The purpose of this study was to examine the effect of amounts of resin components on fracture toughness of experimental glass ionomer cement for filling. The experimental glass ionomer cements were prepared by adding Bis-GMA/TEGDMA to a commercially available glass ionomer cement for filling (Fuji Ionomer Type II) up to 40% of cement liquid. The fracture toughness values (K_<IC>) of the experimental cements were determined at 24 hours after cement mixing by the notchless triangular prism (NTP) method reported by Ruse et al. The results suggested that the addition of resin components increased the fracture toughness values where the resin components contained 20% into the cement liquid under the present experimental condition.
