This is an in vitro reflection spectrophotometric studs, which evaluated the color stability of Ionomer and resin composite materials in, various environmental solutions. Three Ionomer based esthetic restorative materials were used:-Glass Ionomer(GIs), resin modified glass Ionomer(RMGIs), and compomers. A light cured resin bonded composite (RBC) was used as control. Disk type specimens were prepared and aged in four different solutions (deionized water, 75% ethanol. 0.1 mole acetic acid solution & 10% hydrogen peroxide) . for 1,7,14,21,28 and 56 days. The color changes were measured by a reflection spectrophotomer. In deionized water, all specimens showed an acceptable color stability. In ethanol, resin modified glass ionomers(RMGIs) showed the maximum color change, whereas the compomer showed a slightly significant color change. In acetic acid all the test materials showed color changes, ie maximum by glass ionomers (GIs), followed by compomers (Polyacid modified composites- PMCs) & resin modified glass ionomers (RMGls). I0% hydrogen peroxide solution resulted in degradation and high degree of color change for chemical­cured GIs. The light cured resin-modified Glass Ionomers (RMGIs) and compomers (PMC'S) showed high color change in 10% hydrogen peroxide solution. The light-cured composite (RBC-control), showed insignificant color change in all the experimental solutions.
