The purpose of this study was to investigate the effect of dentinal disinfection with a 2% chlorhexidine or a 0.11% I2-KI/CuSO4 solution on the shear bond strength of three resin-modified glass-ionomer cements: Fuji II LC, Photac-Fil, and Vitremer. The occlusal surfaces of extracted human teeth were flattened to dentin. Specimens were randomly assigned to one of nine treatment groups (n = 12). For each glass-ionomer material, there was a control group and two treatment groups in which the dentin was treated with either a 2% chlorhexidine or a 0.11% I2-KI/CuSO4 solution before the dentin was treated with the recommended dentin conditioner prior to glass-ionomer bonding. Specimens were stored for 1 day in water, thermocycled, and tested in shear until failure. The chlorhexidine solution did not significantly affect the shear bond strengths of any of the cements, but the I2-KI/CuSO4 solution significantly lowered the bond strengths of Vitremer and Fuji II LC compared to the controls.
本研究的目的是调查用2%氯己定或0.11%碘 - 碘化钾/硫酸铜溶液进行牙本质消毒对三种树脂改性玻璃离子水门汀（富士II LC、Photac - Fil和Vitremer）剪切粘结强度的影响。将拔除的人牙的咬合面磨平至牙本质。标本被随机分配到九个治疗组之一（n = 12）。对于每种玻璃离子材料，有一个对照组和两个治疗组，在使用推荐的牙本质调节剂处理牙本质以进行玻璃离子粘结之前，先用2%氯己定或0.11%碘 - 碘化钾/硫酸铜溶液处理牙本质。标本在水中储存1天，进行热循环处理，并进行剪切测试直至破坏。氯己定溶液对任何一种水门汀的剪切粘结强度均无显著影响，但与对照组相比，碘 - 碘化钾/硫酸铜溶液显著降低了Vitremer和富士II LC的粘结强度。
