title: Effectiveness of reflective wedges on the polymerization of composite resins.
abstract: Polymerization of three composite resins was evaluated after they were light cured through one of four different reflective wedges. Other experimental variables were activation times and light units used. The same conditions were used for a control group, in which photoactivation was performed directly on the test specimens. Complete polymerization was never achieved when the curing light was directed through reflective wedges.
