Light curing

Abstract

The debate regarding composite resin’s shorter than expected service life is ongoing. The properties of this restorative material seem to only have a minor effect on restoration longevity, and the major reasons for failure can be attributed to the patient and the skills of the operator. Inadequate light curing (photopolymerisation) of the resin is also an important contributing factor in less than optimal patient outcomes involving posterior resin composite restorations.
