The evaluation of the influence of ionizing radiation on the processes of dissolution in tooth enamel in model experiments may be useful for the optimization of the methods for prophylaxis of radiation caries. The objective of the present study was to study the solubility of tooth enamel in a variety of media following its in vivo and in vitro treatment with ionizing radiation. The following characteristics were measured to determine changes in the composition and properties of aqueous media: pH, electric conductivity, dissolved calcium level, and optical density. The samples for the measurement of Ca and P concentrations in enamel biopsies were selected by the method of V.K. Leontiev. The results of the study indicate that in vivo effects of ionizing radiation and acidic reaction of the medium increase solubility of hard tooth tissues which leads to a shift in the processes of remineralization and demineralization towards the predominance of the latter.
