Relationship between usage of removable denture and depression in Korean adults with loss of multiple teeth: A cross-sectional study using the seventh Korea National Health and Nutrition Examination Survey

Abstract

The purpose of this study is to evaluate the relationship between removable denture and depression. This study aims to investigate the relationship between depression and each group by dividing them into a group that were using removable dentures and a group that needed removable dentures but were not using removable dentures. Materials and methods: This study was conducted using raw data from the 7th Korea National Health and Nutrition Examination Survey (KNHNES). By using variables related to the state of the prosthesis and the need for prosthesis among oral examination data, the oral examination data were classified into two groups; group using removable denture and group in need of removable dentures. In addition, the variables of depression were classified into normal (0-4), mild depression (5-9), moderate depression (10-19), and severe depression (20-27) using the values of PHQ-9. For statistical analysis, logistic regression analysis was performed using SAS 9.4. Results: In the group in need of removable dentures, the risk of severe depression was statistically and significantly higher than the group using removable dentures. Conclusion: In patient who have lost multiple teeth, rehabilitation of the missing area with removable dental prosthesis is expected to decrease the occurrence of severe depression. (J Korean

Longitudinal Association Between Oral Status and Depressive Symptoms Among Chinese Older Adults — China, 2014–2018

“…Our findings were consistent with prior studies (9)(10)(11)(12). A prospective longitudinal study found that older adults in Brazil who experienced tooth loss were at greater risk of exhibiting depressive symptoms (9).…”

“…In a Japanese longitudinal study, having no teeth could play a role in worsening depressive symptoms in individuals aged 65 years and older (10). Another study pointed out that a deterioration in oral health increased the risk of depressive symptoms among a group of older adults in England (11). In addition, a cross-sectional study of the Republic of Korea reported that the use of dental prosthesis in patients with the loss of multiple teeth was expected to reduce the likelihood of severe depression (12).…”
