Abstract

Background and objective: The aim of the present study was to evaluate certain mechanical properties of flowable dental composite after incorporation of Titanium dioxide nanoparticles (TiO2NPs).

Materials and Methods: In the present study, TiO2NPs at 1.25 % and 2.5% concentrations were added to flowable dental composite, while the unmodified composite was used as control. Then the mechanical properties of the control and modified composite resins, including Vickers microhardness, Flexural strength and Fracture toughness were tested. Data were analyzed with One way ANOVA, using SPSS version 20.0

Results: The results showed that there was statistically significant difference among the tested groups regarding Vickers microhardness, Flexural strength and Fracture toughness (P<0.05). In addition, there was a significant difference among control group and TiO2NPs modified groups regarding Flexural strength in which 2.5% group showed a significant reduction in flexural strength in comparision with 1.25% and control groups.

Conclusion: Based on the results of the present study, a flowable dental composite was successfully reinforced with TiO2NPs. Incorporation of small weight percentages of this nanofiller exhibited properties better than control material.
