Relationship between periodontitis and diabetes: a bibliometrics analysis

BACKGROUND: Diabetes and periodontitis are common chronic diseases, and the pathogeneses of the 2 diseases both involve chronic inflammation. The presence of either of the 2 diseases increases the risk of the other, while the treatment of 1 can reduce the risk of the other. This study sought to summarize the current status of research in this field via a bibliometric analysis. METHODS: The Science Citation Index Expanded (SCI-E) database was searched to retrieve relevant articles using the following search terms: “periodontitis” and “diabetes”. Citespace software was used to analyze the search results, including the number of citations, the distribution of the countries, institutions, and journals that published the articles, the distribution of the authors, and the use of keywords in the articles. RESULTS: A total of 2,151 articles, with 63,668 citations, were included in the analysis. The top 5 countries in terms of the number of published papers were the United States (US), China, Brazil, Japan, and the United Kingdom (UK), and the top 5 institutions in terms of the number of published papers were Columbia University, Sichuan University, the University of North Carolina, the University of Sao Paulo, and the University of Guarulhos. The top 5 authors in terms of the number of published papers were Loos, Park, Han, Wang, and Offenbacher. There was little cooperation overall. The top 3 journals in terms of the most published related articles were all periodontal disease-related journals. After periodontitis and diabetes, the most frequently used keywords were inflammation, and risk. CONCLUSIONS: More and more studies have been conducted on diabetes and periodontitis, and the current research mainly focuses on the treatment and management of these 2 diseases.
