Baby teeth hold clues to autism?

Posted: Updated:

Some scientists are taking a rather unusual approach as they try to figure out what causes autism. They're actually looking at baby teeth to try and learn more about the complex disorder.

 Donated teeth from children with and without autism are ground into powder and made into liquid and gas.

It allows researchers to look for compounds like pesticides, plastics, and even medicine the child was exposed to in the womb and as they grew.

According to Ray Palmer from the University of Texas Health Science Center, It's been done by looking at blood or hair analysis. But that's only a snapshot in time of recent exposure.  It doesn't provide a historical record of exposure like the teeth do. So, when the teeth are forming, that's a record of what you've been exposed to in utero."

Many scientists think a genetic predisposition combined with environmental exposure triggers autism.
