ABSTRACT
Abstract This study aimed to determine the impact of the COVID-19 pandemic on sleep quality and possible sleep bruxism (SB) in children eight to ten years of age. The study hypothesis was that sleep disturbances influenced a higher occurrence of bruxism during the COVID-19 pandemic. A longitudinal study was conducted at two time points in person prior to the COVID-19 pandemic (T1), and online during the pandemic (T2). The sample comprised 105 children. Parents/caregivers answered a questionnaire addressing sociodemographic characteristics, the use of electronic devices, reported (vs. clinical) SB, and the Sleep Disturbance Scale for Children (SDSC) at both T1 and T2. McNemar's and Wilcoxon's tests were used to compare SB and sleep disorders at both time points. Poisson regression analysis determined the relative risk (RR) among the variables, and the incidence of possible SB (p≤0.05). The comparison of the two time points (T1 and T2) revealed a significant increase in possible SB (p<0.01) and sleep disorders (p < 0.04). Children whose parents had a lower schooling level (RR 2.67; 95%CI 1.19-6.01), those with their own electronic devices (RR 1.97; 95%CI 1.09-2.50), and those with sleep disorders during the pandemic (RR 1.74; 95%CI 1.35-2.24) were at greater risk of developing SB during the pandemic. Moreover, the incidence of bruxism and sleep disorders was greater during the pandemic. The factors influencing SB incidence during the pandemic were a lower level of mothers' schooling, greater access to electronic devices, and the occurrence of sleep disorders.
