We compared joint pain (JP) in patients diagnosed with and without articular disc displacement without reduction (ADD) based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and identified the characteristics of each JP.
Fifty-eight patients with restricted mouth opening and pain in temporomandibular joint (TMJ) and with a magnetic resonance imaging diagnosis of ADD were selected. Diagnosis of ADD + JP and nonADD + JP was made with the use of the RDC/TMD.
A multiple regression analysis of the data disclosed a positive correlation between range of motion on maximum assisted mouth opening and visual analog scale (VAS) (severity of JP) in the ADD + JP group, and between chronic pain grade (CPG) and VAS in the nonADD + JP group. A significant difference was observed between ADD + JP and nonADD + JP groups in CPG; CPG was higher in the nonADD + JP than in the ADD + JP group.
It is suggested that JP related and unrelated to ADD can indicate different types of disease.
我们比较了根据颞下颌关节紊乱研究诊断标准（RDC/TMD）诊断的关节盘移位未复位（ADD）患者和无关节盘移位未复位患者的关节痛（JP），并确定了每种 JP 的特征。
选择了 58 例张口受限和 TMJ 疼痛且 MRI 诊断为 ADD 的患者。使用 RDC/TMD 诊断 ADD+JP 和非 ADD+JP。
对数据的多元回归分析显示，在 ADD+JP 组中，最大张口辅助运动幅度与视觉模拟量表（VAS）（JP 严重程度）呈正相关，在非 ADD+JP 组中，慢性疼痛分级（CPG）与 VAS 呈正相关。在 ADD+JP 和非 ADD+JP 组之间观察到 CPG 有显著差异；非 ADD+JP 组的 CPG 高于 ADD+JP 组。
提示与 ADD 相关和不相关的 JP 可能表明不同类型的疾病。
