Comparative evaluation of fluoride release profiles in new glass ionomer cements and conventional type II GIC: Implications for cariostatic efficacy

Abstract

The fluoride release characteristics of two new Glass Ionomer Cements (GICs), Equia Forte HT and Micron Bioactive, with a conventional Type II restorative GIC is of interest. Fluoride release, a crucial cariostatic property, was evaluated using 18 disc specimens prepared in disposable silicone molds and stored in deionized water for 15 days. Measurements taken on days 1, 3, 7 and 14 with a fluoride ion-specific electrode showed that Equia Forte HT exhibited the highest fluoride release, followed by Micron Bioactive and Type II GIC. Statistical analysis, including ANOVA, confirmed significant differences among the groups, highlighting the superior performance of Equia Forte HT. These findings emphasize the importance of selecting GICs with optimal fluoride release for effective dental restorations and call for further research into their long-term clinical performance.
