Objective was to evaluate the color stability of modern resin composites designed for esthetic anterior restorations when continuously exposed to various staining agents. Six disc-shaped specimens were made of each of twelve composite materials. After dry storage at 37°C for 24 h in an incubator (INP-500, Memmert), initial color of each specimen was assessed by a calibrated reflectance spectrophotometer (SpectroShade). Specimens were then divided in 6 groups and immersed in 5 staining solutions or dry stored (control). All specimens were kept in an incubator at 37°C for 99 days. Test solutions were changed every 14th day to avoid bacteria or yeast contamination. After 99 days of storage spectrophotometric measurements have been again performed and L*a*b* scores once more recorded to determine the color changes. Composite resin materials, staining solutions and their interactions were statistically significant. There was strong interaction between stain and material. Color of esthetic restorations can be maintained over a longer period of time in the oral environment either by introducing some restrictions to patient's dietary habits of or carefully choosing the type of material that is best compatible with their dietary lifestyle.
