Abstract：
In this case-control study, we investigated the presence of differing numbers and types of temporomandibular disorder (TMD) symptoms, their association with psychological distress, and their impact on oral health-related quality of life (OHRQoL).
We recruited a total of 814 participants with TMD and 147 control subjects. The participants were instructed to complete the Diagnostic Criteria for Temporomandibular Disorders Symptom Questionnaire; the Depression, Anxiety and Stress Scale-21; and the Oral Health Impact Profile-Temporomandibular Disorders. The participants were subsequently categorized by their number and type of TMD symptoms. Data were analyzed with the Kruskal-Wallis/Mann-Whitney U test (α = .05).
The mean age of the participants (N = 961) was 32.99 ± 13.14 years, and 79.2% were women. Participants with more and all types of TMD symptoms generally exhibited significantly higher levels of psychological distress and worse OHRQoL (P < .001). Those with TMD pain plus temporomandibular joint (TMJ) sounds/dysfunction had significantly greater psychological distress, whereas those with painful symptoms and TMJ dysfunction experienced significantly more impairment in OHRQoL than individuals with only TMJ sounds.
Psychological states and OHRQoL are influenced by the number and type of TMD symptoms. Individuals with more and all types of pain-related TMD symptoms with/without intra-articular features had greater psychological distress and OHRQoL impairment.

摘要：
在这项病例对照研究中，我们调查了不同数量和类型的颞下颌关节紊乱病（TMD）症状的存在，他们与心理困扰的联系，以及它们对口腔健康相关生活质量（OHRQoL）的影响。
我们共招募了814名TMD参与者和147名对照受试者。参与者被指示完成颞下颌疾病诊断标准症状问卷；抑郁症，焦虑和压力量表-21；以及口腔健康影响概况-颞下颌疾病。随后根据TMD症状的数量和类型对参与者进行分类。用Kruskal-Wallis/Mann-WhitneyU检验(α=.05)分析数据。
参与者的平均年龄（N=961）为32.99±13.14岁，79.2%为女性。具有更多和所有类型的TMD症状的参与者通常表现出明显更高的心理困扰水平和更差的OHRQoL（P<.001）。那些TMD疼痛加上颞下颌关节（TMJ）声音/功能障碍的人有明显更大的心理困扰，而那些有疼痛症状和TMJ功能障碍的患者的OHRQoL受损明显多于仅有TMJ声音的患者。
心理状态和OHRQoL受TMD症状的数量和类型的影响。具有更多和所有类型的疼痛相关TMD症状且具有/不具有关节内特征的个体具有更大的心理困扰和OHRQoL损伤。
