Toxicity of L929 and HGFs on different surface-treated titanium, zirconia and BioHPP after 48 h. Toxicity of L929 and HGFs on controls and surface-treated titanium (A), zirconia (B) and BioHPP (C) disks after 48 h of incubation. UV light treatment led to significantly decreased toxicity on titanium and zirconia, and NTP on zirconia, using L929 cells. However, there were no significant differences on titanium, zirconia and BioHPP using HGFs.
