This case-control study aimed to compare patients with temporomandibular disorders (TMD) and healthy controls in terms of oral health-related quality of life (OHRQoL) considering Graded Chronic Pain Scale (GCPS) scores, pain duration, psychological impairment and demographic characteristics.
A total of 75 patients with TMD and 75 healthy controls were recruited. The short version of Oral Health Impact Profile (OHIP-14) was administered for evaluating the OHRQoL. Psychosocial impairments were assessed using the General Health Questionnaire-28 (GHQ-28). The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) axis I and II were also used for patient diagnosis and collecting GCPS scores, pain duration, age and gender. Independent-sample t tests, Pearson's chi-square tests and multiple logistic and linear regression models were applied for statistical analysis.
The mean age of the patients was 34.3±12.4 years. A female-to-male ratio of 6:1 was seen in the TMD group. The prevalence and severity of the OHIP were significantly different between the TMD and control groups (66.7% vs 12.0% and 18.0 vs 9.2, respectively). According to multiple logistic regression for OHIP prevalence and multiple linear regression for OHIP severity in the TMD group, GCPS scores and pain duration, followed by psychological impairment, were the most important predictors of the OHRQoL.
TMD negatively affected the OHRQoL, particularly in patients with psychological impairments. Meanwhile, age and gender did not seem to have a serious effect. Hence, promoting the quality of life of patients with TMD requires emphasis on chronic pain management and maintaining good mental health.
本病例对照研究旨在根据分级慢性疼痛量表（GCPS）评分、疼痛持续时间、心理损害和人口统计学特征，比较颞下颌关节紊乱病（TMD）患者与健康对照者在口腔健康相关生活质量（OHRQoL）方面的差异。
共招募了75例TMD患者和75名健康对照者。采用口腔健康影响程度简表（OHIP-14）评估OHRQoL。使用一般健康问卷-28（GHQ-28）评估心理社会损害。颞下颌关节紊乱病研究诊断标准（RDC/TMD）轴I和轴II也用于患者诊断，并收集GCPS评分、疼痛持续时间、年龄和性别信息。采用独立样本t检验、Pearson卡方检验以及多元逻辑回归和线性回归模型进行统计分析。
患者的平均年龄为34.3±12.4岁。TMD组的男女比例为6:1。TMD组和对照组之间OHIP的患病率和严重程度存在显著差异（分别为66.7%对12.0%和18.0对9.2）。根据TMD组中OHIP患病率的多元逻辑回归和OHIP严重程度的多元线性回归，GCPS评分和疼痛持续时间，其次是心理损害，是OHRQoL的最重要预测因素。
TMD对OHRQoL有负面影响，尤其是对有心理损害的患者。同时，年龄和性别似乎没有严重影响。因此，提高TMD患者的生活质量需要强调慢性疼痛管理和保持良好的心理健康。
