The aim of this study was to determine the effect of different surface conditioning techniques on the bond strength between zirconia-reinforced lithium silicate (ZLS) ceramics and resin cement.
Fifty samples of ZLS ceramic were used and allotted into five groups with 10 samples per group based on the type of surface conditioning technique. The ceramic specimens were crystallized and embedded into acrylic resin. The five groups were group 1 (negative control-without surface treatment); group 2 (10% hydrofluoric [HF] acid + silanization); group 3 (10% HF acid only); group 4 (self-etching ceramic primer [SECP]); and group 5 (experimental laboratory sealing of the conditioned surface). Resin cylinders were bonded using self-adhesive resin cement and were subjected to thermocycling after 24 h storage. The shear bond strength was tested with a universal testing machine.
One-way ANOVA was used for comparing five groups ( < 0.05 was considered significant).
Group 4 showed the highest mean bond strength value (23.4 MPa ± 2.21 MPa). A statistically significant difference was noted between group 4 and all the other groups tested in the study ( < 0.05).
It can be concluded that the SECP can be considered an alternative to the conventional protocol of HF acid and silane application for the surface conditioning of ZLS ceramic.
本研究旨在确定不同表面处理技术对氧化锆增强硅酸锂（ZLS）陶瓷与树脂水门汀之间粘结强度的影响。
使用50个ZLS陶瓷样本，根据表面处理技术类型将其分为五组，每组10个样本。将陶瓷试件结晶并嵌入丙烯酸树脂中。五组分别为：第1组（阴性对照 - 未进行表面处理）；第2组（10%氢氟酸[HF] + 硅烷化）；第3组（仅10%氢氟酸）；第4组（自酸蚀陶瓷底漆[SECP]）；第5组（对处理后的表面进行实验性实验室封闭）。使用自粘结树脂水门汀粘结树脂圆柱体，并在储存24小时后进行热循环处理。用万能试验机测试剪切粘结强度。
采用单因素方差分析比较五组（P < 0.05被认为具有统计学意义）。
第4组显示出最高的平均粘结强度值（23.4 MPa ± 2.21 MPa）。在第4组与本研究中测试的所有其他组之间观察到统计学上的显著差异（P < 0.05）。
可以得出结论，对于ZLS陶瓷的表面处理，SECP可被视为传统氢氟酸和硅烷应用方案的替代方法。
