Iron drops are often prescribed to children less than 2 years of age. Due to their low pH, these drops may soften the enamel and accelerate its destruction. The present study aimed to evaluate the enamel hardness of deciduous teeth after being exposed to various iron drops.

A total of 48 healthy deciduous anterior teeth were randomly assigned to four groups (n=12 in each group). The samples were exposed to three drops of Sideral iron, Ferrosomal, and Ferrous sulfate for 5 min. Surface hardness was measured before and after iron drop exposure. Four groups were exposed to HCL, and the obtained data were analyzed using the least significant difference (LSD) test and analysis of variance (ANOVA).

In all groups, a decrease was observed in the surface hardness of surface enamel. In the Sideral group, the average initial hardness was 358.81, the secondary hardness was 337.23, and the tertiary hardness was 221.19. In the Ferosomal group, the average primary hardness was 375.67, the secondary hardness was 336.80, and the tertiary hardness was 208.23. In the Ferrous sulfate group, the average initial hardness was 383.41, the secondary hardness was 301.73, and the tertiary hardness was 149.13. Therefore, the three groups statistically differ before and after the iron drop. After the use of iron drop in an acidic environment, there was a statistical difference between Ferrous sulfate and two other drops (P<0.05). Between Sideral and Ferosmal, the difference was not significant (P=0.864).

As evidenced by the results of this study, it can be concluded that all three types of iron droplets in the environment, similar to human saliva, significantly reduced the hardness of enamel. In an acidic environment, all three types of iron drop reduced the hardness of the enamel of deciduous teeth. The Ferrous sulfate group demonstrated the most significant reduction in the microhardness of the enamel, and the Sideral group had the most negligible decrease in enamel hardness.

  Iron excretion increases during sport activities and menstruation. However, consumption iron supplements along with vitamin C improves iron stores. The purpose of this study was to investigate the effect of aerobic training, consumption of iron, and vitamin C on blood iron indices among females with iron deficiency and with at least six months sport activities background. In this semi-experimental study, 32 volunteer females aged 35±4. 4 years were selected and randomly divided into four groups including a control group and three training groups (T1: without supplements; T2: + iron; T3: + iron + vitamin C). The training program consisted of eight weeks ،three sessions per week and 60 minutes per session (jogging, low impact aerobic training chain) with an intensity of 70% of the target heart rate. After per session of exercise in T2 and T3 groups subjects consumed 100 mg pill of ferrous sulfate and in T3 group subjects consumed 500 mg chewable vitamin C pill. Before and after the research protocol, blood hemoglobin, hematocrit, red blood cell, ferritin and transferrin measured by using specific methods. Multivariate analysis of variance was used. The results showed differences in the hemoglobin, hematocrit, red blood cell, ferritin and transferrin variables between T3 and control group which were significant for hemoglobin (p=. 006), red blood cell (p=. 008), and ferritin (p=. 003) variables. Aerobic training with consuming iron supplementation and vitamin C can improve some hematological indices in females.
