To analyze the relationship between symptoms and signs of temporomandibular disorders (TMD) and the patients' quality of life (QOL).
A total of 492 TMD patients were included in this study. The clinical examination results were recorded using Fricton index of temporomandibular joint function. "Visual analog scale (VAS) evaluation of QOL disturbance" was designed to quantitate patients' QOL, to evaluate the degree that the patients QOL was affected.
Chewing, daily life and emotion among all 8 items of QOL were frequently affected by TMD, and joint clicking had the least influence on QOL. Intermittent closed lock had more severe interference with QOL than joint clicking only. Severe and moderate pain or limited mouth opening affected the QOL more severely than mild pain or mild limited mouth opening. The simple linear relationship between Fricton index and patients' QOL was poor (r < 0.4).
Pain is the most frequently seen symptom in TMD. TMD could affect patients' QOL, including both physical and social-psychological functions. The results suggest that the patients' QOL as well as TMD symptoms and signs should be considered in the management of TMD.
分析颞下颌关节紊乱病（TMD）的症状体征与患者生活质量（QOL）之间的关系。
本研究共纳入492例TMD患者。采用颞下颌关节功能Fricton指数记录临床检查结果。设计“生活质量干扰视觉模拟量表（VAS）评估”来量化患者的生活质量，评估患者生活质量受影响的程度。
在生活质量的所有8项内容中，咀嚼、日常生活和情绪受TMD影响较为频繁，而关节弹响对生活质量的影响最小。间歇性闭口绞锁对生活质量的干扰比单纯关节弹响更严重。重度和中度疼痛或张口受限比轻度疼痛或轻度张口受限对生活质量的影响更严重。Fricton指数与患者生活质量之间的简单线性关系较差（r < 0.4）。
疼痛是TMD中最常见的症状。TMD可影响患者的生活质量，包括身体和社会心理功能。结果表明，在TMD的治疗中应考虑患者的生活质量以及TMD的症状体征。
