Bruxism is a common phenomenon, and emerging evidence suggests that biologic, psychologic, and exogenous factors have greater involvement than morphologic factors in its etiology. Diagnosis should adopt the grading system of possible, probable, and definite. In children, it could be a warning sign of certain psychologic disorders. The proposed mechanism for the bruxism-pain relationship at the individual level is that stress sensitivity and anxious personality traits may be responsible for bruxism activities that may lead to temporomandibular pain, which in turn is modulated by psychosocial factors. A multiple-P (plates, pep talk, psychology, pills) approach involving reversible treatments is recommended, and adult prosthodontic management should be based on a common-sense cautionary approach.
磨牙症是一种常见现象，新出现的证据表明，在其病因中，生物学、心理学和外部因素比形态学因素的影响更大。诊断应采用可能、很可能和确定的分级系统。在儿童中，它可能是某些心理障碍的警示信号。在个体层面上，磨牙症与疼痛关系的推测机制是，压力敏感性和焦虑人格特质可能导致磨牙行为，进而引发颞下颌疼痛，而这反过来又受到社会心理因素的调节。建议采用包括可逆性治疗的多P（牙合板、鼓励性谈话、心理学、药物）方法，成人修复治疗管理应基于常识性的谨慎方法。
