[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. That was predominantly fluorine of drinking water. Mathematical formula for calculation of fluorine content in the food cooked for feeding of infants was elaborated. A computer program was formed be means of which calculation, control and management of fluorine intake are carried out in feeding alteration.

[Problems of fluoride dosing to infants for dental fluorosis prevention].

Fluoride content in drinking water, breast milk, cow milk, additional food for newborns prepared with water containing different amount of fluoride was determined. Fluoride excretion in urine since the first days of birth and up to 4 months of postnatal development was investigated in breast and artificially fed infants. When a neonate was fed with breast milk, fluoride was received in the amount no more than 20 mkg/day. The additional food contained fluoride which water mainly had. Water with high level of fluorine increased its content in the additional food up to the values not comparable to those in breast milk that presented danger of dental fluorosis development. Data on fluorine content in drinking water were absolutely necessary to calculate daily fluorides consumption by infants and to prevent dental fluorosis.

[Fluoride content in potable water and drinks. Connection with dental caries prevention and dental fluorosis].

Content of fluoride by ion selective electrode in potable water (municipal water supply, bottled, from draw-wells and springs), in juices of industrial and compotes of domestic preparation, in drinks of various grades of the tea made by water with unequal contents of fluorine was analyzed. Fluoride entered organism of the population in non-control mode more often in minimum quantities that explained, in certain measures a wide caries incidence. Granting of the information upon concentration of fluorides in potable water, juices and drinks used by population would allow people to adjust this microelement intake in the organism with the purpose of preventing of dental caries and fluorosis.
