Pretreatment; Cleaning And Disinfection - Ivoclar Vivadent Bluephase style Mode D'emploi

Light probe
Before cleaning and/or disinfecting the light probe, it
should be pretreated. This applies to both machine and
manual cleaning and disinfection.

Pretreatment

– Remove gross contamination immediately after use or
within 2 hours. For that 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 with the help of a plastic spatula.
Do not use sharp or pointed objects. They may scratch
the surface.

Cleaning and disinfection

For cleaning, immerse the light probe in a cleaning
s olution 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)
– alkaline solutions (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 with fresh water (for at least 10 seconds).
Cleaning in a thermal disinfector is an effective alternative.
Sterilization
Intensive cleaning and disinfecting is imperative to
ensure the subsequent sterilization is effective. Use only
autoclave sterilization for this purpose.
The sterilization temperature must not exceed 134 °C
(273 °F). Sterilization time (exposure time at sterilization
temperature) is at least 15 minutes at 121 °C (250 °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.
Afterwards, check the light probe for damage. Hold it
against the light. If certain segments appear black, glass
fibres are broken. In such a case, replace the light probe
with a new one.
Disposal
The curing light must not be disposed of
in the normal domestic waste. Dispose
unserviceable batteries and polymerization
lights according to the corresponding legal
requirements in your country. Batteries must
not be incinerated.
