AI Toothbrush and Visual Pedagogy to Improve Oral Hygiene in Children With Autism Spectrum Disorder

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.
