What is the purpose of this trial?

This trial aims to determine if a specially modified app can help teens with autism improve their toothbrushing skills and habits. Participants will be divided into two groups: one will use the enhanced app, which includes a digital social story for guidance, and the other will use a basic version with a timer and selfie mirror. Teens aged 10 to 17 with autism who can mostly brush their teeth independently and use a smartphone or tablet might be suitable candidates. The trial will compare changes in each group's brushing habits over a few months. As an unphased trial, this study offers participants a unique opportunity to contribute to innovative research that could enhance daily living skills for teens with autism.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that this mobile app is safe for teens with autism?

Research has shown that using mobile apps to help children, including those with autism, brush their teeth is generally safe. Studies have not identified any safety problems with these apps or other tech tools designed to improve children's toothbrushing habits. Although researchers continue to monitor safety, no short-term negative effects have been reported. This suggests that the app used in this trial should be safe for participants. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it's exploring a fresh approach to improving toothbrushing skills in teens with autism using a mobile app. Unlike traditional methods, which might involve direct teaching or physical aids, this app incorporates a digital social story, a technique that's particularly effective for kids with autism. It also uses interactive elements like a digital selfie mirror and a timer to make toothbrushing a more engaging activity. By combining these features, the trial hopes to find out if such a tailored digital tool can make a real difference in building better oral hygiene habits for teenagers on the autism spectrum.

What evidence suggests that this mobile app is effective for improving toothbrushing skills in teens with autism?

Research has shown that mobile health apps can significantly enhance toothbrushing skills in children with autism. One study found that an app called “Marzhan Tis” helped children on the autism spectrum improve their oral hygiene skills. Additionally, children using similar apps completed 33.7% of the steps needed for effective toothbrushing. These findings suggest that mobile apps designed for autism can lead to better toothbrushing habits and skills. In this trial, participants in the experimental arm will use a mobile app specifically designed to improve toothbrushing skills and habits in teens with autism. The study results are promising for improving oral hygiene in teens with autism using this technology. ^{3 4 6 7 8}

Are You a Good Fit for This Trial?

This trial is for teens aged 10-17 with Autism Spectrum Disorder who brush their teeth mostly unassisted, use touch screen devices, and live with a caregiver. The caregiver must be over 18 and able to consent in English. Participants need access to a mobile device with a camera and internet connection.

Inclusion Criteria

The child and caregiver live together in the same home.

Children who use smartphones or tablets.

I am over 18 and can consent in English.

What Are the Treatments Tested in This Trial?

Interventions

• Testing a Mobile App to Improve Toothbrushing Skills and Habits in Teens With Autism

Trial Overview

The study tests an app designed to improve toothbrushing skills in autistic teens against a control app. Over six years, it will modify the existing app, pilot it during the first two years, then compare behavior changes between groups using surveys and interviews.

How Is the Trial Designed?

Group I: Experimental Experimental Treatment 1 Intervention

Children in the experimental arm will receive the same health education module as in the control arm. They will also receive a brief tutorial on additional app components in the form of a digital social story, which is an effective way to convey information to children with autism. Participants will be completing 26-item Behavioral Survey at 2 weeks, 1 month, 2 month, and 3 month. Participants will be using the app during toothbrushing 2x a day for 3 months under direct supervision of the caregiver.

Group II: Control Experimental Treatment 1 Intervention

The control arm will consist of a 20-second health education module delivered through the control app that consists of a digital selfie mirror and a timer that matches the length of brushing time in the experimental app. Participants will be completing all the survey activities similar to that of the participants in the experimental arm.

A four-month tooth brushing learning program using pictograms on an iPad significantly improved tooth brushing skills in 52 children with autism spectrum disorder (ASD), aged 3 to 19 years.

The program not only enhanced the children's ability to brush their teeth but also increased their interaction with the iPad, suggesting that technology can be an effective tool for teaching oral hygiene to children with ASD.

A randomized control trial involving 18 children with autism tested a 3-week internet-based video-modeling intervention for improving oral hygiene, showing that both the intervention and control groups improved their oral health.

However, the children in the Intervention group demonstrated significantly larger improvements in their oral hygiene, suggesting that video modeling could be an effective method for enhancing at-home oral care in children with autism.

The MyDentist project, which involved 59 children with autism spectrum disorder (ASD), successfully improved oral hygiene and cooperation during dental treatments over a 6-month period using Information and Communication Technologies (ICT) for desensitization and fear control.

Parents reported high acceptability of the MyDentist experience, indicating that effective dental care for children with ASD can be achieved through innovative, non-pharmacological approaches, reducing the need for costly medications with potential side effects.

An iPad®-based training program significantly improved toothbrushing behaviors in 52 children and teenagers with autism spectrum disorder (ASD) over an 8-month period.

The program not only enhanced the children's autonomy in oral care but also made it easier for caregivers to implement effective toothbrushing routines, as shown by significant improvements in all assessed variables.

Both video modeling (VM) and toothbrushing social story (TSS) interventions significantly improved oral hygiene in children with autism spectrum disorder (ASD) after 30 days, as measured by plaque and gingival indices.

Caregivers reported greater acceptance of daily oral hygiene practices in the VM group compared to the TSS group, suggesting that VM may be a more effective method for encouraging oral hygiene in children with ASD.
