Abstract

In this research, Mechanical and biological properties of the commercial dental cement (Fuji II LC Improved, GC America) was investigated by adding Titania nano fibers. The surface of these fibers was functionalized using a bi-functional monomer, methacrylic acid. Then, the mechanical properties of TiO2–GICs were investigated with different Titania concentrations. GC Fuji II LC acted as standards for comparison. Results showed that the mechanical properties generally increased with increasing the amount of TiO2 nano particles until 5 wt.%. Based on the determined mechanical properties, the optimized composition was found at 1 wt.% n-TiO2 fibers, which provided a signiﬁcant increase in KIC (73%), FS (42%) and FM (56%). However the biocompatibility were not different from the control.
