In-vitro study evaluates enamel microhardness in primary teeth after iron supplement exposure, indicating no significant effect.

This study aims to evaluate the effect of four types of iron supplements on the microhardness of deciduous tooth enamel.
In-vitro study with 55 anterior primary teeth divided into five groups (one control and four experimental).
Microhardness measured using a Vickers hardness tester before and after exposure to iron supplements.
Statistical analysis conducted using One-way ANOVA to compare groups.
No statistically significant differences in enamel microhardness changes among the groups (p > 0.05).
Mean microhardness changes were: control 68.82 ± 68.13, Amivital Ferrous Sulphate 32.06 ± 34.61, SiderAl 84.45 ± 97.20, Liposofer 30.35 ± 20.48, and Feramax 58.58 ± 70.27.

Vahedi et al. (2026) studied this question.
