Mikey,
Dental restorative materials (aka poison) are patented . When one obtains a patent on a chemical compound , they give up their right to keep their ingrediants a secret in exchange for a monopoly on profits from the product . If you live in the L.A. area , I suggest you go to the main library at 5th and Flower in downtown LA. They have a patents dept and they can probably help you find out the contents of dental products.
On the curezone ask Torrie forum on 5/21, someone called the messiah posted information on diamond products . According to the messiah, diamond products have formaldehyde, a potent carcinogen and phenolic epoxy matrix.
