| This study was conducted to compare the disinfectant effects of Nanosil D2 and Korsolex
extra on thermoset acrylic resin contaminated with Streptococcus mutans and Bacillus
subtilis. 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 S. mutans and the samples of another group were placed
in a suspension containing B. subtilis. 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 P < 0.05. At 1 h, Bacillus
level of Nanosil D2 was significantly lower than that of Korsolex extra, and at all ½, 1,
and 2 h, the level of Streptococcus in Nanosil D2 solution was significantly lower than
that of Korsolex extra (P < 0.05). Bacillus and Streptococcus levels showed significant
reduction in both solutions over time. The disinfecting power of Nanosil D2 is more
than that of Korsolex extra. |
