English Abstract
Background and Objectives: The aim of this study was to measure the water sorption (WS), water solubility (SO) and depth of cure (DC) of modified microhybrid composite resins by adding 2 types of nanofillers in two concentration 3% and 5% and comparing them to unmodified microhybrid composite resins and to nanofilled composite resin.
Methods: For water sorption (WS) and solubility (SO), ten disk-shaped specimens of each resin composite were made for each group and stored in desiccators until constant mass was achieved.
Specimens were then stored in water for 7 days, and the mass of each specimen was measured.
The specimens were dried again and weighed.
The WS and SO were calculated from these measurements.
For depth of cure test ten metal moulds with 6 mm long and 4 mm in diameter were prepared then filled with the tested materials.
After irradiation, the uncured material gently removed, and measured by micrometer.
Data analyzed by one-way ANOVA.
Results: The results showed there were significant differences among the groups in the WS mean values which ranged from 10.05 to 20.69 μm/ mm³, while the SO mean values were ranged from 0.2727 to5.8765 μm/ mm³.
The results of depth of cure showed significance differences among the groups and mean value ranged from 0.99500 to 1.9325 mm.
Conclusion: The addition of ZnO to microhybrid composite increased the WS and SO values and decreased the depth of cure values compared to the control group, while the addition of CaCO3 to microhybrid composite had no significant effect on the SO and DC values but they significantly increases the WS compared to the control.
