A brief description of bruxism, in order not to waste time on data common to most colleagues and for personal culture for non-experts, is sufficient to deepen the topic on  [[wikipedia:Bruxism#cite_ref-Wassell_2008_1-0|Wikipedia]] which, obviously, will not be exhaustive for our purposes. Let's start, therefore, by asking ourselves some specific questions: Is bruxism an oral parafunctional activity,<ref name="Wassell 20082">Wassell R, Naru A, Steele J, Nohl F (2008). ''Applied occlusion''. London: Quintessence. pp. 26–30. ISBN <bdi>9781850970989</bdi>.</ref> that is, is it not physiologically related to normal function such as eating or speaking? Is bruxism a common behavior despite reports of prevalence ranging from 8% to 31% in the general population?<ref>Manfredini D, Winocur E, Guarda-Nardini L, Paesani D, Lobbezoo F (2013). "Epidemiology of bruxism in adults: a systematic review of the literature". ''Journal of Orofacial Pain''.
