Is there a need for the CDC recommendations of a 3-minute pre-flush before beginning the dental treatment day and a 30-second flush between patients?
The CDC, with the new recommendations of 2004, have dropped the 3-minute pre-flush of water at the beginning of the treatment day after significant studies have demonstrated an inability to achieve the requested goal of >500CFUs/ml. The request by the CDC and Waterclave of 30-second water flushing between patients after dental waterline usage will remain.
