A toxina botulínica deve ser usada no tratamento do bruxismo do sono.

Abstract

Bruxism is characterized by a set of habits, teeth grinding and jaw clenching, during the contraction of masticatory muscles, having tooth wear as one of its major consequences. According to studies, there is no proof of effective treatments, although some interventions have been indicated, such as intramuscular Botulinum Toxin injection. The toxin is produced by a bacterium (Clostridium botulinum), and the injection consists in blocking the muscular contraction command arrival. The goal of this study was to review the literature regarding the applicability of the Botulinum Toxin to the treatment of sleeping bruxism, investigating if this drug should be indicated to the present parafunction through searches in Pubmed, Cochrane Library, Scielo, Google Scholar, and Medline databases, among articles published in dental magazines and journals. Due to the lack of high-quality scientific articles and the inconclusive results from the studies carried out up to the moment, the injection of Botulinum Toxin as an exclusive control for Sleep Bruxism is not recommended, once the toxin does not work on the genesis of sleep bruxism.
