Excess consumption of refined sugar and increased use of recreational screen time are risk factors for alterations in the quality of life that have been associated with sleep bruxism in children and that compromise the same mechanisms of alteration of the reward system in the brain. Therefore, the question of this research is: What is the effect of the Intervention "Food, Fun and Family (FFF)" on the frequency of sleep bruxism in children? The general objective of the research is to evaluate the effect of the Intervention "Food, Fun and Family (FFF)" on the frequency of sleep bruxism in 84 children who attend the pediatric dentistry postgraduate clinic of the CES University and the private consultation Dr. Claudia Restrepo and Dr. Adriana Santamaría. The frequency of sleep bruxism will be evaluated with the translated and validated Spanish version of the Children's Sleep Habits Questionnaire (CSHQ), which will be answered by the parents. The consumption of added sugar will be evaluated with the version translated into Spanish of the Health Behavior in School-Aged Children - Food-Frequency Questionnaire (HBSC-FFQ). The time on screens will be recorded through the parents' report, of the time in hours that the child spends using electronic media in a recreational way each weekday for a week and each weekend day for a week.

A decrease in the frequency of sleep bruxism is expected to be found by reducing sugar consumption and screen time in the children evaluated.

The results of this study will be presented at the IADR, ACFO, ACOP and CES University research meetings and will be published in a peer-reviewed scientific journal in category Q1.
