In this study, BisGMA and TEGDMA as monomers were used to fabricate dental composites. Camphorquinone was used for photopolymerization using LED light curing unit. To prepare filled resin based dental composites, different wt. % (5, 10, 15, and 20) of nanosilica were used. Unfilled and filled samples were prepared to test for volumetric wear. To access the effect of filler content, normal load, sliding velocity and number of cycles using L25 orthogonal array, wear tests were performed on pinondisc apparatus using different levels of process parameters. Using Taguchi methodology and ANOVA, volumetric wear is analyzed, and it is revealed that the filler content is the most significant parameter which affects volumetric wear of nanosilica filled dental composites.
