Determination of Fluorine Ions Penetration Degree Into Enamel by Empa.

Abstract

Exogen of different preparations was applied to completely healthy teeth of children up to 11 years. A month after application of fluorine, teeth were extracted and prepared by standard methods for investigation by electron microprobe ARL, type SEMQ. The results obtained showed that the highest degree of fluorine ions migration was stimulated by organic fluorite' (amin fluoride). Very poor results were obtained by NaF, while the values obtained by 'fluor-protector' ranges between these two preparates. All up to date investigations showed that protective characteristics of fluorine against caries formation were reached only in case when enamel surface contained fluorine concentration of 10**3, mu g. Thus, our results proved that the first condition for good prophylaxy is obtained by application of aminofluoride and then by 'fluor-protector'.
