Bruxismo: da etiologia ao diagnóstico

Abstract

Bruxism is a significant clinical phenomenon, considered the most damaging amongst all the parafunctions of the stomatognathic system. It is the source of multiple dental injuries. In 2005, the Academy of Prosthodontics defined bruxism as a non-functional act; an involuntary oral habit, consisting in the rhythmic or spasmodic grinding, grating or clenching of the teeth, in non-functional movements of the mandible, which could lead to the development of an occlusal trauma. The American Academy of Sleep Medicine (ex-American Sleep Disorders Association) (AASM) classified the SB as a parasomnia of the sleep: “a disturbance of the sleep that does not constitute an abnormality of the processes responsible for sleeping and for the state of vigilance in itself, being instead an undesirable phenomenon that takes place during sleep”. In 2013, Lobbezzo and their collaborators, defined bruxism as: a repetitive muscular activity of the mandible, characterized by the clenching or grinding of the teeth and / or by “bracing” or pushing the mandible. Bruxism has two distinctive circadian manifestations: it can occur during sleep (bruxism of the sleep) or during vigilance (awakened bruxism). Currently, the most plausible explanation for the etiopathogeny of bruxism is based on a multifactorial model, in which both psychosocial and physiopathological factors interact with peripheral morphological stimuli. The evaluation and diagnosis of SB is often a true challenge. In general, the evaluation is based on the reports of sounds of the teeth grinding during sleep, and on the presence of clinical signs and symptoms. However, only an EMG recording of the chewing muscles can confirm the diagnosis. Various portable tools of diagnostic were developed to record the EMG activity of the temporal and of the masseter during sleep, in order to avoid the use of more sophisticated but highly expensive and slow polissonography.

O bruxismo é um fenómeno clinico significante, sendo também considerado a mais prejudicial, entre todas as parafunções do sistema estomatognático, causando lesões dentárias. A Academy of Prosthodontics, em 2005, definiu bruxismo como o acto não funcional, um hábito oral involuntário, que consiste no rítmico ou espasmódico ranger, cerrar e apertar dos dentes, em movimentos da mandibula não funcionais, o que pode levar ao desenvolvimento de trauma oclusal. A American Academy of Sleep Medicine (antiga American Sleep Disorders Association) (AASM) classificou o SB como uma parasomnia do sono: “um distúrbio do sono que não é uma anormalidade dos processos responsáveis pelo sono e estado de vigília em si, mas sim um indesejável fenómeno que ocorre durante o sono”. Em 2013, Lobbezoo e colaboradores, definiram o bruxismo da seguinte forma: O bruxismo é uma atividade muscular da mandíbula de forma repetitiva caracterizada por apertar ou ranger dos dentes e / ou por “bracing” ou empurrar da mandíbula. Bruxismo tem duas manifestações circadianas distintas: pode ocorrer durante o sono (indicado como bruxismo do sono) ou durante a vigília (indicado como bruxismo acordado). Atualmente, a explicação mais plausível sobre a etiopatogenia do bruxismo assenta num modelo multifatorial, no qual fatores psicossociais e fatores fisiopatológicos interagem com estímulos morfológicos periféricos. A avaliação e diagnóstico da SB é muitas vezes um verdadeiro desafio. Em geral, a avaliação é baseada em relatos de sons de trituração dos dentes durante o sono e a presença de sinais e sintomas clínicos. No entanto, apenas uma gravação de EMG dos músculos mastigatórios pode confirmar o diagnóstico SB. Várias ferramentas de diagnóstico portáteis foram desenvolvidas para gravar a atividade EMG do temporal e do masséter durante o sono, para evitar o uso da mais sofisticada mas altamente dispendiosa e demorada polissonografia.
