Increase of in vitro curing depth of class II composite resin restorations.
Simulated class II cavity preparations were made in black Plexiglas acrylic, and various posterior composite resins were placed in the preparations and cured with and without a transparent cone-shaped "Light-tip" device. The transparent Light-tip device improved the curing depth approximately 2.2 mm, and this ability to illuminate the deeper portions of the restoration increases the potential to improve the curing of composite resin.
