ABSTRACT:
This study evaluated the mechanical properties of glass ionomer cement (GIC) incorporated with different concentrations (0.5%, 1.0%, 2.0%, 5.0% by wt.) of L-Arginine nanoparticles. GIC powder was mixed with various concentrations of L-Arginine and mixed with its corresponding polyacrylic acid and a total of 150 specimens were made. The specimens were divided into 3 groups for evaluating compressive strength, shear bond strength and microhardness, with 50 in each. The fifty specimens from each group were further divided into 5 subgroups with 10(n=10) in each, based on the concentrations of nanoparticles. The shear bond strength samples were tested on the universal testing machine, The load was applied at a crosshead speed of 0.5 mm/minute until the specimen was debonded from the tooth. Compressive strength the sample was placed on the compression grip of the universal testing machine and the load was applied at a crosshead speed of 0.5 mm per minute until the specimen fractured. The microhardness of the specimen was measured using the Vickers Hardness Tester. The data obtained were subjected to statistical analysis using one-way ANOVA and Tukey’s test. GIC modified with 0.5% L-Arginine demonstrated high Shear bond strength (6.76±0.89 MPa), Compressive strength (117.11±24.8 MPa), and Vickers hardness (67.46±4.51VHN) compared to the other modified and control groups. One-way ANOVA showed significant differences (p<0.001) in SBS, CS, and SH among the groups. The addition of 0.5wt% L-Arginine into glass ionomer cement demonstrated an increase in the shear bond strength, compressive strength, and Vickers hardness.
