Abstract

Background: The purpose of this study was to analyze the anti-adherent activity of nano-coatings deposited by Thermionic Vacuum Arc plasma on C. albicans ATCC 10231 biofilm.

Materials and methods: A total of 80 disc-shaped (2 × 10 mm) polymethymethacrylate samples were prepared and divided into four groups with 10 samples in each group (Control, ZnO, SnO₂, Ag) (n = 10). Using thermionic vacuum arc plasma, they were coated with ZnO, SnO₂, and Ag. 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and Crystal Viole (CV) assays were conducted for biofilm quantification. Scanning electron microscopy (SEM) was used to observe biofilm images of C. albicans biofilm.

Results: MTT and CV mean values differ statistically significantly between all groups (p ⩽ 0.05). The SnO₂ group had the lowest mean value, whereas the control group received the highest value.

Conclusion: SnO₂ coating shown greater anti-adherent activity than either metal oxides. C. albicans biofilm formation on denture base surfaces is reduced following Thermionic Vacuum Arc plasma coating with SnO₂.

热离子真空电弧等离子体沉积纳米涂层对白色念珠菌生物膜的抗粘附活性。

背景:研究热离子真空电弧等离子体沉积纳米涂层在白色念珠菌ATCC 10231生物膜上的抗粘附活性。材料与方法:制备80个圆盘状(2 × 10 mm)聚甲基丙烯酸甲酯样品，分为4组(Control, ZnO, SnO2, Ag)，每组10个样品(n = 10)。采用热离子真空电弧等离子体对其进行ZnO、SnO2和Ag包覆。3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四唑(MTT)和结晶紫(CV)测定生物膜的定量。采用扫描电镜(SEM)观察白色念珠菌生物膜的生物膜图像。结果:各组间MTT、CV均值差异有统计学意义(p < 0.05)。SnO2组的平均值最低，对照组的平均值最高。结论:SnO2涂层具有较强的抗粘附活性。SnO2热离子真空电弧等离子体涂层可减少义齿基托表面白色念珠菌生物膜的形成。
