No Bisphenol A, No Bis-GMA and no BPA derivatives for white fillings

I’ve been asked by patients who are concerned about the BPA release in composite fillings as alluded to in my previous blog. I have a new material listed below which releases no BPA and is available upon request for your fillings. I don’t generally use it because it is not as esthetic or as well tested for durability. The composites I generally use release a very small amount of BPA and is very safe. But for those who maybe sensitive to it or don’t like the idea of BPA there is an alternative, Activa. I like using it for hard to reach areas which can be hard to light cure since it is a dual cure material.

ACTIVA™ BioACTIVE-RESTORATIVE™ – Product Review
BioACTIVE Products for ProACTIVE Dentistry
Changes everything you know about traditional composites, glass ionomers and RMGIs
The Dental Advisor 5 Star Clinical Performance Report

ACTIVA BioACTIVE-RESTORATIVE is a highly esthetic, bioactive composite that delivers all the advantages of glass ionomers in a strong, resilient, resin matrix that will not chip or crumble. It chemically bonds to teeth, seals against bacterial microleakage, releases more, calcium, phosphate and fluoride and is more bioactive than glass ionomers, and is more durable and fracture resistant than composites.

ACTIVA is the first bioactive composite with an ionic resin matrix, a shock-absorbing resin component and bioactive fillers that mimic the physical and chemical properties of natural teeth. It releases and recharges with calcium, phosphate and fluoride ions,1,7,9,11 delivering long-term benefits and better oral health care for your patients.

ACTIVA contains no Bisphenol A, No Bis-GMA and no BPA derivatives.

Composite Restorations or “White Fillings” and the surrounding controversy

Composite Restorations or “White Fillings” and the surrounding controversy

A little history
The dental industry used to and still do use Amalgam to do fillings since the early 1900’s. Amalgam is an amalgamation of mainly silver and mercury with small amounts of zinc, copper and other trace mineral. Since the 1980’s the industry started using composite, a resin to fill the need for a more durable, easier technical properties and more aesthetic material. Resins are also used in sealants. Generally used in youths 16 years and younger.
Where we are now
Over the last several years the health community has brought to our attention that plastics have a softening chemical Bisphenol-A (BPA) which is toxic. No manufacturer uses BPA in their resin. Although plastic drinking water bottles and other plastics used with food is of concern. Bis-GMA is used in composite fillings which does release BPA. The amount of BPA released is very small. There is no manufacturer which has a composite filling material which is BPA free. The choices available to avoid BPA are silver-mercury amalgam, porcelain, white (silver) or gold cast metal restorations. Only porcelain is tooth colored but is bonded to the tooth with a chemical containing minute amounts of BPA.
Some links to information on health and composite fillings
This is a very informational page written by Dr. Michael Goldman in Maryland. He surmises as I do that the so called BPA free composite Diamond Lite has no written proof of that fact. Also that it’s chemistry which is phenol based is not proven to be healthier.
