1. Introduction and General Information
Introduction
The Kreativ Kuring and Bleaching Center is a high-intensity, filtered light
source and optical delivery system. It produces curing light for photoactivated dental composites (400-505nm), and photo-activated bleaching
formulations (400-545nm) at four times the rate of conventional light
systems. The Kreativ Kuring Light cures photo-activated dental materials,
such as those used in direct restorations, sealants, bonding agents, and
primers.

General Information and Features
The Kreativ Kuring Light offers the benefit of a rapid cure at a lesser
entry, operation, and maintenance expense than an argon laser. Kreativ
has developed a light source that combines long life and high lumen output
within the spectral bandwidths required for both composite polymerization
and power bleaching.
The unit uses a proprietary lamp to produce energy in the visible spectrum.
This light energy is passed through special dichroic band-pass filters that
pass energy in either the 400-505nm (composite curing) or 400-545nm
(power bleaching) range. This custom filtering delivers the bandwidth of
light matching the response curve for the photo-initiators in photocured
dental material or bleach activation.
Other features of the Kreativ Kuring Light include:

Consult the material manufacturer's instructions for the recommended
curing time.
Using the Mode Selection Keys, select the Mode you desire. Press the
footswitch to initiate the cycle. The unit will beep at the beginning and
every 5 seconds thereafter. The exposure time for the cycle is displayed in
seconds.
Normal Kure Mode
5 seconds
with the Kreativ Kuring Light equals
20 seconds
with a
conventional curing light.
Use the Kreativ Kuring Light for 5 seconds when the manufacturer's
recommendation is 20 seconds for the curing of a material. This timing is
achieved by releasing the footswitch when the first 5-second beep is heard.
10 seconds
with the Kreativ Kuring Light equals
40 seconds
with a
conventional curing light.
When the manufacturer's recommendation is 40 seconds for the curing of a
material, using the Kreativ Kuring Light for 10 seconds will equal a full
curing cycle. This timing is indicated by the second 5-second beep.
Boost Kure Mode
This mode increases the curing rate approximately 20% from Normal
Mode. This mode may be used when it is felt that extra power or faster
curing is required.
Ramp Kure™ Mode
This mode utilizes the microprocessor to “ramp’ the lamp power over a
specific time period. This type of curing process optimizes the physical
characteristics of the restoration by precisely controlling the rate of the
Page 15 990208 Rev D
Page 16
polymerization process. This reduces micro-gapping and shrinkage and
ensures the highest degree of polymerization possible.
Ramp Kure will work well with most common composites, but it has been
specifically programmed for Kreativ’s MicroFlow™ composite material.
Please contact your nearest authorized Welch Allyn / Kreativ service
representative for more information.
Bleaching Mode
Consult the manufacturer's directions for the appropriate activation time.
The Kreativ Kuring Light has wavelength limiting filters designed
specifically for photo-thermal accelerators, such as Kreativ’s PowerGel™
photo-specific bleach.
Kreativ PowerGel will give you the best bleaching results with your new
Kuring Light due to its photo-specific chemistry. It is the perfect
complement to your new Kuring Light.
Depress the footswitch to initiate the cycle. The unit will beep at the
beginning and every 60 seconds thereafter. The exposure time, in minutes
and seconds, is displayed.
Normal Bleach Mode
The Kreativ Kuring Light generally produces the same results as a
conventional visible light source in one-fourth (25%) of the time.
Boost Bleach Mode
This mode increases the light output power (i.e., photo-thermal energy)
approximately 20% above the Normal Bleach Mode. Use this mode when
extra power or faster activation is desired.
Comfort Bleach Mode
This mode provides a reduced lamp output from the Normal Bleach Mode.
This creates a slower photo-thermal activation of the bleach and may
increase the comfort of patients with certain types of sensitivity.
