将钛片随机分成光滑组、双重酸蚀喷砂组、氢氟酸酸蚀喷砂组、微弧氧化组，分别进行不同表面处理。将小鼠成纤维细胞接种于不同钛片表面，MTT 法检测成纤维细胞在不同钛片表面的黏附和增殖情况，并在培养24 h 后利用扫描电子显微镜观察成纤维细胞在试件表面的铺展形态。结果显示细胞黏附情况存在差异（P <0.05），光滑组<氢氟酸酸蚀喷砂组<双重酸蚀喷砂组<微弧氧化组；细胞增殖测试中，微弧氧化组在各时间点都显著高于另外3组。相较其他3种表面处理方法，成纤维细胞能够在经微弧氧化处理的试件表面更好地黏附、增殖。

Titanium plates were randomly divided into four groups,each with different surface treatments(smooth group,double acid corrosion sandblasting group,HF acid etching sandblasting group,microarc oxidation group). Mouse fibroblast cells were inoculated on different groups of titanium plates and tested by MTT to detect cells′ adhe-sion and proliferation. Cells were cultured for 24h and observed on the surface of plates by scanning electron micro-scope. The comparison between the rates of fibroblasts′ adhesion was smooth group < HF acid etching sandblasting group < double acid corrosion sandblasting group < microarc oxidation group(P < 0. 05). Fibroblasts′ proliferation was higher than on microarc oxidation group than those on the other three groups. Compared with the other three kinds of surface treatment,fibroblasts can be on the specimen surface treated by microarc oxidation better adhesion and proliferation.
