BPA Harms Dental Enamel In Young Animals, Mimicking Human Tooth Defect
A tooth enamel abnormality in children, molar incisor hypomineralization (MIH), may result from exposure to the industrial chemical bisphenol A (BPA), authors of a new study conclude after finding similar damage to the dental enamel of rats that received BPA. The study results will be presented Friday at the Endocrine Society's 97th annual meeting in San Diego. "Human enamel defects may be used as an early marker of exposure to BPA and similar-acting endocrine disruptors," Babajko said. BPA is an endocrine disruptor, or hormone-altering chemical, that has been linked to numerous adverse health effects in humans. It appears in many plastic and resin household products and food containers, including until recently baby bottles, sippy cups and infant formula packages. read more
