The aim of this study was to find out if cigarette smoking influences the Cd, Cr, Cu, Fe, Mn, Pb, Zn, K, Na, Ca and Mg contents and mutual relationships between these elements in teeth. The content of elements was determined by means of atomic absorption spectrometry in the smokers' and non-smokers' teeth. It was concluded that the cigarette smoking results in the significant increase of Cd, Zn and Cu contents in teeth and that the supply of heavy metals from cigarette smoke to human organism influences the mutual relationships between the elements in a tooth structure.
