OBJECTIVE: To evaluate the effects of exposure to various children's drinks on the color stability of different esthetic restorative material commonly used in pediatric dentistry. STUDY DESIGN: Cylindrical specimens (15 x 2mm) were prepared from four different restorative materials (Fuji IX, Fuji II LC, Dyract Extra, and Filtek Z250). For each material, 20 specimens were prepared and divided into four groups. Each group was stored in a different solution (distilled water chocolate milk, cola, grape juice) for 24 hours. A colorimeter was used to measure the color of each specimen both before and after staining. Color change (deltaE*) was calculated, and data was analyzed using two-way ANOVA and Tukey HSD tests. RESULTS: For all restorative materials, the lowest deltaE* values were recorded for specimens stored in distilled water (0.42), followed by chocolate milk (0.88), grape juice (3.45) and cola (3.97). Among the four restorative materials tested, Fuji II LC showed the most color change (3.71) and Fuji IX the least (1.33). There were statistically significant differences among above groups (p < 0.05). CONCLUSIONS: DeltaE* values were acceptable for all materials tested, with the exception of Fuji II LC. Therefore, the use of RMGIC should be avoided in anterior restorations in children due to esthetic reasons.
