Abstract
The article is about the peculiarities of trace elements balance in 6-year-old children living in Bukovina. The following observation groups were selected: Group I – 69 children suffering from caries, and Group II – 26 dentally healthy children. In order to determine stable indicators accumulated over a long period of time, we analyzed children's hair for Fe, Cu, Zn and Mg content by atomic absorption spectrophotometry. The degree of probability of the obtained results was statistically assessed. As a result of our research, in the hair of children with caries, it was found that copper and zinc were probably lower, by 24.93% and 77.93%, respectively, compared to dentally healthy children, which negatively affects the processes of mineralization and contributes to the demineralization of teeth. The level of iron and magnesium was 33.43% and 59.83% higher in children with dental caries. We determined the content of trace elements depending on the intensity of caries damage to the teeth: the highest values of copper, zinc and iron – under the conditions of a low level of caries intensity, the lowest – under the conditions of a very high level. Magnesium concentration increased with an increase in the number of cariously affected teeth. While determining the ratio of essential trace elements in the hair of children with caries and dentally healthy children, an imbalance in their values was determined. Thus, the Zn/Cu ratio in the hair of children with caries was 46 times higher compared to this indicator in dentally healthy children. The remaining indicators indicate that the ratio in children with caries is lower: Cu/Fe – by 34.37%, Zn/Fe – by 6.76 times, Fe/Mg – by 1.65 times, Cu/ Mg – 2.73 times. So, we have established an imbalance in the micronutrient supply system for children with caries, which indicates the need for its correction during the development of therapeutic and preventive measures. Keywords: caries, magnesium, iron, zinc, copper.
