Abstract

Bruxism is a movement disorder characterized by grinding and clenching of teeth. Polysomnography and controlled sleep studies have allowed us to better understand the relationship between sleep stages, micro-arousal responses, and autonomic function and bruxism. Bruxism can sometimes threaten the integrity of the masticatory system when the magnitude and direction of the applied force exceeds the system's adaptive capacity. Thus, bruxism is the most common contributing factor found in patients with temporomandibular disorder and orofacial pain. In addition, it contributes to abnormal wear of teeth, periodontal disease, and causes considerable problems in dental care. There are two main types of bruxism, which are associated with various circadian cycles (sleep and wake bruxism) that may differ in pathophysiology. Bruxism is considered to have multifactorial etiology. Sleep bruxism have been associated with peripheral factors, psychosocial influences such as psychological distress or anxiety, and central pathophysiology involving brain neurotransmitters. Currently, there is no specific and effective treatment that can permanently get rid of the bruxism. Palliative treatment and alternatives have been mainly proposed to prevent the pathological effects of bruxism on the oral and maxillofacial system and to ameliorate adverse clinical outcomes. This study is a review of literature published in the last 30 years on 'bruxism', especially sleep bruxism, and is performed using Medical Subject Headings (MeSH) Database and PubMed search engi
