Several studies have reported that sleep bruxism rarely occurs in isolation. Recently, in an epidemiological study of sleep bruxism and risk factors in the general population, it was found that among the associated sleep symptoms and disorders obstructive sleep apnea (OSA) was the highest risk factor for tooth grinding during sleep. The purpose of this report was to evaluate the effect of continuous positive airway pressure (CPAP) on sleep bruxism in a patient with both severe OSA and sleep tooth grinding. Two polysomnographic (PSG) recordings were carried out. The first showed 67 events of sounded tooth grinding, most of them appearing as an arousal response at the end of apnea/hypopnea events in both the supine and lateral postures. During the CPAP titration night most breathing abnormalities were eliminated and a complete eradication of the tooth grinding events was observed. The results of this study suggest that when sleep bruxism is related to apnea/hypopneas, the successful treatment of these breathing abnormalities may eliminate bruxism during sleep.
多项研究报告称，睡眠磨牙症很少单独出现。最近，在一项关于普通人群中睡眠磨牙症及其危险因素的流行病学研究中发现，在相关的睡眠症状和障碍中，阻塞性睡眠呼吸暂停（OSA）是睡眠时磨牙的最高风险因素。本报告的目的是评估持续气道正压通气（CPAP）对一名患有严重OSA和睡眠磨牙症患者的睡眠磨牙症的影响。进行了两次多导睡眠图（PSG）记录。第一次记录显示有67次有声音的磨牙事件，其中大多数表现为仰卧位和侧卧位时呼吸暂停/低通气事件结束时的觉醒反应。在CPAP滴定夜间，大多数呼吸异常被消除，并且观察到磨牙事件完全根除。本研究结果表明，当睡眠磨牙症与呼吸暂停/低通气相关时，成功治疗这些呼吸异常可能会消除睡眠时的磨牙症。
