Objective:The present cross-sectional study aimed to investigate possible association between Rheumatoid Arthritis (RA) and Apical Periodontitis (AP). Methods: In table one it is mentioned 48 patients diagnosed with RA were included in the experimental group. Another 48 healthy age- and gender-matched participants who reported no history of any systemic disease were selected to form the control group. All the patients were examined radiographically and clinically to diagnose the presence of AR. The following data was recorded for all patients; the number of teeth present, the number of teeth with AP, the number of patients with AP, the number of patients with root canal treated teeth (RCT) and the number of patients with RCT+AP.The chi-square test and logistic regression analysis were used to determine the possible association between RA and AR. Results: A total of 1026 teeth were examined in the RA group and 45 of them was diagnosed as AR. In the control group, 1025 teeth were examined and 21 teeth were diagnosed as AR. It was found that the prevalence of teeth with AP (4.3%) was significantly higher in the RA group than the control (2%) (odds ratio [OR]=2.193, P=0.003). Logistic regression analysis showed that RA is significantly associated with AR. Conclusion: It can be concluded that patients with RA can be more prone to develop AR.
