This study sought to assess the clinical signs and subjective symptoms of TMD, including the occlusal condition. Recruited individuals included 123 patients (58 men, 65 women) aged 15 to 65 years (mean 38.6 years) who had been referred to the TMD department. Helkimo dysfunction, occlusal, and anamnestic indices were used to assess signs of TMD, occlusal condition, and symptoms, respectively. Relationships of occlusal factors with signs and symptoms of TMD were evaluated by Spearman's correlation test. Associations of TMD with sex and age distributions were assessed by Mann-Whitney and Spearman's test, respectively. The prevalence of signs and symptoms was as high as 75%. Occlusal factors had significant associations with signs and symptoms of TMD. Prevalence of TMD in the study population was high, without preference for age or sex. Occlusal factors may play a role in the etiology of TMD.
本研究旨在评估颞下颌关节紊乱病（TMD）的临床体征和主观症状，包括咬合状况。纳入的个体为123例年龄在15至65岁（平均38.6岁）之间被转诊至TMD科的患者（58名男性，65名女性）。采用赫尔基莫功能紊乱指数、咬合指数和既往史指数分别评估TMD体征、咬合状况和症状。通过斯皮尔曼相关性检验评估咬合因素与TMD体征和症状之间的关系。分别采用曼-惠特尼检验和斯皮尔曼检验评估TMD与性别和年龄分布的相关性。体征和症状的患病率高达75%。咬合因素与TMD的体征和症状存在显著关联。研究人群中TMD的患病率较高，无年龄或性别的偏好。咬合因素可能在TMD的病因中起作用。
