Prevalence of Bruxism in alcohol abusers: a systematic review conducted according to PRISMA guidelines and the cochrane handbook fo

Abstract

Background Bruxism, a common oral parafunctional behavior characterized by the grinding or clenching of teeth,is a multifactorial condition with potentially detrimental effects on oral health and overall well-being. In recent years,there has been growing interest in understanding the relationship between bruxism and alcohol abuse, as bothare prevalent issues that may share underlying factors and exacerbate each other. This systematic review, followingthe Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, aims to evaluate thefrequency of bruxism among individuals with alcohol abuse. Methods A comprehensive search of electronic databases, including PubMed, Lilacs, Scopus and Web of Science,will be conducted to identify relevant studies published up to the knowledge cutoff date in January 2023. The searchstrategy will include keywords related to bruxism, alcohol abuse, and their synonyms. Inclusion criteria will encompassoriginal research studies, such as observational, cross-sectional, cohort, and case-control studies, as well as clinicaltrials, that examine the relationship between bruxism and alcohol abuse. Two independent reviewers will perform thestudy selection, data extraction, and quality assessment, with discrepancies resolved by consensus. Results The systematic review will present a summary of the identified studies, including the study design, characteristics of the study populations, and key findings related to the association between bruxism and alcoholabuse. The potential mechanisms underlying this relationship will also be explored. Subgroup analyses and the qualitysearch will bediscussed.Conclusions This systematic review will contribute to a better understanding of the interplay between bruxism andalcohol abuse, shedding light on potential risk factors, mechanisms, and clinical implications.
