Sleep bruxism (SB) is a common phenomenon defined as a masticatory muscle activity during sleep. Untreated severe SB can have significant dental and orofacial consequences. SB has often been linked with stress and maladaptive coping strategies. Therefore, in this study, a potential correlation between SB, perceived stress and coping strategies was evaluated. A total of 60 adults were enrolled into this study. Participants underwent a detailed intra- and extraoral exam focused on detecting bruxism symptoms. Additionally, the overnight Bruxism Index was recorded using the Bruxoff device. A total of 35 participants with symptoms of bruxism were assigned to the study group, whereas 25 asymptomatic participants were assigned to the control group. The Perceived Stress Scale (PSS-10) was used for stress assessment and Brief-COPE for coping strategies. Results showed that the higher the PSS-10 score, the higher the Bruxism Index was in the study group. Positive coping strategies were chosen most frequently in the control group, while maladaptive ones were chosen in the study group. It can be concluded that there is a relationship between perceived stress and sleep bruxism. Moreover, the type of coping strategies used by participants may have an impact on sleep bruxism, but the relationship should be further investigated.
睡眠磨牙症（SB）是一种常见的现象，定义为睡眠期间咀嚼肌的活动。未经治疗的严重 SB 会对牙齿和口腔颌面部产生重大影响。SB 通常与压力和适应不良的应对策略有关。因此，在这项研究中，评估了 SB、感知压力和应对策略之间的潜在相关性。共有 60 名成年人参与了这项研究。参与者接受了详细的口腔内和口腔外检查，重点是检测磨牙症症状。此外，使用 Bruxoff 设备记录了整夜磨牙指数。共有 35 名有磨牙症状的参与者被分配到研究组，而 25 名无症状的参与者被分配到对照组。使用感知压力量表（PSS-10）评估压力，使用Brief-COPE 评估应对策略。结果表明，研究组中 PSS-10 评分越高，磨牙指数越高。对照组中最常选择积极的应对策略，而研究组中则选择适应不良的应对策略。可以得出结论，感知压力与睡眠磨牙症之间存在关系。此外，参与者使用的应对策略类型可能对睡眠磨牙症有影响，但这种关系需要进一步研究。
