The purpose of this study was to investigate whether the presence of concomitant widespread pain could influence the polysomnographic characteristics of patients with Sleep Bruxism(SB) and chronic masticatory muscle pain(TMD).
20 SB/TMD patients (17 women and 3 men) were evaluated according to the RDC/TMD questionnaire; and were divided into two groups according to the absence (Group A) or presence (Group B) of widespread pain. They were evaluated in a one night polysomnography paradigm.
Group B had lower sleep efficiency (p=0.034) and higher mean age (p=0.000) than Group A. Self-reported orofacial pain complaints, clinical and emotional aspects (RDC/TMD Axis I and II), and SB PSG parameters were similar in both groups; all patients had masticatory myofascial pain and the pain characteristics were bilateral location (95.0%) and tightness/pressure quality (70.0%).
At a single-night PSG, SB/TMD patients with widespread pain presented lower PSG sleep efficiency and higher mean age.
本研究旨在调查是否存在伴随的广泛性疼痛会影响磨牙症（SB）和慢性咀嚼肌疼痛（颞下颌关节紊乱病，TMD）患者的多导睡眠图特征。
根据RDC/TMD问卷对20名SB/TMD患者（17名女性和3名男性）进行评估；并根据是否存在广泛性疼痛分为两组（A组）无广泛性疼痛，（B组）有广泛性疼痛。对他们进行了一晚的多导睡眠图监测。
B组的睡眠效率低于A组（p = 0.034），平均年龄高于A组（p = 0.000）。两组患者自我报告的口面部疼痛主诉、临床和情绪方面（RDC/TMD轴I和轴II）以及SB多导睡眠图参数相似；所有患者均有咀嚼肌筋膜疼痛，疼痛特征为双侧部位（95.0%）和紧绷/压迫性质（70.0%）。
在一晚的多导睡眠图监测中，伴有广泛性疼痛的SB/TMD患者的多导睡眠图睡眠效率较低，平均年龄较高。
