Adsorption Rate of Iron onto Primary Incisor Teeth Following the Application of Three Iron Drops

Background & Aims: Iron deficiency anemia is the most common kind of anemia in childhood. Iron supplements that are usually prescribed for the treatment stain teeth. The purpose of this study was an in vitro comparison of the adsorption rate of iron onto incisor primary teeth after exposure to three different Iron drops (Darupakhash, Fer–In– Sol, Shahredaru). Methods: This study was performed on sixty intact primary incisor teeth in two stages with one week interval. In each stage thirty teeth were examined. The teeth in each stage were divided into three groups and each group was exposed to one kind of Iron drop. The rate of Iron adsorption was measured by Atomic Absorption system. ANOVA (Kruskal – wallis) test was used for statistical analysis. Results: There was a significant difference among three types of Iron drops in adsorption of Iron (P<0.001). Fer–In–Sol had the least and darupakhash had the highest adsorption rate. Conclusion: Although all three Iron drops cause stain on primary incisor teeth, there is a significant difference among them
