Year: 2025

Abstract: Aim: This study aimed to investigate the association of probable sleep bruxism with stress and quality of life in children. Methods: A cross-sectional study was conducted with 117 children, aged 8–11 years, from public schools in São Luís, Maranhão, Brazil, from March to December 2019. A questionnaire with demographic and socioeconomic questions, aspects related to sleep bruxism, and deleterious oral habits was answered by parents. The children underwent clinical examination and then answered the Childhood Stress Scale and the Autoquestionnaire Qualité de Vie Enfant Imagé (AUQUEI). Data were subjected to descriptive, bivariate, and multivariate analyses (hierarchical Poisson regression models) at 5% significance level. Results: A brown race prevailed in the sample (70.1%). Probable sleep bruxism and stress were observed in 11.1% and 38.5% of the children, respectively. The “family” and “function” domains of AUQUEI were the most impaired (10,892.20 and 10,211.87, respectively), while probable sleep bruxism was not significantly associated with stress (p=0.293). Conclusions: Based on these findings, it can be concluded that probable sleep bruxism was not associated with stress or a negative impact on children’s quality of life.
