Research Status, Hotspots, and Trends on Oral Care Research in the Elderly in Mainland China Published from 2002-2022: A Bibliometric Analysis

Abstract

Background Oral health is a key indicator of overall health, well-being and quality of life. The oral health status of the elderly will decline with age, which results in serious consequences and bring heavy medical and economic burdens to the country and society. With the aggravation of population aging process, more and more attention has been paid to the oral health problems of the elderly in mainland China, the number of studies focusing on oral care for the elderly is increasing year by year, and many research papers have been published in journals. However, no scholar has conducted bibliometric analysis in this field so far. The purpose of this study is to analyze the status, hotspots and trends of research on oral care for the elderly in mainland China in the past 20 years through bibliometrics, which aims to provide new ideas and targets for future clinical work and research. Methods Relevant literature from January 2002 to May 2022 were retrieved from China National Knowledge Infrastructure, Wanfang, China Science and Technology Journal Database, Web of Science, and PubMed. NoteExpress 3.5.0.9054, Co-Occurrence 12.6 and CiteSpace 6.1.R2 were used to analyze bibliometric features in terms of year of publication, journal of publication, authors, institution and keywords. Results A total of 716 related articles were obtained. Data analysis revealed that the number of publications shows an increasing trend over time, only 2017–2021, 309 papers were published, accounting for 43.2% of the total number of publications. A total of 238 articles were published in Science Citation Index journals or Chinese core journals, accounting for 33.2% of the total number of articles, and only a few core journals among the top 10 journals. The study of oral health-related quality of life in the elderly is a hot research topic. There is a lack of research on the elderly living in elderly care facilities. Conclusion The present study provides an in-depth understanding of oral care in the elderly in mainland China. The study showed the current research status, hotspots and trends of this field, and future research direction is prospected.

As a result, it is unable to explore the underlying logic of interaction mechanisms and opinion generation rules among all parties involved in the Vlog field.…”
