The concentrations of 12 different elements were measured in dentin and enamel of primary and permanent teeth collected in six different localities in Finland. Na, Cl, Al, Mn, Ca, and P were determined by neutron activation analysis, K, Mg, Zn, Cu, and Fe by the atomic absorption method, and F with the fluoride-specific electrode. Most elements were present in higher concentrations in the enamel than in the dentin: Mg, however, was higher in the dentin. Compared with the permanent teeth, the primary teeth contained more K and Mn in enamel and K and Mg in dentin, but less Na and Zn in enamel. Differences between the six localities were significant for F, Cl, K, Zn, Na, and Mn. Fe, Cu, and Mn contents of teeth were much lower in Finland than elsewhere; in the typical Finnish diet the contents of Fe and Cu are relatively low and iron deficiency anemia is usually common in Finland.
在芬兰六个不同地区收集的乳牙和恒牙的牙本质和牙釉质中，测量了12种不同元素的浓度。钠、氯、铝、锰、钙和磷通过中子活化分析测定，钾、镁、锌、铜和铁通过原子吸收法测定，氟通过氟特异性电极测定。大多数元素在牙釉质中的浓度高于牙本质：然而，镁在牙本质中的含量更高。与恒牙相比，乳牙的牙釉质中钾和锰含量更多，牙本质中钾和镁含量更多，但牙釉质中钠和锌含量更少。六个地区之间在氟、氯、钾、锌、钠和锰方面存在显著差异。芬兰牙齿中的铁、铜和锰含量比其他地方低得多；在典型的芬兰饮食中，铁和铜的含量相对较低，缺铁性贫血在芬兰通常很常见。
