| Abstract: | Objective To evaluate the cytotoxicity of four types of native carbon fiber-reinforced post materials(polyimide,PI). Methods The viability and proliferation of L-929 cells were tested by MTT assay. Relative growth rates of cells were calculated and the cytotoxicities were graded by generally accepted standard. Results Relative growth rates of PI1-4 were more than 75% and increased gradually. The cytotoxicity of PI1-4 was grade 1. Conclusion The four types of native carbon fiber-reinforced post materials have no evident cytotoxicity,and PI4 has the best cytocompatibility. |
