FOR IMMEDIATE RELEASE
With recent news of possible health threats from the chemical bisphenol-A, one in four dentists reports being very concerned about the presence of BPA in dental composite and dental sealants.
May 25, 2008 (San Francisco, California) One dentist in four reports being very concerned about the issue of bisphenol-A in dental composite and sealants in a recent survey by dental continuing education resource The Wealthy Dentist. Even those dentists who aren’t worried are following this developing story with interest.
Composite and sealants have been in the spotlight recently thanks to the chemical bisphenol-A (BPA). Found in many plastics (including some water bottles and baby bottles), this monomer seems to mimic the effect of the female hormone estrogen.
The scientific evidence on the subject is muddy. BPA has been shown to have feminizing effects in animal studies. Many humans have measurable levels of BPA in their blood. Dental sealants may contribute to BPA exposure. But many argue that the levels to which humans are exposed are far too low to have significant health effects.
A number of dentists are worried about the health implications of BPA in dental work. “I am particularly concerned about using composites and sealants in children,” said a Texas dentist. "If the public is worried, so am I. I had fellow church members ask me if they needed to get all their composites removed last Sunday," said a New York dentist.
A number of dentists feel that BPA is unlikely to be a health threat. “Slow news day?” asked a Georgia dentist. "The cumulative release of BPA from composites appears to be minimal from the available research,” said a New Hampshire dentist.
Dentists report varying levels of patient concern. "My patients are not particularly worried. They depend on me to do the research and make decisions about material safety," said a Texas dentist. “Patients are concerned,” offered an Illinois pediatric dentist.
Bisphenol-A isn't the only health concern when it comes to resin restorations. “Forget about bisphenol-A. Resins are far more toxic on a cellular level than amalgam," said one general dentist. "Are you familiar to amalgam studies showing how cells in a petri dish respond to amalgam? They continue to happily divide. When unset resin is placed the cells die!"
Some were reminded of the issue of mercury in metal dental fillings. “It's the amalgam issue all over again. What are all the ‘Bondadontists’ going to tell their patients now?” asked a Virginia dentist. "It's likely more of an issue than the bound mercury in amalgam," declared a Texas endodontist.
A few are most concerned about the impact this news will have on the dental profession. “It doesn't matter if composites and sealant are safe. If public perception is that they are not, it is very harmful to dentistry,” declared a Utah dentist.
"It’s hard to tell at this point if this is a real health threat or just another false alarm," said Jim Du Molin, dental patient marketing guru and founder of dental practice marketing resource The Wealthy Dentist. "But you can be sure that dentists will be following this developing story with interest."
