Simple snoring is defined as the production of sound in the upper aerodigestive tract during sleep, not accompanied by other pathologies. Sleep bruxism (SB) refers to repetitive phasic, tonic, or mixed masticatory muscle activity during sleep. In this study, we investigated the relationship between simple snoring and SB in patients without obstructive sleep apnea (OSA). A total of 565 snoring subjects underwent polysomnography. After examination, individuals with OSA were excluded from the study group. Finally, 129 individuals were analyzed. The bruxism episode index was positively correlated with maximum snore intensity. Phasic bruxism was positively correlated with snore intensity in all sleep positions. Bruxers had a significantly decreased average and minimum heart rate compared with non-bruxers. Supine sleep position seemed to have a significant impact on snore intensity and SB. In summary, our study showed the relationship between SB, snore intensity, and body position. Phasic bruxism was positively correlated with snore intensity despite the body position, which is an interesting and novel finding.
单纯打鼾被定义为睡眠期间上气道消化道发出的声音，不伴有其他病理状况。睡眠磨牙症（SB）是指睡眠期间重复性的阶段性、强直性或混合性咀嚼肌活动。在本研究中，我们调查了无阻塞性睡眠呼吸暂停（OSA）患者中单纯打鼾与SB之间的关系。共有565名打鼾受试者接受了多导睡眠图检查。检查后，患有OSA的个体被排除在研究组之外。最终，对129名个体进行了分析。磨牙症发作指数与最大打鼾强度呈正相关。在所有睡眠姿势下，阶段性磨牙症与打鼾强度呈正相关。与非磨牙者相比，磨牙者的平均心率和最低心率显著降低。仰卧睡眠姿势似乎对打鼾强度和SB有显著影响。总之，我们的研究显示了SB、打鼾强度和体位之间的关系。尽管体位不同，阶段性磨牙症与打鼾强度仍呈正相关，这是一个有趣且新颖的发现。
