light pol·y·mer·i·za·tion

(līt poli-mĕr-ī-zāshŭn)
Use of visible or ultraviolet illumination to excite a photoinitiator; which can initiate polymerization, usually of a resin.
Synonym(s): light curing.

A major advantage of thermal imaging during light curing is to give information about the cooling time of the pulp space to initial temperature values.
As well, Bulk Fill composites presents a specific photoinitiator and this determines the power and time of light curing; because in each one the spectrum of light absorption differs.
Many attempts have been made to improve the degree of conversion and depth of cure for photopolymerized cements by improvements in size of the filler particle, color, incremental technique, saturation, shades, photo initiator, number of firing cycles and distance of light curing tips.10
The light curing process looks quite simple, and indeed it is.

Results showed that MSB of metal brackets cured at 0mm and 5mm light curing tip distance was similar.
Light-cured adhesive is relatively easy to use in an assembly process, even though it involves a light curing step.
The objectives of this study were (1) to measure the temperature increase induced during thermocure lamp setting reaction of an GC and compare it with those induced by visible light curing of an RMGIC and an PMCR and (2) to compare temperature increases in primary and permanent teeth during setting and curing of these three materials.
"The problem with this approach was that, although the parts to be bonded are visually clear, the material has UV absorbing properties- so getting the right amount of light curing energy to the joint appeared to be tricky."
The use of light-transmitting posts in conjunction with light-curing composite resins within a post canal space eliminates the difficulty in control experienced with a rapidly polymerizing autocuring composite resin and ensures complete polymerization in a light curing composite resin.
