Nocturnal bruxing events were recorded during a single night of sleep for 12 subjects with sleep-disordered breathing and 12 age- and sex-matched controls. The results suggest that bruxing events are very common in both groups and are closely associated with sleep arousals. There were few differences in the number, duration, or type of bruxing events between these two groups. Bruxing events were common during stage 1, stage 2, and REM sleep, while they rarely occurred during stage 3 and 4 sleep. The average duration of bruxing events ranged from 3.82 to 6.68 seconds. There was a trend toward more bruxing events occurring while sleeping on the back than on the side.
在一个夜间睡眠期间，记录了12名患有睡眠呼吸障碍的受试者以及12名年龄和性别匹配的对照组的夜间磨牙事件。结果表明，磨牙事件在两组中都非常常见，并且与睡眠觉醒密切相关。这两组在磨牙事件的数量、持续时间或类型方面几乎没有差异。磨牙事件在睡眠第1阶段、第2阶段和快速眼动睡眠期间很常见，而在第3阶段和第4阶段睡眠期间很少发生。磨牙事件的平均持续时间为3.82至6.68秒。仰卧睡眠时比侧卧睡眠时发生更多磨牙事件的趋势。
