To use shear bond strength (SBS) and shear fatigue strength (SFS) testing to determine the durability of adhesion of self-adhesive restorative materials compared to composite resin bonded with a universal adhesive.
A universal adhesive, Prime & Bond Active, was used in self-etch mode to bond Z-100 composite resin to enamel and dentin. Three commercially available restorative materials and one experimental material with self-adhesive properties, Activa (A), Fuji II LC(F), and Equia Forte (E) and ASAR-MP4 (S) were also bonded to enamel and dentin. The SBS and SFS were determined for all materials. A staircase method was used to determine the SFS with 10 Hz frequency for 50,000 cycles or until failure occurred.
On enamel, S generated similar values to the adhesive/composite materials and higher values than F, E, and A. On dentin, the composite/universal adhesive showed significantly higher SBS and SFS than the self-adhesive materials. S, F, and E generated higher values than A on dentin.
SBS and SFS values to enamel were similar for all materials tested except Activa which generated lower enamel values. On dentin surfaces, the self-adhesive materials generated similar SBS and SFS, with the exception of Activa. Those values were lower than that generated with composite resin and a universal adhesive.
使用剪切结合强度（SBS）和剪切疲劳强度（SFS）测试来确定自粘修复材料的粘结耐久性与通用粘结剂复合树脂的粘结耐久性的比较。
采用自酸蚀模式将通用粘结剂 Prime & Bond Active 用于将 Z-100 复合树脂粘结到牙釉质和牙本质上。还将三种市售的修复材料和一种具有自粘性能的实验材料 Activa（A）、Fuji II LC（F）、Equia Forte（E）和 ASAR-MP4（S）粘结到牙釉质和牙本质上。对所有材料均进行 SBS 和 SFS 测定。采用阶梯法在 10 Hz 频率下进行 SFS 测试，循环 50,000 次或直至发生故障。
在牙釉质上，S 产生与粘结剂/复合树脂相似的值，并且高于 F、E 和 A。在牙本质上，复合树脂/通用粘结剂显示出比自粘材料更高的 SBS 和 SFS。在牙本质上，S、F 和 E 产生的值高于 A。
除 Activa 产生较低的牙釉质值外，所有测试材料的牙釉质 SBS 和 SFS 值均相似。在牙本质表面，自粘材料产生相似的 SBS 和 SFS，但 Activa 除外。这些值低于复合树脂和通用粘结剂产生的值。
