To investigate the association between probable sleep bruxism (PSB) and associated factors in schoolchildren.
A case-control study was conducted with a representative sample of 320 schoolchildren aged 8 to 10 years. The case group (160 children with PSB) and the control group (160 children without PSB) were matched for sex and age at a proportion of 1:1. Information on audible characteristics of PSB, harmful oral habits, and socio-demographic characteristics as collected through questionnaires answered by the parents/caregivers. The family functioning of children was measured through The Family Adaptability and Cohesion Evaluation Scales (FACES III). Mothers self-administered the Lipp Stress Symptoms Inventory (LSSI) for adults to measure mothers' stress and the children filled out the Child Stress Scale (CSS) to measure the children stress. Data analysis used descriptive and logistic regression analyses (p < 0.05).
Among the children with stress, 67.3% had PSB. Children with stress (OR = 2.22, 95% CI 1.18-4.19), those with a history of nail biting (OR = 2.22, 95% CI 1.39-3.55), and biting objects (OR = 1.77, 95% CI 1.09-2.87) were more likely to have PSB.
Childhood stress and a history of nail biting or biting objects are important signs to be considered in schoolchildren with PBS.
These results alert that the PBS might be a sign of stress and other psychological problems such as tension and anxiety related to the presence of harmful oral habits. Furthermore, the results could help in the targeting of anamnesis, improved prevention and treatment strategies for sleep bruxism which should involve an interdisciplinary approach.
研究儿童中可能发生的磨牙症（PSB）与相关因素之间的关联。
采用病例对照研究方法，对 320 名 8 至 10 岁的学龄儿童进行了代表性抽样。病例组（160 名患有 PSB 的儿童）和对照组（160 名无 PSB 的儿童）按性别和年龄以 1:1 的比例进行匹配。通过父母/照顾者回答的问卷收集有关 PSB 的可听见特征、有害口腔习惯和社会人口统计学特征的信息。通过家庭适应性和凝聚力评估量表（FACES III）测量儿童的家庭功能。母亲通过 Lipp 压力症状量表（LSSI）为成人测量母亲的压力，孩子通过儿童压力量表（CSS）测量孩子的压力。数据分析采用描述性和逻辑回归分析（p < 0.05）。
在有压力的儿童中，有 67.3％患有 PSB。有压力的儿童（OR = 2.22，95％CI 1.18-4.19），有咬指甲史的儿童（OR = 2.22，95％CI 1.39-3.55）和咬物史的儿童（OR = 1.77，95％CI 1.09-2.87）更有可能患有 PSB。
儿童期压力以及咬指甲或咬物的病史是患有 PBS 的儿童要考虑的重要迹象。
这些结果表明，PSB 可能是压力的迹象，以及与有害口腔习惯有关的紧张和焦虑等其他心理问题的迹象。此外，这些结果可以帮助进行病史查询，改善针对磨牙症的预防和治疗策略，这些策略应涉及跨学科方法。
