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