 The purpose of this study is to test a parent-training intervention designed to improve home dental hygiene, compliance with dental office visits, and oral health outcomes in children with autism spectrum disorder. Families of children ages 3 to 13 years with an existing diagnosis of ASD will be recruited for participation. All families will receive the Autism Intervention Research Network on Physical Health AIR-P Dental Toolkit, which is designed to provide parents with guidance and information about dental care and support strategies for children with ASD. Some families will also participate in a 10-week behavioral parent-training intervention focused on improving home dental care and dental office visit experiences.
