Bacterial invasion of dental unit water lines is a global issue, which if left untreated, leads to formation bacterial biofilm within the lines. The aim this study was determine number colony forming units (CFU) in waterlines Rehman college dentistry. Samples from air-water syringes 44 different various departments hospital were collected. Tip each syringe heated using direct flaming eliminate ...

BACKGROUND A frequent problem in dental units is the microbial contamination of water and biofilm formation in the water supply lines. After random identification of a bacterial contaminated dental unit (310 cfu/ml) in a practise with 3 dental units we implemented the present study to evaluate the efficacy of the PotoClean(®) technology, based on anodic oxidation. METHOD The efficacy of a reg...

BACKGROUND The maximum recommended level of microbial contamination of water from dental unit waterlines (DUWL) is 200 colony-forming units per milliliter (CFU/mL). This article addresses the importance of water selection in achieving that standard. METHODS Microbial contamination in water samples from 75 new dental units, with a closed-circuit water system, were compared using combinations o...

BACKGROUND Water supplied to the dental units must be of sufficient quality. The article presents the results of the microbiological analysis of cold municipal water which flows into a patient's disposable mouthwash cup, and demineralized water which flows through a waterline into the tool panel of a dental unit from the tank placed in the water group. MATERIAL AND METHODS In order to assess ...

The aim of the study was to assess microbial quality of water in dental unit waterlines in a dental school at Mangalore. Methodology: Water samples were taken from tap water for control, air/water syringe and the high speed hand piece of 20 dental units. The samples were transferred to the laboratory and streaked on the culture media namely Mac Conkey agar, Sabourauds dextrose media, Buffered c...

BACKGROUND Dental unit waterline system is considered potential source for contamination with Legionella species. The aim of this study was to determine if contamination of a dental unit water line system by Legionella pneumophila serogroup1 in the Mashhad School of Dentistry occurred in 2009. METHODS A total of 52 dental units were selected from all clinical departments of the Mashhad School...
