Male and female children aged six to eight years with no physical or psychiatric limitations that may compromise the proposed therapies will be included. All individuals will need to have the first molars in Angle Class I and be free of dental caries. A clinical examination of tooth wear and the reports of parents/caregivers regarding tooth clenching/grinding will be used for the diagnosis of bruxism, following the criteria established by the American Academy of Sleep Medicine1 and the use of a questionnaire adapted by Serra Negra (2014).
