This researcher worked with light sources that ranged from conventional, filtered quartz-tungsten-halogen and filtered plasma-arc lights, to high intensity violet, UV, and blue LEDs.

Some of these lights use glass-fibered light guides, while others emit light from an LED either through a lens or through a protective clear or frosted plate.

This nonuniformity causes uneven curing of the resin or epoxy material, weakens that material, and shortens the life of the dental repair.
