary and middle school students, and identify the association between oral health-related behaviors, oral health condition and C-OIDP. A cross-sectional study was conducted in three schools in Incheon, Asan, Korea. A total of 175 selected children were interviewed by a trained examiner using a questionnaire. Oral Health Related Quality of Life was assessed by the Korean version of C-OIDP. Socio-economic characteristics, oral health-related behaviors, oral health condition and C-OIDP were verified using the questionnaire. ANOVA analysis was performed to determine the oral health and C-OIDP, and multiple regression analysis was performed to determine the factors affecting the C-OIDP. The activities with the greatest effect were eating (28.0%), cleaning teeth (22.9%), and smiling (18.9%). In the logistic regression model, the high item score of C-OIDP was associated with experiencing dental caries and gum pain in the past month. The more the C-OIDP prevalence item, the more the fillng deciduous tooth surface (fs) (p=0.024), caries experienced deciduous tooth surface (dfs) (p=0.049), total caries tooth surface (ds+DS) (p=0.021), and total caries experienced tooth surface (dfs+DMFS) (p=0.047). It can be concluded that the factors affecting C-OIDP are fs, dfs, dfs+DMFS, and gingival pain. Based on these results, we can improve C-OIDP to advance preventive practice.
