PSYCHOSOCIAL STRESS, BRUXISM, AND MYOFASCIAL TMD

描述：这项研究将考察压力、痛苦和 TMD肌筋膜疼痛加重中的磨牙症。它还将评估 磨牙症在调节常用口腔药物疗效中的作用 家用电器。这项研究将招募85名新入院的TMD诊所在 大学。新泽西州医学和牙科学会(UMDNJ) 肌筋膜TMD的诊断标准及既往无治疗史 有治疗面部疼痛的口腔用具。一组85名对照受试者 没有任何TMD的人也将从UMDNJ的非TMD诊所招募。 测试压力、痛苦和磨牙症在面部恶化中的作用 疼痛、TMD患者和对照组将完成每日的压力日记， 一周的痛苦和痛苦。在这个时期的开始，恰好是一个 一周后，将进行全口牙印。这些印象 将用于准备将在扫描下进行检查的显微照片 电子显微镜。通过检查两者之间划痕的变化 期间，受试者将根据磨牙症的严重程度进行分级。回归模型 将测试压力、痛苦、磨牙症和面部疼痛之间的关系。 分析还将比较TMD患者和对照组磨牙症的严重程度。 为了测试磨牙症在治疗结果中的作用，TMD患者将接受 随机分配接受全覆盖硬亚克力夹板或 腭部夹板。在接下来的一个月里的两次随访中，疼痛和 将对残疾进行评估。分析将检查是否有效 主动型与腭型夹板之间的关系受患者的程度影响 展示磨牙症的证据。

DESCRIPTION: This study will examine the role of stress, distress and bruxism in pain exacerbation in myofascial TMD. It will also evaluate the role of bruxism in moderating the efficacy of a commonly used oral appliance. The study will recruit 85 new admissions to the TMD clinic at the Univ. of Medicine and Dentistry of New Jersey (UMDNJ) who meet diagnostic criteria for myofascial TMD and who have had no prior treatment with oral appliances for facial pain. A group of 85 control subjects without any TMD will also be recruited from the non-TMD clinics at UMDNJ. To test the role of stress, distress, and bruxism in exacerbating facial pain, TMD patients and controls will complete daily diaries of stress, distress and pain for one week. At beginning of this period and exactly one week later, full-mouth dental impressions will be taken. These impressions will be used to prepare micrographs that will be examined under a scanning electron microscope. By examining changes in scratch marks between the two periods, subjects will be graded for severity of bruxism. Regression models will test the relation between stress, distress, bruxism, and facial pain. Analyses will also compare severity in bruxism in TMD patients and controls. To test the role of bruxism in treatment outcome, TMD patients will then be randomly assigned to receive either a full-coverage hard acrylic splint or palatal splint. In two followup visits over the following month, pain and disability will be assessed. Analyses will examine whether the efficacy of the active vs. palatal splint is moderated by the degree to which patients show evidence of bruxism.
