Research hotspots and trends of oral health in older adults from 2013 to 2023: A bibliometric and visual analysis
Abstract
Background: Oral health problems seriously affect the quality of life of older adults. It is of great significance to investigate the statuses of oral health in older adults. The study aimed to analyze the current status, hotspots and frontiers of global oral health research in older adults through bibliometrics to provide references and guidance for future research in this field. Methods: Literature on oral health in older adults from 2013 to 2023 was retrieved from the Web of Science Core Collection (WoSCC) database. CiteSpace 6.2.R4 was used for bibliometric and visual analysis, including journal and co-cited journal, country/region, institution, author, co-cited references, and keyword analysis. Results: A total of 1430 publications related to oral health in older adults were included. The number of publications has gradually increased over the past decade. The most widely published and cited journal was Gerodontology. The most prominent contribution came from the United States of America, and the University of London and Hirohiko Hirano were the most prolific institution and author, respectively. The current research hotspots were summarized as oral hygiene interventions, oral health-related quality of life and oral health issues in older adults. Cohort studies of oral health, the relationship between oral health and frailty, and the correlation between oral health and nutritional status may be emerging research trends. Conclusions: This study systematically analyzed the hotspots and frontiers of oral health in older adults and called for increased collaboration among countries, institutions, and authors. In addition, oral hygiene interventions for older adults, oral health-related quality of life, oral health issues, cohort studies of oral health, and the relationship between oral health and frailty or nutritional status may be the focus of future research.
