Abstract :Aims: This in vitro study aimed to evaluate the effect of commonly prescribed pediatric iron supplements-ferric polymaltose (Ferrum®) and ferrous sulfate (Ferro Sanol B®)-on the color stability (ΔE) of different restorative materials. Methods: One hundred eighty specimens from composite resin, compomer, flowable composite resin, and glass ionomer cement were assigned to distilled water (control), ferric polymaltose, or ferrous sulfate groups (n=15). All samples were stored at 37°C, immersed in the test solutions for 2 minutes daily, and evaluated at baseline, 7 days, and 28 days. Between immersions, specimens were kept in distilled water. Color measurements were performed using a spectrophotometer (VITA Easyshade, Germany) in the CIE Lab* system and ΔE values were calculated. Data were analyzed using Kruskal-Wallis and Mann-Whitney U tests (p<0.05). Results: Both iron supplements caused significant discoloration in all restorative materials compared to the control (p<0.05). GIC exhibited the highest color change, while composite resin showed the lowest. Ferric polymaltose produced greater discoloration than ferrous sulfate in most material groups, particularly in GIC. Conclusion: Pediatric iron supplements have a high potential for discoloration of restorative materials, with the iron’s chemical form influencing the extent of staining. The development of formulations with reduced staining potential may contribute to improved esthetic outcomes in pediatric dental care.
