This study was conducted to compare the disinfectant effects of Nanosil D2 and Korsolex extra on thermoset acrylic resin contaminated with and . In this experimental study, 90 acrylic samples were made and sterilized. Two samples were cultured as a sterilization control in brain-heart infusion (BHI) and the rest of samples were divided into two groups. Samples of one group were placed in a bacterial suspension of and the samples of another group were placed in a suspension containing . Each group was divided into two subgroups for immersion in Nanosil or Korsolex extra solutions. Seven samples were selected from each group at each of 30 min, 1 h, and 2 h and transferred to the BHI test tube, and their turbidity was evaluated after 24 h. SPSS 17 software was used to analyze the data, and the significance level of test was considered < 0.05. At 1 h, level of Nanosil D2 was significantly lower than that of Korsolex extra, and at all ½, 1, and 2 h, the level of in Nanosil D2 solution was significantly lower than that of Korsolex extra ( < 0.05). and levels showed significant reduction in both solutions over time. The disinfecting power of Nanosil D2 is more than that of Korsolex extra.
本研究旨在比较纳米硅D2和超强科索莱克斯对被[具体细菌名称1]和[具体细菌名称2]污染的热固性丙烯酸树脂的消毒效果。在这项实验研究中，制作并灭菌了90个丙烯酸样品。将两个样品作为灭菌对照在脑心浸液（BHI）中培养，其余样品分为两组。一组样品置于[具体细菌名称1]的细菌悬液中，另一组样品置于含有[具体细菌名称2]的悬液中。每组再分为两个亚组，分别浸入纳米硅或超强科索莱克斯溶液中。在30分钟、1小时和2小时时，从每组中各选取7个样品转移至BHI试管中，并在24小时后评估其浊度。使用SPSS 17软件分析数据，检验的显著性水平设定为<0.05。在1小时时，纳米硅D2的[细菌名称1]水平显著低于超强科索莱克斯，并且在所有0.5小时、1小时和2小时时，纳米硅D2溶液中的[细菌名称2]水平均显著低于超强科索莱克斯（<0.05）。随着时间的推移，两种溶液中的[细菌名称1]和[细菌名称2]水平均显著降低。纳米硅D2的消毒能力强于超强科索莱克斯。
