title: Influence of chosen elements on the dynamics of the cariogenic process.
abstract: This prospective study comprised 140 natural crowns of the teeth extracted from 31 boys and 35 men, as well as 39 girls and 35 women. They were divided into two groups. Group I consisted of primary teeth and group II consisted of permanent teeth. In each group, two subgroups were distinguished: subgroup A containing teeth without caries and subgroup B comprising carietic teeth. Zinc, iron, copper, nickel, chromium, cobalt, lead, cadmium, selenium, and strontium were determined in the samples by using the total reflection X-ray fluorescence method. Significantly higher concentrations of zinc, iron, copper, nickel, selenium, and strontium were detected in the crowns of healthy primary and permanent teeth than in the crowns of the carietic primary and permanent teeth. The concentrations of chromium, cobalt, lead, and cadmium were significantly higher in primary and permanent teeth with caries than in the healthy ones. Judging from the obtained results, we think that lower concentrations of zinc, iron, copper, nickel, selenium, and strontium together with higher concentrations of chromium, cobalt, lead, and cadmium in the carietic primary and permanent teeth, in relation with the respective concentrations of those elements in healthy teeth, can be one of the caries risk factors.
