Abstract
Aim: This study was assumed to investigate the effect of incorporation of nanoparticles “Titanium Dioxide Nanoparticles (TiO2)” in two different percentages which are 3% and 5% (by weight) on compressive strength and surface roughness of glass ionomer cement (GIC) so to improve the conventional glass ionomer cement properties. Materials and Methods: the powder of GIC was incorporated with TiO2 nanoparticles at two concentrations: 3% and 5% (w/w). An unmodified conventional GIC used as the control group. Ten specimens of each GIC group were used to study the compressive strength using a Universal Testing Machine. Also, 10 discs from each GIC group were used for surface roughness measurement by using profilometer. one way analysis of variance ANOVA test and Tukey’s test were used to analyze data. Results: Nanoparticles incorporation to GIC lead to improve its compressive strength for both percentages 3% and 5%, Tukey’s test showed a significant increase in compressive strength between nanoparticles incorporated and conventional group. The surface roughness measurement also show significantly improvement in both 3% and 5% nanoparticles groups (p<0.05). Conclusion: GIC with TiO2 nanoparticles.
