Purpose: This study utilizes big data from the 8th (2021) National Health and Nutrition Examination Survey to determine first, the relationship between chewing discomfort in the elderly and some systemic diseases and second, whether oral diseases and oral health problems are related to systemic diseases. Since this may have an impact, we aim to provide basic data to facilitate the expansion and emphasize the importance of integrated health management education. Methods: Original data from the 8th (2021) National Health and Nutrition Survey, conducted by the Korea Centers for Disease Control and Prevention, were analyzed using SPSS Version 21.0 (IBM). A complex sample frequency analysis was conducted to confirm the general and health-related characteristics of the study subjects, and a complex sample cross-analysis was conducted to determine chewing discomfort according to both general and health-related characteristics. Complex sample multiple logistic regression analysis was conducted to determine the effect on chewing discomfort. Results: In order to analyze the factors that affect chewing discomfort, the general characteristics that showed significant differences in chewing discomfort were adjusted for age, personal income, education level, basic livelihood security, high blood pressure, subjective health status, and subjective oral health. It was found that the condition had a statistically significant effect on chewing discomfort. Conclusion: The findings of this study demonstrate that high blood pressure, subjective health status, and subjective oral health status affect chewing discomfort; hence, measures such as developing and operating programs to improve national oral health are needed. We hope that our study will be used as basic data for research into chewing discomfort and systemic diseases in the elderly.

The purpose of this study was to investigate the perception of calculus removal, an essential factor in periodontal disease in the elderly population. Further, the study aimed to identify the oral hygiene management matters of individuals and to use the information as primary data for preventing dental loss and improving the prevention of chronic diseases. From December 20, 2019, to January 15, 2020, the results of 171 studies on oral hygiene management and awareness of calculus removal among the elderly aged 65 or older in Busan and Gyeongnam are as follows: The elderly with good health appreciated their functional oral health status and showed significant differences (Χ²=298.26, p<.001). Many of the elderly brushing their teeth at least three times a day had a better health status and showed significant differences according to their health status (= 134.42, p <.001). Usually, older people who are in good health have a dental floss (Χ²=89.31, p<.001), and the dental floss were used more often and significantly differed depending o health status (Χ²=92.53, p<.001). The elderly's perception of tartar removal has shown that the overall average out of five points is positive at 3.48. Older female adults were more positive and showed significant differences regarding gender (t=-7.95, p<.001). Senior citizens aged 65 to 70 were more positive about dental removal than those aged 71 or older, with significant differences in age (t=6.65, p<.001). As described above, oral hygiene management for the elderly population needs to develop a periodontal disease prevention program linked to systemic diseases, considering that there are many chronic diseases.

Objectives: The purpose of this study was to examine the effects of oral and mental health status on temporomandibular joint disorders (TMDs) and the effects of TMD symptoms on quality of life using data from the 5th 2012 National Health and Nutrition Examination Survey. Methods: A total of 1,154 people were selected as subjects for the study. Temporomandibular joint (TMJ) sounds (672 persons), TMJ pain (227 persons), and TMJ dislocation (255 persons) were the factors studied. The complex sample chi-square test was performed to compare demographic characteristics according to the three groups of TMD symptoms. Complex sample logistic regression analysis was performed to confirm the effect of oral and mental health status on TMDs, and complex sample linear regression analysis was performed to check the effect of TMDs on the quality of life (EQ-5D). Results: After adjusting for demographic characteristics, those without TMJ sound symptoms had lower pain/discomfort (OR: 0.055, CI: -0.095 to -0.016) and anxiety/depression (OR: 0.053, CI: -0.092 to -0.014). Those without TMJ pain had lower pain/discomfort (OR: 0.119, CI: -0.192 to -0.046) and anxiety/depression (OR: 0.071, CI: -0.137 to -0.004). Pain/discomfort (OR: 0.063, CI: -0.125 to -0.001) was lower in those without TMJ dislocation symptoms. After adjusting for mental health status, pain/discomfort (OR: 0.088, CI: -0.161 to -0.014) was found to be lower in those without TMJ pain symptoms (p<0.05). Conclusions: Based on the results of this study, the treatment of TMDs, oral health, and also mental health, is needed to improve the quality of life.

Background: Dementia is a condition in which a person who has been living a normal life suffers from various cognitive impairments in memory, words, and judgment that considerably disrupt daily life. The oral care ability and subjective oral status of elderly individuals with dementia are lower than those of a healthy person. The oral health care of individuals admitted to nursing homes inevitably falls to nursing assistants and nursing care staff. This study aimed to investigate the need for oral health management items of and to provide basic direction for the future of the Dementia National Responsibility System. Methods: Elders aged 65 years and over were selected from a comprehensive welfare center. A total of 155 questionnaires were analyzed. The questionnaire consisted of 15 items about general status, 9 items about recognition of the Dementia National Responsibility System, 5 items of the subjective recognition of oral health, and 6 items of the correlation between oral health and dementia. Results: Among our subjects, 71.0% answered that they did not know about the Dementia National Responsibility System, 78.7% answered that they think they need the system, and 81.9% think that they should add dental health items to the Dementia National Responsibility System. The response to the need for dementia national responsibility, oral health items in the Dementia National Responsibility System, and oral specialists all showed scores of >4 points. The need for the Dementia National Responsibility System, oral health items, and specialists were found. Conclusion: It is necessary to include oral health care items in the Dementia National Responsibility System so that elderly individuals with dementia can receive the needed oral health care.

The purpose of this study was to investigate the effects of stress on oral health and health behaviors. The study was conducted on 72,060 people using 11th Youth Health Behavior Online Survey in 2015. The study shows that In general, female students, high school students and students with high performance ranking are more stressful than male students, middle school students and students with low performance ranking respectively. Studies have shown that students who do not exercise a lot and have not breakfast get relatively high stress. Plus, the stress index was also high and statistically significant. (p<0.001). The study also shows that students who have got symptoms of "tooth pain when eating" and "bleeding gun" at the questionnaire of "Self-assessed Oral health status"get high stress relatively. And the study tells us that students who have bad breath get high stress relatively as well. And, the stress index was also high and statistically significant. (p<0.001). The implications of this study are that psychological stress among adolescents has a close relationship with oral health and health behavior.

The purpose of this study was to examine the self-rated oral health status and oral health concern of 6,094 adults over the age of 19, which were both related to subjective oral health awareness, based on the second-year (2008) raw data of the 4th National Health and Nutrition Survey. 1. As for subjective oral health awareness, 49.4 percent replied they were in bad oral health when they were asked about self-rated oral health status. Regarding oral health concern, 62.6 percent answered they were sort of concerned about oral health. 2. As to oral health indexes by sociodemographic characteristics, there were statistically significant differences in oral health indexes according to gender, age, academic credential, monthly mean household income, frequency of eating between meals and toothbrushing frequency. Smoking made no statistically significant differences to oral health indexes (p<0.000). 3. Concerning self-rated oral health status by sociodemographic characteristics, no significant differences were found according to gender, age and academic credential, and there were statistically significant differences according to monthly mean household income and smoking (p<0.000), frequency of eating between meals (p<0.018), toothbrushing frequency (p<0.003). 4. In relation to oral health concern by sociodemographic characteristics, gender and smoking made no significant differences, and statistically significant differences were found according to age (p<0.003), academic credential, monthly mean household income, frequency of eating between meals and toothbrushing frequency (p<0.000). 5. In regard to the relationship between subjective oral health awareness and oral health indexes, none of the oral health indexes had a significant relationship to self-rated oral health status, and there were statistically significant differences in oral health concern according to functioning teeth index (p<0.011) and community periodontal index (p<0.017).

Objectives: Unmet needs for dental treatment are one of the potential contributing factors to poor oral health because oral health problems worsen if left untreated. This study aimed to demonstrate the prevalence of and the causes for unmet dental needs, and to evaluate the association between unmet needs for dental treatment and oral health status. Methods: Data on 3,883 subjects aged ${\geq}18years$ from the Korean National Oral Health Survey 2006 were analyzed. Information regarding unmet needs for dental treatment was obtained using standardized questionnaires. Eight trained dentists examined decayed, missing, or filled teeth (DMFT). Multiple regression models were built to assess the association between unmet needs for dental treatment and the DMFT scores. Results: The prevalence of perceived unmet needs for dental treatment was 34.7% among the adult Korean population. Economic constraints were the main cause (38.6%) for unmet dental needs. The average DMFT scores were higher in the subjects with unmet needs for dental treatment than in those without. In individuals with unmet needs for dental treatment within the past 1 year, the number of decayed teeth after adjusting for confounders was likely to be greater by 0.58 and that of missing teeth by 0.27 compared to that in their counterparts with no unmet dental needs in the past 1 year. Conclusions: Perceived unmet needs for dental treatment were significantly associated with poor oral health status among the adult Korean population. Further studies are needed to clarify the direct and indirect effects of unmet needs for dental treatment on an individual's oral health status by investigating critical variables of the causal pathways among perceived dental needs, dental care utilization, and oral health status.

The purpose of this study was to investigate the prevalence of dental caries, periodontal status, and self-perceived oral health status of students in juvenile protection education institutions. The subjects of this study were 342 adolescents aged 13-20 years detained in two juvenile protection education institutions located in Gyeonggi Province. The study involved an oral examination to record decayed, missing, filled teeth and index teeth with bleeding, calculus, or periodontal pocket, combined with a questionnaire to investigate self-perceived oral health status. The main findings are as follows. 1. When compared with the result of National oral health survey, the students detained had more decayed teeth, DMFT, and teeth with bleeding, calculus, and shallow pocket than general population of the same age. 2. Female students showed more DMFT, more teeth with healthy periodontium, and fewer teeth with shallow pocket than male students (p<0.05). 3. Female students perceived their health to be poorer than male students (p<0.05). A majority(79.2%) of detainee valued their oral health in their life. 4. A majority(71.5%) of detainee reported their dental anxiety, and more female adolescents showed dental anxiety than male adolescents(p<0.05).
