Legionella in Dental Practices
All dental surgeries are required to undertake legionella risk assessments of their Dental Unit Water Lines (DUWL) and hot and cold water systems. Whilst the reported incidents of legionella are low, there has recently been growing cause for concern, with legionella being found in up to 25% of DUWLs in the south-west.
Legionella can be transmitted via contaminated water droplets, aerosols, and via contaminated instruments such as ultrasonic scalers or high-speed handpieces.
Assessments are necessary periodically, and water samples should be taken to further aid the analysis of the water quality. Records must be kept of routine checks, cleaning and disinfection as part of a legionella management programme.
The possibility of legionella can be reduced through a number of measures including ensuring on frequent water turnover to help avoid a build-up of sludge in the pipes and water tank. Cold water must be stored at temperatures less than 20°C, and hot water at a minimum of 60°C and 55°C in healthcare premises at the outlet (taps). DUWLs and infrequently used taps need to be flushed on a week basis.
If your water is cloudy, tastes different or has an odour, call us to arrange a microbiological investigation as these conditions may promote the growth of legionella.
