Background: This study was aimed at reducing depression and improving the quality of life and oral health of the elderly Koreans by elucidating the effect of depression on their life quality and oral health. Methods: Original data from the 8th National Health and Nutrition Survey (2019) were analyzed and implemented. The elderly (age≥65years) Koreans were enrolled. The oral health status was determined using the Decayed, Missing, Filled Teeth (DMFT) index and subjective self-report. The quality of life was quantified as the sum of score of each item in the Euro Qol-5 dimension (EQ-5D) and Health-related Quality of Life Instrument with 8 Items (HINT-8). The t-test, one-way analysis of variance, correlation analysis, and multiple regression analysis were performed to statistically compare the quality of life, oral health status, and oral health status according to the depression status. Results: EQ-5D and HINT-8 scores differed significantly with the history of depression, current depression, stress perception, depression for 2 weeks, and annual suicidal intention (p≤0.05). The DMFT index score differed significantly with the depression diagnosis and depression for 2 weeks (p≤0.05). EQ-5D, HINT-8, and DMFT index differed significantly with all oral health behavior variables (p≤ 0.05). Conclusions: The results of this study could serve as a basis to formulate oral health programs for the elderly to reduce depression and improve the quality of life.

Purpose: This study conducted a survey on the elderly of 65 years and over with physical debilities and ones capable of living at home residing in Jeju Special Self-Government Province to compare and analyze demo-sociological characteristics and factors influencing on oral health related living quality. And also this study intended to provide basic data for developing effective public medical policies and health promotion programs to increase oral health related living quality of the elder. Methods: The elderly of 65 years and over living in Jeju Special Self-Government Province were interviewed individually from 7 February 2011 to 18 April and interview results of a total of 220 subjects were analysed for this study. Results: Current status of the elderly including ones with & without physical debilities influenced functional limitation and behavioral aspects of GOHAI criteria used in this study. The elderly with physical debilities experienced less limitation in food chewing and swallowing, and pronunciation than ones capable of living at home. On the analogy of the previous study(by Park, N. G., 2010) in which oral health related quality and satisfaction of life of the elderly with physical debilities were different due to their physical, circumstantial and psychological limitations, the former's oral health conditions are worse than the ones capable of living at home and because of medical care accessability limitation they suffer from deteriorated oral condition. By the comparison of factors influencing on the living quality relating to the oral health of the elderly with physical debilities and ones capable of living at home, 2 factors, age and living area, were meaningful factors commonly influencing on the oral health related living qualities of both. The elderly of 75 years and over were more affected by psychological and behavioral aspects of oral health related living quality than the ones of 65-74 years, and the ones living in country suffered from functional limitations, pains and discomfort more than ones in city. Additionally, being different from the elderly capable of living at home, the ones with physical debilities were influenced by the factors of average monthly income and medical security type. Conclusion: Improvement of programs and systems to increase oral health related quality of life needs to be carried out preferentially for the elderly of 75 years and over, and dwelling in country. Also this study suggests that the policy of paying the denture insurance allowance in 2012 need effective planning considering the elderly's current status, age, living area, medical security type.

Background: Increasing age and loss of teeth weaken oral muscle strength. This study aimed to investigate the positive effects of orofacial myofunctional training on elderly people. Methods: Thirty six elderly individuals in a welfare center and a senior citizen center were included in this study. A survey regarding lip and tongue strength suvsequent to orofacial myofunctional training and oral health-related quality of life was conducted from April to June, 2019. Data were analyzed using PASW statistics ver. 18.0. Results: The experimental group, showed an increase in lip strength (from 9.79 to 10.31) and tongue strength (from 41.26 to 43.97) after orofacial myofunctional training. The perception of oral health-relatedquality of life was enhanced (from 2.26 to 2.07). In particular, the frequency of dry cough for food removal while swallowing decresed due to an incresed in the secretion of saliva (p<0.05). Correlation analysis showed that the number of functional teeth was positively related to oral health-related quality of life. Conclusion: Orofacial myofunctional training for improving lip and tongue strength is effective in the elderly. In older societies, oral strength should be maintained to improve oral health-related quality of life. It also suggests the interest of oral health workers and applying orofacial myofunctional training programs.
