The objective of this study was to describe the frequency of TMD diagnoses in a patient population for comparison with the available literature.
Five hundred twenty consecutive patients seeking TMD treatment underwent a Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) assessment. The prevalence and age distribution of the different RDC/TMD axis I and II diagnoses were described.
Muscle disorders, disk displacements, and other joint disorders were diagnosed respectively in 56.4%, 42.0%, and 57.5% of patients. Sixty percent of patients had depression symptoms, 76.6% had somatization, and 21.8% presented high levels of pain-related impairment. Disk displacements were more frequently diagnosed in the younger-aged, other joint disorders in the older-aged, and muscle disorders in the middle-aged subjects (ANOVA for mean age comparison, F = 3.355; P = .002).
These distribution frequencies of TMD diagnoses provide insight into the epidemiology of this disease.
本研究旨在描述颞下颌关节紊乱病（TMD）患者人群中的 TMD 诊断频率，并与现有文献进行比较。
520 例连续就诊的 TMD 患者接受了研究性诊断标准（RDC/TMD）评估。描述了不同 RDC/TMD 轴 I 和 II 诊断的患病率和年龄分布。
肌肉疾病、关节盘移位和其他关节疾病分别在 56.4%、42.0%和 57.5%的患者中诊断。60%的患者有抑郁症状，76.6%有躯体化症状，21.8%的患者疼痛相关障碍程度较高。关节盘移位在年轻患者中更为常见，其他关节疾病在老年患者中更为常见，而肌肉疾病在中年患者中更为常见（平均年龄比较的方差分析，F = 3.355；P =.002）。
这些 TMD 诊断的分布频率为该疾病的流行病学提供了一些见解。
