Abstract:Dental curing light is a device that facilitates polymerisation in light cure resin based composites. Dental curing light polymerizes different materials that are curable by light. Due to the increase in need of Resin based composites with improved physical properties having less stress and marginal interface, recent advancements in light cure led to the introduction of Fourth generation LED, Organic LED and Quantum dots. Scanwave-MiniLed is the first fourth generation LED that can minimize heat effects thereby preventing the hotspots. Organic LED works on electric current wherein there is a formation of organic layer between the two electrodes. Organic LEDs can evenly irradiate all surfaces of photopolymerizable impression trays. Organic LEDs can cause photoinitiation in photocurable impression material, whose applications are Vital bleaching and veneer cementation. Quantum dots,on the other hand, are incorporated into photopolymerizable resin composite from where it allows curing from within. Transition of electrons from valence band to conduction band can cause photoinitiation and since the fluorescent properties of quantum dots closely match that of the natural human teeth, quantum dots are considered to have a good biocompatibility.Manufacture of Organic LEDs with flexibility, transparency and low energy light curing procedures and also quantum dot nanoshells in LED Light cure are the future scopes of this study.Hence, this study reviews the role of organic LED and quantum dots in light cure.
