MORAIS, Dayana Campanelli; OLIVEIRA, Aleli Tôrres de; MONTEIRO, André Antonio  e  ALENCAR, Maria José Santos. Bruxism and its relationship with the central nervous system: Literature Review. Rev. Bras. Odontol. [online]. 2015, vol.72, n.1-2, pp. 62-65. ISSN 1984-3747.

Bruxism is described as an orofacial movement called parafunction, whose etiology is complex and multifactorial. This study aimed to facilitate the understanding of the possible causes of this disorder and its relation with the central nervous system, through a literature review. Some authors ^4,23,19 affirm the hypothesis of bruxism be mediated centrally, making the emotional stress and anxiety important factors for its appearance. For diagnosis, polysomnography (PSG) is an important tool, however due it’s onerous cost, few studies were found correlating the PSG and bruxism, which is a matter of great importance that more research be conducted on the subject.
