several generations of led (light-emitting diode) light-curing units have been introduced over the last few years. the 1st-generation led lights generally were low in intensity and did not cure materials completely. the diodes were designed to activate cq (camphorquinone) initiator around 460 nm. however, alternative photo-initiators used in bleach shades and incisal (translucent) shades of composites and in sealants and bonding agents are not activated by these “blue-light” units. the 2nd-generation led light-curing units (bluephase, elipar freelight 2, l.e. demetron 1, radii, allegro, smartlite iq, the cure) have a single, high-powered diode with multiple emission areas. these units have a large surface area of emission and high-energy output. the 3rd-generation led light-curing units (ultralume 5) have two or more diode frequencies and emit light in different ranges to activate cq and alternative photo-initiators. while most dentists are still using quartz-tungsten-halogen (qth) light-curing units, the convenience of the led units is making them increasingly popular.
