Observational Study of Oral Microbiota in Children With Autism

NIH added a new ClinicalTrials.gov registry entry for NCT07538232, an observational study examining oral microbiota distribution and salivary IgA in children diagnosed with autism spectrum disorder. The study employs non-invasive sample collection (dental plaque and saliva) with no experimental treatment arms.

Healthcare providers, clinical researchers, and institutions studying autism spectrum disorders or pediatric oral health may use these registry findings to inform future research directions. The study contributes to the growing body of literature on gut-oral microbiome connections in neurodevelopmental conditions, though this registration itself imposes no compliance obligations.
