The aim of this study was to investigate and compare fluoride release of giomer (Beautifil Injectable), compomer (Dyract® XP), and composite resin (Filtek™ Z350XT) through adhesive (Scotchbond Multi-Purpose) layer. A total of 20 cylindrical specimens (7 mm in diameter and 2 mm in thickness) of giomer, compomer and composite resin were prepared according to the manufacturers’ instruction (10 with adhesive and 10 without adhesive). These specimens were immersed individually in 2 mL of deionized water at 37℃. The amount of fluoride release was measured on the 1st, 3rd, 7th, 14th, 21st, and 28th day. To confirm uniform application of the adhesive layer, additional 18 specimens with adhesive were prepared and evaluated by scanning electron microscope. The giomer and compomer groups with adhesive applied showed no fluoride release until the 3rd day. However, from the 7th day, fluoride was detected. The application of dentin adhesive did not completely prevent fluoride release from giomer or compomer. Fluoride release was significantly (p < 0.05) reduced through the adhesive layer. The reduction of fluoride release was more remarkable on the giomer.
