Ivoclar Vivadent Bluephase G4 Instrucciones De Uso página 9

Eye protection
Direct or indirect exposure of the eyes must be
prevented. Prolonged exposure to the light is
unpleasant for the eyes and may result in injury. To
optimize user safety, the device has been equipped with
intelligent anti-glare protection. For this, the "polyvision"
function must be activated (see 4. Operation). With the
polyvision function activated, the Bluephase G4
automatically senses if the handpiece is outside of the
mouth and automatically switches off the light if it has
been activated inadvertently.
In addition, we also recommend using the anti-glare
protective equipment supplied. Individuals who are
sensitive to light, who take photosensitizing drugs, have
undergone eye surgery, or work with the apparatus
(or in its vicinity) for long periods of time, should not be
exposed and should wear protective orange goggles
that absorb light below a wavelength of 515 nm. The
same applies for patients.
Battery
Caution: Use only original spare parts for Bluephase G4,
particularly Ivoclar Vivadent batteries and charging
bases. Do not short circuit battery. Do not touch the
battery contacts. Do not store at temperatures above
40 °C / 104 °F (or 60 °C / 140 °F for a short period).
Always store batteries charged. The storage period must
not exceed 6 months. May explode if disposed of in fire.
Please note that lithium-ion batteries may react with
explosion, fire and smoke development if handled
improperly or mechanically damaged. Damaged
lithium-ion batteries must no longer be used.
The electrolytes and electrolyte fumes released during
explosion, fire and smoke development are toxic and
corrosive. Do not touch leaking batteries with bare
hands. In case of contact with the eyes or skin,
immediately wash with copious amounts of water.
Avoid inhalation of fumes. In case of indisposition, see a
physician immediately. Remove electrolyte residue from
surfaces by washing/wiping with a moist cloth. Wash
contaminated pieces of clothing immediately.
Heat development
As is the case with all high-performance lights,
the high light intensity results in a certain heat
development. Prolonged exposure of areas near the
pulp and soft tissues may result in irreversible damage.
Therefore, this high-performance curing light must only
be operated by trained professionals.
Generally, the stipulated curing times,
particularly in areas near the pulp (adhesives:
10 seconds), must be observed.
Uninterrupted curing times of more than
20 seconds on the same tooth surface, as well
as direct contact with the gingiva, oral
mucous membrane or skin have to be
prevented. Polymerize indirect restorations at
intermittent intervals of 20 seconds or use
external cooling with an air stream. The
instructions regarding curing programs and
curing times must be observed (see Selecting
the curing program and the curing time). In
addition, the light emission window must
remain positioned exactly on the material to
be cured during the entire duration of the
curing cycle (e.g. by holding it in place using
a finger).
After several curing cycles on the same
tooth, there is a risk that the pulp suffers
damage caused by the increased
temperature!
