Notes:
In this study, CaSiO3 (CS)/Ca3(PO4)2 (TCP) composites with 50% CS and 50% TCPsintered at different temperatures (1100oC, 1200oC and 1300oC) were prepared. The formation ofbone-like apatite on CS-TCP composites was investigated by soaking the ceramics in simulatedbody fluid (SBF), and the presence of bone-like apatite layer on the composite surface after soakingin SBF was determined by X-ray diffraction (XRD) and field emission scanning electronmicroscopy (FESEM). The results showed that the bone-like apatite was formed on all the CS-TCPcomposites sintered at different temperatures after 7 days of immersion. In addition, the degradationof CS-TCP composites prepared at different temperatures was evaluated by measurement of weightloss of the ceramics in Tris-HCl buffer solution at 37oC, and the results showed that there was nodifference in degradation rate between the samples. In vitro cell experiments indicated that theosteoblasts proliferated faster on the CS-TCP ceramics sintered at higher temperature, and cells onthe CS-TCP ceramics sintered at 1300oC showed highest proliferation rate. These results providevaluable information for designing CS-TCP composite bioceramics for bone regenerationapplications
