Effect of light curing units on the polymerization of bulk fill resin-based composites

The manufacturers of bulk fill resin-based composites (RBCs) claim that it possible to successfully photo-cure 4 or even 5-mm increments of RBC instead of the customary 2mm increment. While this approach may introduce less voids between each increment and reduce overall treatment times, the ability to adequately photo-cure such a large volume of RBC in one exposure is a concern.
