Biofilm, Dental Unit Water Line and Its Control
Biofilms are well-organized communities of cooperating microorganisms that can include bacteria, algae, fungi and diatoms. Dental unit waterlines (DUWL) are an integral part of dental surgery equipment, supplying water as a coolant, primarily for air turbine and ultrasonic scalers. Surveys of dental unit waterlines (DUWLs) indicate that biofilm formation is a universal problem and great majorit...
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 ...
متن کاملMicrobial biofilm formation and contamination of dental-unit water systems in general dental practice.
Dental-unit water systems (DUWS) harbor bacterial biofilms, which may serve as a haven for pathogens. The aim of this study was to investigate the microbial load of water from DUWS in general dental practices and the biofouling of DUWS tubing. Water and tube samples were taken from 55 dental surgeries in southwestern England. Contamination was determined by viable counts on environmentally sele...
متن کاملFrequency evaluation of Pseudomonas SPP contamination in the dental unit water line system at Mashhad dental school
Background and aim: One of the well-known bacteria in dental unit water contamination is Pseudomonas aueroginosa. The aim of the present study was to evaluate the amount of Pseudomonas aeruginosa species infection in the dental unit water samples of Dental Faculty of Mashhad University of Medical Sciences. Material and methods: Water samples collected randomly from the turbines of 10% of the ac...
متن کاملA new chemical formulation for control of dental unit water line contamination: An 'in vitro' and clinical 'study'
BACKGROUND: Water delivered by dental units during routine dental practice is highly contaminated. The aim of this study is to evaluate the efficacy of a new chemical solution flushed through Dental Unit Water Lines (DUWL) for the control of contamination inside dental units. MATERIALS AND METHODS: Six old dental units equipped with a device designed to automatically flush disinfecting solution...
