[Trace element studies on the the dental calculi of individuals from historical populations].

In two different populations (Bavaria 6th-7th cent. A.D. and Egypt 700 B.C. till 400 A.D.) calculus was analysed in order to find hints for the nutrition of these people. All together, the concentration of 23 elements were analysed. The first dates showed that there were high significant differences in 8 elements (Al, Ba, Ca, Cr, Fe, K, Mn, Sr). The enormous variation of the element concentration as well as the huge of elements allows finally interpretations not in this state. It will be the aim of further studies.
