This study is a 1:1 survey of 154 elderly 65 or older to find out the direct and indirect effects of oral dryness on their quality of life through the medium of depression. As a result, the subjective oral health of the elderly and oral dryness, depression and quality of life were correlated. In the medial effect of subjective oral health and oral dryness on the quality of life, subjective oral health is the quality of life(β=.23, p<.01), depression(β=-.24, p<.01)and the influence of subjective oral health when depression is controlled(β=.08, p>05) was not significant and was completely mediated. Oral dryness is the quality of life(β=-.24, p<.01) and depression(β=.37, p<.001) was shown to have a significant effect and the influence of oral dryness when depression is controlled(β=.00, p>.05) was not significant and was completely mediated. In order to improve the quality of life for the elderly, it is necessary to develop and apply a comprehensive arbitration program that can improve oral health and oral function, and to study the effects of consequences in the future.

This study conducted a survey from September 5 to 30, 2020 targeting 415 workers participating in regional self-sufficiency center programs in four locations in Daejeon and Daegu. The purpose of the study was to examine oral symptoms of the study subjects and the effects if psychological anxiety parameters on oral health and quality of life. As a result of the study, oral dryness, temporomandibular joint symptoms, and periodontitis all had a significant effect on oral health and quality of life, and psychological anxiety factors had a partial mediating effect. The subjective oral symptom problems led to a negative psychological state, which could further impair the quality of life. In the future, the results of this study can be used as basic data for expanding psychological counseling programs for self-supporting workers and improving oral health policies for regular oral health education.

This study performed an investigation to determine the impact of the oral health status and oral health behavior of pregnant women on quality of life and analyzed the results. The data was tested using the Shapiro-Wilk normality test for the key measuring parameters by using PASW Statistics 18.0. There were significant differences in subjective oral health status and oral health interest had significant differences depending on the period of in pregnancy. 46.5% of surveyed subjects considered themselves as 'healthy', and 51.2% considered their oral health status was 'healthy' while 57.5 responded they were interested in the oral health. As for the quality of life according to the oral health behaviors, when the subjects did not have any experience of receiving oral health education, when the tooth brushings were ${\leq}3$ times, when they had not received examination on a regular basis, and when they had no experience of scaling, the quality of life was very low. Significant impact variables on the OHIP-14 include longer pregnancy term, no experience of childbirth, subjective health status and poorer subjective oral health status, and the low health-related quality of life. In this study, it was considered as necessary to develop improved oral health education programs because the oral health-related quality of life was closely associated with oral health and oral health behaviors perceived subjectively.

The purpose of this study was to provide basic data on counseling, education, and treatment related to orthodontic practices through an understanding of the relationships between orthodontic treatment, oral health-related quality of life, and happiness of high school students. The subjects in this study were 500 students in Grades 1~3 of a high school in Jeollabuk-do. We conducted a survey targeting this group; the results revealed the following: in the social support item, peer support showed significant differences in the matter of orthodontic treatment (p<0.05). In oral health-related quality of life, the students without orthodontic treatment showed 14.09 scores that were higher than the students with treatment (p<0.05). Regarding happiness, the students with orthodontic treatment showed higher scores which were significantly different from the those of the non-orthodontic treatment group (p<0.05). Additionally, upon examining the correlations between self-esteem, social support, oral health-related quality of life, and happiness, oral health-related quality of life, peer support, and happiness showed the negative (-) correlations while the rest of the variables showed the positive correlations (p<0.05). The factors having effects on oral health-related quality of life included the stress, matter of orthodontic treatment, and teachers support (p<0.05). The factors having effects on happiness included self-esteem, peer support, and family support (p<0.05). Based on the above results, even though dental orthodontic treatment had negative effects on oral health-related quality of life, it had positive effects on happiness. Consequently, it would seem necessary to seek active methods to increase oral health-related quality of life. This improvement could be achieved by minimizing inconveniences, such as mastication, in the process of dental orthodontic treatment, and developing programs that could enhance happiness.

The purpose of this study is to provide basic data for confirming the convergence relationship between flexibility exercise on quality of life, oral condition, and oral health-related behavior. Data from the 2012 KNHNES were used, and complex sample linear regression analysis and logistic regression analysis were performed to confirm the effects of flexibility exercise on quality of life and oral health. As a result, those who controlled for demographic characteristics and did not exercise flexibility had .027 times worse exercise ability among the subcategories of quality of life, and .152 times higher number of carious permanent teeth. Among the symptoms of temporomandibular joint disorder, pain symptoms were 1.633 times higher in those who exercised flexibility (p<.05). Therefore, it is considered that flexibility exercise has value in that it has suggested a relationship not only with general health but also with oral health.

Background: This study aims to investigate the effect of restrictions on oral health-related activities of young adults, middle-aged, and elderly in Korea on the quality of life and contribute to the development of intervention strategies to improve the quality of life by improving the importance of oral health care and healthy lifestyle habits of adults. Methods: The 8th National Health and Nutrition Survey was used, targeting adults categorized into three age groups: young adults aged 19 to 29, middle-aged adults aged 30 to 49, and prime-aged adults aged 50 to 64. Demographic characteristics and EQ-5D, HINT-8 and oral-related toothache experience, chewing problems, speaking problems, and complaint of discomfort to chew analyzed. T-test and one-way ANOVA were performed to find out the difference in quality of life according to the restrictions on oral activities of adults, and linear regression analysis was performed to investigate the factors affecting the quality of life of adults. Results: The differences between EQ-5D and HINT-8 according to the restrictions on oral health-related activities of young, middle-aged, and prime-aged were statistically significant in all oral activity restriction variables(p ≦0.05). Factors affecting EQ-5D of all adults were statistically significant in all variables such as region, gender, household monthly income, education level, basic living status, economic activity, subjective oral health status, toothache experience, chewing problem, speaking problem, and complaint of discomfort to chew(p ≦0.05). Factors affecting HINT-8 of all adults were statistically significant in variables such as gender, household monthly income, education level, basic living status, economic activity, toothache experience, chewing, speaking, and complaint of discomfort to chew(p ≦0.05). Conclusions: Various measures are needed to improve the quality of life in old age by allowing adults to face physically, mentally, and socially prepared old age. Based on the results of this study, an adult oral health program should be developed to improve the oral health and quality of life of adults.

The purpose of this study was to compare the oralmyofunctions (occlusal force, tongue pressure, lip force) of adults and elderly people. And analyzed the factors affecting oral health related quality of life and dysphagia. The study was conducted on 73(over 20 years of age) Residing in Daejeon and Nonsan From December 2017 to May 2018. The data was analyzed using one-way ANOVA, pearson's correlation and multiple regression. The masticatory strength of each age group evaluated the right and left posterior occlusal forces. the elderys group (8.93, 10.80) were lower than adults group(12.51, 14.61) and middle age group(11.63, 14.75)(p>0.05). The tongue pressure was statistically significant lower in eldery group(37.43) than the adult group(60.55), middle-aged group(50.61) (p=0.000). In addition lip force was significantly lower in eldery group(8.57) than adult(12.01), middle-aged(11.37)(p= 0.000). The tongue pressure was positively correlated with the number of natural teeth(r=.566, p<.05), and the lip force (r=.497, p<.05). The quality of life quality related to oral health and dysphagia was tongue strength(p<0.05). It is necessary to recognize the risk of declining oral muscle function caused by aging. especially tongue strength is associated with quality of life and dysphagia. In order to improve the quality of life related to oral health in the aged society, the necessity of regular oral administration and oral muscle training was proposed.
