Objectives: This study conducted a literature review to systematically confirm the quantitative results of individual studies on oral health-related quality of life (OHRQoL) among elderly adults. Methods: Studies on quality of life related to oral health among Korean elderly adults were selected as targets, and literature published in Korean journals until January 10, 2019, was examined. A total of 179 papers were reviewed using RISS, KISS, eArticle, and DBpia, and 17 papers meeting the final conditions were selected for analysis. Factors were categorized with publication year, sample size, gender, and statistical analysis as main variables. Relevant factors and effect sizes were then encoded, and the values of correlation coefficients and correlation effect sizes were coded. Results: After classifying the factors affecting OHRQoL among elderly adults according to common characteristics, four studies related to food and diet, five studies related to xerostomia, and four studies related to dentures and denture satisfaction were found to be related. Conclusions: Overall, various factors affected OHRQoL among elderly adults. Therefore, oral health among elderly adults must be developed and managed considering the various factors related to OHRQoL.

Objectives: Based on the 7th National Health and Nutrition Examination Survey 1,135 adults aged 19 years were selected as the final study subjects to investigate the relationship between oral health and chewing difficulty in adults. Methods: Frequency analysis, chi-square test, and logistic regression analysis were performed for general characteristics, oral health behaviors, awareness symptoms, and oral health using SPSS Program 21.0. Results: Regarding factors related to chewing difficulty, the oral health was 0.44 times lower than the average level and 0.28 times lower than the good condition. In the case of oral examination, chewing difficulty was 0.85 times lower. The speaking problem was 0.11 times lower in usually than inconvenient and 0.06 times lower in not inconvenient. In the case of un-treatment, it was 0.40 times lower than that in the case of treatment. The chewing difficulty was significantly higher by 2.09 times in the case of experience of tooth pain and 1.36 times in the case of periodontal disease. Conclusions: Based on the above results, it is thought that prevention and treatment are actively needed to identify factors of oral health to improve oral health, to solve chewing difficulty and to improve chewing function.

Oral examination ensures early detection and treatment of oral diseases and improvement of quality of health-related life. This is imperative as it reduces individuals' dental medical expenses and social costs caused by diseases. However, as the low oral examination acceptance rate continues to be a problem, this study was conducted to identify the factors that influence the oral examination of an economically active population. In this study, 4,836 economically active individuals between the ages of 20 and 65 years were studied using data from the 7th National Health and Nutrition Survey in 2018. Logistic regression analysis was performed to determine the factors influencing demographic and sociological characteristics on oral examination after adjusting for complaints of mastication and speech discomfort. As a result of confirming the factors influencing the oral examination, increase in age tended to be inversely proportional to the oral examination. Income level, type of job, and job position were identified as factors that influenced oral examinations. Compared to the group with a high socioeconomic status, which is represented by a group with a high income level or a stable job type or job position, the group with low economic status was found to have a negative effect on oral examination. Oral management of vulnerable groups, who might not be considered while devising oral health management policies, should be promoted through the development and provision of oral health management policies that consider employment status and environment.

Objectives: The purpose of this study is to identify the perceived symptoms of oral and temporomandibular joint disorders in adults and to analyze the factors affecting subjective symptoms of temporomandibular joint disorders. Methods: 249 adults over 20 years old who had subjective symptoms of temporomandibular joint disorders were surveyed and analyzed. Independent t-test and ANOVA test were used to examine the relationship between oral habits and temporomandibular joint disorder according to general characteristics. $Scheff{\acute{e}}$ test was used for post-hoc analysis. Multiple regression analysis was conducted to examine the factors affecting oral habits and temporomandibular joint disorder. Results: First, the factors affecting oral and habitual behaviors were married (p<0.05) and monthly income between 1 million~1.9 million won (p<0.001), higher temporomandibular joint disorder (p<0.01) And the degree of habit was increased. Second, the factors affecting temporomandibular joint disorder were increased in occupation (p<0.05) and the degree of oral habit (p<0.01). Conclusions: In conclusion, it was confirmed that oral habit influences temporomandibular joint disorder. Especially, it is suggested that prevention and promotion of temporomandibular joint disorder are needed to recognize the removal of oral habits.

The purpose of this study was to analyze the relationship between objective oral health status determined by dentists, self-perceived subjective oral health status, and oral health related quality of life (OHRQoL) in the elderly. The related factors affecting OHRQoL in the elderly were also surveyed. Four hundred and thirty elderly individuals who visited the three public health centers and four dental clinics in Busan were selected by convenience sampling. Twelve dental hygienists investigated the subjective oral health status and OHRQoL using the 14-item Oral Health Impact Profile (OHIP-14) and twentyone dentists examined the objective oral health status, including healthy remaining teeth, treated remaining teeth, functional remaining teeth, missing teeth, and non-treated missing teeth. Data were analyzed using SPSS ver. 12.0. OHRQoL was higher when oral and periodontal status was perceived as healthy, when there was no toothache, no interference in mastication, and when study subjects had the ability of food softening. It was also higher when study subjects had ${\geq}20$ remaining teeth and <9 missing teeth, and were wearing denture. The related factors affecting OHRQoL of the elderly were the type of medical insurance, toothache, ability of food softening, perception of periodontal status, and the number of healthy remaining teeth. There was a significant relationship between the subjective-objective oral health status and OHRQoL in the elderly. A continuous oral health care system aimed at retaining ${\geq}20$ healthy remaining teeth is needed to improve oral health and OHRQoL for the elderly, especially for the elderly receiving medical aid.

Objectives : The aim of this study is to investigate the influencing factors of oral health behaviors according to oral health education experiences in middle school students. Methods : The subjects were 301 middle school students who lived in Gimhae and Jinhae. All statistical analyses were performed using SPSS. Results : The group with oral health education experience had higher scores in oral health knowledge(p<.01) than the group without oral health education. The group with oral health education experience has higher scores in oral health behavior (p<.01) than the group without oral health education. The group with oral health education experience has higher scores in self-efficiency (p<.01) than the group without oral health education. The experience of oral health education shows positive correlation with oral health knowledge(r=0.184), oral health behavior(r=0.199) and self-efficiency(r=0.199). There existed a positive correlation between oral health knowledge and self-efficiency(r=0.351). Conclusions : It is necessary to provide oral health promotion program in middle school students. The importance of oral health care is closely related to oral health knowledge.

Objectives: The purpose of the study is to investigate the relations between oral health status and subjective oral health recognition in Korean adolescents. Methods: The survey data were extracted from the 2012 Korea National Oral Health Survey from June to November, 2012. The survey consisted of oral checkup data and the oral health interviewing data of 9,981 adolescents(5,335 male, 4,646 female) by proportional distribution. The questionnaire included general objective oral health status and subjective oral health recognition. The subjective oral health recognition consisted of general characteristics of the subjects, oral health status, oral health behavior, and subjective oral health recognition. Results: According to multiple regression analysis for the relations between general characteristics and subjective oral health recognition, subjective health recognition, the influencing factors were gender, age, the number of tooth brushing per day, intake of snacks and carbonated drinks, regular oral examination, decayed teeth (DT), missing teeth (MT,) and DMFT. Conclusions: The routine oral checkup is the most important method to improve the oral health management in the adolescents. The continuing oral health improvement project must be implemented based on the law and will keep the adolescents in good oral health status.

This study surveyed 57,303 teenagers using the 15th (2019) online Juvenile Health Behavior survey data to understand the relationship between oral health behavior, mental health, and smoking. The results of analyzing the factors affecting smoking experience are as follows: The smoking rate was higher in men (p<0.001), in a lower academic ability (p<0.001), and in moderate economic status was moderate (p<0.001). The smoking rate was higher in 2 or less brushing frequency (p<0.001), in no brushing before going to bed (p<0.001), in no brushing aftger lunch (p<0.001), in no experience of oral health education (p<0.001), and when the subjests felt unhealty in oral health (p<0.001). The smoking rate was significantly higher in those who experienced a lot of stress (p<0.001) and feelings of depression (p<0.001). The odds ratio for smoking was 1.44 when not brushing teeth before bedtime, 0.76 in experience of oral health education, and 1.29 in unhealthy subjective oral health. The odds ratio for smoking was 0.91 in no stress and 1.85 in depression. Since oral behavior and mental health affect smoking, intervening with these factors is necessary to quit smoking.
