Sleep bruxism

Sleep bruxism (SB) is an activity characterized by teeth grinding or clenching. SB can have different dental and orofacial consequences. While in otherwise healthy individuals it is considered a behavior, when it is associated to sleep or neurological disorders and/or presenting harmful consequences it is categorized as a disorder. SB etiology and mechanisms are multifactorial. The diagnosis of SB is based on self-report (possible), clinical examination (probable) and electromyographic for disorder suspected cases (definitive). The management of SB is multimodal and based on a multidisciplinary approach. The identification of phenotypes will be essential in the next future.
