Effect of Antibiotic, Multivitamin and Iron Preparations on Color Stability of Pediatric Restorative Materials: An In Vitro Study

Background/Objectives: This in vitro study compared the color stability of four pediatric restorative materials after exposure to three pediatric liquid medications in a 4 × 3 factorial design.

Methods

Sixty disc specimens (10.0 × 2.0 mm) were prepared from a composite resin (Charisma Smart), a compomer (Nova Compomer), a giomer (Beautifil Kids SA), and a high-viscosity glass ionomer cement (HVGIC; Equia Forte HT with Equia Forte Coat) (n = 15 per material) and allocated to antibiotic, multivitamin syrup, and iron preparation subgroups (n = 5); the specimens were immersed for 2 min twice daily for 7 days. ΔE00 values were calculated from VITA Easyshade V measurements at baseline and after exposure and were analyzed using two-way ANOVA with Bonferroni-adjusted comparisons.
