Aim: To compare and evaluate the mechanical properties of 2.5% titanium dioxide nanoparticle (TiO2 NP) incorporated as filler in an experimental composite resin with everX Flow and MultiCore Flow.
Materials and methods: TiO2 was prepared and incorporated into experimental dental composite resin. The experimental and traditional composite resin was grouped as follows: Group I: The experimental composite resin with 2.5% of TiO2 fillers, Group II: everX Flow (GC EUROPE), and Group III: MultiCore Flow (Ivoclar Vivadent). Based on International Standards Organization (ISO) 4049, the samples were prepared for the compressive, diametral tensile, and flexural test.
Results: Statistical analysis was done, and the results were tabulated. Compared to the other tested materials, the experimental composite resin had relatively high compressive strength, diametral tensile strength, and flexural strength. Compared to MultiCore Flow, the everX Flow showed strong mechanical properties.
Conclusion: Based on the result of the study, it can be concluded that the 2.5% TiO2 NP incorporated as filler in an experimental composite resin demonstrated higher mechanical properties compared to the conventional material.
Clinical significance: The unique photoactivities of TiO2 NP and their superior mechanical properties make them one of the ideal additives to enhance the performance of polymeric materials.
