Abstract

The purpose of this study was to determine the effect of opaque shades on the color of layered resin composite restorations. The materials used were opaque-A2 and Body-A2shades from FiltekTM Supreme (3M ESPE)(FS) and Gradia Direct (GC)(GD). L*, a*, and b* of the layered resin composites (1mm of body shade on 2mm opaque shade or1mm of body shade on 2mm body shade) were evaluated using a colorimeter on a black backing. When the opaque shades were used, L* and b* of FS and a* and b* of GD showed higher values compared with not using opaque shades. Therefore, usage of the opaque shades could be beneficial to obtain higher brightness and chroma in the layering technique of composite resin restorations.
