| FAQ - Dental Unit Waterlines - 2015
In regards to water lines… we remove our water bottles at the end of each day and let them air dry. My question to you is what is OSAP’s recommendation with what should be done with the water tubing that hangs down? We were wondering since there is probably dirt stirred up into the air and the possibility of a dirty mop hitting the tubing when the floors are cleaned by the cleaning crew. We had discussed placing another bottle over it but we were unsure if this should also air dry??
Ask OSAP does not review, evaluate, certify, recommend or endorse products. Ask OSAP also does not provide technical support for specific products. If you have further questions about procedures and specific products it is recommended that you consult with the manufacturer’s written instruction manual and/or contact directly the manufacturer of your product to obtain the product instructions for use (IFU). Ask OSAP is not the position to know the specifics of all products and the manufacturer can best provide you with an answer to this question.
In general, the 2003 CDC guidelines for infection control in dentistry states as follows:
Maintenance and Monitoring of Dental Unit Water
DHCP should be trained regarding water quality, biofilm formation, water treatment methods, and appropriate maintenance protocols for water delivery systems. Water treatment and monitoring products require strict adherence to maintenance protocols, and noncompliance with treatment regimens has been associated with persistence of microbial contamination in treated systems (345). Clinical monitoring of water quality can ensure that procedures are correctly performed and that devices are working in accordance with the manufacturer’s previously validated protocol.
Dentists should consult with the manufacturer of their dental unit or water delivery system to determine the best method for maintaining acceptable water quality (i.e., <500 CFU/mL) and the recommended frequency of monitoring. Monitoring of dental water quality can be performed by using commercial selfcontained test kits or commercial water-testing laboratories. Because methods used to treat dental water systems target the entire biofilm, no rationale exists for routine testing for such specific organisms as Legionella or Pseudomonas, except when investigating a suspected waterborne disease outbreak (244). 1
