Abstract
The aim of the study was to correlate Fe, Cu, Zn, Pb, Br, Sr and Mo concentrations in human teeth crown, root and bone. The samples, teeth from a lower jaw bone and the lower jaw bone itself, were obtained post mortem from a woman 97 years old; 200 mg of crown and root of the teeth, and lower jaw bones were fixed to a Kapton film and irradiated with a 3.8-MeV external proton beam from an 8-MV FN Tandem Van de Graaff Accelerator. The F-test was used to analyse the differences among crown, root and bone. For Fe, Zn and Pb, the comparison showed significant differences among the 3 sample populations of tooth crown, root and bone; for Cu, Br, Sr and Mo, the comparison showed no significant differences among the sample populations. Several elements in the samples were highly interrelated.
