Bruxism is a sleep related disorder. Studies show that bruxism is centrally mediated disorder and psychosocial factors like stress have little role in the etiology of bruxism. There are no reliable methods for assessing bruxism in the clinic which have reasonable diagnostic validity. Tooth wear is considered analogous to bruxism but it can also be the result of attrition, abrasion and erosion. Devices such as miniature self contained EMG detector analyzer have potential if they are scientifically verified in large population and proven to be useful in clinics in terms of easy use. In the absence of definitive evidence, bruxism can be best managed by occlusal appliances, counseling, change in lifestyle and pharmacological interventions.
