IDENTIFICATION OF EQUIPMENT
Curing light (optional item) – Features of the product:
The Curing Light belongs to the newest generation of LED photo-activation devices. This
abbreviation stands for Light Emitting Diode, a totally different type of light emission, if
compared to conventional halogen equipment.
Unlike traditional devices, which generate wide-spectrum light and heat, this technology
uses a cold light of the precise wave length needed to activate various dental products.
LED technology, which was recently introduced in Dentistry, brought about several useful
features to those light-curing devices used in composite resin restoration. Besides being
more durable, LED technology turned devices more compact, ergonomic and easier to install
and transport. The emission of cold light within a precise wave length range ensures the
safe cure of camphorquinone-activated composites, preventing dental heating, pulp damage
or discomfort for both patient and dentist. Although being relatively new, this technology
is nowadays in its second generation. LED safety and efciency, now allied to high-energy
emission, are available to all clinic procedures which require light-curing power, including
bleaching treatments.
The light of 440nm-460nm wave length, allied to the high energy emitted by Curing
Light, makes possible the multi-functionality of this device:
- Direct restoration procedures: composite resins, ionomers and adhesives.
- Indirect restorations: adhesive cementation of laminates, inlays, esthetic pins and
metal-free crowns.
- Dental Bleaching: activation of bleaching gel and polymerization of gingival barriers.
Compatible with 35% hydrogen peroxide-based bleaching gels.
- Attachment of braces and orthodontic accessories.
- Activation of light-cure materials, such as sealants, surgical cements and covering
bases.
Designed and built with cutting-edge technology, it meets the highest standards specied
by world’s dental authorities.
Operation control display in handpiece, sound alarm with beep every 10 seconds and 4
beeps at the end of the cycle.
Advantages offered by Curing Light:
- More spectrally-selective light than conventional lamps.
- Cold light, it doesn’t heat up the resin nor the tooth.
• Light compact equipment that provides handling comfort.
• Low power consumption.
• Longer useful life of the light emitting diode (equivalent to 36.000.000 cycles of 10
seconds).
• It does not use optical lter.
• It does not require forced ventilation, thus avoiding noise emission.
We noted that the light emitted by the Curing Light is completely contained within the
absorption interval of the photo starter, therefore it’s 100% used, whereas the conventional
equipment running on halogen lamps has non-used wave-length regions.
The Curing Light doesn’t generate heat since it uses light emitting diodes.
The light conductor is removable, made out of high resistance polymer and of easy
maintenance.
