Background: Rheumatoid arthritis is an autoimmune disease, associated with a chronic inflammatory status, and an increased level of cytokines which are implicated in the destruction of joints. Periodontal disease is an infection of the tissue that surrounds and supports the tooth structure, resulting also in a chronic inflammatory status. An association between the two diseases has been reported in numerous studies. Objectives: The goal of this study was to examine the prevalence of periodontal disease among rheumatoid arthritis patients in Qatar, along with investigating the association between the two diseases. Methods: A total of 92 participants (43 cases with rheumatoid arthritis and 49 controls without rheumatoid arthritis) were recruited from the outpatient rheumatology clinic at Hamad Medical Corporation in Doha, Qatar. The ACR/EULAR 2010 for the diagnosis criteria for rheumatoid arthritis were used to diagnose participants. Results: The overall prevalence of periodontal disease was 73.9% (95% CI: 64.2 to 82.1). The percentage of periodontal disease was observed to be higher among the rheumatoid arthritis group compared to the non-rheumatoid arthritis group (76.7% vs 71.4%; p=0.562). Patients older than 50 years of age were significantly associated with an increased risk for periodontal disease [unadjusted OR=4.11; 95% CI (1.42, 11.43); p=0.009]. Having rheumatoid arthritis [unadjusted OR=1.32; 95% CI (0.52, 3.38); p=0.563], females [unadjusted OR=1.55; 95% CI (0.51, 4.74); p=0.437], rheumatoid disease duration more than 10 years [unadjusted OR= 1.33; 95% CI (0.32, 5.59); p=0.684], and body mass index of less than 30 [unadjusted OR=1.17; 95% CI (0.46, 3.01); p=0.740] were positively associated with an increased risk for periodontal disease. Conclusions: This is the first study to assess periodontal disease among rheumatoid arthritis patients in Qatar. Future work might need to involve a larger, more representative sample.
