Comparative evaluation of the mechanical properties of a bioactive material enhanced by phytosynthesized nanoparticles: An In vitro study
Aims: The aim was the study was to evaluate and compare the mechanical properties of ACTIVA Bioactive Base/Liner (ABBL) enhanced with phytosynthesized titanium dioxide nanoparticles (nTiO2) and nano-curcumin (nCur). Methodology: Thirty samples each of ABBL (Group 1), ABBL + nTiO2 (Group 2), and ABBL...

| Summary: | Aims: The aim was the study was to evaluate and compare the mechanical properties of ACTIVA Bioactive Base/Liner (ABBL) enhanced with phytosynthesized titanium dioxide nanoparticles (nTiO2) and nano-curcumin (nCur). Methodology: Thirty samples each of ABBL (Group 1), ABBL + nTiO2 (Group 2), and ABBL + nCur (Group 3) were prepared for testing the compressive strength (CS) and flexural strength (FS). Forty-five cylinders (15 per group) (6 mm × 4 mm) were fabricated for CS and 45 for three-point bending FS measurements (22 mm × 2 mm × 2 mm). They were tested in a universal testing machine at a crosshead speed of 0.5 mm/min for CS and 0.5 mm/min with 20 mm space between the two supports for FS measurements. Statistical Analysis: Intergroup comparison of CS and FS was assessed using one-way ANOVA. The level of significance was set at 0.05. Results: Intergroup comparison showed an overall significant difference (P = 0.016 for CS) and (P = 0.001 for FS), where Group 1 had the highest and Gr 3 the least strength. No significant difference was observed between Group 1 and Group 2, while Group 3 showed significantly low strength when compared to Group 1. Conclusions: ABBL + 3% nTiO2 showed nonsignificant decrease while ABBL + 7% nCur showed significant decrease in mechanical properties. |
