Abstract

Four composite resins, polished by different methods, were tested for staining and/or penetration by staining solution.Surface set cured against slide glass(smooth surface), white point-polished surface and finishing surface were prepared for each materials, and immersed in 0.2% Fuchsin solution at 37℃ for 60 days.The staining was evaluated by measuring of Adams' color difference(ΔE)before and after 3, 10, 20, 30, 40, 50, 60 days of immersion period, respectively.After 60 days, specimens were sectioned thinly and longitudinally.They were observed with a polorization microscope, and the thickness of the staining layer was measured.Finishing surface had a lower ΔE value than smooth and white point-polished surface.The thickness of the staining layer of finishing surface was significantly thinner than that of smooth and white point-polished surfaces(P<0.01).The ΔE value of every surfaces showed some correlation with the thickness of the staining layer.Microrest had a lower ΔE value and lower thickness in staining layer than the other resins.
