Eye protection
Direct or indirect exposure of the eyes must be prevented.
Prolonged exposure to the light is unpleasant to the eyes
and may result in injury. Therefore, using the supplied anti-
glare cones is recommended. Individuals who are generally
sensitive to light, who take photosensitizing drugs, have
undergone eye surgery, or people who work with the
apparatus or in its vicinity for long periods of time should
not be exposed to the light of this device Therefore, they
should wear protective goggles (orange) that absorb light
below 515 nm.
Heat development (burn hazard)
As it is the case with all high-performance lights, the high
light intensity results in a certain heat development. Pro-
longed exposure of areas near the pulp and soft tissues
may result in irreversible or reversible damage. Therefore,
the recommended curing times have to be observed.
Uninterrupted curing times of more than 40 seconds on the
same tooth surface, as well as direct contact with the gin-
giva, oral mucous membrane or skin have to be prevented.
Polymerize indirect restorations at intermittent intervals of
20 seconds each or use external cooling with an air stream.
