%X several studies have reported a new way for infection in dentistry referred to dental unit waterlines. it has been described that water£¿s hydrodynamics promotes the biofilm formation in those devices. among other bacteria, pseudomonas aeruginosa is one of the most common pathogens isolated from dental unit waterlines (75-100%) which can cause infection to humans with immune deficiencies. the dental units, at the service of integral adult attention, faculty of dentistry, university of los andes, m¨¦rida-venezuela, can have either external potable tap water supply or container devices. in both cases, the attachment of pseudomonas species to biofilm could be considered for the inner surfaces of the waterlines. the aim of this study was to isolate pseudomonas species from the dental unit waterlines and from the incoming potable tap water supply. through a descriptive, non experimental, quantitative, cross-sectional study, 25 samples of water leaving from dental units and incoming from potable water supply were evaluated using microbiological analysis. the presence of p. aeruginosa and p. fluorescens, among other pathogens to human, was demonstrated in the water from 3-in-1 syringe, turbine and external water supply. these results indicate a high risk of cross-infection due to deficiencies in sanitary requirements for potable water used in dental procedures
