Justifi cation of the choice of fluoride preparations for prophylaxis of caries in milk teeth
The aim of the study is to reveal the dependence of the choice of fl uoride preparations for prophylaxis of caries in milk teeth. on the biochemical and microbiological indices of saliva, which determine the development of a cariesogenic condition in the oral cavity (concentration of calcium and phosphorus in saliva, a level of lactobacteria and pH) in 120 children at the age of 3 to 5, residents in the area with low content of fl uorine in water (N.Novgorod). "Tiefenfl uorid " was the most eff ective fl uoride preparation, when the level of lactobacteria was above normal, the level of pH was below normal and the concentration of calcium and phosphorus in saliva was normal. "Gluft ored" was the most eff ective fl uoride preparation, when the concentration of calcium and phosphorus in saliva was below normal. "Bifl uorid 12" in this study showed the intermediate results at all indices.
