To evaluate the association between headache, myofascial temporomandibular disorder (TMD), and awake bruxism (AB).
Bruxism seems to act as a risk factor for TMD and its associated comorbidities, such as headaches.
In total, 406 medical records of individuals who sought care at a university dental clinic were screened. The Research Diagnostic Criteria for Temporomandibular Disorders was used to assess and diagnose TMD, as well as to obtain self-reports of AB and headache.
The sample consisted of 307 medical records. About 72.5% (221/305) of the sample reported having headaches, and 67.4% (180/267) and 68.4% (210/307) were diagnosed with AB and TMD, respectively. Individuals who reported having AB (odds ratio [OR], 2.28; 95% confidence interval [CI], 1.09-4.7) and who were diagnosed with myofascial TMD (OR, 2.53; 95% CI, 1.15-5.5) were more likely to have had headaches in the past 6 months when compared with patients without myofascial TMD and bruxism. Also, individuals who self-reported headache were 2.27 times (95% CI, 1.09-4.7) more likely to have AB and 2.45 times (95% CI, 1.13-5.34) more likely to have myofascial pain than individuals without headaches.
Individuals with myofascial TMD, headaches, or AB were more likely to have at least one of the other conditions.
评估头痛、肌筋膜颞下颌关节紊乱（TMD）和觉醒磨牙症（AB）之间的关联。
磨牙症似乎是 TMD 及其相关合并症（如头痛）的一个危险因素。
共筛选了 406 名在大学牙科诊所就诊的患者的病历。使用颞下颌关节紊乱的研究诊断标准来评估和诊断 TMD，以及获得 AB 和头痛的自我报告。
该样本由 307 份病历组成。约 72.5%（221/305）的样本报告有头痛，67.4%（180/267）和 68.4%（210/307）分别被诊断为 AB 和 TMD。报告有 AB（比值比 [OR]，2.28；95%置信区间 [CI]，1.09-4.7）和患有肌筋膜 TMD（OR，2.53；95% CI，1.15-5.5）的患者在过去 6 个月内发生头痛的可能性高于没有肌筋膜 TMD 和磨牙症的患者。此外，自我报告头痛的患者发生 AB 的可能性是没有头痛患者的 2.27 倍（95% CI，1.09-4.7），发生肌筋膜疼痛的可能性是没有头痛患者的 2.45 倍（95% CI，1.13-5.34）。
患有肌筋膜 TMD、头痛或 AB 的患者更有可能至少患有其他一种疾病。
