A new research has revealed that children are threatened to get exposed to contentious chemical bisphenol A (BPA), which can be released from the fillings and sealants used by many dentists.
The findings of the study conducted by Dr. Abby F. Fleisch, a pediatrician in the department of medicine at Children's Hospital Boston and colleagues, are published in the October issue of Pediatrics.
The researchers concluded that though the material used by dentists doesn't contain BPA in the purest form, but saliva causes them to percolate that initiates the discharge of chemical into mouth in its real form.
The findings do not include the long term risk associated with the BPA, but the chemical that is also found in plastic products pave way to male impotency, infant behavioral problems and birth defects. But researchers don't prohibit its use.
The researchers based their concluding on the studies conducted on BPA for last 15 years. Citing the usefulness of sealants and fillings, researchers recommended makers to label their sealant products describing the risk they possess. They suggested taking preventive steps to mitigate BPA exposure to children and pregnant women.
Some other researches with laboratory animals brought out that BPA pose threat to cancer and diabetes, brain, prostate and some degree of sexual dysfunction and hyperactivity.
Fleisch said, "There's still a need for additional research looking at both systemic absorption -- as a result of this BPA exposure -- into the blood and the urine".
