Getting to the tooth behind bad behavior

A new study published in the medical journal, Pediatrics, suggests a possible link between plastic fillings and behavioral problems in children, including anxiety and depression. The plastic fillings contain the chemical bisphenol A, which has previously been linked to hyperactivity in children who received pre-natal exposure.

They found that children who had BPA-containing fillings for at least five years “consistently scored two to six points worse on 100-point behavior measures than those who had none of the fillings or who’d only had one for a short time,” indicating possible leaching of BPA into the mouth and digestive system.

The researchers are careful to note that they did not measure BPA levels in the fillings. Also, they’re not sure if it was BPA or other chemicals in the fillings causing problems. And, they did not test the children’s behavior for interspecies mating.
