持久的树脂-陶瓷粘附可能会影响陶瓷修复体的临床成功，这一直是牙科领域的挑战性问题之一。本研究通过拉伸粘合强度测试、表面元素组成和 X 射线光电子能谱评估了 10-甲基丙烯酰氧基癸基磷酸二氢盐 (MDP)、MDP+硅烷和 MDP-盐底漆与喷氧化铝氧化锆陶瓷的粘合强度和化学相互作用。分析、接触角测量、扫描电子显微镜的表面形态和 3 维共焦激光扫描显微镜分析的表面形貌。与 MDP 和 MDP+硅烷相比，MDP-盐在热循环前后的拉伸粘合强度最高（P  < 0.05）。测得的接触角值差异显着（P < 0.001) 的顺序为 MDP-盐 > 对照（无化学预处理）> MDP+硅烷 > MDP。所有测试组之间的表面粗糙度（P  = 0.317）和表面形貌没有差异。用 MDP 盐处理的氧化锆除了氧化锆和氧化铝峰外还显示出磷峰。MDP 盐具有氧化锆底漆性能，可提高与树脂水泥的粘合性能。

Durable resin-ceramic adhesion may influence the clinical success of ceramic restorations, which has been one of the challenging issues in dentistry. The present study assessed the bond strength and chemical interaction of 10-methacryloxydecyl dihydrogen phosphate (MDP), MDP+silane, and MDP-salt primers to alumina-blasted zirconia ceramic by tensile bond strength test, surface elemental composition with x-ray photoelectron spectroscopy analysis, contact angle measurement, surface morphology with scanning electron microscopy, and surface topography with 3-dimensional confocal laser scanning microscope analyses. MDP-salt showed the highest tensile bond strength before and after thermocycling when compared with MDP and MDP+silane (P  MDP+silane > MDP. There was no difference in surface roughness (P = 0.317) and surface topography among all tested groups. Zirconia treated with MDP-salt showed phosphorus peaks in addition to zirconia and alumina peaks. MDP-salt has zirconia priming properties, which improves bonding performance to resin cement.
