The Effect of Some Common Children’s Drinks on Color Stability of Nanocomposite and Nanoglass Ionomer

The purpose of this study was to evaluate the effect of some common children’s drinks on color stability of nanocomposite and nanoglass ionomer. A hundred test specimens of two restorative materials (Filtek Z350; 3M and Ketac N100; 3M wereprepared using a Teflon mold (8x2 mm). Baseline measurements of color and surface roughness of each specimen were made and specimens (n=10) were immersed in 5 groups: G1: orange juice, G2: guava juice, G3: Strawberry milk; G4: Chocolate milk, and G5: Distilled water (control. Final measurements of color and surface roughness were performed and the results submitted to statistical analysis (2-way ANOVA, p<0.05). Their was no statisically significant difference between mean color change for both materials and the most significant color change was observed for specimenswhen immersed in orange juice (p<0.05). With regard to roughness, nanoglass ionomer showed the most significant changes when immersed in orange juice (p<0.05). It was concluded that color changes were dependent on the immersion media rather than the material used while surface roughness was dependent on both material type andimmersion media.
