The Use of Audiovisual Distraction Tools in the Dental Setting for Pediatric Subjects with Special Healthcare Needs: A Review and Proposal of a Multi-Session Model for Behavioral Management.

Background: A Special Health Care Need (SHCN) is characterized by any type of physical, mental, sensorial, cognitive, emotional, or developmental condition that requires medical treatment, specialized services, or healthcare interventions. These conditions can negatively impact oral health as SHCN children can hardly cooperate or communicate and experience higher levels of dental fear/anxiety, which interfere with regular appointments. The present narrative review aims to analyze the use of audiovisual (AV) tools in dental setting for the management of SHCN children during dental treatment and to evaluate their effectiveness in anxiety/behavior control from the child, dentist, and care-giver perspectives. This analysis leads to the proposal of a new multi-session model for the behavioral management of SHCN pediatric subjects.

Methods: An electronic search on the MEDLINE/Pubmed, Scopus, and Web of Science databases was carried out and through this analysis, a new model was proposed, the "UNISA-Virtual Stepwise Distraction model", a multi-session workflow combining traditional behavior management and the progressive introduction of AV media to familiarize the SHCN child with dental setting and manage behavior.

Results: AV tools helped in most cases to manage SHCN behavior and decreased stress in both the dentist and child during dental treatments. Care-givers also welcomed AV distractors, reporting positive feedback in using them during future treatments.

Conclusions: The present narrative review found increasing evidence of the use of AV media for SHCN pediatric subjects as distraction tools during dental treatment. In the majority of the studies, AV tools proved to be effective for the management of anxiety, dental fear, and behavior in dental setting.
