Abstract- In the last few decades' restorative dentistry has undergone an exponential evolution. This evolution allowed the development of restorative composite materials with excellent physical properties, chemical properties, and better clinical performance. Recently, light curing dental composites are extensively used in restorative dentistry. It is a piece of dental equipment that was introduced to restorative dentistry. It initiated photo polymerization reaction of composites resins. It is used on different dental materials that are curable by light. The light falls under the visible blue light spectrum. This light has a range of wavelengths and different between each type of device. There are four basic types of dental curing light sources: tungsten halogen, light-emitting diodes (LED), plasma arcs, and lasers. The two most common are halogen and LEDs. LED curing lights impact and develop the photo polymerization of composites resins. At this research we will study the comparative evaluation of depth of cure in dental composites after using LED light curing unit of two different intensities.
