Abstract

Background and objectives

The purpose of this study was to evaluate and compare in vitro the fluoride release and uptake from 5 different esthetic restorative materials.

Materials and methods

Materials tested were conventional GIC — Fuji 7, GC (group1), resin modified GIC — Vitremer, 3M ESPE (group 2), polyacid modified composite — Dyract, Dentsply (group 3), fluoride releasing composite — Tetric ceram, Ivoclar Vivadent (group 4), Giomer-Beautifil, Shofu (group 5). Fluoride release was estimated at 6th, 24th, 48th hour and weekly interval for 5 weeks. For fluoride recharge, each specimen was exposed to 2 ml of 1.23% APF gel for 4 minutes and fluoride release measured at 1st, 2nd, 3rd day and 7th day. The fluoride release and recharge was measured using fluoride ion specific electrode.

Results

ANOVA and Tukey HSD test were used for statistical analysis. During tested period all materials showed statistically different capability to release and uptake fluoride. Groups 1 and 2 results were comparable in fluoride release. Similarly groups 3 and 5. Groups 1 and 2 vs 3, 4, 5 were statistically very highly significant. Only conventional GIC showed initial ‘burst effect’.

Interpretation and conclusion

Materials tested showed potential for fluoride release and recharge. Different esthetic materials had variable fluoride release hence selection of materials should be guided by specific clinical situations.
