Sažetak:
Background and purpose: Topical application of fluoride onto the dental enamel surface mainly induces the formation of alkali-soluble fluoride, described as a calcium fluoride or calcium fluoride-like material (CaF2). It is believed that calcium fluoride acts as a pH-controlled fluoride-releasing reservoir. The aim of this study was to quantify, in vitro, the formation of alkali-soluble fluoride after application of an amine fluoride solution with different fluoride content and different frequency of use, on the human dental enamel. Material and methods: Four enamel slabs were cut from 11 impacted third molars and randomly divided into four groups. One of them served as the unfluoridated control (D). Each of three groups of slabs were shaken for 3 min in an amine fluoride solution of different fluoride concentration with pH of 3.8 ; group A: 1% F twice a day ; group B: 0.5% F three times a day and group C: 0.25% F four times a day. The treatments were repeated during three consecutive days. The formation of the alkali-soluble fluoride was analysed chemically. Results: The amount of alkali-soluble fluoride (ľg/cm2ąSD) was significantly higher in group C (115.77ą59.98) than in groups A (56.17ą48.95) and B (71.69ą37.03). No significant difference (p>0.05) was found between the A and B groups. The amount of alkali-soluble fluoride on the enamel increased with the time of exposure despite the lower content of fluoride. Conclusion: The results show that increased frequency of fluoride applications even with a lower fluoride content may result in the formation of more calcium fluoride.
