Concentration of eluted monomers from the composites, in microgram per square centimeter surface area.
Toxicity testing of composites -

None of the tested composite materials was deemed less safe to use than the others, a recent report from NIOM concluded. The release of monomers from the different composites was similar. Initial cytotoxicity screening of extracts of the materials indicated some differences between the products. However, further evaluations could not verify a cytotoxic potential.

CAD/CAM-produced three-unit bridges.
Gap settings matters -

n a recent investigation from University of Oslo and NIOM, none of the three-unit bridges produced with different CAD/CAM systems attained the nominal settings for the cementation gap. The measured gaps were up to twice the sizes set in the CAD-software.
