the relationship between rheumatoid arthritis and periodontal disease is crucial and has been explained via a complex interplay of genetic, environmental, and hormonal factors that influence the host immune tolerance leading to both disease characteristics. The aim of this study is to clinically investigate the correlation between the levels of anti-citrullinated protein antibodies (ACPAs) in gingival crevicular fluid and the severity of periodontal disease and rheumatoid arthritis in rheumatoid arthritis (RA) patients

the relationship between rheumatoid arthritis and periodontal disease is crucial and has been explained via a complex interplay of genetic, environmental, and hormonal factors that influence the host immune tolerance leading to both disease characteristics.

The aim of this study is to clinically investigate the correlation between the levels of anti-citrullinated protein antibodies (ACPAs) in gingival crevicular fluid and the severity of periodontal disease and rheumatoid arthritis in rheumatoid arthritis (RA) patients Materials and Methods: a total of 62 participants suffering from periodontitis and rheumatoid arthritis will be referred from the Badr Hospital (Faculty of Medicine, Helwan University) to Misr international university's dental clinic complex. Gingival crevicular fluid (GCF) samples will be collected from the patients . Assessment of ACPAs will be quantified using enzyme-linked immunoassay (ELISA) as the primary outcome Assessment of 2ry outcomes includes clinical periodontal and RA parameters
