O uso da toxina botulínica tipo A no controle do bruxismo: revisão de literatura.

Abstract

Botulinum toxin is a neurotoxin produced by the bacterium Clostridium botulinum, and its use provides a new alternative for the dental surgeon to control the symptoms of bruxism. Bruxism consists of a parafunctional habit of grinding or clenching your teeth, which can happen in two moments: during waking or sleeping, with varying degrees of intensity and persistence over time, it has no treatment because its etiology is unknown and because it is mediated by Central Nervous System. The objective of this work was to carry out a literature review on the use of botulinum toxin type A in the control of bruxism in order to determine its real effectiveness, in addition to describing its advantages and disadvantages. According to the reviewed studies, botulinum toxin was shown to be effective in relieving the symptoms of bruxism by promoting relaxation and relief in muscle tension, with no need for daily intervention by the patient. Despite the positive results, further in-depth studies should be carried out to consolidate the use of botulinum toxin as a routine alternative for the control of bruxism.
