Light probe
Before you clean and/or disinfect the light probe, it
should be pretreated. This applies to both manual and
machine cleaning and disinfection.
Pretreatment
– Remove substantial contamination immediately after
use and no later than 2 hours after use. For this pur-
pose, thoroughly rinse the light probe under running
water (for at least 10 seconds). You may also use a suit-
able aldehyde-free disinfecting solution to prevent
blood residue from becoming irremovable.
– To remove contamination manually, use a soft brush or
a soft cloth. Partially polymerized composite can be
removed with alcohol and a plastic spatula, if neces-
sary. Do not use sharp or pointed instruments. They
may scratch the surface.
Cleaning and disinfection
For cleaning, immerse the light probe in a cleaning
solution in such a way that it is sufficiently covered with
liquid (ultrasound or careful brushing with a soft brush
can 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);
– bases (the maximum admissible pH value is 8.5);
– oxidizing agents (e.g. hydrogen peroxides).
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.
Sterilization
Thorough cleaning and disinfecting is imperative to
ensure that the subsequent sterilization is effective. Use
only autoclave sterilization for this purpose. Sterilization
time (exposure time at sterilization temperature) is at
least 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 the
light probe 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 device must not be disposed of in normal
domestic waste. Dispose unserviceable bat-
teries and polymerization lights according to
the corresponding legal requirements in your
country. Batteries must not be incinerated!
