DENTSPLY SmartLite iQ Guía De Operaciónes página 3

INTRODUCTION
The SmartLite ® iQ ™ 2 unit utilizes light emitting diode (LED) technol-
ogy for the polymerization of light cured materials in the 450 to
475 nm visible light range.
INDICATIONS
The SmartLite iQ2 unit is designed for curing camphorquinone-
based visible light cured (VLC) materials.
CONTRAINDICATIONS
The SmartLite iQ2 Curing Light is contraindicated for use with
persons who have a medical history indicating photobiologic
reactions (including persons with solar urticaria or erythropoietic
protoporphyria) or who are using photosensitizing drugs.
WARNINGS
1. The SmartLite iQ2 Curing Light emits high intensity visible light
radiation. Prolonged continuous exposure to eyes, oral mucosa
or exposed skin can result in injury or irritation. When curing,
position the light probe tip directly over the polymerizable mate-
rial and avoid extraneous exposure to soft tissue for prolonged
periods. Wear suitable protective clothing and eye protection
designed to filter blue-violet and ultraviolet radiation. Securely
attach protective light shield before use.
Eye exposure: Avoid prolonged exposure to unprotected eyes.
Prolonged exposure may cause blurring or starring of vision, or
result in visual after-image. In most cases these phenomena are
temporary and do not require treatment. If vision abnormalities
persist, consult a physician.
Skin Contact: Avoid prolonged exposure to skin. If skin rash,
sensitization or other reaction occurs, discontinue use and seek
medical attention.
Oral mucosa contact: Avoid prolonged exposure to oral soft
tissues. Prolonged exposure may cause soft tissue irritation or
burns. Most minor reactions require only thorough cleansing and
palliative treatment. If irritation persists, seek medical attention.
2. The SmartLite iQ2 Curing Light is an electric device. To avoid
electric shock:
• Do not attempt to change the Curing LED, open, or alter the
unit in any way (other than as directed in these Directions for
Use).
• Do not introduce any foreign objects into the housing of the
unit
• Connect the power plug into a suitably grounded and
approved outlet. If using an extension cable, make sure that
the ground line is not interrupted.
• Always unplug the base/charger before disinfecting.
3. The SmartLite iQ2 unit is not suitable for use in the presence of
a flammable anesthetic mixture with air or nitrous oxide. Use in
well ventilated area.
SAFETY PRECAUTIONS
1. This product is intended to be used only as specifically outlined
in these Directions for Use. Any use of this product inconsistent
with the Directions for Use is at the discretion and is the sole
responsibility of the practitioner.
2. DO NOT look directly at the light emitted from the curing probe.
As with any bright light source, staring directly at the source
may cause temporary effects such as after-image. Use provided
light shield to decrease light exposure and after-image. (See
Warnings)
3. It is recommended that all curing light users and patients
employ suitable eye protection during operation of the
SmartLite iQ2 unit. (See Warnings)
4. Persons who have had surgery for eye cataracts are especially
sensitive to light and generally should not use or be exposed to
the SmartLite iQ2 unit unless they employ suitable protective
measures. These measures should include the use of spectacles
that filter out blue-violet and ultraviolet light. (See Warnings)
5. Safety of the SmartLite iQ2 unit has not been established in
people who have been fitted with an implanted heart pacemaker
and have been cautioned against the use of small electrical
appliances (such as electric shavers, hair dryers, etc.). In these
cases we recommend that the SmartLite iQ2 unit not be used.
6. DENTSPLY Caulk provides light probes suitable for use with the
SmartLite iQ2 unit. Other light probes are used at the discretion
and sole responsibility of the practioner.
7. Curing probes are designed with a protective outer coating to
prevent light from escaping through the external probe surface.
Probes that are scratched or damaged in any way should not
be used. Probes are made of fiberoptic glass and may be
damaged if dropped or mishandled.
8. Curing Probes must be maintained in a clean, undamaged con-
dition. A contaminated or chipped/scratched tip will reduce the
effectiveness of the unit by reducing the amount of transmitted
light. Refer to cleaning/disinfection/sterilization instructions and
radiometer sections.
9. Check unit for adequate light output before each procedure.
Failure to verify output may allow inadequate curing. (See
Radiometer Operation)
10. DO NOT IMMERSE UNIT IN WATER OR DISINFECTANT. Wipe,
do not spray solution onto plastic parts. Prevent liquids from
entering openings on unit, especially the socket for the
fiberoptic probe. Always wipe the unit with the fiberoptic probe
installed.
11. Should the SmartLite iQ2 unit become damaged in any way,
do not attempt to operate the unit unless thoroughly inspected
and serviced by qualified DENTSPLY Service personnel.
ADVERSE REACTIONS
1. Prolonged unfiltered exposure to the light source may cause
damage to the eye. (See Warnings)
2. Prolonged contact with soft tissue may cause injury or irritation
to the tissue. (See Warnings)
3. Medical conditions such as solar urticaria, erythropoietic
protoporphyria or cataract surgery may be aggravated by
exposure to emitted light. (See Contraindications, Precautions)
4. Electrical appliances can interfere with some cardiac
pacemakers. (See Precautions)

Charging Base
1. Align the probe with the socket of the handpiece and insert until
it is seated fully and snaps in place (Figure 1). (To remove an
attached probe, grasp it at the base near the handpiece and
pull firmly but carefully until it releases from the socket.) Slide
the light shield over the probe onto the chuck on the nose of
the handpiece (Figure 2).

2. Plug the detachable power supply plug into the receptacle on
the back of the charging base (Figure 3). The power supply plug
may now be plugged into an AC supply. The power indicator
light on the charging base (Figure 3) will illuminate (green) if
power is available for charging.

3. Place the handpiece onto the charging base so that the
recharging pins on the charging base make contact with the
charging pads on the bottom of the handpiece (Figure 4). The
battery indicator light on the handpiece will illuminate green if
the handpiece is placed in the charging base properly.

If the battery indicator light does not illuminate, check for proper
placement of the handpiece on the charging base. If proper con-
tact is NOT made between the handpiece and charging base,
error code E2 (see Errors) will appear on the LCD screen.
NOTE: Allow the handpiece to charge for at least 2 hours before
first use.
HANDPIECE STATES
The SmartLite iQ2 unit handpiece has five general states that will
affect display modes and functions.
1. Ready State: The handpiece is removed from the charging
base and is ready to operate.
2. Sleep State: If the handpiece is off of its charging base (or if
the power is interrupted to the charging base while the hand-
piece is on it) for more than ten (10) minutes, it automatically
powers down into a "sleep" state in order to minimize battery
drain.
3. Curing State: The handpiece is removed from the charging
base, the curing LED has been activated and is in a curing cycle.
4. Charging State: The handpiece is properly placed on a
powered charging base.
5. Error State: In the event of a malfunction of the device, the
LCD will show an error code (e.g. "E1") in place of the curing
mode indicator. In an error state the activation or function
buttons will not operate. (Please see Errors section for more
information.)
OPERATION
The SmartLite iQ2 unit will initiate polymerization (curing) of
materials that are activated by photoinitiators with a maximum
absorption in the wavelength range between 450-475nm (typically
camphorquinone).
NOTE: Light curing times for most DENTSPLY restorative
and preventive materials may be reduced from
standard curing times noted in the materials
Directions for Use. Minimum recommended curing
times for the SmartLite iQ2 unit are provided on
the DENTSPLY VLC Materials Curing Guide
provided with the light.
