These results show that the area becoming
contaminated during dental procedures is far
larger than previously thought and practically
encompasses the whole room. Only items necessary
for ongoing treatment should be out on work
surfaces, and other items should be stored in
closed cupboards. Disinfection between patients
should be made as easy as possible and should
extend to all contaminated areas. In general,
dental surgeries should be seen more as operating
theatres than offices in order to minimize the
risks of cross-infection. Protection of the face
and hair and personal hygiene of the personnel
after work should also be emphasized to control
colonization and spread of hospital bacteria in
the community.
