The treatment of temporomandibular disorders (TMD) often includes the management of sleep bruxism (SB) and awake bruxism (AB). However, few studies have investigated how SB and AB change after the initiation of the interventions aimed at reducing the activity of masticatory muscles in TMD patients.
The aim of the present study was to investigate changes in self-reported SB and/or AB with regard to baseline at 6 weeks after receiving TMD treatment, i.e., counseling alone or counseling combined with any other treatment, and to investigate the association between the type of TMD treatment and changes in self-reported SB and/or AB.
A total of 68 TMD patients were included in this prospective study, and they all received counseling. Thirty-three of the 68 patients received additional treatment, e.g., physical therapy, psychological therapy and/or an oral appliance, beside counseling. The self-reported SB and AB frequency values were obtained from the Oral Behavior Checklist (OBC) questionnaire at baseline (t0) and at week 6 after receiving treatment (t1). The frequency of SB and AB was assessed as SB, AB-grinding, AB-clenching, AB-bracing, and AB-combined (i.e., the maximum frequency of all AB types combined). The Wilcoxon signed-rank test was used to compare the SB and AB frequency at t0 and t1 in patients who received counseling alone and those who received counseling combined with other treatment. The χ2 test was used to investigate the association between the type of TMD treatment and changes in SB and/or AB.
The frequency of self-reported SB and all types of AB did not change in patients who received counseling only. In contrast, there was a significant increase in the frequency of AB-bracing and AB-combined between t0 and t1 in patients who received counseling combined with other treatment.
No changes in the frequency of self-reported SB and all types of AB were found in patients who received counseling only. However, patients who received counseling combined with other treatment showed a significant increase in the frequency of AB-bracing and AB-combined as compared to baseline.
颞下颌关节紊乱（TMD）的治疗通常包括磨牙症（SB）和醒觉磨牙症（AB）的管理。然而，很少有研究调查 TMD 患者接受旨在减少咀嚼肌活动的干预措施后，SB 和 AB 如何变化。
本研究旨在调查接受 TMD 治疗后 6 周时，与基线相比，自我报告的 SB 和/或 AB 的变化，即仅接受咨询或咨询结合任何其他治疗，以及调查 TMD 治疗类型与自我报告的 SB 和/或 AB 的变化之间的关系。
本前瞻性研究共纳入 68 名 TMD 患者，所有患者均接受咨询。在 68 名患者中，有 33 名患者除了咨询外，还接受了物理治疗、心理治疗和/或口腔矫治器等额外治疗。在基线（t0）和接受治疗后 6 周（t1）时，使用口腔行为检查表（OBC）问卷获得自我报告的 SB 和 AB 频率值。SB 和 AB 的频率通过 SB、AB-磨牙、AB-紧咬、AB-支抗和 AB-联合（即所有 AB 类型中最大频率的组合）来评估。Wilcoxon 符号秩检验用于比较仅接受咨询的患者和接受咨询结合其他治疗的患者在 t0 和 t1 时的 SB 和 AB 频率。卡方检验用于调查 TMD 治疗类型与 SB 和/或 AB 变化之间的关系。
仅接受咨询的患者，自我报告的 SB 和所有类型 AB 的频率没有变化。相反，接受咨询结合其他治疗的患者，AB-支抗和 AB-联合的频率在 t0 和 t1 之间显著增加。
仅接受咨询的患者自我报告的 SB 和所有类型 AB 的频率没有变化。然而，与基线相比，接受咨询结合其他治疗的患者 AB-支抗和 AB-联合的频率显著增加。
