目的探讨类风湿关节炎(rheumatoid arthritis,RA)与慢性牙周炎(chronic periodontitis,CP)之间的关系。方法选择2014年1月至2015年1月于中国医科大学附属第四医院风湿免疫科确诊为RA的患者30例(RA组)和同期于中国医科大学附属第四医院体检中心进行常规体检者23例(对照组),两组在性别及年龄上相匹配。检测两组患者的菌斑指数(plaque index,PLI)、出血指数(bleeding index,BI)、探诊深度(probing depth,PD)、附着丧失(attachment loss,AL)、缺失牙数等牙周指标,比较两组患者牙周状况、CP患病率及中、重度牙周炎的分布情况。结果 RA组患者PLI、AL、缺失牙数、CP患病率及中、重度牙周炎比例均高于对照组(均P<0.05),而两组BI、PD的差异无统计学意义(P>0.05)。结论 RA患者比正常人群的牙周状况差,且其患中、重度牙周炎的比例要高于正常人群。
Objective To investigate the relationship between rheumatoid arthritis (RA) and chronic periodontitis (CP). Methods Thirty patients (RA group) diagnosed as rheumatoid arthritis at the Fourth Affiliated Hospital of China Medical University from January 2014 to January 2015 were enrolled in the routine physical examinations at the Physical Examination Center of the Fourth Affiliated Hospital of China Medical University Cases (control group), the two groups match in terms of gender and age. The plaque index (PLI), bleeding index (BI), probing depth (PD), attachment loss (AL), number of missing teeth and other periodontal indexes The periodontal status, CP prevalence and the distribution of moderate and severe periodontitis in both groups were compared. Results The percentage of PLI, AL, the number of missing teeth, the prevalence of CP and the number of moderate and severe periodontitis in RA group were higher than those in control group (all P <0.05), while there was no significant difference between the two groups > 0.05). Conclusion The periodontal status of RA patients is worse than that of normal people, and the proportion of patients with moderate and severe periodontitis is higher than that of normal people.
