One of the main ecological problems of mankind is the quality of drinking water, which directly affects the health of the population. Dental health undoubtedly depends on the essential composition of drinking water.

The aim. To evaluate the trace element composition of drinking water and to determine the role of trace elements of water origin in the prevalence of caries among children in the Chernivtsi region.

Materials and methods. We analyzed Regional Reports on the state of the environment in the Chernivtsi region in 2021, 2020, and 2019, and we also took samples of drinking water in 13 schools in the region, where dental examinations of schoolchildren were conducted. Chemical and analytical studies of water samples were carried out at the Ukrainian Scientific Center for Marine Ecology.

Results. The waters of the rivers of the Chernivtsi region are classified as “slightly polluted”, compared to previous years, there is a tendency to improve the quality of drinking water intakes on the Prut and Siret rivers.

As for the macroelemental composition of drinking water, the calcium content did not exceed the maximum permissible concentrations only in the Prut River, in the village of Herts. In the rest of the regions, there is an increase in calcium concentration from 59.1 to 124 mg/l, which indicates increased water hardness. The magnesium content was within the permissible values and ranged from 5.02 to 49.8 mg/l.

Trace elements such as zinc, iron and copper were within the limits of permissible values and their amount depended on the region. Fluorine deserves special attention, since its concentration was normal only in two samples from the Prut River and the Syret River.

Samples from the Dniester River have an average fluoride content, from the Cheremosh River in the lower reaches – a low fluoride content, from the Cheremosh River in the upper reaches – extremely low.

Conclusions. The investigated concentrations of micro- and macroelements indicate the poor quality of drinking water from the Dniester and Cheremosh rivers for maintaining the dental health of children in the Chernivtsi region.

Keywords: drinking water, Bukovyna rivers, fluoride, dental health.
