Abstract

The purpose of this study was to examine an effect of fluoride recharging on fluoride release and surface change of fluoride-releasing restorative materials. Six commercially available fluoride releasing restorative materials (Fuji II LC Improved: FL, Compoglass F: CF, Dyract AP: DA, F2000: FT, Gradia Direct: GD, and Tetric Ceram: TC) were selected as experimental materials. Disk specimens were fabricated with split teflon mold to the final dimensions of 15 mm in diameter and 1 mm in thickness. Ten samples of each material were fabricated and stored in deionized water at $37^{\circ}C{\pm}1^{\circ}C$ for 3 months. Before fluoride recharging, all specimens were polished sequentially from #800 to #2000 emery papers. Fluoride recharging was done at 5-day interval using 2.0% NaF gel. The release of fluoride into the storage water was monitored using a fluoride ion electrode. Data were analyzed by one-way ANOVA and Tukey's multiple range test. The results obtained were summarized as follows; 1. Fluoride recharge capability were FL > CF > DA and TC group after 12 times exposure to 2.0% NaF gel (P<0.05). 2. All the experimental materials, except for FT group, showed the increase of fluoride release and surface roughness. 3. Fluoride-releasing rates returned to base line within 3 days.
