OBJECTIVE The purpose of the study was to examine the substantivity of a new disinfectant against biofilm formation in the dental unit waterlines. MATERIALS AND METHODS Twenty dental units were selected for the study and divided into two groups: Group A (dental unit waterlines treated with the disinfectant) and Group B (untreated dental unit waterlines). Biofilm formation was monitored in bot...

Interest in and concern about the biofilms that occur in dental equipment and waterlines have been increasing in recent years. Dental unit waterlines are ideal environments for the growth of microorganisms entering dental units from the municipal water supply. This article describes the conditions in waterline tubing that favour development of biofilms and discusses the level of risk that such ...

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...

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...

BACKGROUND In response to concerns of bacterial biofilm colonization of dental unit waterlines, a wide range of commercial intermittent and continuous chemical treatments for dental unit waterlines have been developed and marketed. There has been little research on the possible effect of continuous chemical treatment regimens on dentin-bonding agents. The authors evaluate the effect of four pro...

Context. Dental unit waterlines may be heavily contaminated with microorganisms and are a potential source of infection for both practicing staff and immunocompromised patients particularly. Contamination of dental unit water lines could be inhibited with the use of disinfectants. The present study investigates the effect of aloe-vera-based disinfectant in reducing the microbial growth in denta...
