The occurrence of copper in deciduous teeth of girls and boys living in Upper Silesian Industry Region (Southern Poland).

This work presents the results of a research concerning the copper content in different types of deciduous teeth (incisor, canine, molar) of boys and girls living in the Upper Silesian Industry Region (Southern Poland). The average copper concentration in deciduous teeth was 9.92 microg/g and was significantly higher in the deciduous teeth of boys (12.24 microg/g) in comparison to the deciduous teeth of girls (8.60 microg/g). The concentration of copper was statistically variable depending on the type of tooth (incisor, canine, molar). The results of the correlation analysis and cluster analysis indicate mainly the participation of lead, iron, manganese and chromium ions in the formation of copper content in hard tissue of deciduous teeth.
