Aim of this study was to confirm the effect of teaching and learning methods on outcomes of learner according to learning style. For this, 22 of dental hygiene students(case group) was treated teaching & learning methods according to learning style while 24 of students(control group) was non treated. Pre-survey were performed before performance of program. Formative Evaluation(FE) was conducted in 2, 3 and 4 week of program respectively and summative evaluation(SE), survey of subject interest(SI) and learning motivation(LM) were conducted in 5 week. The result of study, FE, SI and LM after treatment were increased than before treatment in case group(p<0.05). SI and LM of case group were higher than control group(p<0.05). FE after treatment was increased than before treatment in he assimilator(p<0.05). SI and LM of case groups were higher than control group in assimilator and diverger(p<0.05). The result of correlation analysis, SI was related with SE, FE, LM(p<0.01, p<0.05). Thus, it is necessary to development, application and study of teaching & learning consider to learning style.

The purpose of this study is to identify the convergence relationship regarding the effects of oral health behaviors on oral health related quality of life after conducting a self-reported survey by the convenience sampling method for 135 Vietnamese international students at J University located in JeonBuk region for 118 people excluding 17 who didn't respond well. In terms of oral health related quality of life according to oral health behavior there was a statistically significant difference in whether or not dental calculus removed over the past year(p<0.05), as a result of analyzing the effect of oral health behaviors on oral health related quality of life over the past year whether or not dental calculus removed was no(p<0.05), in the toothbrushing method it was found that the upper and lower(p<0.05) had a significant effect on oral health related quality of life. As a result it was found that some oral health behaviors affect the oral health related quality of life and it is thought that it can be used as basic data for improving the oral health of foreign students and the oral health related quality of life.

The purpose of this study was to examine the relationship between the working posture and symptoms of musculoskeletal disorders of dental hygienists during scaling. The subjects in this study were 264 selected dental hygienists. A convergence study was implemented using questionnaire that was prepared to cover general characteristics, health care, the work of scaling, working posture and subjective musculoskeletal symptoms. As for data analysis, R 2.15.1 was employed. As a result of analyzing the collected data, the rate of good working posture during scaling stood at 29.9 percent; roughly good posture, at 37.5 percent; incorrect posture, at 32.6 percent. Regarding the area of the body in which they complained of musculoskeletal symptoms, the shoulders were 3.32-fold more mentioned than any other area(OR,3.32;95%CI, 1.58~6.98); the foot, 2.97-fold more(OR,2.97;95%CI, 1.18~7.48); the hands, 2.84-fold more(OR,2.84:95%CI, 1.35~5.98); the neck, 2.82-fold more(OR, 2.82;95%CI, 1.35~5.91); the back, 2.41-fold more(OR,2.41;95%CI, 1.02~5.68). The findings of the study that demonstrate the importance of good working posture are expected to make a contribution to the improvement of work environments, the development of efficient preventive programs and the preparation of sustained educational plans, and it's necessary in the future to make a research study by including psychosocial factors.

This study evaluated the relationship between drinking and smoking and periodontal disease in Korean elderly people using 2013-2015 National Health and Nutrition Survey. (OR) 1.50; 95% confidence interval [CI], 1.00-2.24) than the non - alcoholic and non - smoking groups. The odds ratios were significantly higher. The odds ratios of periodontal disease were significantly higher in the elderly who were drinking and smoking at the same time than those who did not drink or smoke at all. This study confirms that drinking and smoking are significantly related to periodontal disease. Therefore, it is necessary to strengthen drinking and smoking cessation education to maintain oral health of the elderly.

This study aims to assess the relationship between obesity and dental caries in adolescents. Data were used from the 6th Korean National Health and Nutrition Examination Survey (2013-2015). Data analysis was performed using the SPSS Ver 22.0 program, and complex sample multivariate logistic regression analysis was performed to analyze relationship dental caries and obesity according to gender in adolescents. The subjects of this study were 1,243 adolescents aged 13 to 18 years. The relationship between obesity and dental caries in adolescents according to gender was not confirmed after adjusting for confounding variables.

A clinician's skills in a dental clinic are an important factor in removing the risk factors of patients. Although many universities have conducted educational programs, there has been a limitation on repeated practice because of the limited space and equipment. In dental radiography, there are various intraoral radiographic techniques. Since proficiency in radiography is an important factor in obtaining accurate radiographs, repeated practice and skill learning are important at the pre-clinical stage. However, the recent amendment of diagnostic radiation has caused difficulties in repeated practice on the human body. This study aims to develop a clinical simulator for intraoral radiography that enables repeated practice and self-directed learning without any restriction by utilizing the augmented reality technology to foster clinical skills for dental hygienist.

The purpose of this study was to antibacterial effect of solanum nigrum extra in candida albicans. In this study, the antibacterial effects of 70% methanol extract and solanum nigraum were investigated. The content of flavonoids and polyphenol contents in solanum nigrum extraction. The antimicrobial activity was determined by spectrophotometric growth inhibition assay(optical density) and colony forming untis (CFU) for the candida albicans. Total contents were flavonoids and polyphenols of solanum nigrum, the result was $8.23{\pm}0.13mg/g$ and $14.97{\pm}1.58mg/g$, respectively. The CFU results showed lower CFU counts in the experimental groups compared to the control group. And the result of the bacterial viability was decreased in the experimental group. Therefore the extracts of solanum nigrum were found to have antimicrobial activity in candida albicans. From the these results, solanum nigrum extracts have a possibility to be a candidate for natural antibacterial components in dental products.

The subjects of this study were 273 high school students, research tool was structured, anonymous, self-administrated questionnaire. The data were analyzed using SPSSWIN version 18.0. Significant positive correlation was found between stress and sugar intake behaviors. Significant negative correlation was between stress and subjective oral health status and between sugar intake behaviors and subjective oral health status. Stress and sugar intake behaviors are related to oral health status. So it is very important to develop oral health program in order to improve eating habit and oral health status of high school students.

This study aims to analyze the relevance between oral health practices and oral discomforts of the elderly in an urban-rural area by surveying the elderly in welfare centers for the Elderly-continued oral health care program. The result shows that the elderly brush their teeth under regular oral care, and practice oral health life by scaling for the prevention of periodontal disease. Most of the elderly who drink alcohol have experienced implant care and tend to quit drinking after the treatment, and seemed to get their oral discomfort relieved. However, no relevance is found between implant experiences and social discomfort. Furthermore, the elderly who had bad breath expressed pronunciation, taste, pain and chewing discomfort, and social discomfort (P>.05). The educational level of the elderly did not have an impact on oral discomfort, but smoking, chewing and bad breath discomfort seemed to be related to social discomfort(P>.05). Therefore, since oral discomfort of the elderly causes social discomfort which decreases their quality of living, we recommend oral health departments of local governments to help the elderly maintain happy lives by continuing to study the practical use of reducing oral discomfort.
