The present cross-sectional study aimed to investigate possible association between Rheumatoid Arthritis (RA) and Apical Periodontitis (AP).
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 AP. 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 AP.
A total of 1026 teeth were examined in the RA group and 45 of them was diagnosed as AP. In the control group, 1025 teeth were examined and 21 teeth were diagnosed as AP. 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 AP.
It can be concluded that patients with RA can be more prone to develop AP.
本横断面研究旨在探讨类风湿关节炎（RA）与根尖周炎（AP）之间可能存在的关联。
在表 1 中提到，纳入了 48 例确诊为 RA 的患者作为实验组。另外选择了 48 名年龄和性别匹配、无任何系统性疾病史的健康参与者作为对照组。所有患者均进行影像学和临床检查以诊断 AP 的存在。记录所有患者的数据如下：存在的牙齿数、患有 AP 的牙齿数、患有 AP 的患者数、接受根管治疗的牙齿数（RCT）和接受 RCT+AP 的患者数。采用卡方检验和 logistic 回归分析来确定 RA 和 AP 之间可能存在的关联。
在 RA 组共检查了 1026 颗牙齿，其中 45 颗被诊断为 AP。在对照组中，共检查了 1025 颗牙齿，其中 21 颗被诊断为 AP。结果发现，RA 组患有 AP 的牙齿比例（4.3%）明显高于对照组（2%）（比值比[OR]=2.193，P=0.003）。logistic 回归分析表明，RA 与 AP 显著相关。
可以得出结论，RA 患者更容易发生 AP。
