本研究旨在评估紫外线照射和He等离子体处理氧化锆盘是否可增强其与人牙龈成纤维细胞（HGFs）的生物相容性，并比较两种方法的差异。 制备氧化锆盘并分成三组：UVC光处理（组UV），He等离子体（组P）和对照组。分析三组氧化锆盘的表面形态，润湿性。评估培养的HGF的粘附密度，形态，增殖和胶原合成。结果显示，UV光和等离子体处理之后，接触角减小。在每个时间点，HGF在P组中的粘附和增殖最高（p <

本研究旨在评估紫外线照射和He等离子体处理氧化锆盘是否可增强其与人牙龈成纤维细胞（HGFs）的生物相容性，并比较两种方法的差异。

制备氧化锆盘并分成三组：UVC光处理（组UV），He等离子体（组P）和对照组。分析三组氧化锆盘的表面形态，润湿性。评估培养的HGF的粘附密度，形态，增殖和胶原合成。

结果显示，UV光和等离子体处理之后，接触角减小。在每个时间点，HGF在P组中的粘附和增殖最高（p <0.05）。 P组的HGF在3天和7天后Col-1的表达水平也最高。

总之，该研究结果表明，光滑氧化锆经等离子体和紫外光处理改善了其表面的亲水性，而等离子体处理对细胞粘附，增殖，尤其是胶原合成的作用更大。
