To determine the effect of All-Bond 2 adhesive on the shear bond strengths to dentin of Fuji II LC, Photac-Fil, and Vitremer.
The occlusal surfaces of 60 extracted human third molars were ground flat to expose dentin and were polished to 600 grit. The teeth were randomly assigned to six groups (n = 10). In three groups, dentin was treated using the conditioner or primer recommended by the manufacturer. In the remaining groups, dentin was treated with All-Bond 2 etchant, primer, and adhesive. Restorative materials were applied to the treated surfaces in gelatin capsule matrices and were light-cured. Specimens were thermocycled, and shear bond strengths were determined using a materials testing machine.
The use of All-Bond 2 improved the mean bond strength of Photac-Fil from 1.7 to 8.7 MPa, but decreased the bond strength of Vitremer from 7.3 to 5.5 MPa. The bond strengths of Fuji II LC were 7.5 and 7.9 MPa, with and without the use of All-Bond 2, respectively. ANOVA and Duncan's multiple range test showed that only the difference for Photac-Fil was statistically significant.
确定全粘结2号粘结剂对富士II LC、光固化玻璃离子水门汀和维他美修复材料与牙本质之间剪切粘结强度的影响。
将60颗拔除的人第三磨牙的咬合面磨平以暴露牙本质，并抛光至600目。将牙齿随机分为六组（每组n = 10）。三组中，按照制造商推荐使用调节剂或底漆处理牙本质。其余组中，牙本质用全粘结2号蚀刻剂、底漆和粘结剂处理。在明胶胶囊基质中将修复材料应用于处理过的表面并进行光固化。对样本进行热循环处理，并用材料试验机测定剪切粘结强度。
使用全粘结2号使光固化玻璃离子水门汀的平均粘结强度从1.7 MPa提高到8.7 MPa，但使维他美的粘结强度从7.3 MPa降低到5.5 MPa。使用和未使用全粘结2号时，富士II LC的粘结强度分别为7.5 MPa和7.9 MPa。方差分析和邓肯多重极差检验表明，只有光固化玻璃离子水门汀的差异具有统计学意义。
