Abstract

Aim: To evaluate the biological and mechanical properties of an adhesive with nanostructured silver vanadate (AgVO₃). Materials & methods: Specimens in poly(methyl methacrylate) (PMMA) were treated with Ultra Corega Cream (UCCA) denture adhesive with or without AgVO₃. Biofilms of Candida albicans, Candida glabrata and Streptococcus mutans were grown and the viable cells counted. Fluorescence microscopy was used. The viability of the VERO cell and adhesive strength were evaluated. Results: All concentrations of AgVO₃ reduced the biofilm formation and showed no cytotoxic effect. At 5 min and 24 h, UCCA with 5 and 10% AgVO₃ showed better performance, respectively. Conclusion: AgVO₃ promoted the antibiofilm activity of the adhesive, with a positive effect on the adhesive strength, and was biocompatible.

钒酸银对义齿粘合剂抗生物膜、粘附性和生物相容性的影响

目的：评估纳米结构钒酸银（AgVO3）粘合剂的生物和机械特性。材料与方法：使用含或不含 AgVO3 的 Ultra Corega Cream (UCCA) 义齿粘合剂处理聚甲基丙烯酸甲酯（PMMA）试样。培养白色念珠菌、光滑念珠菌和变异链球菌的生物膜，并对存活细胞进行计数。使用荧光显微镜观察。对 VERO 细胞的存活率和粘合强度进行了评估。结果：所有浓度的 AgVO3 都能减少生物膜的形成，且无细胞毒性作用。在 5 分钟和 24 小时内，含有 5%和 10%AgVO3的 UCCA 分别显示出更好的性能。结论AgVO3 提高了粘合剂的抗生物膜活性，对粘合强度有积极影响，而且具有生物相容性。
