Bruxismo infantil e fatores associados: uma revisão de literatura.

Abstract

Bruxism is a motor behavior of multifactorial etiology, resulting from repetitive movements of muscles in conjunction with the mandibular position, being directly linked to the central nervous system, with a high prevalence in childhood. The aim of this study was to determine the factors that are related to bruxism in children through a literature review. A review of articles published between the years 2016 to 2021 was conducted through the digital platforms PUBMED, SCIELO and GOOGLE SCHOLLAR. Twenty-five (25) articles were analyzed, comprising cross-sectional studies, systematic reviews, meta-analyses and case-controls, which met the study's inclusion criteria. Through the analysis of the results, it was seen that the risk factors that are indicative of bruxism can manifest in different ways in children. It was concluded that sleep disorders, respiratory problems, harmful habits such as biting objects, lips and cheek, mouth breathing, tooth wear, stress, anxiety, maternal psychological traits, genes, low socioeconomic status, passive smoking and Deficit Disorder Attention/Hyperactivity (ADHD) are associated with bruxism in children.
