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 solu-
tion 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 effec-
tive alternative.
Sterilization
Thorough cleaning and disinfecting is imperative to
ensure that the subsequent sterilization is effective. Use
only autoclave sterilization for this purpose. The steriliza-
tion 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 sterili-
zation 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.
Battery contacts
To ensure reliable conductivity at all times, keep the
battery contacts free from possible contamination (e.g.
composite residue). For this purpose, clean the affected
contacts regularly in the course of the usual wipe
disinfection (after each patient).
Disposal
The curing light must not be disposed of as
urban waste. Dispose unserviceable batteries
and polymerization lights according to the
corresponding legal requirements in your
country. Batteries must not be incinerated.
