5. Maintenance and Cleaning
For reasons of hygiene, we recommend using a
disposable protective sleeve for each patient. Make sure
to fit the protective sleeve closely to the light probe.
Disinfect contaminated surfaces of the device and anti-
glare cones (FD 366/Dürr Dental, Incidin Liquid/Ecolab)
Sterilize the light probe before each use if disposable
protective sleeves are not used. Make sure that no
liquids or other foreign substances enter the handpiece,
charging base and particularly the power pack during
cleaning (risk of electrical shock). Disconnect the
charging base from the power source when cleaning it.
Housing
Wipe the handpiece and handpiece holder with a
customary aldehyde-free disinfecting solution. Do not
clean with highly aggressive disinfecting solutions
(e.g. solutions based on orange oil or with an ethanol
content of more than 40%), solvents (e.g. acetone), or
pointed instruments, which may damage or scratch the
plastic. Clean dirty plastic parts with a soapy solution.
Light probe
Before cleaning and/or disinfecting the light probe,
pretreat it. This applies to both automated and manual
cleaning and disinfection:
– Remove substantial contamination immediately after
use or 2 hours after that at the latest. For this purpose,
thoroughly rinse the light probe under running water
(for at least 10 seconds). Alternatively, use a suitable
aldehyde-free disinfecting solution to prevent the
fixation of blood.
– To remove contamination manually, use a soft brush
or soft cloth. Partially polymerized composite can be
removed with alcohol and a plastic spatula, if
necessary. Do not use sharp or pointed objects, as
they may scratch the surface.
Cleaning and disinfection
For cleaning, immerse the light probe in a cleaning
solution and ensure that it is sufficiently covered with
liquid (ultrasound or careful brushing with a soft brush
may support the effect). A neutral-enzymatic cleaning
agent is recommended.
When cleaning and disinfecting, please make sure that
the agents used are free of:
– organic, mineral and oxidizing acids (the minimum
admissible pH value is 5.5)
– alkaline solution (the maximum admissible pH value
is 8.5)
– oxidizing agent (e.g. hydrogen peroxide)
Afterwards, remove the light probe from the solution
and thoroughly rinse it under running water (for at least
10 seconds). Cleaning in a thermal disinfector is an
effective alternative.
