Clinical and CT scan abnormalities of the temporomandibular joint in rheumatoid arthritis have been little studied in the literature. The temporomandibular joint was examined clinically and by CT scan in 26 patients with rheumatoid arthritis and 26 controls. In the rheumatoid arthritis group, 61.2% of patients had physical signs of temporomandibular disease as compared with 42.3% of the controls. 88.4% of rheumatoid arthritis had erosive or geodic lesions of the temporomandibular joint by CT scan as compared with 57.6% of the controls (p less than 0.05). The temporomandibular clinical score was not correlated with CT scan score in rheumatoid arthritis. CT scan score was correlated with the number of basic drugs used, rheumatoid factor levels and radiological scores of the hands and cervical spine. The authors feel that the only CT scan abnormalities specific to rheumatoid arthritis consist of erosive and geodic lesions of the mandibular condyle, that there is no correlation between clinical and CT scan abnormalities of the temporomandibular joint in rheumatoid arthritis and that the extent of destructive lesions of the temporomandibular joint by CT scan in rheumatoid arthritis is closely correlated with the severity of the disease.
类风湿关节炎颞下颌关节的临床及CT扫描异常在文献中鲜有研究。对26例类风湿关节炎患者和26名对照者进行了颞下颌关节的临床检查及CT扫描。在类风湿关节炎组中，61.2%的患者有颞下颌疾病的体征，而对照组为42.3%。通过CT扫描，88.4%的类风湿关节炎患者有颞下颌关节侵蚀性或地图状病变，而对照组为57.6%（p<0.05）。类风湿关节炎患者的颞下颌临床评分与CT扫描评分无相关性。CT扫描评分与所用基础药物数量、类风湿因子水平以及手部和颈椎的放射学评分相关。作者认为，类风湿关节炎特有的CT扫描异常仅包括下颌髁突的侵蚀性和地图状病变，类风湿关节炎患者颞下颌关节的临床和CT扫描异常之间无相关性，且类风湿关节炎患者颞下颌关节CT扫描的破坏病变程度与疾病严重程度密切相关。
