The purpose of this study was to evaluate the degree of color stability and examine
the surface change of esthetic restorative materials in various organic solutions. Ten
esthetic restorative materials were used : three chemical-cured composite resins(WC,
PAS, and PAL), four light-cured composite resins(CHA, Z100, AEL, and FLO), three
light-cured polyacid modified composite resins(HYT, DYR, and COM). Specimens were
prepared as disks of 14 mm in diameter and 1.2 mm in thickness. After polymerization,
specimens were immersed in six different solutions(distilled water, artificial saliva with
mucin, 0.1 mole acetic acid solution, 10% hydrogen peroxide solution, and 50% and 75%
ethanol) for 1, 7, 14, 21, 28, 56, 84, 112, and 140 days. The specimens were maintained
at 37 t throughout the study. Color was measured by CIE Lab against to CIE standard
illuminant C reflected on spectrophotometer(CM-3500d, Minolta, Japan.) with specular
component exclusive(SCE). After various treatments, the surface of specimens was
examined by Surface Roughness Tester(Surtronic 3P, Rank Taylor Hobson Ltd.,
England.). From the experiment, the following results were obtained. In distilled water,
specimens showed an acceptable color stability except for CFS. The water hardening
glass ionomer cement, CFS, showed the highest color change(¡âE> 5.0). Color stability
of specimens in artificial saliva with mucin was similar to that in distilled water. CFS
and KTM showed high color change(¡âE > 5.0) and it would not be acceptable in the
clinical situation. In acetic acid solution, all of the glass ionomer cements and compomer
specimens showed high color change due to the dissociation of metal-polyacrylate by
chemical reaction with H+ ions. CFS, FLC, and FLT showed high color
change in ethanol. Color change of specimens in 50 % ethanol was higher than that in
75 % ethanol. 10 % hydrogen peroxide solution resulted in high color change for
chemical-cure glass ionomer cements and destroyed the specimens. FLC and CPG
showed high color change due to oxidation of residual reaction accelerator and inhibitor
by hydrogen peroxide.
