Abstract | AIM: The aim of this study was to evaluate the three-body wear-resistance of one type of restorative glass-ionomer cement (GIC). MATERIALS AND METHODS: Specimen including conventional GIC (Ionofil Molar AC Quick: IMACQ), hybrid ionomer ( Fuji II LC), and composite resin ( Heliomolar) were tested in a wearing machine. In this machine, a 6 kg load was applied via pressable chromium- cobalt bar at 5,000, 10,000, 20,000, 40,000, 80,000, 120,000 cycles. Specimen weight was measured by an electronical weight balance before and after each cycle. Data were analyzed using one-way analysis of variance (ANOVA) followed by a t-test, and a paired t-test at P≤0.05. RESULTS: CONCLUSION: The wear rate of GIC IMACQ was between those of heliomolar composite and Fuji II LC glass ionomer in all cycles except 120,000 cycles. The most important advantage of this new-generation glass ionomer is its good manipulability and also high wear-resistance compared to the hybrid ionomer. Therefore, it is suggested that it can be used as restorative material in class I restorations in primary teeth.
