Bruximo do sono e disfunções temporomandibulares: revisão sistemática

Abstract

BACKGROUND AND OBJECTIVES: Epidemiologic studies of temporomandibular disorders (TMD) bring general understanding of the role of sleep bruxism (SP) as TMD triggering and/or perpetuating factor. To date, studies on this association have not shown conclusive results. A reason for the low specificity level of this association is the different diagnostic methodology, both for TMD and SB. This study aimed at evaluating the possible cause and effect ratio between SB and TMD. CONTENTS: Systematic literature review of research databases Medline, Cochrane, EMBASE, Pubmed, LILACS and BBO. Eligible criteria were papers published between January 2000 and August 2012, using the Research Diagnostic Criteria (RDC/TMD) for TMD diagnosis and polysomnography (PSG) for SB evaluation. Nine studies were selected by crossing chosen keywords. After applying inclusion criteria, four studies were selected. From five discarded studies, two were pilot studies, one was a review article, one case report and one comparative study not using RDC/TMD. CONCLUSION: Evaluated studies were unable to establish a positive relationship between SB and TMD when keywords sleep bruxism, temporomandibular disorders and polysomnography were crossed; however they reinforce the need for referring TMD patients with sleep disorders to polysomnographic evaluation.

Bruxism: An umbrella review of systematic reviews

“…Overall, three SR investigated prevalence rates among different populations, seventeen investigated associated factors, six evaluated effects on stomatognathic structures, two evaluated diagnostic accuracy of bruxism assessment tools, and thirteen assessed interventions' effectiveness . Statistical pooling of data using MA was available in 7 studies .…”

“…Statistical pooling of data using MA was available in 7 studies . Regarding language of publication, most reviews were published in English, one in German and one in Portuguese . All SR were published between 2007 and 2018.…”

“…Overall, nine SR were judged with low risk, seventeen with moderate risk and fifteen with high risk of bias . Major concerns regarding risk of bias were observed, which included the following: (a) lack of a priori registration of the study protocol; (b) inappropriate range of database/electronic sources searched; (c) no risk of bias assessment; (d) study selection, data collection or bias assessment performed by only one reviewer; (e) no publication bias assessment or sensitivity analysis; (f) high risk of bias in included primary studies.…”

<b>Bruxismo e sua relação com o Sistema Nervoso Central,/b>: Revisão de Literatura

“…CUNALI et al (6) afirmaram que, até o momento, as melhores ferramentas para o diagnóstico de bruxismo e DTM em pesquisa são, respectivamente, a polissonografia (PSG) e o índice Reseach Diagnostic Criteria (RDC/TMD). Como o diagnóstico clínico do bruxismo por meio da anamnese apresenta limitações, o ideal seria que todos os prováveis bruxômanos fossem submetidos ao exame de PSG.…”

“…Os sons produzidos pela fricção dos dentes normalmente são percebidos pelo companheiro. Entre os efeitos indesejáveis resultantes desse distúrbio estão: desgaste dos dentes, hipersensibilidade dentária a estímulos térmicos, dor orofacial e cefaleia temporal (2,6).…”
