This research, with the aim of investigating the selected criteria of dental hospitals & clinic and satisfaction, conducted a questionnaire survey targeting the workers in financial circles; thus, this research drew the conclusion as follows: 1. It was found that people were much affected by those around them in their selected criteria of dental clinic & hospital and acquisition path of dental information, and they preferred the class of a dental clinic with more than 2 directors. 2. As a result of surveying whether the respondents had their favorite dental clinic and if so, why, the cases where the respondents had a favorite dental clinic outnumbered the cases where they didn’t have by 11.8%. To the question about why they had a favorite dental clinic, a lot of respondents answered “Reliability” while to the question asking why not having a favorite dental clinic, a lot of respondents answered “Preference for the nearest location of a dental clinic.” 3. In the survey on the contents of dental treatment & satisfaction, it was found that 40.1% ,among the 59.3% respondents who have recently received dental treatment, went to a dental clinic for dental caries and 25.9% for gum disease. Meanwhile, to the question asking if they would introduce the dental clinic in case they were satisfied with dental treatment, as much as 51.5% respondents said yes, and to the question asking about the reason for dissatisfaction, a lot of respondents answered the lack of skills in dental treatment. 4. As for the selected criteria of dental clinics by gender, 39% of the male respondents said “Because of the recognition as a hospital level” while female respondents said “Through the introduction made by the people around them”, showing a difference between genders(p<0.05). To the question about the selected size, both genders responded they preferred a dental clinic with more than 2 directors, followed by a level of dental hospital In addition, to the question about the reason for selection of a favorite dental clinic, male respondents said the level of dental treatment while females said reliability in a dental clinic is the most important. 5. As a result of comparing the satisfaction with dental treatment by age, the respondents under 49 said they got satisfied with dental caries treatment, followed by gum disease while those over 50 got treatment in the order of gum disease and dental caries. almost 50% respondents in most age groups answered they're satisfied, and in case they answered dissatisfaction with dental treatment, a large proportion of the respondents owed their dissatisfaction to insufficiency in dental treatment skills in their 30s while a high proportion of the respondents in their 40s owed their dissatisfaction to economic burden. 6. As a result of surveying the selected criteria of a dental clinic by district, a lot of respondents from Seoul, Gyeoggi & Incheon district, and Daegu-Busan-Gyeongbuk-Gyeongnam district were found to select their dental clinic through the introduction made by those around them while lots of respondents from Gwangju, Jeonnam, Jeonbuk, Daejeon, Chungnam, and Chungbuk district tended to select their dental clinic by the recognition as a hospital level(p<0.01). To the question about information acquisition path, the respondents from Seoul, Gyeonggi, Incheon, Daegu, Busan, Gyeongbuk, Gyeongnam, Gwangju, Jeonnam, and Jeonbuk district answered the introduction made by those around them, followed by the Internet while the respondents from Daejeon, Chungnam, and Chungbuk district said the introduction made by those around them, followed by TV and radio(p<0.01). 7. As for the selected criteria of a dental clinic consequent upon their final educational background, as high as 40.9% college graduate respondents said the recognition as a level of dental hospital while the percentage of senior high school graduate respondents & those finished with the postgraduate course who answered the introduction of the people around them is as much as 55.6 and 36.9, respectively(p<0.01). As for the preferred size of a dental clinic, the highest 50% of the middle school graduate respondents answered they preferred a level of dental hospital while the highest percentage of the preference for a dental clinic with more than 2 directors was found to be 55.7 in case of college graduates and 60 in case of the respondents finished with the postgraduate course(p<0.05). To the question about whether they’re satisfied after the recent dental treatment, there appeared more or less difference between middle school graduate respondents who said a 100% satisfaction, senior high school graduate respondents 50% satisfaction, college graduate respondents saying 53% satisfaction, and the respondents finished with the postgraduate course saying 42% satisfaction (p<0.01). 8. As for the selected criteria of a dental clinic by monthly income, 45.5 percent of the respondents having an income range of 1 million won, 34.7% of the respondents having an income range of 3 million won and 40.9% of the respondents having an income of more than 4 million won were found to select their dental clinic through the introduction of the people around them; in case of the respondents having an income range of 2 million won, 43% of them said the recognition of a level of dental hospital. To the question about the post-treatment satisfaction, 51.1% of the respondents having an income range of 2 million won said yes; 47.8% of the respondents having an income range of 3 million won said yes, and 54% of the respondents having an income more than 4 million won while 95.7% of the respondents having an income range of 2 million won, 81.8% of the respondents having an income range of 3 million won, and 81.6% of the respondents having an income range of 4 million won responded that they usually introduced the dental clinic once they were satisfied with their treatment(p<0.05). Taken together, it is believed that the size and facilities of medical institutions are important in the selected criteria of dental hospitals & clinics, but what matter more is the introduction made by the people around the person who needs dental treatment. The introduction made by the people surrounding a person needing medical treatment is possible only when the reliability between a patient and medical staff forms; thus, for this purpose, this researcher thinks it’s essential for medical authorities to make efforts not only to give good quality medical treatment and but also to form close ties between a patient and medical staff through the establishment of differentiated medical system.

Dental health education is the process to change students' behavior for their dental health for their life by reasonably managing their own dental health. Furthermore, owing to educating ‘basic dental health knowledge and skill and formulating attitude and ability of dental health management, this education is the most effective way to change educatee, students’ dental health knowledge, attitude, and behavior. The purpose of this study is to change adolescents' promotion of dental health knowledge and their attitude and behavior. Furthermore, this study pursues the formulation of the base to be conducted in higher educational course by expanding current school health service in elementary and junior high educational course. Participants were 118 students taking the class of dental health and life for the second semester of 2009, this class was conducted for two hours a week, 15 weeks in total. Lecture (80%) to deliver basic knowledge regarding the common sense of dental health and relevant practice(20%) were made up of this class. The content of practical education was made up of brushing and the way of using dental floss. The analysis was conducted by SPSS program; the general characteristics was analyzed by frequency, regarding the degree of dental heath knowledge, the comparison for average was conducted; the right answer is 1, the wrong one is 0. Besides, paired-samples t-test was employed to find the change of the degree of dental health awareness before/after education by doing significant test. Results: Regarding the necessity of dental heath education before/after education, in case of “I strongly need”, and “I need”, the 80.5 % of participants supported “before education”, the 92% supported “after education”, so this result supported that dental health education should be needed for adolescents. 1. The result of difference of necessity of dental health education before/after education indicated that the difference of significance has been expressed. 2. Now that the necessity of dental health education has been promoted better after education than before education, dental health education has an effect on the promotion of necessity of dental health education. 3. The dental health education has resulted in the promotion of dental health knowledge and change of attitude. Currently, dental health education has been conducted in elementary, junior high educational course under the school health codes, but that education has not been conducted in higher educational institution, university. 4. This health education should be regularly conducted in university, higher educational institution in order to continue to manage dental health in adults' lives. 5.

The most core project is the administration of a school oral infirmary among the oral hygiene projects at school. This study was to grasp the actual condition of children’s oral health in Jeju region in order to verify an efficiency of an oral infirmary, and suggest the right direction of the administration activity of a school oral infirmary as well as prepare the basic material for the corresponding project to develop continuously, by comparing and analysing the rate of recognition and practice on oral health between a child attending a school with an oral infirmary and a child attending a school without an oral infirmary. The research method was to compare and analyze the actual condition of oral health with regard to elementary schools operating oral infirmaries in Jeju Special Self-Governing Province after requesting the provincial office to release the information. The result of this study is as follows. 1. As a result of comparing the actual dft rate year-on-year, the improvement effect of children's oral health was observed year by year except third grade and fourth grade. 2. As a result of comparing the actual dft index year-on-year, the improvement effect of children's oral health was observed year by year. 3. As a result of comparing the actual DMFT rate year-on-year, the improvement effect of children's oral health was observed year by year. 4. As a result of comparing the actual condition of oral health year-on-year, the improvement effect of children's oral health was observed year by year. 5. As a result of comparing the actual DT rate year-on-year, the improvement effect of children's oral health was observed year by year. 6. As a result of comparing the actual FT rate year-on-year, the improvement effect of children's oral health was observed year by year. 7. With regard to a habit of toothbrushing, a child attending a school with an oral infirmary, has a higher recognition on toothbrushing after meal at school than a child attending a school without an oral infirmary. 8. A child attending a school without an oral infirmary, shows somewhat high extent of practice regarding the management and use of an oral product. 9. A child attending a school with an oral infirmary, indicates high rate of concept establishment regarding special oral terminology. A child attending a school with an oral infirmary, shows much higher recognition by reason that the administration of sealant is performed periodically throughout the year. 10. A child attending a school with an oral infirmary, showed somewhat high necessity of fluoride toothbrushing project at school. This result shows that the development of oral health and awareness of oral hygiene took effect. The awareness of oral hygiene achieved in an oral infirmary will form the basis of oral health care during a lifetime, and lay the foundation of national oral health by reducing dental caries through continuous oral health care. To operate oral hygiene project centering around an advance prevention while avoiding post-treatment, an education in oral hygiene and publicity should be preceded. It will be the most desirable thing if a preventive treatment keeps pace with a proper education according to the individual condition of oral hygiene, as school oral infirmaries are established extensively and task forces for oral hygiene are settled. And a continuous education in oral hygiene should be carried out, and the relevant organizations need to expand it through the development of oral hygiene education material.

The purpose of this study was to examine the effect of oral health education provided by dental hygiene sophomores on the oral health care skills of elementary school students by conducting the PHP index test in a bid to suggest some of the right directions for sustained oral health education. The subjects in this study were elementary schoolers who were in their third and fourth grade. The selected sophomores who majored in dental hygiene at a college located in Seoul provided oral health education to the elementary school students twice from October 11 to November 9, 2010, at the interval of two weeks. The findings of the study were as follows: 1. As for the oral health status of the elementary schoolers, the rate of those who had dental caries stood at 28.7 percent. The rates of the third and fourth graders who had dental caries respectively stood at 52.9 and 47.1 percent(χ2=2.88, p<.090). Malocclusion was found in 10.4 percent among which the third and fourth graders respectively numbered 42.9 and 57.1 percent(χ2= .59, p<.441). The diseases that indicated the presence or absence of the residual root of baby teeth were found in 0.5 percent who included the fourth graders only(χ2=2.72, p<.99). 26.9 percent needed pit & fissure sealing, and the rates of the third and fourth graders who needed that respectively stood at 61.3 and 38.7 percent(χ2=17.27, p<.000). Periodontal diseases were found in 2.0 percent out of which the third and fourth graders respectively numbered 91.7 and 8.3 percent(χ2=9.60, p<.002). There were significant gaps in the necessity of pit & fissure sealing and the presence or absence of periodontal diseases according to their grade. 2. The elementary schoolers took the PHP index test while they received the oral health education. They got a mean of 2.10 before that education was conducted, and they showed a rise of 0.16 by getting 2.26 after the first oral health education was provided. But after the second oral health education was offered, they got 1.44, which was a drop of 0.82. 3. Concerning the relationship between the oral health education and changes in the PHP index by grade, the third graders got 2.62 before they received that education, and the fourth graders got 1.60. Thus, the fourth graders scored less than the third ones. After the first oral health education was provided, however, the fourth graders got 2.11, which was a rise of 0.51, though the third graders got 2.42, which was a drop of 0.2. After the second oral health education was conducted, the third graders got 1.77, which was a drop of 0.65, and the fourth graders got 1.12, which was a drop of 0.99.

The purpose of this study was to examine the raw data of the secondary 2008 national health and nutrition survey of the fourth term in an attempt to find out the impact of health risk factors significantly linked to obesity on peridontal diseases. The subjects in this study were 2,321 healthy obese adults aged between 20 and 64. Those who had hypertension, diabetes, hypercholesterolemia, hypetriglyceridemia, myocardial infarction or angina pectoris that might trigger peridontal diseases or get them to keep their health-related behavior in control were ruled out, and those who took medicine due to one or more of these diseases were excluded as well. The relationship among peridontal diseases, obesity and health risk factors was checked in each of the obese group(BMI≥ 25 ㎏/m2, M=1,798) and the normal BMI group(BMI＜25kg/m2, M=508), and the relationship of the three was investigated in each of the group with normal periodontal condition(CPI＜3, N=.1683) and the group with periodontal diseases(CPI≥3, N-590) at the same time. The major findings of the study were as follows: 1. BMI had a statistically significant relationship to peridontal condition. The obeser adults tended to be 1.304-fold more afflicted with periodontal diseases. 2. There were significant relationship between BMI and smoking and between peridontal condition and smoking. Those who smoked tended to be 1.540-fold more afflicted with peridontal diseases. 3. When their habits related to oral health were analyzed such as a daily mean toothbrushing frequency and the use of oral hygiene supplies, significant intergroup gaps were found according to BMI and periodontal condition. There was a tendency that those who made more use of oral hygiene supplies were 0.739-fold less afflicted with peridontal diseases. 4. When they took a blood test to check their total cholesterol, HDL-cholesterol, triglycerides, fasting glucose and white blood cell counts, significant intergroup gaps were found according to BMI and peridontal condition.
