The purpose of this study was to evaluate the properties related to the strength and resistance to abrasion of new Type II lightcured glass ionomers, VariGlass VLC, and Fuji L.C., and to compare the results with Ketac-Silver and Z-100 composite resin. Each material was tested for strength with an Instron Universal Testing Machine and for resistance to abrasion with a motor-driven machine. The strengths of Z-100 were the highest. Among glass ionomers, Ketac-Silver had higher compressive strength, but lower diametral tensile and transverse strengths than the others; and Fuji II L.C. had higher strengths than VariGlass VLC. VariGlass VLC showed the greatest resistance to abrasion, followed respectively by Z-100, Fuji II L.C. and Ketac-Silver. ANOVA indicated significant differences in strengths and abrasion resistance, except, the volume losses of Fuji II L.C. and Ketac-Silver in the toothbrushing test were not significantly different (p < 0.01). The results support VariGlass VLC and Fuji II L.C. as alternative filling materials in Class III and V situations, but they are not recommended for stress-bearing restorations.
