To evaluate the effect of universal adhesives on the long-term bond strength to yttria-stabilized tetragonal zirconia polycrystal (Y-TZP).
Polyethylene tubes filled with composite cement containing 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) were adhesively luted to 60 fully sintered Y-TZP slabs (7 x 7 x 2 mm) with or without (control) previous application of a 10-MDP-based adhesive (All Bond Universal, Bisco) - ABU; Clearfil Universal Bond Quick, Kuraray Noritake - CUB; Scotchbond Universal Adhesive, 3M Oral Care - SUA) on the zirconia surface. The bonded specimens were stored in water for 24 h, 6 months, or 1 year and subjected to microshear bond strength testing. The data were analyzed by one-way ANOVA and Tukey's test (p < 0.05). The contact angle was measured after adhesive application to evaluate surface wettability. The adhesive-treated specimens were analyzed with x-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) for chemical characterization.
The application of a 10-MDP-based adhesive significantly improved bond strength of composite cement to zirconia when compared to the control group (no adhesive application) (p < 0.05). One-year water storage significantly decreased bond strength for ABU- and CUB-bonded specimens, but not for SUA-bonded specimens. The analysis by XPS and ToF-SIMS showed peaks of carbon, phosphorus, and silicon in all adhesive-treated specimens.
One-year water storage affected the bond strength of composite cement to zirconia when All Bond Universal or Clearfil Universal Bond Quick were used.
评价通用粘结剂对氧化钇稳定四方氧化锆多晶（Y-TZP）长期粘结强度的影响。
将含有 10-甲氧基丙烯酰氧基癸基二氢磷酸酯（10-MDP）的复合水泥填充的聚乙烯管以粘结剂的形式粘接到 60 个完全烧结的 Y-TZP 平板（7 x 7 x 2 mm）上，其中一些（实验组）在氧化锆表面预先应用了基于 10-MDP 的粘结剂（All Bond Universal，Bisco - ABU；Clearfil Universal Bond Quick，Kuraray Noritake - CUB；Scotchbond Universal Adhesive，3M Oral Care - SUA），另一些（对照组）则没有应用粘结剂。将粘结后的试件在水中储存 24 h、6 个月或 1 年，然后进行微剪切粘结强度测试。通过单向方差分析和 Tukey 检验（p < 0.05）对数据进行分析。在应用粘结剂后测量接触角，以评估表面润湿性。用 X 射线光电子能谱（XPS）和飞行时间二次离子质谱（ToF-SIMS）对经粘结剂处理的试件进行化学特性分析。
与对照组（未应用粘结剂）相比，应用基于 10-MDP 的粘结剂显著提高了复合水泥对氧化锆的粘结强度（p < 0.05）。1 年水储存显著降低了 ABU 和 CUB 粘结试件的粘结强度，但对 SUA 粘结试件的粘结强度没有影响。XPS 和 ToF-SIMS 分析表明，所有经粘结剂处理的试件中均出现了碳、磷和硅的峰。
当使用 All Bond Universal 或 Clearfil Universal Bond Quick 时，1 年水储存会影响复合水泥对氧化锆的粘结强度。
