The service of healthcare providers is regulated by a multitude of laws and regulations
regarding infection control. It is, however, not evident whether the control is sufficient or not to avoid
cross-contamination at dental clinics. Two different chemical disinfections have been used at the
clinics. Simultaneously a hand hygiene campaign has been running to avoid contaminating the
computers and common areas. We do not know which chemical disinfectant is best suited for our
purposes or whether the campaign has an effect or not. The aim of the study was to examine the
level of surface disinfection at the clinic and to assess whether there were differences between the
two chemical disinfectant solutions by ATP measurements and Clean Trace Luminometer (3M Espe).
The results show that it was possible, but difficult, to achieve an acceptable level of infection control
by the routines used at the time of the study. Some points were contaminated in most units. There
were larger differences among the individual operators than the chemical solutions they used or their
student status. In general the level of surface cleanliness was lower than recommended, but the
ongoing campaign seems to have had an effect. The routines at the clinics must be followed more
strictly and controls should be performed in order to achieve acceptable infection control.
