Abstract

Background and Aims: Metallic nano-particles show exclusive biological, chemical and physical characteristic.The purpose of this research was to evaluate the effect of various amounts of nanosilver incorporation (0 (as control), 20, 40, 80, 120, 200 ppm) on the mechanical Properties (compressive and flexural strength) of resin modified GLASS IONOMER CEMENT.Materials and Methods: Based on ISO 4049 and ISO 9971 for polyalkenoid CEMENTs, 90 cases in each group were prepared for the flexural and COMPRESSIVE STRENGTH. Specimens in 6 groups with different amounts of nanosilver (20, 40, 80, 120 and 200 ppm) and control (Fuji II LC improved), stored in distilled water at 37oC for 1 day and 30 days. Flexural strength, using a three-point bending method, Modulus of elasticity and the COMPRESSIVE STRENGTH were measured by universal testing machine (Zwick) with crosshead speed of 0.5 mm/min. Data were analyzed using two-way ANOVA and Tukey post HOC test.Results: The flexural strength and modulus of various amounts of nanosilver incorporation of resin modified glass-ionomer CEMENT were not significantly different (P>0.05). The COMPRESSIVE STRENGTH of incorporating of 20 ppm compared with control (P=0.01), 40 ppm (P=0.02) and 80 ppm compared with control (P<0.001) were increased. The flexural strength and COMPRESSIVE STRENGTH of Fuji II LC, containing nanosilver particles were increased after 1 day and 1 month significantly (P<0.001).Conclusion: Incorporation of 20 to 80 ppm nanosilver into Fuji II LC had increased mechanical properties compared to the original CEMENT.
