Iron uptake (Fe2+ and Fe3+) by bones, teeth, and dental enamel was studied, in vivo and in vitro, by chemical, powder X-ray diffraction and Mossbauer spectroscopy methods. Atomic absorption tests have revealed the permanent uptake of small amounts of iron by dental enamel soaked in vitro in solutions containing Fe2+. Mossbauer spectra show that the iron attached to the dental enamel stays at the same valency it had in the soaking solutions. Mossbauer measurements of in vivo samples show that iron is present in bones and teeth mainly as Fe3+ (10% Fe2+ in teeth), in compound similar to FeOOH. Iron is released or exchanged from teeth at a much lower rate than from bones.
采用化学、粉末X射线衍射和穆斯堡尔光谱法，在体内和体外研究了骨骼、牙齿及牙釉质对铁（Fe2+和Fe3+）的摄取情况。原子吸收测试表明，浸泡在含Fe2+溶液中的牙釉质会持续摄取少量铁。穆斯堡尔光谱显示，附着在牙釉质上的铁保持其在浸泡溶液中的相同价态。对体内样本的穆斯堡尔测量表明，铁在骨骼和牙齿中主要以Fe3+形式存在（牙齿中10%为Fe2+），其化合物类似于FeOOH。铁从牙齿中释放或交换的速率远低于从骨骼中释放或交换的速率。
