Recent studies have indicated a potential relationship between the oral microbiome and the onset and progression of RA. However, research trends in this area have not been comprehensively examined. The aim of this study was to conduct a bibliometric analysis of the relationship between RA and the oral microbiome from January 1, 1995, to January 10, 2024, to elucidate the research landscape, including hot topics and emerging trends.<h4>Methods</h4>We extracted literature related to RA and the oral microbiome from the Web of Science database. Utilizing CiteSpace software, we analyzed publications, countries, institutions, authors, and keywords through a visual knowledge graph to assess Frontiers in microbiology1589331https://www.ebi.ac.uk/biostudies/studies/S-EPMC12307397biostudies-literatureBibliometric and visualized analysis of the relationship between rheumatoid arthritis and periodontitis-related bacteria using CiteSpace software.PMC12307397Hu CLin TChen JYe BLi QWang XXu ZfalseBibliometric and visualized analysis of the relationship between rheumatoid arthritis and periodontitis-related bacteria using CiteSpace software.<h4>Background</h4>Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease of unknown etiology.
