Abstract
This study examined the effect of surface roughness on the color of silorane-based composite exposed to staining solutions. Two methacrylate-based resin composites (Filtek Z250, Filtek Z350) and one silorane-based resin composite (Filtek P90) were light cured for 20 seconds and polished with SiC paper (#320, #600, #1000). The color of the specimens was measured in %R (reflectance) mode before and after immersing the specimens in coffee (0.89wt%) as test solution for 7 days. The color difference (ΔE*) was obtained based on the CIEL*a*b* color coordinate values. The surface roughness did not significantly influence the color stability of silorane-based and methacrylate-based composite. The silorane-based
composite exhibited better color stability than methacrylate-based composite.
