A study has revealed that sealants and fillings used on children’s teeth may expose them to bisphenol A (BPA), says an article in the medical journal Pediatrics. The researchers say it is not yet clear whether this is hazardous to the long-term health of a child, as exposure does not generally last long. Dental sealants, which contain a variety of BPA derivatives are effective in preventing the majority of dental cavities in children and teenagers.
Researchers from The Children’s Hospital, Harvard Medical School, Departments of Pediatrics and Preventive Medicine, Mount Sinai School of Medicine, New York, and Columbia University College of Dental Medicine, New York set out to evaluate the BPA content of dental materials and find ways to manage BPA exposures.
The authors stress that dental materials present a far smaller and much less frequent exposure to BPA than other sources might, such as plastic food-storage containers, the linings of metal food cans, and some water bottles.
Reducing exposure to BPS is important for health, especially after prior research had discovered that BPA can pose health risks from its endocrine-disrupting, estrogen-like properties.
