Objectives: This study was conducted to analyze the dental care utilization patterns and related factors of the rural residents. Methods: The data collected by interview and self-administered questionnaire survey of 524 peoples of Seongju county in Gyeongsanbuk-do. The summarized results are as follows. Results: The rate of persons who experienced the oral disease was 52.5% during 1 year and it was at most in the age group of 40-49. The rate of persons who had experienced the oral disease were investigated according to general characteristics, perception of oral health, being of regular treatment facility. Therefore the rate of persons who had experienced the oral disease was significantly higher the younger peoples, worse oral health status and being of the regular treatment source than the other groups. During 1 year period, 64.0% of the cases had treated the perceived oral disease, 36.0% did no action at all during last year. Among respondents, 49.4% had treated their oral disease at dental clinics, 8.0% had treated at community health center or subcenter and remains did not treated at all. The results of logistic regression analysis suggested that statistically significant factors in dental health care utilization were educational level, degree of pain, oral health status and regular treatment facility. Therefore the dental health care utilization rate was higher at groups with the high educational level, serious pain, better oral health status and being of the regular treatment source than other groups. 45.5% of the rural residents did not treat their oral disease immediately due to the no identified need, limitation of time(19.2%), economic limitation(19.2%), and geographical limitation(9.0%). Conclusions: In consideration of above findings, we may conclude that oral health community program to prevent oral diseases should be intensified, oral health education to raise oral health knowledge should be performed periodically.

Purpose : This study was conducted to improve cognitive oral healthcare care by analyzing the correlation between oral health behavior and oral health status Korean adolescents. The subjects were 65,528 youths in 798 schools monitored in the Twelfth Korea Youth Risk Behavior Web-based Survey in 2016. Methods : The general characteristics consisted of 9 items including sex, grade, and academic performance. The academic performance and economic status were restructured into "upper, middle, lower". Subjective health perception and subjective oral health perception were reorganized as "health", "normal", "no health". The sub-areas of oral health behavior include five times of daily brushing during the day yesterday. The number of brushing times was "0", "1-2", "3", "more than 4" After lunch at school, brushing was restructured as "always," "sometimes," "not." The oral health status subscale consisted of 6 items including tooth breakage and toothache at the time of eating. Result : Tooth fracture(43.7 %), pain in mastication(43.7 %), tooth tingling(47.4 %), gum pain and bleeding(45 %), pain in buccal mucosa(43.8 %) and halitosis(46.6 %) were rare in adolescent having healthy oral health status cognitively(P<.001). Nosymptom adolescents without dental sealant showed low tooth fracture(0.64 times), pain in mastication(0.67 times), tooth tingling(0.59 times), gum pain and bleeding(0.84 times), pain in buccal mucosa(0.76 times), and halitosis(0.90 times). Nosymptom adolescents without scaling showed low tooth fracture(0.88 times), pain in mastication(1.03 times), tooth tingling(0.82 times), gum pain and bleeding(0.64 times), pain in buccal mucosa(0.70 times) and halitosis(0.82 times). Conclusion : This study revealed that oral health status is correlated with oral health behavior. Development of educational media and program, and aggressive promotion required to establish oral health Korean adolescent.

Objectives : In order to provide basic data necessary for developing oral health education plane for school continued oral health education by understanding knowledge and activities of oral health. Methods : This study was performed against 324 students at 5th grade of 2 elementary schools in Iksan-si, Jellabuk-do selected through convenience sampling, who were in mixed dentition period that might experience dental caries of permanent tooth. Results : As results, For the knowledge level on oral health by questions, it was found that the case that the elementary school students had correct knowledge on oral health was 'chocolates, snacks, and candies were foods that might often cause dental caries' and 95.8% of the students recognized it well. It was found that for 'must do toothbrushing before going to bed', 'during toothbrushing, I clean my tongue', and 'Proper time necessary for toothbrushing is about 3 minutes', 89.3%, 93.2%, and 89.3% of the students knew the, respectively. When oral health knowledge level by groups was divided into 3 groups and observed, they were classified into Low (0-4 points), Mid (5-7 points), and High (8-10 points). It was found that the knowledge level of each group was High 64.1%, Mid 33.9%, and Low 2.0% and it was identified that the high group took the largest ratio. It was suggested also for oral health knowledge level depending on their father's academic background that there was a statistically significant difference in the group higher than university graduate(p<.05). It was found for oral health knowledge level depending on parents' dental condition that an answer that both parents were good was high and there was a statistically significant difference. But post-analysis resulted that there was no apparent difference among groups. It was found that the ratio of respondents who answered for toothbrushing method 'toothbrush should be moved and rotated downward for the upper teeth and upward for the lower teeth to clean the teeth and gum' were 33.2% of male students and 29.4% of female students and showed statistically significant difference (p<0.05). It was found also that the ratio of respondents who answered to use a toothbrush for about 3 months' were 29.4% of male students and 25.5% of female students and showed statistically significant difference (p<0.05). Conclusions : Oral health program through the elementary school students and their parents for the development of proper oral health care education programs continue to be made should be considered.

The seed of Phaseolus calcaratus Roxburgh (PHCR) is traditionally used for anti-pyretic and antiinflammatory effects. Although these effects are believed to be related to its antioxidant potential, little information is available for the mechanisms by which PHCR seed might scavenge free radicals or otherwise act as an antioxidant. In the present study, we purified some fractions from the ethanol extract of PHCR seed and evaluated each fraction's ability to scavenge free radicals generated by cell-free systems. We also identified active compound that is putatively responsible for free radical scavenging by analyzing NMR spectra. PHCR samples exhibited a concentration-dependent radical scavenging activity against hydroxyl radicals, superoxide anions, and DPPH radicals. Of the samples tested, a methanol-eluted sub-fraction from the PHCR extract, named $FF_4$, scavenged these radicals more effectively than the other fractions. We identified catechin-7-O-$\beta$-Dglucopyranoside as the active compound responsible for free radical scavenging potential of $FF_4$.

Objectives : This study was carried out in order to contribute to preventing dental caries, which is the biggest disease in adolescence and to promoting oral health by implanting a right habit on oral care targeting adolescents, and further to offer basic help to proceeding with making the better health life. Methods : This study carried out questionnaire survey targeting 1,100 students of middle schools where are located in small and medium-sized cities of Gyeongnam from March 7-18, 2011. Statistical processing was performed frequency analysis and cross tabulation, by using SPSSWIN 12.0 program. Results : As for middle school students' oral health education experience, the group with educational experience was indicated to be 52.9% for girl students and 47.1% for boy students(p<.05) in case of gender. Toothbrushing time was indicated to be the highest with 25.6% in 'after having breakfast'. The appearance of toothbrushing after having lunch at school was indicated to be 53.3% for girl students and 26.3% for boy students(p<.001) by gender. The most important reason for toothbrushing accounted for 82.1% in the 1st grade, 71.1% in the 2nd grade, and 67.4% in the 3rd grade depending on school year as for the response as saying of 'aiming to prevent decayed tooth and gum disease.' Thus, the lower school year led to having indicated to be higher in response as saying of brushing teeth for preventing decayed tooth and gum disease(p<.001). As for a toothbrushing method by gender, boy students accounted for 24.2% in response as saying of 'brushing teeth freely', thereby having been indicated to be higher than 15.0% for girl students(p<.001). Conclusions : In order for toothbrushing method to be rightly practiced and habituated continuously, there will be a need of changing adolescents' awareness and of being driven systematically and continuously through oral health education. School oral health education, which can nurture right attitude and habit of oral health care, is thought to be necessarily expanded and executed.

Objectives : OHIP-14 and EQ-5D were used, targeting the residents of farming communities to identify the elements that influence oral cavity's health and quality of life due to health and to identify the importance of oral cavity's health in order to increase health of adults' oral cavity and quality of life via improved health. Methods : This research was conducted from July 17th, 2010 to August 16th, 2010 targeting 600 residents in Goryeong-gun, Gyeongsangbuk-do, aging over 40. The data has been analyzed using Mann-Whitney U test, Kruskal-Wallis test and hierarchical multiple regression through SPSS Win Program 18.0 version. Results : 1. OHIP-14 and EQ-5D based on general characteristics showed lower oral health-related quality of life and health-related quality of life on the following cases: women (p=0.004, p<0.001), older (p<0.001, p<0.001), lower scholastic ability (p<0.001, p<0.001), lower average of average spending money (p<0.001, p<0.001), higher number of chronic disease (p<0.001, p<0.001), less drinking (p=0.012, p=0.008), lower perceived oral health and health status (p<0.001, p<0.001) and non smoking showed only EQ-5D (p<0.001). 2. OHIP-14 and EQ-5D based on oral health behavior showed lower oral health-related quality of life and health-related quality of life on the following cases: no periodic oral check-up (p<0.001, p<0.001), less experience of oral health education (p<0.001, p<0.001), horizontal tooth-brushing method(p<0.001, p<0.001) and lower frequency of tooth-brushing showed only OHIP-14 (p=0.042). OHIP-14 and EQ-5D based on oral health status and subjective oral symptom showed lower oral health-related quality of life and health-related quality of life on following cases: number of existing tooth less than 20 (p<0.001, p<0.001), the number of missing teeth more than 9 (p<0.001, p=0.044), DMFT (Decay, Missing, Filling Teeth) index more than 18 (p<0.001, p<0.001), wears denture (p<0.001, p<0.001), edentulous (p<0.001, p=0.002), have xerostomia (p<0.001, p<0.001) and have chewing discomfort (p<0.001, p<0.001). 3. Factors affecting OHIP-14 were gender, age, perceived oral health status, perceived health status, number of existing teeth, dental status, xerostomia and chewing discomfort, and the of reliability (how well it explains) the final model was 48.7%. EQ-5D showed relevance on gender, age, presence of chronic disease, perceived health status, xerostomia, chewing discomfort and oral health-related quality of life, and the reliability of the final model was 42.9%. Conclusions : In order to improve the quality of life of ruralists, oral health needs to be improved or remained by increasing the rate of possession of the existing teeth and preventing the loss of teeth. In order to do so, improvement of accessibility of dental clinic, change of direction from treatment-centered to prevention-centered health care system, development of oral health education program and various oral health care policies which would vitalize continuous oral health care system are considered to be necessary.

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.

Periodontal disease as one of oral diseases is a chronic disease that continuously worsens once it occurs. It begins with gingivitis in the late school childhood. Its prevalence rate gradually increases in adolescence and continues to rise until young and middle ages. Therefore, the preventive care for the disease in one's whole life is of very importance. Since periodontal disease can be prevented and controlled by oral health behaviors, this study focuses on the relation between adults' oral health behaviors and the disease and emphasizes its importance. Based on the data of the 2015 6th (3rd Year) National Health and Nutrition Examination Survey, the prevalence rate of periodontal disease was compared according to study subjects' oral health behaviors. As a result, gum disease treatment, the count of gum brushing, use of dental floss use of interdental brush, and subjective oral health condition were statistically meaningful. Given that oral health behaviors are related to periodontal disease, it is necessary to conduct a systematic study for developing and performing the oral health education program to make the right habit of oral health behaviors.

This study was conducted to prevent oral disease of primary school, middle school, and high school students, providing basic data for the development of oral health education programs. Data were collected from 898 primary school, middle school, and high school students from March 2, 1999 to May 31, 1999. The results of this study are summarized as follows; 1) The subjects of this study were primary school students(32.6%), middle school students(33.0%), and high school students(34.4%). Boy students were slightly more prevalent than girl students. That is, primary school boys were 56.3%, middle school boys were 53.2%, and high school boys were 52.6%. 2) According to the self-judgement of oral health, primary school students were better than middle/high school students and boy students were better than girl students, 63.5% of primary school students and 57.8% of middle/high school students brushed their teeth once or twice a day. 3) 76.3% of middle/high school students and 63.5% of primary school students experienced dental caries. Girl students were higher than boy students in experiencing dental caries, 35.9% of primary school students and 27.6% of middle/high school students experienced periodontal disease. 4) 22.9% of primary school students and 7.9% of middle/high school students received oral examinations periodically. Girl students showed a higher rate than boy students in primary school, while boy students showed a higher rate than girl students in middle/high school. 5) Explaining to the reasons for reluctant visits to dental hospitals and clinics, 'no time to go' was highest(22.9% of primary school students; 27.4% of middle/high school students) and the rate of 'feeling scared' was second highest. Middle/high school students were more reluctant to visit dental hospitals and clinics than primary school students. In case of problematic symptoms in the mouth, the rate of 'feeling painful or cold in teeth when eating cold or hot foods' was highest, 71.3% of primary school students was concerned about oral health, while 68.6% of middle/high school students was concerned about it. 6) In gathering to the sources of information on oral health, the rate of medical institutions was highest(30.0%) in primary school students, while the rate of family members or persons around them was highest in middle/high school students. 7) 54.9% of primary school students received oral health education, while 13.1% of middle/high school students received it. Only 4.7% of middle school and high school girls received it. In relation to dental health education, the rate of 'possibility of prevention of oral caries or disease of the gum' was highest. 79.5% of primary school students and 80.3% of middle school students answered that they would attend oral health education. 8) 60.4% of primary school students and 60.2% of middle/high school students think the purpose of oral health is to prevent dental caries and disease of the gums. In preventing dental caries, 78.8% of primary school students and 71.8% of middle school students thought that periodical oral examination was effective, 88.4% of primary school students and 88.8% of middle/high school thought that brushing one's teeth was effective and 64.1% of primary school students and 50.7% of middle school students thought that the use of toothpaste containing fluoride was effective. In preventing periodontal disease, 91.1% of primary school students and 90.2% of middle/high school students thought that brushing one's teeth was effective, while 72.4% of primary school students and 70.3% of middle/high school students thought that teeth cleaning was effective. 9) 16.0% of middle school students and 12.7% of high school students thought that their oral health condition was healthy. According to individual experiences in dental treatment, the rate of experience of middle school students was higher than that of high school students, 12.7% of middle school students received oral examinations periodically, while only 3.3% of high school students did so. 10) In cases of 'having no problematic symptoms in the mouth' and 'concerns about oral health', the rate of middle school students was higher than that of high school students. In gathering obtaining information on oral health, the rate of obtaining it through broadcast media including TV, Radio, etc. was highest in middle school students, while the rate of obtaining it through family members or persons around them was highest in high school students. 11) 81.7% of middle school students have not received oral health education. In case of girl students, 97.3% have not received it in high school students. 85.6% of middle school students and 151.2% of high school students think that oral health education is necessary. 12) According to the knowledge level of oral health, the point of high school students($26.33{\pm}2.33$) was similar to the point of high school students($26.23{\pm}2.30$). It appeared that the point of primary school students was highest($26.35{\pm}2.50$) The more concerned about oral health the students were the higher the knowledge level of oral health was. In conclusion, the middle/high school students' knowledge level of oral health was lower than primary school students. The rate of middle/high School students' experience in oral health education was too low. Therefore, it is necessary to intensify oral health education for middle/high school students. Especially, the necessity of oral health education to girl students is strongly recommended. Developing an oral health education program for primary school, middle school, and high school students, related public authority and organizations, teachers; and dentists must actively make efforts together in order to maintain healthy teeth through having students prevent dental caries and periodontal disease.
