An epidemiologic study of clinical signs and symptoms of temporomandibular disorders (TMD) was conducted with a probability sample of adults enrolled in a major health maintenance organization (HMO). This report presents data from a first wave field examination and interview conducted by trained, calibrated dental hygienist field examiners. Significant gender differences for vertical jaw opening measures were observed but no significant age differences were found for the distribution of clinically relevant findings. Clinic cases showed smaller amounts of vertical range of jaw motion but did not differ from community cases or controls on extent of lateral, protrusive, or retrusive mandibular movements; on classification of occlusion; or on dentally related variables. Clinic cases had more pain during all jaw excursions as well as during muscle and joint palpation. Joint clicking sounds were also observed more frequently in clinic cases.
对参加一家大型健康维护组织（HMO）的成年概率样本进行了颞下颌关节紊乱症（TMD）临床体征和症状的流行病学研究。本报告呈现了由经过培训且校准过的牙科保健员现场检查员进行的首轮现场检查和访谈的数据。观察到垂直颌开口测量存在显著性别差异，但在临床相关发现的分布上未发现显著年龄差异。临床病例的颌运动垂直范围较小，但在侧向、前伸或后缩下颌运动程度、咬合分类或与牙齿相关变量方面与社区病例或对照无差异。临床病例在所有颌运动过程以及肌肉和关节触诊时疼痛更多。临床病例中关节弹响音也更频繁出现。
