Fig. 2From: Cytotoxicity and reactive oxygen species production induced by different co-monomer eluted from nanohybrid dental compositesSEM images of agglomerated submicron-sized and spherical filler particles (magnification: left, 1,000 × ; centre, 5,000 × ; right, 30,000 ×). Submicron and nanofillers were aggregated to large spherical-shaped fillers (asterisk in CX and DN) that are dominant in CX and DNBack to article page
