Effects of different iron preparations on the color stability of restorative materials: an in vitro study

Year: 2026

Type: article

Abstract: PURPOSE: This in vitro study aimed to evaluate the effects of different iron preparations on the color stability of two restorative materials. METHODS: Two restorative materials, a compomer (Dyract XP) and a universal composite resin (Filtek Z250), were evaluated. Ninety-six disc-shaped specimens (8 mm × 2 mm) were prepared and divided into four subgroups according to the iron preparation used (Bestiron, Ocean Microfer, Fermix, and Ferrum) (n = 12). Specimens were immersed daily for 2 min over 28 days. Color differences (ΔE₀₀) were calculated using the CIEDE2000 formula. Data were analyzed using two-way ANOVA (p < 0.05). RESULTS: The effects of restorative material, iron preparation, and their interaction on color change were significant (p < 0.001). The lowest ΔE₀₀ was observed in Ocean Microfer-compomer (0.75 ± 0.40), whereas the highest values were found in Bestiron-compomer (4.54 ± 1.52) and Fermix-compomer (4.29 ± 1.45). Only the Ocean Microfer compomer and Ocean Microfer composite groups remained within the clinical acceptability threshold (ΔE₀₀ ≤ 1.8). CONCLUSION: Both restorative material type and iron preparation affected color stability. Among the iron preparations evaluated in this study, Ocean Microfer remained below the clinical acceptability threshold in both restorative materials.
