Temporomandibular disorders (TMD) occur at an incidence of 5-12% in the general population. We aimed to investigate the rate of true-positives for a screening questionnaire for TMD (SQ-TMD) and differences in the characteristics between the true-positive and false-negative groups. Materials and.
Seventy-six individuals (16 men, 60 women; mean age, 41.1 ± 16.5 years) were selected from pa-tients with TMD who had visited the Temporomandibular Joint Clinic at Tokyo Medical and Dental University. The patients were assessed using a questionnaire that contained items on TMD screening (SQ-TMD); pain intensity (at rest, maximum mouth-opening, and chewing), as assessed using the visual analog scale (VAS); and TMD-related limitations of daily func-tion (LDF-TMD). A logistic regression analysis was performed to assess the factors potentially influencing the true-positive rate.
Of the 76 subjects, 62 (81.6%) were true-positive for the questionnaire based on the SQ-TMD scores. The mean VAS score for maximum mouth-opening and chewing and the mean LDF-TMD score were significantly greater in the true-positive group than those in the false-negative group. The results of the logistic regression analysis showed that only the VAS score for chewing was a statistically significant factor (P < 0.05).
The true-positive rate of TMD using SQ-TMD was very high. The results indicate that SQ-TMD can be used to screen TMD in patients with moderate or severe pain and difficulty in living a healthy daily life.
颞下颌关节紊乱病（TMD）在普通人群中的发病率为5%-12%。我们旨在调查TMD筛查问卷（SQ-TMD）的真阳性率以及真阳性组和假阴性组之间特征的差异。材料与方法：从东京医科齿科大学颞下颌关节诊所就诊的TMD患者中选取76例个体（16例男性，60例女性；平均年龄41.1±16.5岁）。使用包含TMD筛查项目（SQ-TMD）的问卷对患者进行评估；使用视觉模拟量表（VAS）评估静息、最大张口和咀嚼时的疼痛强度；以及TMD相关的日常功能受限情况（LDF-TMD）。进行逻辑回归分析以评估可能影响真阳性率的因素。结果：在76名受试者中，根据SQ-TMD评分，62例（81.6%）问卷结果为真阳性。真阳性组最大张口和咀嚼时的平均VAS评分以及平均LDF-TMD评分显著高于假阴性组。逻辑回归分析结果显示，只有咀嚼时的VAS评分是具有统计学意义的因素（P<0.05）。结论：使用SQ-TMD的TMD真阳性率非常高。结果表明，SQ-TMD可用于筛查有中度或重度疼痛以及难以健康地进行日常生活的患者中的TMD。
