Brief Summary
Light curing cements used for laminate veneers may be not totally cured in certain areas, so dual cured resin cements may solve this problem yet the dual cured cements containing amines cause yellowish discoloration of the veneers after time. A new dual cured cement which is amine free is introduced so the investigators have to try it clinically using parallel groups in randomized clinical trial.
