Effects of Hydrogen Peroxide on Dental Unit Biofilms and Treatment Water Contamination
OBJECTIVES To study effects of various concentrations of hydrogen peroxide on mature waterline biofilms and in controlling planktonic (free-floating) organisms in simulated dental treatment water systems; and to study in vitro the effects of 2%, 3%, and 7% hydrogen peroxide on the removal of mature biofilms and inorganic compounds in dental waterlines. METHODS Four units of an automated denta...
متن کاملImpact of cleaning regimes on dental water unit contamination.
Microorganisms that have been identified in dental unit waterlines (DUWLs) are of concern because they can cause infections, especially in immunocompromised patients. This study aimed to assess the incidence of microbial contamination in DUWLs before and after intervention to reduce contamination, and to investigate the presence of coliforms, Escherichia coli and Pseudomonas aeruginosa. Water s...
متن کاملMicrobial diversity of biofilms in dental unit water systems.
We investigated the microbial diversity of biofilms found in dental unit water systems (DUWS) by three methods. The first was microscopic examination by scanning electron microscopy (SEM), acridine orange staining, and fluorescent in situ hybridization (FISH). Most bacteria present in the biofilm were viable. FISH detected the beta and gamma, but not the alpha, subclasses of Proteobacteria: In ...
متن کاملMultiple approaches to control dental unit water line biofilm contamination
Biofilms form rapidly on dental unit waterlines. The specific design of dental units favors bacteria to colonize surfaces and to form biofilm in water supply tubes, including dental unit water line (DUWL). The majority of the organisms in the biofilm are harmless environmental species, but some dental units may harbour opportunistic respiratory pathogens. Microbiological control of dental unit ...
