Bruxism is an oral behavior that may lead to repetitive jaw-muscle activity characterized by clenching or grinding of the teeth and/or by bracing or thrusting of the mandible with 2 distinct circadian manifestations: sleep bruxism or awake bruxism. They share common risk factors and lead to similar consequences for the masticatory system but may have different etiology and pathophysiology. This oral behavior has been associated with tooth wear, masticatory muscle tenderness, headaches, and painful temporomandibular disorders. Available scientific evidence does not support the view that bruxism is a direct cause of pain, which should be taken into account when treating/managing patients.
磨牙症是一种可能导致重复性颌面部肌肉活动的口腔行为，其特征为牙齿紧咬或磨牙，和/或下颌支撑或前推，有两种不同的昼夜节律表现形式：睡眠磨牙症或清醒磨牙症。它们有共同的风险因素，对咀嚼系统会产生相似的后果，但病因和病理生理学可能不同。这种口腔行为与牙齿磨损、咀嚼肌压痛、头痛以及颞下颌关节疼痛性疾病有关。现有科学证据不支持磨牙症是疼痛直接原因的观点，在治疗/管理患者时应予以考虑。
