Objectives: This study aimed to assess the association between the use of dentures by the elderly and the prevalence of depression by using the original data from the 2017 Community Health Survey as basic data for the promotion of oral health and oral health policy development in the elderly. Methods: The study subjects were 67,835 elderly over 65 years of age. The raw data were collected from 2017 Community Health Survey in Korea Center for Disease Control and Prevention. Results: Among the demographic and sociological characteristics, the higher the age, the lower the educational level, the worse the subjective health level, and the higher the denture use. The higher the age, the lower the education level, the lower the income level, the worse the subjective health level, the more stress they have, the more sleep time, and the higher the prevalence of depression. The association between the use of dentures and the prevalence of depression was 1.071 times higher than that of not using dentures, and it was found that the prevalence of depression was affected. Conclusions: As a result, it was confirmed that the use of dentures influenced the prevalence of depression. Institutional support will be needed to establish a national-level prevention policy that can maintain and promote healthy oral conditions and prevent the need dentures in the elderly.

Objectives: This study investigated the working conditions of dental hygienists and their challenges in providing oral care to older adults with dementia using focus group interviews. Methods: We collected data for approximately a month beginning from August 2020 and divided the study subjects into two groups: the health dental hygienist and the clinical dental hygienist groups. A total of 11 subjects participated in this study. Results: The oral health management of older adult patients with dementia has not been efficiently carried out in local communities or dental medical institutions. In addition, dental hygienists encounter difficulties in managing the oral health of these patients and hope to actively learn more about their special cases. Conclusions: Based on the results of this study, it is necessary to develop a manual or program for the professional implementation of oral health interventions for older adults with dementia.

Objectives: This study aimed to assess the relationship between dental care needs and dental service use in Korean elderly. Methods: Using the sixth Korea National Health and Nutrition Examination Survey, from 22,948 individuals, 1,572 (male 701, female 871) elderly individuals aged above 65 years were included in the study. All analyses were stratified by sex. Results: In males, the group with subjective needs was 3.74 (95% confidence interval [CI]: 2.58-5.41) times more likely to use dental services than the group without subjective needs. For females, the group with subjective needs was 2.17 (95% CI: 1.57-2.98 ) times more likely to use dental services than the group without subjective needs. Conclusions: To conclude, the elderly with symptoms, used the dental services for pain relief and functional recovery. Fundamental efforts to improve oral health are needed, such as providing treatment, prevention and educational services, besides efforts to provide treatment-oriented dental services. Further research is needed for the middle and elderly individuals who are in the blind spot of the existing policy.

Objectives: It is crucial to detect and prevent oral problems early. Older adults, in particular, should go for regular dental checkups to maintain a healthy oral environment. This study identified the factors affecting regular dental examinations and unmet dental needs in older adults. Methods: This study analyzed 3,362 older adults aged 65 or over using the data from the 7th Korean National Health and Nutrition Examination Survey (KNHANES). Frequency analysis was performed on general characteristics. In addition, chi-square tests were done to determine differences in regular dental checkups and unmet dental needs according to general characteristics. Logistic regression analysis was performed on factors influencing regular dental checkups and unmet dental needs. Results: Factors influencing regular dental checkups were statistically significant according to residential areas, level of education, household income, and levels of physical activity (p<0.05). Factors influencing unmet dental needs were statistically significant according to residential areas, level of education, private medical insurance, and levels of dental pain (p<0.05). Conclusions: National level policy strategies should be implemented to improve the oral health of older adults. These strategies should encourage regular dental checkups to effectively lower the rate of unmet dental needs.

Objectives: This study aimed to study the association between unmet dental treatment and depression in the dental area of the elderly. Methods: The data was from the 7th period of the National Health and Nutrition Examination Survey. Multiple logistic regression analysis was performed to evaluate the relationship between depression and unmet dental treatment when confounding factors such as income quintile and smoking were considered. Statistical software, SAS 9.4 version was used. Results: After correcting all confounding factors, the analysis showed that the experience of unmet dental treatment was 2.73 times more likely among depressed men and 2.52 times more likely among depressed women (p<0.05). Conclusions: The results of this study suggested that we should consider that depression in the elderly can affect unmet dental treatment regardless of gender.

Objectives: This study used secondary data from the 2021 Community Health Survey to identify the impact of dysphagia on mental health-related characteristics among older adults, selecting 73,970 individuals aged 65 years and older. Methods: Frequency analysis, χ²-test, and multiple logistic regression were conducted to identify risk factors affecting mental health-related characteristics among older adults. Results: Dysphagia was most common among individuals with the following demographic characteristics: female, aged 85 years and older, three-generation household and household income in the 1st quintile. Chewing discomfort according to mental health-related characteristics was higher in older adults with cognitive impairment and depression. Sex, age, education level, household income, and chewing discomfort were significant for cognitive impairment, whereas sex, age, household type, education level, household income, and chewing discomfort were significant for depression. Conclusions: The above results confirmed that chewing discomfort contributes to mental health issues such as cognitive impairment and depression. It is therefore necessary to recognize chewing discomfort as an important health problem affecting the mental health of older adults, and to develop a multifaceted dental hygiene approach to target community-dwelling older adults who suffer from chewing discomfort.

Objectives: The purpose of this study is to explore the research trends of elderly oral health through a language network analysis. Methods: A total of 354 published studies with 668 keywords were collected from the Research Information Sharing Service (RISS) between 2000 and 2022. Language network analysis was performed using Textom 6.0, Ucinet 6.774, and NetDraw 2.183. Results: The most frequent keywords were 'elderly', 'oral health', 'quality of life', and 'OHIP-14'. The result of frequency-inverse document frequent keywords showed similar results to the most frequent keywords. The N-gram of keywords shows that 'elderly', 'oral health' (18 times) and 'elderly', 'depression' (7 times). As a results of the analysis of degree centrality and between centrality, 'elderly', 'oral health', and 'quality of life' were found to be high. The CONCOR analysis identified the main clusters of 'quality of life', 'oral health behavior', 'health', and 'oral function disorder'. Conclusions: The results of the current study could be available to know research trends in elderly oral health and it is necessary to improve more comprehensive study in follow-up study.

The purpose of this study is to propose learning objectives in social dental hygiene by analyzing and reviewing learning objectives in oral health administration area of the existing public oral health. This study is a cross-sectional study. The subjects of the study selected with convenience extraction were 15 members of the social dental hygiene subcommittee of the Korean Society of Dental Hygiene Science. Data collection was conducted by self-filling questionnaire. The research tool is from 48 items of A division in the book of learning objectives in the dental hygienist national examination, and this study classified each of them into 'dental hygiene job relevance', 'dental hygiene competency relevance', 'timeliness', and 'value discrimination of educational goal setting' to comprise 192 items. Also, to collect expert opinions, this study conducted Delphi survey on 7 academic experts. Statistical analysis was performed using the IBM SPSS Statistics ver. 23.0 program (IBM Co., Armonk, NY, USA). Recoding was performed according to the degree of relevance of each learning objective and frequency analysis was performed. This study removed 18 items from the whole learning objectives in the dental hygienist national examination in the oral health administration area of public oral health. Fifteen revisions were made and 15 existing learning objectives were maintained. Forty-five learning objectives were proposed as new social dental hygiene learning objectives. The topics of learning objectives are divided into social security and medical assistance, oral health care system, oral health administration, and oral health policy. As a result of this study, it was necessary to construct the learning objectives of social dental hygiene in response to changing situation at the time. The contents of education should be revised in order of revision of learning objectives, development of competency, development of learning materials, and national examination.

The purposes of this study were to examine the effect of 35% Carbamide Peroxide(CP) bleaching agent on the changes in physical and chemical characteristics of tooth. The effect of bleaching agent on enamel was analyzed using Hardness test, SEM and EDS. The microhardness between bleached groups after bleaching showed statistically significant difference according to the paired t-test. The bleached enamel surface showed apparent morphological changes compared to the enamel, which was stored in distilled water only. The difference of the total mineral contents for the distilled water and Carbamide Peroxide did not show statistical significance. These results demonstrated that bleaching using 35% Carbamide Peroxide were adversely affects application time of experimental group and may the safety of using these agents for a short time in dentist-monitored bleaching.
