In vitro and in field evaluation of the efficacy of disinfectants
In
this study we evaluated (1) the efficacy of a protocol that combines
hydrogen peroxide (shock treatment) and ICX® tablets (continuous
treatment) for the control of microbial contamination in dental
unit water lines, and (2) the in vitro antimicrobial activity of
ICX® tablets on collection and wild strains isolated from dental
chair output waters. To assess the treatment effectiveness, the
microbial load in the output water samples of three dental chairs
were investigated: one control chair received only shock treatment.
In vitro bactericidal activity was tested against Staphylococcus
aureus and Pseudomonas aeruginosa. Data obtained from samples collected
from chairs treated with ICX® and shock treatment and data from
the control chair did not differ significantly on the basis of microbial
load. In the in vitro study, the product was unable to kill Gram-negative
bacteria. These results show that the continuous introduction of
ICX® was not effective in maintaining low counts of the heterotrophic
bacteria in the output water of dental devices, and shock treatment
may be needed more frequently than monthly
