Abstract

Background: Although psychosocial and behavioural factors in temporomandibular disorders (TMDs) are well documented, ethnic variations remain underexplored, particularly within multiracial populations.

Objectives: This study aimed to compare TMD symptoms, oral behaviours, and psychosocial characteristics across ethnic groups, examine interrelationships between physical-psychosocial variables, and identify factors influencing TMD pain and oral behaviours in young adults.

Methods: Participants, recruited from a large public university, completed an online survey comprising sociodemographic information, the Five TMD Symptoms screener, Short-form Fonseca Anamnestic Index, Oral Behaviour Checklist, Big-Five Personality Inventory-10, Patient Health Questionnaire-4, and 15. Data were evaluated using the Chi-square test, non-parametric tests/correlation, and logistic regression (α = 0.05).

Results: The study included 766 individuals (mean age: 21.1 [SD 1.8]; 65.8% women) with an ethnic distribution of 58.4% Malay (M), 36.2% Chinese (C), and 5.5% Indian (I). Of these, 34.1% reported no TMD symptoms, while 8.5%, 29.1%, and 28.3% had intra-articular, pain-related, and combined symptoms, respectively. Moderate-to-severe psychological distress affected 21.3%, and 16.6% experienced moderate-to-severe somatization. No significant differences were found in TMD symptom type/severity or frequency of oral behaviours. However, notable variations in personality traits, psychological distress (I/M > C; p = 0.018), and somatization (M > C; p = 0.001) were observed among the three ethnic groups. Moderate correlations were detected between oral behaviours, psychological distress, and somatization (rs = 0.42-0.53).

Conclusions: In young adults, both TMD pain and high oral overuse behaviour are linked to psychological distress (ORs < 1.19) and somatization (ORs < 1.14). Ethnicity was not independently associated but may still hold relevance in multicultural contexts.

年轻人颞下颌障碍症状、口腔行为、人格特征和社会心理特征的种族差异：来自比较分析的见解

背景：虽然颞下颌疾病（TMDs）的社会心理和行为因素有很好的文献记载，但种族差异仍未得到充分研究，特别是在多种族人群中。目的：本研究旨在比较不同种族的TMD症状、口腔行为和社会心理特征，检查身体-社会心理变量之间的相互关系，并确定影响年轻人TMD疼痛和口腔行为的因素。方法：从一所大型公立大学招募的参与者完成了一项在线调查，包括社会人口学信息、TMD五种症状筛查、简短的Fonseca记忆指数、口腔行为检查表、大五人格量表-10、患者健康问卷-4和15。采用卡方检验、非参数检验/相关检验和logistic回归对资料进行评价（α = 0.05）。结果：该研究纳入766例个体（平均年龄：21.1岁[SD 1.8]； 65.8%为女性），种族分布为58.4%马来(M)， 36.2%华人(C)和5.5%印度(I)。其中34.1%的患者没有TMD症状，而8.5%、29.1%和28.3%的患者分别有关节内、疼痛相关和合并症状。21.3%的患者有中度至重度心理困扰，16.6%的患者有中度至重度躯体化。在TMD症状类型/严重程度或口腔行为频率方面无显著差异。然而，人格特质、心理困扰（I/M > C, p = 0.018）和躯体化（M > C, p = 0.001）在三个民族之间存在显著差异。口腔行为、心理困扰和躯体化之间存在中度相关性（rs = 0.42-0.53）。结论：在年轻人中，TMD疼痛和高剂量的口腔过度使用行为与心理困扰（ORs）有关

期刊介绍： Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
