In vitro cytotoxicity test of three dental restorative material
Objective: To compare the cytotoxicity of three kinds of dental restorative material, nano-composite resin Filtek Z350, compomer Dyract- AP and traditional composite resin TPH on human pulp cell in vitro. Methods: Human pulp cell were cultured by tissue culture from fresh dental pulp, the effect of each material on viability of human pulp cell was measured by MTT assay. The adherence of human pulp cell to different material surface was observed under scanning electron microscope (SEM). Results: The Filtek Z350 nano-composite resin showed the least cytotoxicity among three kinds of material tested (P<0.05). Under SEM observation, pulp cells showed good adherence to all three kinds of material. Conclusion: All these three kinds of dental restorative material were biologically safe. Among them the cytotoxicity of Filtek Z350 nano-composite resin was the least. (This research was funded by Fujian Province Natural Science Grant Z0516035).
