Molecular analysis for bacterial contamination in dental unit water lines.
Bacterial contamination in dental unit waterlines (DUWLs) was evaluated by molecular techniques in addition to the conventional culture method. Water samples (n=8) from DUWLs were investigated for heterotrophic bacteria by culture method using R2A agar. The selected bacterial antibiotic-resistance genes and Legionella species-specific 16SrDNA were identified by PCR. The profiles of bacterial co...
متن کاملEvaluation of Bacterial Contamination in Dental Unit Water Lines in Zahedan in 2016-2017
Background & Aim: Due to a constant contact of dentists and patients with water and aerosols generated from the dental units, the quality of dental unit waters is very important. This study aimed to evaluate bacterial contamination of dental unit water lines in Zahedan in 2016-2017. Methods: In this descriptive analytical study, 2304 water samples from four parts of unit including cup filler, ...
متن کاملBacterial contamination of dental unit waterlines
Safety of patients and dental personnel requires the appropriate microbiological water quality in dental units. During treatment, patients and dental workers are exposed both to direct contact with bacteria-contaminated water in the form of splatter and with contaminated water aerosol emitted during work by unit handpieces, including rotating and ultrasonic instruments. The aim of the study was...
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 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 ...
