Dent Mater J:等离子体和紫外线处理氧化锆可增强其生物相容性

2020-02-14 不详 网络

本研究旨在评估紫外线辐射和氦等离子体处理氧化锆圆片是否增强了其与人牙龈成纤维细胞(HGFs)的生物相容性,并比较了这两种方法的区别。 研究人员制备了氧化锆盘,并将其分为三组:UVC光处理(UV组),He血浆(P组)和对照组。分析氧化锆圆盘的表面形态,润湿性。测量了培养的HGF的粘附密度,形态,增殖和胶原合成。结果显示, 经过紫外线和等离子处理后,氧化锆圆盘的接触角减小。P组中HGF的粘附和增殖在每

本研究旨在评估紫外线辐射和氦等离子体处理氧化锆圆片是否增强了其与人牙龈成纤维细胞(HGFs)的生物相容性,并比较了这两种方法的区别。

研究人员制备了氧化锆盘,并将其分为三组:UVC光处理(UV组),He血浆(P组)和对照组。分析氧化锆圆盘的表面形态,润湿性。测量了培养的HGF的粘附密度,形态,增殖和胶原合成。

结果显示, 经过紫外线和等离子处理后,氧化锆圆盘的接触角减小。P组中HGF的粘附和增殖在每个时间点最高(p <0.05)。 P组的HGF在3天和7天后也释放了最高水平的Col-1。

综上所述,该研究结果表明,等离子体和紫外线对光滑氧化锆的处理以不同的机理改善了表面的亲水性,而氦等离子体对细胞的粘附,增殖,尤其是胶原合成具有更好的作用。
