A systematic review of etiological and risk factors associated with bruxism

Abstract

There is convincing evidence that (sleep-related) bruxism can be induced by esophageal acidification and also that it has an important relationship with smoking in a dose-dependent manner. Disturbances in the central dopaminergic system are also implicated in the etiology of bruxism.

Association of temporomandibular disorder pain with awake and sleep bruxism in adults

“…While persons with awake bruxism are directly aware of their condition, persons with sleep bruxism will naturally require symptoms upon waking up or information from their partners to gain such awareness. It is also useful from an etiological point of view to distinguish between awake and sleep bruxism, as both may differ in terms of risk factors and genesis [9,24]. Sleep bruxism is part of a sleep disorder and is more influenced by behavioral factors such as smoking or coffee/alcohol use [9,16], whereas awake bruxism is more likely associated with psychosocial factors such as stress and coping [24].…”

Depending on diagnostic criteria and definitions, prevalence figures for bruxism have been reported to range from 8 to 31.4% and decrease with age [27].…”

“…Das Risiko für CMD-Schmerzen unterschied sich nur unwesentlich für die separate Angabe von Wach-(OR 1,7; KI 1,0-2,7) oder Schlafbruxismus (OR 1,8; KI 1,4-2,4). Hingegen stieg das Risiko wesentlich bei gleichzeitigem Vorliegen von 7; KI 5,[4][5][6][7][8][9][10][11]1). …”

Relação entre apneia obstrutiva do sono e bruxismo do sono: revisão de literatura

“…-e algumas comorbidades acidificação esofágica e AOS, por exemplo) [17][18][19][20][21][22][23] . Segundo informações da AASM, o BS pode ocorrer em qualquer estágio do sono, mas é prevalente no estágio 2.…”

Efeito de três intervenções de fisioterapia comparadas a tratamento odontológico em indivíduos com bruxismo: um ensaio clínico randomizado

“…[4,64] Esta dor muscular transitória induzida pela AMRM relacionada ao bruxismo ou contrações musculares excessivas, pode levar à rupturas das fibras musculares e tecidos adjacentes, podendo ser desenvolvida em poucas horas e diminuir gradualmente; apesar da sua característica persistente, que pode prolongar por longos anos. [4,20,51,61,65] Anteriormente, a dor resultante do bruxismo podia ser explicada pela teoria do ciclo vicioso, em que um fator inicial como movimento anormal e estresse que resulta em dor, levaria à hiperatividade muscular. Esta, levaria ao espasmo e fadiga e, consequentemente, a mais dor, com perpetuação do ciclo.…”
