title: LED's--future technology in curing scenario?--an in-vitro study.
abstract: The long term clinical success of composite restoration depends upon appropriate curing light sources. This in-vitro comparative study investigates the influence of conventional halogen and light emitting diode curing sources on the surface hardness, depth of cure and polymerization shrinkage of composites specimens of 8 mm diameter and 10 mm in height were used to study the depth of cure. Specimens of dimension 8.6 mm in diameter and 2 mm in depth were used to measure the surface hardness and polymerization shrinkage. The results showed that in the long run LED's seem to have great potential to achieve a clinically consistent quality of composite cure.
