![]() Commercial LED curing units were used as a control. In the current research, CAD (computer-aided design)/CAM (computer-aided manufacturing) assisted solid-state lasers were employed for curing of different dental restorative composites consisting of micro- and nanoparticle-reinforced materials based on acrylic resins. Recently, with regard to the radiation in the blue region of the spectrum, powerful solid-state lasers have been commercialized. However, a widespread clinical application of this kind of laser remains difficult due to cost, heavy weight, and bulky size. Whereas laser curing is not dependent on the distance between the curing unit and the material, such distance represents a drawback for conventional curing units. ![]() Over the last three decades, it has been frequently reported that the properties of dental restorative composites cured with argon laser are similar or superior to those achieved with conventional halogen and light emitting diode (LED) curing units.
