The purpose of this study was to evaluate the relationship between temporomandibular joint (TMJ) effusion and joint pain in patients with internal derangement based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD).
A total of 240 TMJs from 120 patients with unilateral painful joints (103 females and 17 males, mean age 29.9 ± 12 years) were evaluated. Clinical assessments were carried out according to the DC/TMD guidelines. Magnetic resonance imaging (MRI) was used to evaluate the degree of effusion in each joint. The radiological and clinical findings were analysed for statistically significant correlations.
Although the results indicated a statistically significant association between moderate joint effusion and disc displacement (p < 0,05), there was no statistically significant association between moderate effusion and joint pain (p > 0,05). There were, however, statistically significant associations between marked effusion and both disc displacement and joint pain (p < 0,05).
TMJ effusion is associated with both disc displacement and joint pain: the effusion increased in direct proportion to the severity of pain and disc displacement. The possibility that there are various aetiologies for the condition should also be considered.
本研究旨在基于颞下颌关节紊乱病诊断标准（DC/TMD）评估关节内紊乱患者的颞下颌关节（TMJ）积液与关节痛之间的关系。
共评估了 120 例单侧疼痛关节患者（103 名女性和 17 名男性，平均年龄 29.9±12 岁）的 240 个 TMJ。根据 DC/TMD 指南进行临床评估。磁共振成像（MRI）用于评估每个关节的积液程度。对影像学和临床检查结果进行了统计学分析。
尽管结果表明中度关节积液与盘移位之间存在统计学显著关联（p<0.05），但中度积液与关节痛之间无统计学显著关联（p>0.05）。然而，明显的积液与盘移位和关节痛均有统计学显著关联（p<0.05）。
TMJ 积液与盘移位和关节痛均有关：积液随疼痛和盘移位的严重程度呈正比增加。还应考虑到存在多种病因的可能性。
