目的：为了防止食物残渣和牙菌斑在义齿表面堆积，研究人员开发了几种亲疏水方法。在这项研究中，我们评估了开发一种高功能自清洁义齿的可能性。材料与方法：义齿基托树脂标本根据表面处理类型分为：对照组（未处理）；亲水性（紫外线照射或摩擦化学涂层）；和疏水（等离子体化学气相沉积，CVD）。表面分析采用x射线光电子能谱、傅里叶变换红外能谱和原子力显微镜进行。使用三点弯曲试验评估物理强度。数据分析采用单因素方差分析和多重比较。结果：亲水性处理的自清洁效果不理想；CVD样品的疏水性、力学性能和自清洁能力均显著提高（p < 0.05）。结论：疏水表面改性在不影响树脂力学性能的前提下，有效地提高了树脂的拒水性能。[J] .中国科学（英文版）；2019;19:1-8。
Purpose: Several hydrophilic and hydrophobic approaches have been developed to prevent food debris and plaque accumulation on the denture surface. In this study, we evaluated the possibility of developing a high-functioning self-cleaning denture. Materials and Methods: Denture base resin specimens were divided into the following groups based on the type of surface treatment: control (no treatment); hydrophilic (UV irradiation or tribochemical coating); and hydrophobic (plasma chemical vapor deposition, CVD). Surface analyses were conducted using X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and atomic force microscopy. Physical strength was evaluated using the three point bending test. Data were analyzed using one-way analysis of variance followed by multiple comparisons. Results: The self-cleaning effects of the hydrophilic treatments were unsatisfactory; alternatively, the hydrophobicity, mechanical properties, and self-cleansing ability of the CVD specimens were significantly high (p < 0.05). Conclusion: Hydrophobic surface modifications effectively improved the water repelling properties of the resin without compromising its mechanical properties. (Asian Pac J Dent 2019; 19: 1-8.)
