Purpose: The purpose of this study is to analyze the factors affecting the longevity of failed prosthesis and the success rate of the prosthesis based on the data evaluated with the newly developed Korean Academy of Prosthodontics (KAP) criteria. Materials and methods: Evaluation was performed in the restored prosthesis for patients who visited the prosthodontics department of the 13 dental university hospitals and general hospitals. The status of the prosthesis was classified into four categories: Good, Fair, Bad, Worst. The success was recorded if only the category was classified in 'good'. The mean duration of failed prostheses and the success rate through Kaplan-Meier method were analyzed. Results: A total of 1,804 cases of prosthesis were evaluated: 810 cases of fixed dental prostheses (FDP), 519 cases of Removable Dental Prostheses (RDP), and 475 cases of implant prosthesis. The mean duration of failed FDP was $11.41{\pm}0.30years$ and the median was 10 years. The mean duration of failed RDP was $8.18{\pm}0.29years$ and the median was 7 years. The mean duration of failed implant prosthesis was $7.99{\pm}0.30years$ and the median was 7 years. The factors related to the failure were as follows: number of units, abutments, abutments treated with root canal, and plaque index in FDPs; treated and opposing dentition in RDPs; the number of implants, duration of use, and plaque index in implant prostheses. Conclusion: The average duration of failed prosthesis was 11.41 years for FDPs, 8.18 years for RDPs, and 7.99 years for implant prosthesis, according to the evaluation with newly developed KAP criteria.

To prepare a method for improving the oral health-related quality of life for Chinese foreign students by examining the oral health care behavior affecting the oral health-related quality of life, a self-administered survey was conducted with 236 Chinese foreign students at an university located in Jeonbuk during April 2 -May 5, 2013. The results showed that 65.3% had not visited the dentist within one year, 82.6% had not received scaling within one year, and 68.2% had not received oral health education. In regards to the OHIP-14 according to the general characteristics, there was a significant difference in the school year, health insurance enrollment status and overseas study life satisfaction (p<0.05). In regards to the OHIP-14 according to the oral health care behavior, there was a significant difference in the subjective oral health condition, the experience of having visited a dentist within one year and an experience of having received scaling (p<0.05). As for the influencing factors on the oral health-related quality of life, they were found to be the subjective oral health condition and the experience of having received scaling within one year (p<0.05). For the purpose of helping Chinese foreign students to conveniently use medical institutions when oral health-related problems arise, there is a need for a translated version of the guidebook in their native language, the availability of medical professional interpreters, the availability of a university level oral health service center, and practical oral health education to enhance oral health.

The purpose of this study was to provide information on the development of an oral-health promotion program geared toward office workers. The subjects in this study were 240 employees at the headquarters of S construction company. After a survey was conducted in July and August 2008, the answer sheets from 208 respondents were gathered, and 191 answer sheets were analyzed except 17 unanalyzable ones. The findings of the study were as follows: 1. In regard to subjective oral health status, the largest number of the participants that accounted for 37.2% found their mouth to be neither healthy nor unhealthy. The greatest number of them that represented 58.1% had never visited a dentist's office to receive preventive treatment. 2. Regarding relationship between toothbrushing education experience and toothbrushing frequency, the most common toothbrushing frequency was three times a day( 46.5%) among the company employees who had ever received that education. In the event of the office workers without that experience, the most prevalent frequency was three times(63.6%). The toothbrushing frequency was statistically significantly different according to the toothbrushing education experience(p<0.05). As to the relationship of toothbrushing education experience to tooth- brushing method, the largest number(48.2%) of those who had ever received that education brushed their upper and lower teeth along with the gums by rotating the toothbrush downward from the top and upward from the bottom respectively. In the event of the office workers without that experience, 49.4 percent brushed their teeth and gums by rotating the toothbrush up and down. Thus, whether they had ever received education about toothbrushing made a statistically significant difference to their toothbrushing method(p<0.05). 3. As a result of evaluating their oral health belief by utilizing a five-point scale, they got a mean of 2.95. In each area of oral health belief, they got the best marks in benefit(3.66), salience(3.42), barrier(2.84), susceptility(2.58) and seriousness(2.23). Given the above-mentioned finding of the study, two sorts of oral health beliefs, which are benefit and salience, should be stressed in the development of oral health education programs that cater to company employees. And sustained research efforts should be channeled into finding out the relationship between oral health and actual oral health care.

The purpose of this study is to investigate the effects of awareness of oral health on oral health status and oral health behavior with subjects of students in the middle school which is the important period when lifetime set of teeth is completed with eruption of the second molar tooth and complete set of permanent teeth, and provide the basic data for development of oral health program for adolescents. We examined oral condition and conducted the survey about students' awareness of oral health and behavior in the middle school located in JeonJu. As the results of oral examination, dental caries and malocclusion were higher in female students and periodontal disease was higher in male students (p < 0.038). There was no significant difference in awareness of oral health between male and female students. However, M = 4.08 out of 5 point scale, which was high. For oral health behaviors, female students (M = 4.508) was higher than male students (M = 4.257) in the question of 'I visit the dental office when my gums are bleeding'. Female students (M = 4.547) was higher than male students (M = 4.333) in the question of 'I use the dental floss after brushing my teeth'(p<0.05). Awareness of oral health gave the significant effect on the oral health behavior at 95 % confidence level. Therefore, the education for oral health behavior is required to improve oral health and studies are needed to present the development of program for awareness and knowledge of oral health affecting behavior.

Objectives: The purpose of the study is to investigate the relationship between bone mineral density and remaining teeth in Korean adults. Methods: Using National Health and Nutrition Examination Survey(KNHANES) 5th Year 1(2010), 1,985 adults over 50 years old having bone mineral density test were selected. Male adults were 883, and female adults were 1,102. The raw data consisted of general characteristics of the subjects, bone density data, and oral examination data. The questionnaire consisted of general health survey, laboratory examination study, and nutrition study. Data were analyzed using SPSS 18.0 program for multiple regression analysis, ANOVA, t-test. The variables included general characteristics of the subjects, health behavior, diet habit, and oral health behavior. General characteristics consisted of gender, age, residence area, education level, marital status, monthly income, and vocation. Health behavior consisted of smoking, alcohol drinking, body mass index(BMI), physical activity, and mental health. Diet habit consisted of frequency of meal, milk, coffee, and calcium ingestion. Oral health behavior consisted of frequency of tooth brushing, use of oral health care devices, and oral examination. Systemic diseases were measured by the questionnaire for hypertension, diabetes mellitus, and hyperlipidemia. Bone density was measured in T-score of femoral bone, neck of femur, and lumbar vertebrae. Bone density was classified into normal($T-score{\geq}-1.0$), osteopenia(-2.5 < T-score < -1.0), and osteoporosis ($T-score{\leq}-2.5$). The remaining teeth were measured by the differences between normal teeth and missing teeth. Results: Smoking and age are the most influencing factors on the number of remaining teeth and bone density(p<0.01)(p<0.05). Those who had higher bone density, younger age, and nonsmoker significantly had more remaining teeth. Those who were men, diabetic, lowly educated women, and low birth weighted persons tended to have less number of teeth(p<0.01). Conclusions: The study suggested that there were significant differences between men and women according to the oral health management behavior and systemic disease control. Proper management of the oral health and good quality of bone mineral density can reserve the remaining teeth through the whole life.

The purpose of this research is to plan the activation of university health business through the appraisal of the function and role of university health centers. To be more specific: Firstly, analyze the facility, personnel, health service of the health centers, Secondly, appraise the role and function of the health centers, and Thirdly, consider the activation plans of health centers. The research method taken was the study of surveys conducted and written research materials on 5 women's universities in Seoul. These materials where descriptively analyzed by converting the surveys, facility and usage of health center and current personnel status in to percentage. The major results of the research are as follows: Unlike as stated in each university's additional clause on the number of personnel were working. This lack of specialized personnel resulted into lack of specialized and various services. Medicine for external application were stocked well whereas only simple medicine for internal application were on shelf and were issued only with a doctor's prescription. Universities with a full-time doctor had various available equipments. One university conducting dental treatment was equipped with indirect chest camera, dental X-ray, unit, chair(dental treatment chair) and even supersonic, electrocardiogram were available. In the case of D women's university, the number of beds compared to the number of students was lower than that of the other 3 universities, to the total size of the university was smaller than that of the other 3 universities. Among health prevention and care matters, health consultation was the only matter practised by all universities. Uniquely, there was one university that hosted epidemic prevention business. There are various tests given by each university, with each showing many differences, but some universities did not even conduct these tests. Vaccinations were usually being conducted through commission. All universities provided basic treatment, therefore matters concerning treatment at health centers were being conducted well. Concerning the management of equipment and documents, all the matters were being conducted except one university where instead of a student medical record, they were using a daily record. Because these were women's universities, most of the educations were on women's health. The subjects of these educations included: sex, contraception, prevention and control of tuberculosis, obesity, mouth hygiene, alcohol, geriatric disease, mental health and first-aid. The rate of health center usage is growing. Being women's universities, the service and treatment practised were mostly concerning sex education.

The study performed questionnaire to the patients receiving implant operation, who visited dental clinics and hospitals(2 hospitals and 5 clinics) from Jul. 1, 2009 to Sep. 12, 2009 in order to study the factors giving effects to patient's satisfaction in the selection of implant. 145 questionnaire papers collected from patients were analyzed with SPSS12.0 program. The result revealed that the satisfaction with implant operation was usually normal when implant was operated because of tooth extraction due to dental caries and periodontal disease and it was usually high when implant was operated because of wound(P<0.05). When considering each cause of tooth extraction, the satisfaction with pronunciation function was usually normal(P<0.001), the satisfaction with functional part including foreign body sense was very low when the cause of operation was periodontal disease(P<0.01). The satisfaction with hospital environment depending on the cause of hospital selection was usually high when hospital was selected because of doctor's fame. It was low when hospital was selected because it was close to home(P<0.001). The satisfaction with the number of hospital visits depending on the number of implanted teeth was usually low when many teeth were implanted(P<0.01). The analysis on the satisfaction with tooth shape and color showed that the satisfaction was high when '1~2' teeth and 'more than 6' teeth were implanted(P<0.05). In order to improve patient's satisfaction with implant, it is necessary to recognize individual's oral status and request correctly. It is determined that proposal of operation period, number of hospital visits, function and expected aesthetic satisfaction degree will contribute to the improvement of mutual reliance between doctor and patient and post-operation satisfaction degree.

The purpose of this study was to examine the impact of stress on the habits of temporomandibular disorder in college students. The subjects in this study were 396 male and female students who were in their first to fourth years at five different colleges located in Jeollabuk-do. The findings of the study were as follows: As for the degree of bad oral habits, "sleeping on one side" was the most common bad oral habit, followed by "enjoying caffeinated beverages," "resting the chin on the hand or a thing" and "chewing food in one side of the mouth only." As a result of analyzing their stress by general characteristics including gender, there were significant differences according to gender in stress about school life problems, one's own problems and economic difficulties, and only stress about one's own problems statistically significantly varied with academic year. When the correlation of the factors was analyzed, perceived stress about school life problems and one's own problems had a significant positive correlation with bad oral habit scores. When a multiple linear regression analysis was made to determine the influence of general characteristics and perceived stress on bad oral habit scores, gender, academic year, self-rated oral health status, stress about school life problems and stress about one's own problems were identified as significant variables. The findings of the study illustrated that there was an organic relationship between the bad oral habits and stress of the college students.
