Sleep bruxism (SB) is a behavior of central origin that is related to different factors. This systematic review aimed to determine the prevalence of clinical signs and symptoms of the masticatory system and their association in children with SB. A structured search in ten databases were taken. Two authors independently selected studies, extracted the data, study quality assessment and graded the evidence. A meta-analysis of proportion and association was performed under random-effect model, confidence interval of 95% and p < 0.05 for pulled values. Were included 22 studies, and their overall quality was poor. The more common clinical signs and symptoms of the masticatory system in children with SB were primary canine wear (P:84.13, 95% CI:78.13-89.32; p = 0.248; I 25.05), dental wear (P:73.76, 95% CI:38.73-96.91; p < 0.001; I 97.62) and headache (P:52.85, 95% CI:38.92-66.56; p < 0.001; I 93.65). The prevalence of SB in children was 31.16% (P:31.16, 95% CI:22.18-40.92; p < 0.001; I 98.56). There was no significant risk of dental wear and headache in children with SB. There is low to very low certainty of the evidence. The more prevalent clinical signs and symptoms of the masticatory system presented in children with SB were primary canine wear, dental wear and headache. Further studies of high quality are still needed to elucidate these important questions.
磨牙症（SB）是一种源于中枢的行为，与多种因素有关。本系统综述旨在确定儿童磨牙症的咀嚼系统临床体征和症状的流行情况及其相关性。在十个数据库中进行了结构化搜索。两名作者独立选择研究、提取数据、评估研究质量并对证据进行分级。采用随机效应模型进行比例和关联的荟萃分析，置信区间为 95%，p 值<0.05。共纳入 22 项研究，整体质量较差。磨牙症儿童更常见的咀嚼系统临床体征和症状为：首发恒尖牙磨损（P：84.13，95%CI：78.13-89.32；p=0.248；I 2 =5.05%）、牙齿磨损（P：73.76，95%CI：38.73-96.91；p<0.001；I 2 =97.62%）和头痛（P：52.85，95%CI：38.92-66.56；p<0.001；I 2 =93.65%）。磨牙症儿童的患病率为 31.16%（P：31.16，95%CI：22.18-40.92；p<0.001；I 2 =98.56%）。磨牙症儿童的牙齿磨损和头痛风险无显著差异。证据的确定性为低到极低。磨牙症儿童更常见的咀嚼系统临床体征和症状为首发恒尖牙磨损、牙齿磨损和头痛。仍需要高质量的进一步研究来阐明这些重要问题。
