Özet:

Light devices are used for polymerization of composite resins hardened by visible light. There was a variety of light devices that were released on the market as well as the content of composite resins. The technologies and techniques used to reduce the time of application and increase the amount of polymerization are changing over time. From the first developed ultraviolet lighting device to the present day; various types of light sources have been developed, including quartz tungsten halogen lighting devices (QTH), light emitting diodes (LED), plasma arc lighting devices (PAC), argon laser lighting devices. The purpose of this collection is to provide information on the characteristics of the light devices used today, the working principles and the polymerization activities in the light of current studies. Keywords: Halogen Lighting Devices, Lighting Devices, Laser, LED, PAC Abstract Light curing units are used polmerization for light-cured composite resins. Content of composite resins as well as light curing device has been varied. Using technologies and techniques to reduce the time application and increase the amount of the polimerization has changed over time. From the first developed device ultraviolet up to the present, quartz-tungsten-halogen light-curing units (QTH), light emitting diode (LED), plasma arc light devices (PAC), argon laser light devices have been developed, including different types of light sources. The aim of this review is to present the properties of the light equipment, working principles and in the light of recent studies provide information about the activities of polymerization.
