Abstract
The goal of this research was to explore how incorporation of Titanium Dioxide Nanoparticles (Tio2/NPS) at two different concentrations 3% and 5% (w/w) may affect the mechanical and physical characteristics of glass ionomer cement (GIC). Methods: Titanium Dioxide Nanoparticles (TiO2 /NPS) were incorporate at 3% and 5% (w/w) into the powder component of glass ionomer cement. As a control, unblended powder was use. A universal testing machine was use to estimate flexural strength, a Vickers micro hardness tester was used to determine surface micro hardness, and water solubility and sorption were measured according to the ISO standard. ANOVA and the Tukey test have been use to evaluate the data. Results: GIC with 3% and 5% (w/w) TiO2 nanoparticles increased surface micro hardness, with the Tukey test revealing a significant difference in micro hardness between groups. While flexural strength showed no statistical differences (p>.0001) and no significant increase in flexural strength among the investigated groups. Water sorption and solubility exhibited statistical differences (p<.0001), with a substantial reduction of water solubility and water sorption among the investigated groups. Conclusions: GIC containing 3% and 5% (w/w) TiO2 nanoparticles can be considered a viable restorative material with improved mechanical properties.
