Effects of incorporating zinc oxide and graphene oxide nanoparticles on abrasion, translucency, and microhardness of flowable composite resin: In vitro .

Incorporation of NPs into flowable composite resin resulted in a decrease in translucency. The microhardness was reduced in groups containing ZnO, but the abrasion was also reduced in these groups. The incorporation of GO did not significantly alter the abrasion and microhardness of the composite resin.
