The effect of commonly used pediatric iron supplements on the color stability of restorative materials

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
