Aim and objective: The current research aimed to appraise the color stability of two different tooth-colored restorative materials employed in primary teeth. Materials and methods: Ninety primary molar teeth that were extracted for various therapeutic reasons were included in the current study. Class V cavity preparation was done on the buccal surface of these 90 primary molar teeth. Depending on the type of restorative supply used, the molar teeth were randomly allocated to one of the two equivalent groups (n = 45) that is group I received nanocomposite resin while group II had resin-modified glass ionomer cement (RMGIC) restoration. Rehydration after cavity preparation was achieved by keeping the samples in distilled water for 1 day. Following rehydration, these samples were washed and dried up with filter paper, and the baseline color quantification was performed. After the same, the above group samples were immersed for 10 minutes each day in three dissimilar but routinely used children\'s beverages that are an aerated beverage, ice candy, chocolate milk, and Bournvita milk. The color disparity of each sample was quantified with a reflectance spectrophotometer. Results: Nanocomposite resin (4.28 ± 0.02 to 11.04 ± 0.18) portrayed less resistance to color variation in contrast to RMGIC (4.74 ± 0.53 to 8.12 ± 0.12) following immersion in the aerated beverage. Following dipping in the ice candy, nanocomposite resin (4.46 ± 0.61 to 9.98 ± 0.42) depicted higher shade change in comparison to RMGIC (4.89 ± 0.22 to 6.30 ± 0.09). Following the immersion in chocolate milk and Bournvita milk, RMGIC (4.60 ± 0.20 to 5.96 ± 0.29) found trivial color variation as judged against nanocomposite resin (4.96 ± 0.01 to 8.68 ± 0.16). Conclusion: The present study concluded that the color stability of the RMGIC group showed higher resistance to staining as compared to nanocomposite resin with all beverages used in this study. Clinical significance: Children drink and eat foods that are bright and colorful. These substances contain food additives that can blemish not only the natural teeth but also the restorations. As esthetics and appearance are of foremost significance for both parents and their children, the prolonged color steadiness of restorative supplies is of extreme significance.
