Maintenance And Cleaning - Ivoclar Vivadent Bluephase G4 Mode D'emploi

5. Maintenance and Cleaning

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 guide.
Disinfect contaminated surfaces of the device and anti-
glare cones (FD 366/Dürr Dental, Incidin Liquid/Ecolab)
Sterilize the light guide 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 particularly the power pack during
cleaning (risk of electrical shock). Disconnect the
charging base from the power source when cleaning it.
Cleaning the 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.

Pre-treating the light guide
Before cleaning and/or disinfecting the light guide,
pretreat it. This applies to both automated and manual
cleaning and disinfection:
– Remove substantial contamination immediately after
use or 2 hours after that at the latest. For this purpose,
thoroughly rinse the light guide under running water
(for at least 10 seconds). Alternatively, use a suitable
aldehyde-free disinfecting solution to prevent the
adherence 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.
Manually cleaning and disinfecting the light guide
For manual cleaning, immerse the light guide in
cleaning solution. Make sure that the light guide is
entirely submerged in the solution and allow it to soak
for the recommended time (ultrasonic cleaning or
careful brushing with a soft brush may enhance the
effectiveness of the procedure). We recommend using a
neutral enzymatic detergent.
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 guide from the solution
and thoroughly rinse it under running, germ-free water
(for at least 10 seconds).
For disinfecting the light guide, immerse it in
disinfectant solution; make sure that the light guide is
entirely submerged in the solution. We recommend
using a o-phthalaldehyde-containing disinfectant.
After the light guide has been disinfected, remove it
from the solution and rinse it again thoroughly under
running germ-free water (for at least 10 seconds). Then
dry the light guide with a clean towel.
Please observe the instructions given by the
manufacturer of the detergent and disinfectant.
