To evaluate the effect of moist bonding on shear bond strength of resin-based composite to enamel using different adhesive systems.
Six restorative systems were selected for this study: OptiBond FL/Prodigy, Solid Bond/Charisma F, Syntac Single Component/Tetric, Prime&Bond 2.1/Spectrum TPH, Single Bond/Z100, Etch&Prime 3.0/Degufill Mineral. Flat enamel surfaces were ground on the buccal and lingual aspects of 80 extracted human molars. OptiBond FL and Solid Bond were tested with and without primer application. Prior to application of the adhesives, the enamel was either carefully dried with compressed air (dry bonding) or blot dried with a cotton pellet (moist bonding). Shear bond strength was determined with a universal testing machine after 24-hour storage in 0.9% NaCl at 37 degrees C.
Moist bonding did not significantly affect shear bond strength to enamel of the adhesives tested except for Solid Bond without primer application. Primer contamination of the etched enamel did not significantly influence bond strength, neither in the dry bonding nor in the moist bonding group. Of all adhesives tested in both groups, the highest mean bond strength was observed with Prime&Bond 2.1 and the lowest with Etch&Prime 3.0.
使用不同的粘结系统评估湿粘结对树脂基复合材料与牙釉质剪切粘结强度的影响。
本研究选择了六种修复系统：OptiBond FL/Prodigy、Solid Bond/Charisma F、Syntac单组分/Tetric、Prime&Bond 2.1/Spectrum TPH、Single Bond/Z100、Etch&Prime 3.0/Degufill Mineral。在80颗拔除的人磨牙的颊面和舌面磨出平坦的牙釉质表面。OptiBond FL和Solid Bond分别在使用和不使用底漆的情况下进行测试。在施加粘结剂之前，牙釉质要么用压缩空气小心吹干（干粘结），要么用棉球吸干（湿粘结）。在37℃的0.9%氯化钠溶液中储存24小时后，用万能试验机测定剪切粘结强度。
除未使用底漆的Solid Bond外，湿粘结对所测试粘结剂与牙釉质的剪切粘结强度没有显著影响。蚀刻牙釉质的底漆污染在干粘结组和湿粘结组中均未对粘结强度产生显著影响。在两组测试的所有粘结剂中，Prime&Bond 2.1的平均粘结强度最高，Etch&Prime 3.0的平均粘结强度最低。
