OBJECTIVE
The aim of this study was to evaluate the performance of research diagnostic criteria for temporomandibular disorders (RDC/TMD) as a diagnostic test for temporomandibular joint problems using magnetic resonance imaging (MRI) as the gold standard.
STUDY DESIGN
Sixty-seven women were assessed with RDC/TMD (2 examiners) and underwent MRI examination (3.0 T). Images were evaluated by 2 independent radiologists blinded to the clinical diagnoses. Results were analyzed by the Catmaker system.
RESULTS
Of the 67 patients, 44 were diagnosed with temporomandibular disorders (TMD) according to RDC/TMD, but 21 (32%) of the diagnoses were not confirmed by MRI. The RDC/TMD sensitivity was 83.0%, specificity was 53.0%, and the positive likelihood ratio was 1.77, whereas the negative likelihood ratio was 0.32 (P = 0.16).
CONCLUSIONS
Our data suggest that RDC/TMD is a good research tool, but the high rate of false-positive results limits its use in clinical practice.
目的
本研究旨在评估研究性诊断标准（RDC/TMD）作为磁共振成像（MRI）金标准的颞下颌关节问题诊断测试的性能。
研究设计
67 名女性接受了 RDC/TMD（2 名检查者）和 MRI 检查（3.0T）。图像由 2 名独立的放射科医生评估，他们对临床诊断不知情。结果由 Catmaker 系统进行分析。
结果
在 67 名患者中，根据 RDC/TMD 诊断为颞下颌关节紊乱（TMD）的有 44 例，但其中 21 例（32%）的诊断未被 MRI 证实。RDC/TMD 的灵敏度为 83.0%，特异性为 53.0%，阳性似然比为 1.77，而阴性似然比为 0.32（P=0.16）。
结论
我们的数据表明，RDC/TMD 是一种很好的研究工具，但高假阳性率限制了其在临床实践中的应用。
