Thank you for the information. If the composite is visible on X-ray for sure there is metal in it, otherwise it would not be detectable. Regarding Bis-GMA, I cannot find any direct composite that does not contain it. Do you know what DiamondLite from DRM Res. Labs contains for it to be X-ray detectable? Cadmium or Mercury? It just states FDA approved pigments on the MSDS sheet.

Do you know if any dentist willing to use DiamondLite as a composite?
