To provide a scoping review of the literature by assessing all the English-language papers that investigated the relationship between sleep bruxism (SB) and temporomandibular disorders (TMDs).
A search was performed in the National Library of Medicine (PubMed) and Scopus databases, in order to identify all the articles published assessing the relationship between SB and TMDs, by several different approaches. The selected articles were then structurally read and summarized in PICO tables. The articles were selected independently by the two authors.
Out of 185 references that were initially retrieved, 47 articles met the inclusion criteria and were thus included in the review. The studies were divided into four categories based on the type of SB assessment: 1. questionnaire/self-report (n = 26), 2. clinical examination (n = 7), 3. electromyography (EMG) (n = 5), and 4. polysomnography (PSG) (n = 9).
Studies based on questionnaire/self-report SB featured a low specificity for SB assessment, and in general they found a positive association with TMD pain. On the contrary, instrumental studies (i.e., electromyography, polysomnography) found a lower level of association or even a negative relationship between SB and TMD pain. Findings from this updated review confirmed the conclusions of a previous review by Manfredini & Lobbezoo, suggesting that literature findings on the relationship between SB and TMDs are dependent on the assessment strategies that are adopted for SB. Future studies should consider SB as a multifaceted motor behavior that must be evaluated in its continuum spectrum, rather than using a simplified dichotomous approach of presence/absence.
通过评估所有调查磨牙症（SB）与颞下颌关节紊乱病（TMD）之间关系的英文文献，对该领域文献进行综述。
在国家医学图书馆（PubMed）和 Scopus 数据库中进行检索，以确定所有评估 SB 与 TMD 之间关系的文章，这些文章采用了多种不同的方法。然后，对选定的文章进行结构性阅读，并在 PICO 表中进行总结。这两位作者独立选择文章。
最初检索到的 185 篇参考文献中，有 47 篇符合纳入标准，并被纳入综述。这些研究根据 SB 评估类型分为以下四类：1. 问卷调查/自我报告（n=26）；2. 临床检查（n=7）；3. 肌电图（EMG）（n=5）；4. 多导睡眠图（PSG）（n=9）。
基于问卷/自我报告的 SB 研究对 SB 评估的特异性较低，总体上发现与 TMD 疼痛呈正相关。相反，仪器研究（即肌电图、多导睡眠图）发现 SB 与 TMD 疼痛之间的关联程度较低，甚至存在负相关。本综述更新后的研究结果证实了 Manfredini 和 Lobbezoo 之前的综述结论，表明关于 SB 与 TMD 之间关系的文献结果取决于用于 SB 的评估策略。未来的研究应将 SB 视为一种多方面的运动行为，必须在其连续谱中进行评估，而不是采用简单的存在/不存在的二分法方法。
