Aim: To determine the mineral composition of enamel and dentin of temporary and permanent teeth of children in the mountain zone of the Transcarpathian region and to conduct a comparative analysis of the obtained indicators. Materials and Methods: 25 temporary and 25 permanent teeth were subjected to research. The conditions of selection were the absence of carious lesions. The study was carried out by the method of raster electron spectrometry. Results: In children who permanently live in the mountainous geographical zone of the Transcarpathian region, the mineral composition of enamel and dentin was determined by spectrometry and the following probable differences were established: the carbon content in the enamel of temporary teeth is probably higher compared to the content in the enamel of permanent teeth and in dentin; the content of oxygen, phosphorus, calcium, sodium, magnesium and chlorine in permanent teeth is probably lower in relation to the content in permanent teeth in enamel and dentin (p<0.05). Conclusions: The accumulation of chemical elements in the teeth is considered a good indicator of qualitative changes in the diet and water supply of the population. The peculiarities of the mineral composition of the hard tissues of the temporary teeth of children who have lived for a long time in the mountainous zone of the Transcarpathian region, namely the presence of sulfur, confirm the fact that the hard tissues of the teeth, especially the temporary ones, are a detector of the state of the ecological environment.
