Visual Pedagogy and Manual Toothbrushing: Participants in this arm will use a manual toothbrush with caregiver support. Visual pedagogy resources will include printed PECS cards illustrating each step of toothbrushing and tactile sensory panels simulating toothbrush bristles, toothpaste texture, and dental floss. Caregivers will be instructed to use these materials daily at home for 3 weeks to improve comprehension, adherence, and cooperation in children with ASD.
Study summary
This randomized clinical trial evaluates the effectiveness of an AI-enabled electric toothbrush and visual pedagogy materials in improving oral hygiene among children with autism spectrum disorder (ASD). The study compares plaque control, gingival health, and adherence between children using a manual toothbrush with visual pedagogy support and those using an AI-enabled electric toothbrush with app-based monitoring.
