Abstract

Background: Emerging research suggests that reduced Oral Health-Related Quality of Life (OHRQoL) in orthodontic patients may be more closely linked to Temporomandibular disorders (TMDs) than malocclusion severity.

Objectives: This study assessed the burden and severity of TMD symptoms in prospective orthodontic patients, examined their relationships with malocclusion severity, somatic symptoms, psychological distress, jaw function and OHRQoL, and identified factors associated with high jaw functional limitation (JFL) and low OHRQoL.

Methods: Participants completed a survey covering demographics, the Five TMD Symptoms-Burden screener, Short-form Fonseca Anamnestic Index, Somatic Symptom Scale-8, Patient Health Questionnaire-4, Jaw Functional Limitation Scale-8 and Oral Health Impact Profile-14. Data were matched to the Index of Orthodontic Treatment Need (IOTN) and nature of malocclusion, then analysed using Chi-square/non-parametric tests and multivariate regression (α = 0.05).

Results: Of the 296 participants (mean age 21.6 [SD = 5.6]; 58.1% female), 40.2% had no TMD symptoms, while 15.4% experienced intra-articular, 8.8% pain-related and 35.5% combined symptoms. Significant differences in age, within-race patterns, TMD symptom burden/severity, IOTN-aesthetic component, somatic symptom burden, psychological distress, JFL and OHRQoL were observed. Moderate correlations were found between TMD burden and TMD severity, somatic burden and OHRQoL (r_s = 0.45-0.67), as well as between TMD severity and somatic burden (r_s = 0.42).

Conclusions: High JFL was significantly associated with age, sex, race, TMD symptom severity and the nature of malocclusion. Conversely, low OHRQoL was significantly related to age, somatic symptom burden and JFL. Routine TMD screening is essential for prospective orthodontic patients given their high prevalence.

前瞻性正畸患者的颞下颌紊乱症状：与治疗需求、社会心理困扰、颌功能和口腔健康相关生活质量的相关性

背景：新的研究表明，正畸患者口腔健康相关生活质量（OHRQoL）的降低与颞下颌疾病（TMDs）的关系可能比错牙合严重程度更密切。目的：本研究评估正畸患者TMD症状的负担和严重程度，探讨其与错颌严重程度、躯体症状、心理困扰、颌功能和OHRQoL的关系，并确定高颌功能限制（JFL）和低OHRQoL的相关因素。方法：参与者完成了一项调查，包括人口统计学，五种TMD症状-负担筛查，简短的Fonseca记忆指数，躯体症状量表-8，患者健康问卷-4，颌骨功能限制量表-8和口腔健康影响概况-14。将数据与正畸治疗需求指数（Index of Orthodontic Treatment Need， IOTN）和错牙合的性质进行匹配，采用卡方/非参数检验和多元回归分析（α = 0.05）。结果：在296名参与者中（平均年龄21.6岁[SD = 5.6]， 58.1%为女性），40.2%无TMD症状，15.4%有关节内症状，8.8%有疼痛相关症状，35.5%有合并症状。年龄、种族内模式、TMD症状负担/严重程度、ion -美学成分、躯体症状负担、心理困扰、JFL和OHRQoL存在显著差异。TMD负担与TMD严重程度、躯体负担和OHRQoL呈正相关（rs = 0.45 ~ 0.67）， TMD严重程度与躯体负担呈正相关（rs = 0.42）。结论：高JFL与年龄、性别、种族、TMD症状严重程度及错牙合性质有显著相关。相反，低OHRQoL与年龄、躯体症状负担和JFL显著相关。常规TMD筛查是必要的前瞻性正畸患者，因为他们的高患病率。

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.
