[Risk and prevention of teeth fluorosis in infants by feeding pattern changes].

Effect of fluorides in drinking water on fluorine content in breast milk, the food for infants of the 1-sty year of life, was investigated. On determining fluorine concentration in urine and its excretion, fluorine intake by the infants was calculated under various alternatives (breast, mixed and artificial) of feeding. It has been found the in mixed and especially in artificial feeding, fluorine intake by the infants acquires uncontrollable character exceeding several times the dose of fluorine intake with breast milk under natural feeding.

[Infra-red spectrometry in oral liquid study for diagnostic purposes].

Infra-red (IR) spectrometry of the saliva was done by means of specially developed hardware-software complex. It was established, that in 9 wide ranges of the IR-spectrum there were diverse fluctuations of transmittance that characterize intermolecular interactions of various molecules associated with water and metabolites of biological systems. The found fluctuations were characterized quantitatively by dispersion of transmittance coefficients.
