Abstract

Objective: To assess the risk of low bone mineral density (BMD), evaluated by mandibular cortical index (MCI), W-index (WI), and the continuity of the mandibular canal cortices in rheumatoid arthritis (RA) patients in comparison with healthy subjects.

Material and methods: A retrospective and comparative study was conducted in individuals diagnosed with rheumatoid arthritis (Study Group-SG) and healthy individuals without comorbidities (Control Group-CG). MCI, WI, and the continuity of the mandibular canal cortices were evaluated by two experienced observers. Conditional logistic regression was performed to verify associations between MCI and other variables.

Results: The study included 37 RA patients and 37 healthy controls, matched by sex, age, and ethnicity. Six patients from each group were considered C1 (without BMD reduction in mandibular cortical bone). No differences between the BMD were detected for WI (p = 0.54). The odds ratio analysis did not demonstrate associations between the lower MCI and the variables: presence of RA, ethnicity, sex, glucocorticoid, bisphosphonate intake, and the mandible cortices continuity.

Conclusion: Most individuals with RA had altered MCI, but no association was observed between the variables studied.

类风湿关节炎患者的下颌骨成像评估：一项比较横断面研究。

目的：通过下颌皮质指数（MCI）、w指数（WI）和下颌管皮质连续性评估类风湿关节炎（RA）患者低骨密度（BMD）的风险，并与健康受试者进行比较。材料和方法：在诊断为类风湿关节炎的个体（研究组- sg）和无合并症的健康个体（对照组- cg）中进行回顾性和比较研究。MCI， WI和下颌管皮质的连续性由两名经验丰富的观察员进行评估。使用条件逻辑回归来验证MCI与其他变量之间的关联。结果：该研究包括37名RA患者和37名健康对照者，按性别、年龄和种族匹配。每组6例患者为C1级（下颌皮质骨无骨密度降低）。WI与BMD之间无差异（p = 0.54）。优势比分析没有显示低MCI与以下变量之间的关联：RA的存在、种族、性别、糖皮质激素、双膦酸盐摄入量和下颌骨皮质连续性。结论：大多数RA患者的MCI发生了改变，但所研究的变量之间没有发现关联。
