The impact of adding nano zirconium dioxide fillers on color change, water sorption and solubility for denture liners

Objective: Zirconium dioxide (ZrO2) nanofillers were added to denture liners improve their physical properties. The main goal of this research was evaluate the impact adding nano zirconium oxide fillers on color change, water sorption and solubility silicone acrylic liners. Materials Method: surface ZrO2 nanoparticles modified via treatment with silane coupling agent (3-aminopropyl) triethoxysilane. Fourier transform infrared spectroscopy analysis performed characterize surfaces untreated or treated ZrO2. After modification, these incorporated into Three subgroups assigned for each test method. Kruskal-Wallis Mann-Whitney U tests used statistical (p ? 0.05). Results: Water in values decreased addition nanofiller both groups (respectively, acrylic-based tissue conditioner: p = 0.040 0.020; silicone-based liner: < 0.001 0.017). conditioner group 1% showed greatest change (?? 37.94 ±6.62), whereas liner 0.5% presented lowest 5.02 ±2.30). Conclusion: Modified nanofiller–incorporated might show better clinical success than ones according evaluated parameters.
