“…It was found that the distribution of Zn and Cu in enamel and dentin of rats with acute Cd supply as well as of controls was the same as found previously in rats, 11 human deciduous teeth 23 and human permanent teeth. 45 The distribution of Pb in enamel and dentin was in agreement with that found previously in rats 11 45 but not those found in human deciduous teeth.…”

Eleven groups of Wistar rats were given 5 ppm cadmium acetate in the drinking water at different and interrupted periods of their life (in utero, during sucking etc.), simulating acute exposure. The Zn, Cu and Pb levels of indicators (teeth and hair) and target organs (soft tissues and bone) were recorded by atomic absorption spectrophotometry. It was concluded that acute exposure to Cd has a somewhat different effect on Zn, Cu and Pb storage in the tissues than chronic exposure. It was further inferred that the effects on Zn, Cu and Pb cannot be used as diagnostic criteria in population screenings at very low doses of Cd.

“…When the Zn and Cu contents of the fossil teeth are compared with those of modern, ideally fed laboratory rats, the recorded levels may well represent those existing in the living animals [9,13,27]. At least there has been no influx of these elements during fossilization; if anything has changed postmortem, there must have been a slight leaching of the elements.…”

Sectioned Cretaceous mammalian teeth were studied by light microscopy and SEM equipment with an electron microprobe. Structures resembling odontoblast processes were found. Their S/Fe ratio was similar to that of rat odontoblast processes, but the amounts of these elements were far higher than in processes of recent teeth. It was concluded that they consisted of pyrite, but their reaction with mercurochrome indicated presence of proteins with SH groups. Fluorescence microscopy indicated traces of collagen in the dentin. In the fossil enamel and dentin the Ca/P ratio was similar to that of recent teeth. Two samples of fossil teeth were analyzed for Pb, Cd, Zn, and Cu content by atomic absorption spectrophotometry. The levels of the latter two elements were normal, whereas that of Cd and especially that of Pb were higher than in laboratory rats. The probability that original protein fractions exist and that the different elements were those of the living animals is discussed.

“…Several heavy elements have been shown to be pfesent in human primary teeth, among them lead, cadmium, zinc, and copper (2)(3)(4)13). Lead is probably the best-known metal where primary teeth have been used as indicators for undue exposure (3)(4)(5)(6)(7)(8).…”

“…No such increase of cadmium had occurred (2,4). It was also found that the preindustriai zinc supply was uniform and sufficient but that this might not be the case in many modern rural districts in Norway (4,13).…”

Seventy‐nine primary (deciduous) teeth were excavated in 1978 underneath the floor of the stave church in Uvdal, Buskerud County, Norway. The mercury content of 57 teeth was measured by means of cold vapor atomic absorption spectrophotometry. As a comparison, 124 primary teeth from modern Norway were analyzed. A significant statistical difference was found between the two sets of material. In the Uvdal material a correlation was found between the mercury and copper contents. For the modern material a correlation was found between mercury and lead, and between mercury and zinc. The authors maintain that the values found for the Uvdal material represent base‐line values for mercury in primary teeth, and probably reflect uptake from natural environmental sources only. Furthermore, these values may be used for reference in studies of other preindustrial, as well as modern, primary teeth. Our findings also indicate a higher level of mercury in modern than in preindustrial primary teeth in Norway.
