Simulated clinical conditions were used to test the effect of sterilization on rubber-dam clamp stiffness and dimension. Sixty Hygienic and Ivory W7 clamps were either steam or dry heat sterilized and compared to controls. Stiffness and dimensional change between Ivory clamp groups was significant (p<.0001); the sterilized clamps showed less change than the controls. Hygienic groups showed a significant different between the control and dry heat groups (p<.05); the sterilized clamps showed less change than the controls. The change in stiffness and interjaw width for all Ivory clamps compared to all Hygienic clamps was significant (p<.0001). The Hygienic clamps changes less than the Ivory clamps. The results indicate that steam and dry heat sterilization do not affect retention of rubber-dam clamps.
采用模拟临床条件来测试灭菌对橡皮障夹的硬度和尺寸的影响。六十个卫生型和象牙色W7夹分别进行蒸汽灭菌或干热灭菌，并与对照组进行比较。象牙色夹组之间的硬度和尺寸变化显著（p<0.0001）；灭菌后的夹子比对照组变化更小。卫生型夹组的对照组和干热组之间存在显著差异（p<0.05）；灭菌后的夹子比对照组变化更小。与所有卫生型夹相比，所有象牙色夹的硬度和夹间宽度变化显著（p<0.0001）。卫生型夹的变化小于象牙色夹。结果表明，蒸汽灭菌和干热灭菌不会影响橡皮障夹的固位。
