AB -  Dental light-curing units are devices that emit light within a specific wavelength for the purpose of curing or hardening resin-based restorative materials. In the most frequently used light-curing units, the light is generated by a halogen bulb and boosted by a reflective mirror attached to the bulb. An internal filter then filters the light, and the blue portion of the visible light spectrum is emitted through the unit’s tip. Other light-curing devices include argon laser curing units, plasma arc curing units, and most recently, blue light emitting diodes (blue LED). exposed to light in a specific wavelength, initiate a chemical reaction (polymerization) that ultimately leads to the set or cure of the material. Light-cured resin-based composite restorative materials, for example, are soft and putty-like before curing and hard and rigid after curing. This enables the dentist to insert the unset composite material in the tooth before hardening the material with the curing light. Many laboratory-fabricated ceramic restorations, such as porcelain veneers and small inlays, can be bonded to tooth preparations with light-cured resin-based adhesives and composite cements. It should be noted that the light emitted by light-curing units can be harmful to the eyes when looked at directly.
