BACKGROUND The aim of this study was to investigate the association of oral behaviors (OBs) with anxiety, depression, and jaw function in patients with temporomandibular disorders (TMDs) in China. MATERIAL AND METHODS A total of 537 patients diagnosed with TMD were included in this study (average age, 31.55±12.08 years; 86 men [16.0%] and 451 women [84.0%]). There were 31 cases of masticatory muscle pain, 459 cases of disc displacement, and 13 cases of arthralgia/arthrosis, and 34 cases were uncategorized. Patients were assessed using the Oral Behaviors Checklist (OBC), Jaw Functional Limitation Scale (JFLS), Generalized Anxiety Disorder-7 (GAD-7) scale, and Patient Health Questionnaire-9 (PHQ-9). The relationships between OBC scores and mouth opening, pain scores, JFLS, PHQ-9, and GAD-7 were evaluated with Spearman's correlation analysis. The median TMD symptom duration was 3 (0.5-154) months; men and women did not differ significantly in symptom duration or in the number of episodes of depression and anxiety. RESULTS The following OBs were common in patients with TMDs: "putting pressure on the jaw (52.9%)", "chewing food on 1 side (47.5%)", and "holding teeth together during activities other than eating (33.3%)". The OBC scores were significantly correlated with the JFLS, PHQ-9, and GAD-7 scores (P<0.01). CONCLUSIONS Patients with TMDs exhibit specific OBs, which are associated with depression, anxiety, and jaw function. It is necessary to further investigate the interaction of OBs with depression and anxiety in the development of TMDs.
本研究旨在探讨中国颞下颌关节紊乱病（TMD）患者口腔行为（OBs）与焦虑、抑郁和下颌功能的关系。
本研究共纳入 537 例 TMD 患者（平均年龄 31.55±12.08 岁；男 86 例[16.0%]，女 451 例[84.0%]）。其中咀嚼肌疼痛 31 例，髁突前移位 459 例，关节弹响/骨擦音 13 例，未分类 34 例。采用口腔行为检查表（OBC）、下颌功能限制量表（JFLS）、广泛性焦虑障碍 7 项量表（GAD-7）和患者健康问卷-9 项量表（PHQ-9）对患者进行评估。采用 Spearman 相关分析评估 OBC 评分与张口度、疼痛评分、JFLS、PHQ-9 和 GAD-7 的关系。TMD 症状持续时间的中位数为 3（0.5-154）个月；男性和女性在症状持续时间或抑郁和焦虑发作次数方面无显著差异。
TMD 患者常见的 OBs 包括：“下颌受压（52.9%）”、“单侧咀嚼（47.5%）”和“非进食时咬牙（33.3%）”。OBC 评分与 JFLS、PHQ-9 和 GAD-7 评分显著相关（P<0.01）。
TMD 患者存在特定的 OBs，与抑郁、焦虑和下颌功能有关。有必要进一步研究 OBs 与 TMD 发生发展中抑郁和焦虑的相互作用。
