Baby teeth may predict autism, says study

1 min read Children's dentistry
Scientists suggest evidence found in baby teeth can be used to predict who might develop autism.

Researchers suggest that cycles involved in zinc and copper metabolism are dysregulated in autism spectrum disorder (ASD) and can be used to predict who will later develop it.

They used the teeth to reconstruct prenatal and early-life exposures to nutrient and toxic elements in healthy and autistic children.

Results of the study were published online in Science Advances, a journal published by the American Association for the Advancement of Science.

This is the first study in the world to generate a 90% accurate fetal and early childhood biomarker of ASD using a longitudinal analysis of distinct metabolic pathways, and to replicate it in four independent study populations.
