Killing Bacteria....
Aquatic biofilms,
which are well-organized communities of microorganisms, are widespread in
nature. They constitute a major problem in many environmental, industrial and
medical settings. The use of advanced techniques has revealed biofilm
structure, formation and ecology. Special attention was given to the build-up
of biofilm in dental unit waterlines (DUWLs), which are small-bore flexible
plastic tubing to bring water to different handpieces. They are coated with
well-established biofilms. Active biofilm is a source of microbial
contamination of DUWLs water. The safety of dental treatment requires a good
quality of the water used. The knowledge of nature, formation and the ways to
eliminate the biofilm is the first step towards reducing health risk, both for
patients and dental personnel.
Interest in and
concern about the biofilms that occur in dental waterlines have been increasing
in recent years. Dental unit waterlines harbor considerable amounts of bacteria
that are derived from the biofilm on the inner surface of these lines. This
continuous reservoir of bacteria carries the potential of causing infection to
patients and dental workers. The majority of dental procedures require the use
of water for cooling instruments, irrigation, and oral rinsing, so it is
extremely important that the water used in oral procedures is of a high
quality. The present study illustrates the conditions in waterline tubing that
favor development of biofilms, and discusses the level of risk that such
microbial growth poses for both dental professionals and their patients. The
different methods to circumvent this problem are reviewed, and the recent
recommendations that should be adopted in the dental clinic to provide the
patients with water of acceptable microbiological standards are discussed.
