Purpose: This study aimed to obtain basic data on oral health improvement by investigating the EQ-5D index according to the oral prosthesis status of elderly persons aged 65 years or older in Korea using the Seventh Korea National Health and Nutrition Examination Survey. Methods: In this study, 3,426 elderly persons aged 65 years or older were included to analyze the relationship between the dental prostheses status and EQ-5D index in the collected data. Results: Compared to the "complete denture" in oral prosthesis, EQ in case of no dental prostheses or fixed dental prostheses is comparable to removable prosthetics such as "no dental prostheses," "one fixed bridge," and "two or more fixed bridges." Removable partial denture and complete denture required for the maxillary and mandibular EQ-5D index were significantly higher in "not necessary" than in "complete denture necessary" in all the elderly persons. Conclusion: The condition of the dental prosthesis and the need for a removable partial denture and complete denture for the elderly's EQ-5D index were confirmed, and it was found that the fixed dental prostheses were more effective than the removable dental prostheses. Therefore, oral health education programs for the elderly should be developed to promote dental function and oral health maintenance.

Objectives : The objective of this study was to investigate the relationship between the status and necessity of dental prosthesis and mastication function in the Korean elderly. Methods : This study investigated 4,557 elderly people aged over 65 in the 5th Korea National Health and Nutrition Examination Survey(2010-2012). Frequency analysis, ${\chi}^2$ test, and logistic regression analysis were used. Results : Those aged over 75 complained of greater discomfort in mastication function than those from 65 to 74, and it was statistically significant(p<0.001). Mastication discomfort was not so significant in those with higher education and higher income(p<0.001). Those who did not use prosthesis tended to have better mastication function(p<0.001). Denture users complained of mastication discomfort when they used it(p<0.001). Conclusions : This study verified the relationship between the discomfort in mastication and related factors, and will provide the basic data for the access to dental clinic services.

Purpose: The purpose of this study is to provide basic data for the improvement of dental care service for patient care. Methods: The survey period was from December 10, 2018 to June 10, 2019. The subjects were 180 patients who were treated with dental implant in 20 dental hospitals and clinics in Daejeon and Gyeonggi province. A total of 145 questionnaires were analyzed except for 35 copies which were unreliable or difficult to analyze. Results: The most important care method for prolonging the life time of dental implant prosthesis was the highest rate of correct brushing (39.4%), and a majority in the subjects used oral hygiene products (91.0%). With regard to discomfort after dental implant prosthesis, food particles between the teeth showed the highest response (49.7%), and discomfort with gum infections and bleeding and reduced mastication increased significantly with age (p<0.05), whereas feeling of irritation decreased significantly with age (p<0.05). Conclusion: This study is meaningful in that it approached the perception and discomfort of prosthesis from the patients' point of view. It needs to establish the basic data to improve dental treatment service for patient care.

STATEMENT OF PROBLEM: Factors affecting patients' decision-making for dental prosthetic treatment should be examined in terms of understanding improving patients' oral health. PURPOSE: The main purpose of this dissertation was to investigate patients' dental prosthetic treatment and factors affecting patients' decision-making for dental prosthesis treatment in Deagu and Gyungbook areas. MATERIAL AND METHODS: This study was based on the preliminary survey of dental patients conducted from July 1 to August 31 in 2006. A total of 700 questionnaires had been distributed and 640 were collected. 629 questionnaires were used for the statistical analysis. Descriptive and inferential statistics, such as frequencies, cross tabulation analysis, correlation analysis, logistic regression analysis, and multiple regression analysis were introduced. In the multiple regression analysis and logistic regression analysis, twenty-two independent variables were employed to explore the factors which have impacts on decision-making and satisfaction. RESULTS: The results of this dissertation are as follows: Logistic regression analysis turned out that monthly income, age, degree of expectation, marital status, and employer-insured policy of national insurance statistically increased the odds of decision-making of dental prosthesis treatment. But educational attainment decreased the odds ratio of the decision-making of dental prosthesis treatment. However, the rest independent variables do not have statistically significant impacts on the decision-making of dental prosthesis treatment CONCLUSION: Among independent variables, marital status had the most significant influence on the decision making of dental prosthesis treatment. Finally, suggestions for the future study and policy implications to improve satisfaction of the patients' dental prosthetic treatment were discussed.

The purpose of this study was to investigate the quality of life of clients who treated and equipped prosthesis in Eulji University Hospital in Dae-Jun City. The results of this study were as follows. The oral status of Female had more carious tooth than male had. Carious tooth(p<0.05) and losed tooth(p<0.001) was more popular in older female. The frequency of treated tooth was higher under 59 years old female than over 60 years old(p<0.01). In education category, carious tooth(p<0.05) and losed tooth(p<0.000) was more popular in low education than high education In the score of relation of OHIP-14 category and general characteristic, female was significantly higher than male in dysfunction( p<0.05), physical disorder(p<0.001) and activity disorder(p<0.05). The score was significantly higher in older than younger in dysfunction(p<0.05), physical disorder(p<0.001) and activity disorder(p<0.001). The score of education was significantly higher in low education group than high education group in physical pain (p<0.001), mental discomfort (p<0.001). The score of marriage status was significantly higher in marriaged group than other group in dysfunction (p<0.05) and mental discomfort (p<0.05). In the score of relation of OHIP-14 category and oral status, the score of carious tooth group was significantly higher in dysfunction(p<0.05), physical disorder(p<0.05) and activity disorder(p<0.05). The score of losed tooth group was significantly higher in dysfunction(p<0.05), physical pain (p<0.05), mental discomfort(p<0.05), physical disorder(p<0.05) and activity disorder(p<0.01). The score of non treated tooth group was significantly higher in dysfunction(p<0.05), mental discomfort(p<0.05), social disorder(p<0.05) and activity disorder(p<0.05). In the score of relation of OHIP-14 category and the sort of prosthesis, the score of being bridge group was significantly higher than being crown group in activity disorder(p<0.05). The OHIP-14 category and the number of prosthesis was not significant relationship. These results suggest that the information and services of the process of dental prosthesis based on subjective evaluation should be provided to clients rather than based on clinical evaluation. The continued system of oral management should be developed and provided.
