Background: Sleep hygiene measures and meditation may reduce stress and improve sleep quality, but their effect on the occurrence of sleep bruxism in children has not yet been investigated. Aim: To explore the effects of sleep hygiene measures combined with mindfulness meditation (relaxation audio) in the management of probable sleep bruxism (SB) in children. Design: This clinical trial (no. NCT04501237) randomized 36 children with 3–8 years of age. Probable SB detection was performed according to the criteria established by the International Consensus on The Assessment of Bruxism—2018. Intervention group was instructed to practice sleep hygiene measures and mindfulness meditation (i.e., the use of a digital app to broadcast audio relaxation) each night before bedtime for 5 weeks; control group did not receive guidance for therapies. Parents completed a bruxism diary for 5 weeks, and the outcome was the number of SB episodes‐day reported in the week (ranging from 0 to 7) in each period. A multilevel mixed‐effects Poisson regression model was performed. Results: A total of 32 children (mean age: 6.1 years) completed the study. The children who received the therapies related to sleep hygiene measures and mindfulness meditation had a reduction in the SB incidence rate ratio (IRR) of 46% (IRR = 0.54 [Confidence Interval 95%, 0.45–0.65]) during a 5‐week observation period. The sensitivity analyses did not show relevant changes in the measure of the effect. Conclusion: Sleep hygiene measures combined with mindfulness meditation reduced the SB in children.

Objective: This study aimed to evaluate the prevalence of probable sleep bruxism (SB) in children aged 7–8 years and its association with sleep pattern and the time spent using devices with a screen. Material and Methods: A cross‐sectional study was conducted with children from Pelotas, Brazil (n = 556). Parents/caregivers were interviewed and provided demographic/socioeconomic information, children's daily screen time, nighttime tooth grinding or clenching, sleep duration and answered the Biological Rhythms Interview for Assessment in Neuropsychiatry for Kids (BRIAN‐K‐sleep domain). Probable SB was determined based on a positive clinical inspection with/without a positive parental/caregiver's reports of tooth clenching or grinding. Hierarchical Poisson regression was performed. Results: The prevalence of probable SB was 15.83% (n = 88). There was no difference in the probable SB prevalence according to the daily screen time (p = 0.744), and low family socioeconomic status was associated with higher SB prevalence (Prevalence Ratio [PR] = 1.95; 95% Confidence Interval [95% CI]: 1.21–3.17; p = 0.006). Higher scores in the sleep domain of the BRIAN‐K scale were associated with probable SB [PR = 1.07; 95% CI: 1.01–1.30; p = 0.013]. Conclusions: Difficulties in maintaining sleep and low family socioeconomic status were associated with probable SB in schoolchildren, while screen time spent using devices with a screen was not associated.
