Objetivo: verificar a preval?ncia e os fatores associados ao bruxismo noturno em escolares brasileiros de 8 a 10 anos de idade. M?todos: realizou-se um estudo transversal com uma amostra representativa de 473 escolares, matriculados em escolas p?blicas e privadas das cidades de Serro e Gouveia, Brasil. As informa??es sobre presen?a de bruxismo noturno, fatores socioecon?micos, presen?a de h?bitos bucais delet?rios, problemas respirat?rios e aspectos psicol?gicos da crian?a (nervosismo, ansiedade e agita??o) foram obtidas atrav?s de question?rios respondidos pelos pais/cuidadores. O estresse dos pais/cuidadores foi avaliado atrav?s do instrumento Invent?rio de Sintomas de Stress para adulto de Lipp (ISSL). O instrumento Family Adaptability and Cohesion Evaluation Scales (FACES III) investigou o n?vel de coes?o e adaptabilidade familiar. O estresse infantil foi avaliado por meio da Escala de Stress Infantil (ESI). Os dados foram analisados pelo programa Statistical Package for Social Sciences (SPSS para Windows, vers?o 20,0, SPSS Inc. Chicago, IL, EUA). A an?lise dos dados incluiu an?lise descritiva, testes qui-quadrado e regress?o de Poisson com modelo hier?rquico (p<0,05). Resultados: a m?dia de idade das crian?as foi de 9,15 anos (DP=0,8 anos) e 55% pertencia ao sexo feminino. A maioria dos pais apresentava menos de 8 anos de estudo (54%) e 47% das fam?lias possu?am renda mensal familiar inferior a 2 sal?rios m?nimos. A preval?ncia de bruxismo noturno foi de 39,5% (n = 187). O bruxismo noturno foi significativamente mais prevalente entre crian?as que apresentavam onicofagia (RP: 2,08; IC 95%: 1,50-2,88) e suc??o digital (RP: 1,45; IC 95%: 1,04-2,01). Conclus?es: A preval?ncia do bruxismo noturno em crian?as de 8 a 10 anos de idade foi alta. Crian?as com hist?rico de onicofagia e de suc??o digital apresentaram maior preval?ncia de bruxismo noturno. === Disserta??o (Mestrado) ?

Objective: The aim of the present study was to determine the prevalence and factors associated with sleep bruxism in Brazilian schoolchildren aged eight to 10 years. Methods: A cross-sectional study was conducted employing a representative sample of 473 schoolchildren enrolled in public and private schools in the cities of Serro and Gouveia, Brazil. Data was collected on sleep bruxism, socioeconomic factors, harmful oral habits, respiratory problems and psychological aspects (nervousness, anxiety and agitation) through the use of questionnaires filled out by parents/caregivers. Parent/caregiver stress was evaluated using Lipp?s Adult Stress Symptoms Inventory. The Family Adaptability and Cohesion Evaluation Scales (FACES III) were also used. Child stress was evaluated using the Child Stress Scale. The data were analyzed using the Statistical Package for Social Sciences (SPSS for Windows, version 20.0, SPSS Inc. Chicago, IL, USA). Data analysis included descriptive analysis, the chi-square test and hierarchical Poisson regression (p<0.05). Results: The prevalence of sleep bruxism was 39.5% (n=187). Sleep bruxism was significantly more prevalent among children who exhibited nail biting (PR: 2.08; CI 95%: 1.50-2.88) and thumb sucking (PR: 1.45; CI 95%: 1.04-2.01). Conclusions: The prevalence of sleep bruxism among children aged eight to 10 years old was high. The prevalence rate was higher among children with a history of nail biting and thumb sucking.
