新型复合弓丝抗变形链球菌粘附的研究
|
Abstract:
摘要 目的:采用荧光显微镜和扫描电镜,观察激光焊接加铜中间层镍钛-不锈钢复合弓丝(Composite Arch wire,CAW)的抗变形链球菌粘附作用。方法:将未与变形链球菌共培养的镍钛弓丝、不锈钢弓丝、复合弓丝及铜丝组分别作为空白对照组;将与变形链球菌共培养的镍钛弓丝、不锈钢弓丝、复合弓丝及铜丝组分别作为实验组,经共培养48 h,进行荧光显微镜与扫描电镜观察。结果:实验组与空白对照组经荧光显微镜观察,显示复合弓丝组加铜中间层处与铜丝表面均呈红色荧光区;扫描电镜观察显示实验组复合弓丝组加铜中间层处与铜丝细菌粘附均少于镍钛弓丝、不锈钢弓丝及复合弓丝的镍钛侧及不锈钢侧;且变形链球菌形态出现溶解与破碎现象。 结论:复合弓丝组加铜中间层处对变形链球菌具有一定的抗粘附作用
