For reasons of hygiene, we recommend using a disposable
protective sleeve for each patient. Make sure to fit the pro-
tective sleeve closely to the light probe. Disinfect
contaminated surfaces of the device and anti-glare cones
(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, charging base and particu-
larly 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.
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 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.
Sterilization
Thorough cleaning and disinfecting is imperative to ensure
that the subsequent sterilization is effective. Use only auto-
clave 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.
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 regu-
larly 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.
