Abstract

Background: This study developed and tested a multi-dimensional model for evaluating the severity of temporomandibular disorders (TMDs) based on the five core symptoms (5Ts) of the Diagnostic Criteria for TMDs (DC/TMD).

Methods: Study participants were sourced from a university hospital. The 5Ts screener was expanded to include the dimensions of duration, frequency, intensity, and interference with daily activities (5Ts-4D). The 5Ts-4D, along with the Graded Chronic Pain Scale (GCPS), Jaw Functional Limitation Scale-8 (JFLS-8), and Oral Health Impact Profile for TMDs (OHIP-TMD), was administered to individuals with no (NT), intra-articular (IT), pain-related (PT), and combined (CT) TMDs as determined using the DC/TMD methodology and diagnostic algorithms. Reliability and validity testing were carried out thereafter (α = 0.05).

Results: Among the 324 participants, 13.6% had NT, while 42.9%, 15.7%, and 27.8% were diagnosed with IT, PT, and CT, respectively. The 5Ts-4D demonstrated good internal consistency (Cronbach's alpha = 0.83-0.95) and moderate-to-good test-retest reliability (ICC = 0.51-0.97) across various symptom-dimension combinations. It also showed robust known-group differences (PT, CT, IT>NT) and convergent validity, with strong correlations between global TMD severity, JFLS-8, and OHIP-TMD (r_s = 0.68-0.78).

Conclusions: The 5Ts-4D, with its strong reliability and robust validity, holds promise as a straightforward tool for evaluating TMD symptoms and severity, thereby contributing to more effective management of TMD patients.

评估颞下颌紊乱严重程度：一个四维模型。

背景：本研究基于《颞下颌疾病诊断标准》（DC/TMD）的5个核心症状（5Ts），建立并检验了评估颞下颌疾病（TMDs）严重程度的多维模型。方法：研究对象来自一所大学医院。5Ts筛查扩展到包括持续时间、频率、强度和对日常活动的干扰（5Ts- 4d）等维度。5Ts-4D以及分级慢性疼痛量表（GCPS）、颌功能限制量表-8 （JFLS-8）和口腔健康影响量表（OHIP-TMD），对使用DC/TMD方法和诊断算法确定的无（NT）、关节内（IT）、疼痛相关（PT）和合并（CT） TMDs的个体进行治疗。随后进行信度和效度检验（α = 0.05）。结果：在324名参与者中，13.6%患有NT， 42.9%， 15.7%和27.8%分别被诊断为IT， PT和CT。5Ts-4D量表在各症状维度组合中表现出良好的内部一致性（Cronbach's alpha = 0.83-0.95）和中等至良好的重测信度（ICC = 0.51-0.97）。它还显示了强大的已知组差异（PT， CT, It >NT）和收敛效度，总体TMD严重程度，JFLS-8和OHIP-TMD之间存在强相关性（rs = 0.68-0.78）。结论：5Ts-4D具有较强的信度和稳健的效度，有望成为评估TMD症状和严重程度的直接工具，从而有助于更有效地管理TMD患者。
