Prevalence of sleep bruxism in children: a systematic review

Eduardo Machado et al. Dental Press J Orthod. 2014 Nov-Dec.

Abstract
in English, Portuguese

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.

INTRODUÇÃO:: a prevalência de bruxismo do sono (BS) na população infantil é tema de discussões na literatura.

OBJETIVO:: assim, este trabalho, por meio de uma revisão sistemática, teve como objetivo avaliar, de forma crítica, a prevalência de BS em crianças.

MÉTODOS:: foi feito um levantamento nas bases de pesquisa MEDLINE, Cochrane, Embase, PubMed, Lilacs e BBO, entre os anos de 2000 e fevereiro de 2013, com enfoque em estudos que avaliaram especificamente a prevalência de BS em crianças.

RESULTADOS:: após a aplicação dos critérios de inclusão, chegou-se a quatro estudos. Entre os artigos selecionados, as taxas de prevalência de BS variaram de 5,9% a 49,6%, sendo que essas variações apresentaram possíveis associações com os critérios diagnósticos para BS.

CONCLUSÃO:: verifica-se um número reduzido de estudos que apresentaram o objetivo primário de avaliar o BS em crianças, além de uma grande variação nas taxas de prevalência. Torna-se necessária a realização de novos estudos, baseados em métodos de evidências e com critérios diagnósticos padronizados e validados, para avaliar com maior precisão a prevalência do BS em crianças.
