Description: Oral microbiota differ significantly among patients with new-onset rheumatoid arthritis (NORA), patients with chronic rheumatoid arthritis (CRA), and healthy control participants, and between individuals with healthy gingiva versus periodontal diseases (PD), at the level of both genus and species/operational taxonomic unit (OTU).
