OBJECTIVE: To investigate the prevalence of self-reported bruxism and its association with temporomandibular disorders (TMD). The hypothesis of the study was that self-reported bruxism is associated with TMD. METHODS: The data were gathered from 1962 subjects who participated in a field study in 2012-2013, including a questionnaire concerning bruxism and TMD symptoms as well as clinical sub-diagnoses of TMD using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Statistical method was chi-square test. Bonferroni correction was made, and a -value of <0.003 was considered as significant. RESULTS: The prevalence of self-reported bruxism was 39.6%: 34.0% in men and 44.5% in women. Those who reported sleep bruxism (SB) or awake bruxism (AB) had significantly more pain-related TMD symptoms and signs compared to those not reporting bruxism. CONCLUSION: The prevalence of self-reported bruxism is high among middle-aged adults and is associated with TMD pain-related symptoms and signs, as well as TMD diagnoses.
目的：调查自述磨牙症的流行情况及其与颞下颌关节紊乱病（TMD）的关系。本研究的假设是，自述磨牙症与 TMD 有关。
方法：本研究的数据来自于 1962 名 2012-2013 年参加现场研究的受试者，包括一份关于磨牙症和 TMD 症状的问卷，以及使用颞下颌关节紊乱病诊断标准（DC/TMD）进行的 TMD 临床亚诊断。统计方法为卡方检验。采用 Bonferroni 校正， -值<0.003 被认为有统计学意义。
结果：自述磨牙症的患病率为 39.6%：男性为 34.0%，女性为 44.5%。与不报告磨牙症的人相比，报告睡眠磨牙症（SB）或清醒磨牙症（AB）的人有更多的与疼痛相关的 TMD 症状和体征。
结论：自述磨牙症在中年人群中较为常见，与 TMD 的疼痛相关症状和体征以及 TMD 诊断有关。
