本实验利用体外细胞培养技术,观察人牙龈成纤维细胞在不同处理,尤其是Fn处理后的根面上附着的形态。结果表明,在龈面脱矿的基础上应用Fn处理根面,可以明显促进细胞的附着与扩展。而单独应用枸橼酸根面脱矿处理或单独应用Fn进行根面处理,则无明显地促进细胞附着及扩展的作用。 In this study, in vitro cell culture technique was used to observe the morphology of human gingival fibroblasts attached to the root surface after different treatments, especially Fn treatment. The results showed that application of Fn to the root surface on the basis of gingival demineralization can obviously promote the attachment and expansion of cells. However, citrate root demineralization alone or root application of Fn alone did not significantly promote cell attachment and expansion.
