A dental curing light is a piece of dental equipment that is used for polymerization of light cure resin based composites. It can be used on several different dental materials that are curable by light. The light used falls under the visible blue light spectrum. This light is delivered over a range of wavelengths and varies for each type of device.
In the early 1960s the first light curing resin composites were developed. This led to the development of the first curing light. The first dental curing light, called Nuva Light, was developed by Dentsply/Caulk in the 1970s.Ultraviolet light used as a catalyst in the polymerization of Nuva-seal, a bonding agent used as an enamel sealant.
In about 1971, John Brownbill was the first dentist in Australia placing fissure sealants. He used ultraviolet light for setting the resin.
