Infection control in healthcare sector especially dentistry is an area of major concern. The water used for irrigation and cooling of devices has the potential to get contaminated due to the passage of water through thin long pipelines commonly referred as dental unit water lines (DUWL). It has been proven that contaminated water of DUWL can lead to formation of a biofilm which can host pathogenic micro-organisms and has the potential to infect patients and health professionals. This paper reviews the factors responsible for contamination of DUWL, biofilm composition and provides a detailed update regarding maintenance of DUWL by various means thereby leading to infection control in dental clinics.
