What this trial studies

This trial aims to modify an existing toothbrushing app specifically for teens with autism and evaluate its effectiveness compared to a control app. The study will be conducted in two phases: the first phase will focus on app modification and pilot testing, while the second phase will involve recruiting 270 participants aged 10 to 17 years to assess toothbrushing outcomes. Participants will use the app, complete surveys, and engage in feedback sessions to inform behavior change. The goal is to enhance toothbrushing habits and reduce the risk of tooth decay in this population.

Who should consider this trial

Good fit: Ideal candidates are adolescents aged 10 to 17 years diagnosed with Autism Spectrum Disorder who can independently brush their teeth and use touch screen devices.

Not a fit: Patients who are unable to brush their teeth independently or do not have access to a mobile device may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve oral hygiene and reduce dental issues among teens with autism.

How similar studies have performed: While mobile health apps have shown promise in various health interventions, this specific approach targeting toothbrushing habits in teens with autism is relatively novel.
