Cribra orbitalia and trace element content in human teeth from Neolithic and Early Bronze Age graves in southern Poland.

Determination of element levels in bones and teeth can complement knowledge of the diagnostics and etiology of various diseases in prehistoric populations. Calcium (Ca), cadmium (Cd), copper (Cu), iron (Fe), and lead (Pb) content were analyzed in teeth from human skeletons dated to 3,000-1,400 BC from Malopolska Upland loess. Levels of iron and calcium were determined using atomic absorption spectroscopy (AAS), and lead, cadmium, and copper levels were measured using anodic stripping voltametry (ASV). Molar teeth from specimens with cribra orbitalia were selected for analyses, and teeth from specimens with no pathological changes were used as a control. No significant correlations between the content of particular elements and the tooth class, specimen age, or depth of burial pit were observed. The Fe content in specimens with cribra orbitalia is not the best measure for this disease's etiology. Thus, interelement correlations and proportions might give a better picture of the biological condition of the specimen and of the investigated groups.
