Color changes in resin cement polymerized with different curing lights under indirect restorations.

Aim: The aim of the study was to investigate the effects of different interface materials and curing units on color changes in a resin cement material.

Materials And Methods: Three interface materials and different curing systems, quartz-tungsten-halogen and polywave and monowave light-emitting diode (LED) light curing units, were studied at two-time intervals. Polystyrene strip was used as a control group.
