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...

OBJECTIVES Aerosols generated during dental procedures have been reported to contain endotoxin as a result of bacterial contamination of dental unit water lines. This study investigated the determinants of airborne endotoxin exposure in dental healthcare settings. METHODS The study population included dental personnel (n = 454) from five academic dental institutions in South Africa. Personal ...

Dental health care providers and patients are exposed during ongoing work to contamination by the water used in the dental units, due to accidental swallowing or aspiration of the sprays generated by the high-speed handpiece and the threeway syringe. This study evaluated the quality of water in dental units in the public dental care system of Maceio, Alagoas, Brazil, by conducting analyses of c...

background: it is known that dental unit waterline can be a source of infection. the aim of this study was to evaluate the effi cacy of a mouthwash, chlorhexidine, in controlling microbial and fungal contamination of dental unit waterlines. materials and methods: in the present experimental study, the water in high-speed handpieces and air/water syringes of 35 dental units in a dental school wa...

A water quality study of dental units showed biofilm and opportunistic microorganisms. We report the steps that ultimately allowed us to obtain water quality as water for standard care with no pathogens throughout all dental units. In summary, treatment with continuous disinfection associated with use of sterile water allowed us to restore the water quality at the output of dental care units wh...

Water lines are an importan! source of potentíal contamination. Every dental unit is equipped with small-bore flexible plastic tubing to bring water to different hand pieces, such as the air/water syringe, the ultrasonic scaler or the high-speed hand piece. Most dental units are connected directly to municipal distribution systems for potable water and chlorinated or not, this water contains di...

BACKGROUND This study addresses the efficacy of an automated decontamination protocol using the germicide 'tetra acetyl ethylene diamine (TAED) perborate' (Farmec SpA, Italy). The germicide TAED perborate protocol is used in the Castellini Dental Units fitted with an Autosteril unit (an automated device that can cycle 0.26% TAED perborate solution and sterile water for cleaning the water system...

Objective: A cross-sectional study was carried out to assess standard precaution practices among dental personnel and to investigate microbial counts in indoor air samples collected from a hospital dental clinic before and during dental works. Material and Method: Thirty dental personnel who voluntarily participated were interviewed using a questionnaire towards demographic information and stan...

background : dental unit waterlines (duwls) are ideal nvironment for development of microbial biofilms. microbial contamination of water in duwls is thought to be the result of biofilm formation as it could serves as a haven for pathogens. the aim of this study was to assess microbial quality of water in dental unit waterlines of dental units located at the dental school of isfahan university o...
