Fluoride releasing and uptake capacities of esthetic restorations.

Background And Objectives: The purpose of this study was to evaluate and compare in vitro the fuoride release and uptake from 5 different esthetic restorative materials.

Materials And Methods: Materials tested were conventional GIC - Fuji 7, GC (group1), resin modifed GIC - Vitremer, 3M ESPE (group 2), polyacid modifed composite - Dyract, Dentsply (group 3), fuoride releasing composite - Tetric ceram, Ivoclar Vivadent (group 4), Giomer-Beautifl, Shofu (group 5). Fluoride release was estimated at 6th, 24th, 48th hour and weekly interval for 5 weeks.
