Abstract
Objectives: To perform a comparison between ACTIVA BioACTIVE restorative, Nano-filled dental composite and RMGIC for compressive and flexural strength. Materials and methods: A total of 60 specimens were made of (ACTIVA Bioactive-, Filtek Z350XT and Ketac Nano-100 RMGI), thirty specimens were prepared for compressive strength testing and the other 30 specimens were prepared for flexural strength testing using two split Teflon molds with different dimensions. All specimens were kept in distilled water for 24 h, then they were tested by universal testing machine. Results: The Filtek Z350XT recorded the highest values for compressive and flexural strength, while the lowest values were for Ketac Nano-100. There was no statistically significant difference between compressive strength values of Filtek Z350XT and ACTIVA. While there were significant difference among flexural strength values for all the materials. Conclusion: ACTIVA demonstrates mechanical properties comparable to dental composite and superior to traditional RMGIC.
