Prevalence of sleep bruxism in children: A systematic review

Abstract

INTRODUCTION: Prevalence of sleep bruxism (SB) in children is subject to discussions in the literature. OBJECTIVE: This study is a systematic literature review aiming to critically assess the prevalence of SB in children. METHODS: Survey using the following research databases: MEDLINE, Cochrane, EMBASE, PubMed, Lilacs and BBO, from January 2000 to February 2013, focusing on studies specifically assessing the prevalence of SB in children. RESULTS: After applying the inclusion criteria, four studies were retrieved. Among the selected articles, the prevalence rates of SB ranged from 5.9% to 49.6%, and these variations showed possible associations with the diagnostic criteria used for SB. CONCLUSION: There is a small number of studies with the primary objective of assessing SB in children. Additionally, there was a wide variation in the prevalence of SB in children. Thus, further, evidence-based studies with standardized and validated diagnostic criteria are necessary to assess the prevalence of SB in children more accurately.

Evaluation of the association of bruxism, psychosocial and sociodemographic factors in preschoolers

“…Indeed, tooth wear is the most common clinical consequence of sleep bruxism, 7 and is more severe in the primary dentition due to a lower degree of mineralization than in the permanent dentition. 27 However, the sole observation of surface wear on hard dental tissues does not confirm the clinical diagnosis of sleep bruxism, since this situation may be associated with other conditions.…”

“…7 A previous study found that this disorder was more prevalent among children from families with a better socioeconomic status. 11 Although this association has not yet been clarified, it may be related to the number of daily activities children perform, an issue that needs to be studied further.…”

“…The multifactor etiology involves factors influenced by the central nervous system and genetics, as well as psychosocial aspects. 7 Different methods are used to diagnose sleep bruxism, including the use of optical reading, the analysis of models, polysomnography, the assessment of masseter muscle contraction through bite strip electrodes, and self-reports/parental reports. 8,9 It is noteworthy that the American Academy of Sleep Medicine (AASM) considers the reports of parents/caregivers to be quite reliable 10 and sufficiently objective for use in epidemiological studies.…”

Use of common stimulants and awake bruxism – a survey study

“…Awake bruxism is defined as the clenching of teeth and jaws during wakefulness, in comparison to sleep bruxism, which characterized by unconscious clenching or grinding of teeth during sleep [7]. Prevalence of bruxism in general population is not accurately estimated and varies from 15% to 36% across the studies, depending on the diagnostic method [8][9][10][11]. It is worth noting that bruxism is significantly more prevalent in patients with temporomandibular disorders in comparison to healthy subjects [12,13].…”
