Companies that make dental products do not fully disclose ingredients because they want to protect their patents. I do have the MSDS on diamondlite and if anyone wants it, they can email me. Diamond says their process eliminates residual metals in their fillings (which most other white fillings contain). They call it a PEX-based system, which is a cross-linked polyethylene.

Diamondcrown used for filling material is the most compatible on the market, but for those still wanting a compatibility test, or for those needing work other than fillings and want to know if they test safe for other products, you can get a biocompatibility test. (I recommend this only to people who say they are allergic to everything, but it is up to the patient). Testing info is on my website (scroll down a ways):
