Abstract

Objective To determine the enamel fluoride retention after application with fluoride gel. Materials and methods Fourteen subjects, aged between 20-22 years old, were included. The buccal enamel biopsies were conducted on the middle buccal surfaces of the upper premolar before and at 30 minutes, 2, 4 and 8 weeks after 1.23% acidulated phosphate fluoride application. Fluoride concentration of the etching solution was determined using a fluoride electrode. Calcium concentration was evaluated by an atomic absorption spectrophotometer. The data were analyzed by Wilcoxon Signed Rank test and Friedman test at significant level .05. Results The baseline value of enamel fluoride content was 2,107±498 ppm. After the application with fluoride gel at 30 minutes, 2, 4 and 8 weeks the fluoride content were 6,525±699, 4,751±966, 2,906±663 and 1,792±466 ppm, respectively. Statistical analysis revealed a significant increase in the enamel fluoride content at 30 minutes, 2 and 4 weeks when compared to the baseline value (p < .01). No significant difference between the 8 weeks value and the baseline was observed. Conclusion The enamel fluoride retention after topical application with acidulated phosphate fluoride gel lasts for more than 4 weeks but no longer than 8 weeks.
