OBJECTIVE
This study aimed to evaluate the clinical and polysomnographic characteristics of sleep bruxism (SB) and delineate the determinant factors for temporomandibular disorders (TMD).
METHODS
Forty-six patients were allocated into the SB group (n = 26) and control group (n = 20). The signs and symptoms of TMD were recorded using the Research Diagnostic Criteria for TMD. Patients underwent a full-night polysomnographic recording and masseter and temporal muscle electromyographic recordings. Clinical and polysomnographic data in patients with SB were analyzed in relation to TMD.
RESULTS
The presence of TMJ sounds was significantly correlated with the number of bruxism bursts. Intra-articular pain in the TMJ was neither correlated with clinical nor polysomnographic parameters in patients with SB.
CONCLUSION
Lower sleep efficiency in patients with SB was caused by a higher number of bruxism episodes. Morning headaches were associated with the severity of SB during rapid eye movement sleep.
目的
本研究旨在评估睡眠磨牙症（SB）的临床和多导睡眠图特征，并确定其与颞下颌关节紊乱病（TMD）的相关因素。
方法
46 名患者被分为磨牙症组（n=26）和对照组（n=20）。使用研究性诊断标准（RDC/TMD）记录 TMD 的症状和体征。患者进行整夜多导睡眠图记录和咀嚼肌及颞肌肌电图记录。分析磨牙症患者的临床和多导睡眠图数据与 TMD 的关系。
结果
TMJ 弹响声的出现与磨牙症发作次数呈显著相关。TMJ 关节内疼痛与磨牙症患者的临床和多导睡眠图参数均无相关性。
结论
磨牙症患者的睡眠效率降低是由于磨牙症发作次数增加所致。快速眼动睡眠期的磨牙症严重程度与晨起头痛有关。
