RESUMO
BACKGROUND: Children diagnosed with autism spectrum disorders are shown to have poor periodontal health and dental hygiene habits. Extensive research has revealed that parents of children with autism spectrum disorder (ASD) frequently encounter heightened levels of stress, despair, and anxiety in comparison to parents of neurotypical children. The aim was to understand the relationship between the dental hygiene of children with ASD and the stress generated in their parents. Methods: A scoping review was carried out to identify any gaps or research opportunities for clinical practice concerning oral care and stress levels in parents in the PubMed, Medline, ScienceDirect, and Scopus databases. Results: A total of 139 articles were reviewed. Of these, only 10 met the selection criteria for inclusion. Our results reveal a lack of studies presenting evidence on the topic of poor dental hygiene in children with ASD and high stress levels in their parents. Discussion: There is ample evidence that children with ASD have poor dental hygiene, as well as higher levels of stress in their parents. However, little or no evidence links these two variables. Future studies should focus on this link, which could have practical implications for improving dental care for children with ASD.
