No Bisphenol A in Dental Sealants

There has been much media buzz lately about the chemical in plastics known as Bisphenol-A. Found in a variety of household products it has been linked to infertility, cancer, behavioral disorders and the like. This evidence is tenuous at best but cause for concern is being raised by scientific, health, and government institutions. Unfortunately many media reports have indicated that Bisphenol A can be found in dental materials, most notably sealants. Unfortunately the media tends to be it's own source for things and such misinformation can be endlessly Googled and repeated by well meaning, albeit lazy journalists.
Current dental sealants do not contain Bisphenol-A and have not for many years. Below is a quote from a blog on Ultradent"s website (A popular and respected dental material company whose sealants and bonding agents I have used for years)

Results from testing for Bisphenol-A

Dear Colleagues
The media continues to address the health concerns over Bisphenol-A. As is often the case, they serve an important role in bringing public safety issues to light. To support you in communicating with your patients about these concerns, we want to provide you with additional third-party evidence that our own sealants are void of such contaminants.

After testing through a well-respected laboratory, we received tests results that indicate a 0.00000% presence of Bisphenol-A in our UltraSeal XT plus. This is the same type of test we conducted over 12 years ago – the results remain the same. Our sealant is alternatively composed of Bis-GMA, like many currently available dental sealants. Despite this, I encourage others to undergo the same testing to bring confidence back to clinicians and patients alike.
