Comparison of quartz-tungsten-halogen, light-emitting diode, and plasma arc curing lights
PURPOSE: This study determined which light source was best at photopolymerizing five representative brands of resin composite. The hypothesis was that there would be no difference in the hardness of the composites when ...
The effect of distance from light source on light intensity from curing lights
PURPOSE: To investigate how light intensity changes as the distance increases from the tip of the light guide. MATERIALS AND METHODS: Ten different curing light/light guide combinations were used. Light intensity was ...
