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 con-
taminated surfaces of the device and anti-glare cones (e.g.
FD 366/Dürr Dental, Incidin Liquid/Ecolab) and 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, the handpiece holder and
particularly the power pack during cleaning (risk of electrical
shock). Disconnect the handpiece 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 soiled plastic parts
with a soap solution.
Light probe
Before cleaning and/or disinfecting the light probe, it
should be pretreated. This applies to both automated and
manual cleaning and disinfection.
Pretreatment
– Remove gross contamination immediately after use or
within 2 hours. 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 (ultra-
sound or careful brushing with a soft brush may support
the effect). A neutral-enzymatic cleaning agent is recom-
mended. When cleaning and disinfecting, please make sure
that the agents used are free of
– organic, mineral and oxidizing acids (the minimum admis-
sible pH value is 5.5)
– alkaline solutions (the maximum admissible pH value is
8.5)
– oxidizing agents (e.g. hydrogen peroxide)
Afterwards, remove the light probe from the solution and
thoroughly rinse it under running fresh water (for at least
10 seconds). Cleaning in a thermal disinfector is an effect-
ive alternative.
Sterilization
Thorough cleaning and disinfecting is imperative to ensure
that the subsequent sterilization is effective. Use only
autoclave sterilization for this purpose. The sterilization
time (exposure time at sterilization temperature) is
4 minutes at 134 °C (273 °F); pressure should be 2 bar
(29 psi). Dry the sterilized light probe using either the
special drying program of your steam autoclave or hot air.
The light probe has been tested for up to 200 sterilization
cycles.
After that, check the light probe for damage. Hold it
against light. If individual segments appear black, glass
fibres are broken. If this is the case, replace the light probe
with a new one.
Disposal
The curing light must not be disposed of as
urban waste. Dispose unserviceable polymeriza-
tion lights according to the corresponding legal
requirements in your country.
