Iron and magnesium, indispensable elements for human life, are also trace elements in tooth minerals. They have been implicated in the early stages of caries. Iron, an indispensable element for human life, forming for example, the core of hemoglobin molecules [1] is also a trace element in tooth minerals [2]. Iron accumulates in the outer surface of tooth enamel [2]. Analyses of total enamel have shown considerable variation in the iron content of individual human teeth, probably related to differences in iron ingestion and age. However, the form in which iron is deposited in the enamel and the mechanism of its acquisition are still not fully understood. Francis et al. [3] reported that Fe ions are effective in reducing the subsequent acid dissolution rate of enamel. This result seems to be related to the incorporation of Fe2+ ions into apatite crystals.
