Résumé
Des dents saines ont été traitées de façon exogène par différents produits fluorés. Le fluor a ensuite été analysé par sonde électronique. Les résultats montrent que la meilleure prophylaxie des caries est assurée par des composés fluorés organiques plutôt que minéraux.
Abstract
Exogen application of different preparations was done at completely healthy teeth of children up to 11 years. A month after application of fluorine, the relative teeth were extracted and the same were prepared by stamdard 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 103, µg. Thus, our results undoubtedly proved the fact that the first condition for good prophylaxy is obtained by application of aminofluoride and then by "fluor-protector".
