The aim of the present systematic review was to answer the overall research question: "To what extent is bruxism associated with musculoskeletal signs and symptoms?". The review was performed in accordance with the PRISMA guidelines. A PubMed search of articles published until 23 November 2017 was conducted. The search string included both MeSH terms and text words. Results were presented in categories according to study design, study population (eg, adults, children), bruxism sub-type (awake, sleep), assessment methods for bruxism and musculoskeletal symptoms (self-report, validated test) and type of outcome (pain, non-painful musculoskeletal symptoms). It could be concluded that bruxism is to some extent associated with musculoskeletal symptoms, even though the evidence is conflicting and seems to be dependent on many factors, such as age, whether the bruxism occurs during sleep or wakefulness, and also the quality of the diagnostic methodology regarding bruxism and musculoskeletal signs and symptoms. The literature does not support a direct linear causal relationship between bruxism and such symptoms, but points more in the direction of a multifaceted relationship dependent on the presence of other risk factors. Pain is by far the most commonly assessed symptom, whereas non-painful musculoskeletal symptoms have generally not been systematically evaluated. In the light of recent findings indicating that non-painful symptoms may precede TMD pain, it is suggested to increase the scientific focus on non-painful musculoskeletal symptoms in future studies. Also, future studies should use validated methods for case definition and outcome assessments.
“磨牙症与肌肉骨骼体征和症状有多大程度的关联？”。该评价是按照 PRISMA 指南进行的。对截至 2017 年 11 月 23 日发表的文章进行了 PubMed 检索。检索词包括 MeSH 术语和文本词。结果根据研究设计、研究人群（例如，成年人、儿童）、磨牙症亚型（清醒时、睡眠时）、磨牙症和肌肉骨骼症状的评估方法（自我报告、验证性测试）和结果类型（疼痛、非疼痛性肌肉骨骼症状）进行分类呈现。可以得出结论，磨牙症在某种程度上与肌肉骨骼症状有关，尽管证据相互矛盾，似乎取决于许多因素，如年龄、磨牙症是发生在睡眠时还是清醒时，以及磨牙症和肌肉骨骼体征和症状的诊断方法的质量。文献并不支持磨牙症与这些症状之间存在直接的线性因果关系，而是更多地指向依赖其他危险因素的多方面关系。疼痛是迄今为止最常评估的症状，而非疼痛性肌肉骨骼症状通常未得到系统评估。鉴于最近的研究结果表明非疼痛性症状可能先于 TMD 疼痛出现，建议在未来的研究中增加对非疼痛性肌肉骨骼症状的科学关注。此外，未来的研究应使用验证过的方法来定义病例和评估结果。
