Post comments about how dentists are split over BPA to our blog.
Bisphenol-A worries many dentists. This survey found 53% of dentists think the American Dental Association (ADA) should warn the public about the possible dangers of BPA, which can be found in some dental sealants and composite.
On the other hand, 47% think there still needs to be more research into BPA in dental restorations and bisphenol in dental composite. "Look into this more fairly before alarming everyone, perhaps unnecessarily," cautioned one dentist.
We asked dentists, "Should the ADA take a stand against dental bisphenol A?" Here’s what they had to say:
The ADA has a responsibility to protect the public
- "The ADA should conduct a thorough Scientific Study so we do not have another 'amalgam controversy.'" (Kentucky dentist)
- "Whatever the studies show, the ADA needs to get that PR out to the public. We should not do so in a defensive way, but in an educational manner that shows we have done our homework and have the public's best interests in mind. It is all about perceptions. If we say nothing, then the only voice the public hears will be other voices. And then the ADA is doing a disservice to the public and to its members." (General dentist)
We need more research first
- "First determine if in fact there is an issue with BPA leaching out of the material and in what amounts. Find a replacement for it in the formulations. Then announce that you've removed it not because you need to, but to be preemptive." (New York dentist)
- "Look into this more fairly before alarming everyone, perhaps unnecessarily." (New York dentist)
- "The ADA must respond only to true science." (Texas dentist)
- "I think that we need all appropriate in vivo experimental and clinical studies in order for the proper authorities to rule one way or the
The risks are serious
- "BPA is linked to female issues. We need to be preemptive, even if there is a doubt. What are they waiting for, a return to amalgams?" (Michigan dentist)
- "I have a one year old and we make sure never to have him use bottles or other items made of BPA. Most companies that produce products placed in babies mouths are removing BPA from them (bottles, pacifiers, etc). Therefore, why should dentists continue to use dental sealants with BPA?
It doesn't make a whole lot of sense." (Ohio prosthodontist)
Amalgam all over again?
- "With the push to eliminate amalgam from dentistry due to its mercury content & the potential [??] risk from Bisphenol A (BPA), that leaves us with gold as the only safe restorative material. Who is going to pay for it??" (Connecticut dentist)
- "What do the anti-amalgamists say about BPA risk? It seems to me they should jump on this bandwagon also."
BPA and bis-GMA are different
- "It is my understanding that BPA itself is not an ingredient in composite materials, but bis-GMA, which is made from BPA. The amount of unconverted BPA in dental materials is almost undetectable and has not been shown to be a health threat. There is also no better alternative material for long-term restoration of the dentition."
Note: Survey sample included 58 respondents.
