Abstract
The purpose of this study was to investigate the color stability of composite resins used widely as esthetic restorative material.Surefil(Dentsply,U.S.A.),Esthet X(Dentsply,U.S.A.),Filtek P60(3M,U.S.A.),Filtek Z250(3M,U.S.A.),Synergy Compact(Coltene,Switzerland),and Synergy Duo(Coltene,Switzerland)were chosen for this study.Thirty six specimens(7mm x2mm) of each composite resin were fabricated and polished after polymerization.Treatment conditions designed for this study were thermocycling,methylene blue staining,and filtered coffee staining. The color changes before and after treatment were measured by colorimeter(colorimeter,Model Tc-6Fx,Tokyo Denshoku Co.)and analyzed. The followings were drawn from this study:1.The color changes of Filtek Z250,Surefil,Filtek P60 and Esthet X after thermocycling for 3 weeks were greater than those of the others. 2.The color changes of Surefil and Esthet X after methylene blue staining and those of Surefil, Filtek Z250 and Filtek P60 after coffee staining were great. 3.The color changes of Synergy Duo and Synergy Compact after thermocycling and coffee staining were relatively lesser than those of other composite resins.
