To evaluate the association between definitive sleep bruxism and primary headaches and to analyze other variables that may also be associated with definitive sleep bruxism. A descriptive study was carried out with a sample of adults with a medical indication for polysomnography in Florianópolis, Brazil. Data were collected in three phases: questionnaires, physical examinations and polysomnography. Pearson's chi-square test and unadjusted and adjusted binary regressions were carried out using the Statistical Package for the Social Sciences computer program. The significance level was 5%, and the confidence interval (CI) was 95%. The test power was calculated by the G*Power computer program. The sample consisted of 23 men and 19 women, with an average age of 45.6 ± 15 years. Approximately 76% of the participants had sleep bruxism, and 57% had primary headache. The odds ratio between definitive sleep bruxism and primary headaches was 0.86 (95% CI 0.20 to 3.64; = 0.71), demonstrating no association between these variables. Among the other variables analyzed, only alcohol consumption was associated with bruxism, with an odds ratio of 5.96 (95% CI 1.26 to 28.28; = 0.03). According to binary regression, no variable was a confounding factor for definitive sleep bruxism. The power of the test was 0.028. There was no association between definitive sleep bruxism and primary headaches. Alcohol consumption increases the patient's chance of having sleep bruxism by almost six times. Knowledge about the association of sleep bruxism with other variables can help dentists detect it and explain the condition to patients.
评估确诊的睡眠磨牙症与原发性头痛之间的关联，并分析其他可能也与确诊的睡眠磨牙症相关的变量。在巴西弗洛里亚诺波利斯对有进行多导睡眠图检查医学指征的成年人样本进行了一项描述性研究。数据收集分三个阶段进行：问卷调查、体格检查和多导睡眠图检查。使用社会科学统计软件包计算机程序进行了Pearson卡方检验以及未调整和调整后的二元回归分析。显著性水平为5%，置信区间（CI）为95%。检验效能由G*Power计算机程序计算得出。样本包括23名男性和19名女性，平均年龄为45.6±15岁。约76%的参与者有睡眠磨牙症，57%有原发性头痛。确诊的睡眠磨牙症与原发性头痛之间的比值比为0.86（95%CI 0.20至3.64；P=0.71），表明这些变量之间无关联。在分析的其他变量中，只有饮酒与磨牙症相关，比值比为5.96（95%CI 1.26至28.28；P=0.03）。根据二元回归分析，没有变量是确诊的睡眠磨牙症的混杂因素。检验效能为0.028。确诊的睡眠磨牙症与原发性头痛之间无关联。饮酒使患者患睡眠磨牙症的几率增加近六倍。了解睡眠磨牙症与其他变量的关联有助于牙医检测到它并向患者解释病情。
