Masking Ability of the Combined Application of Opaquers and Resin Composite on Discolored Backgrounds.

The aim of this study was to evaluate the masking ability of a combined application of opaquers and resin composite over discolored backgrounds: A3, A3.5, C2, C3, and C4. The groups were divided according to the opaquer brand, the number of opaquer coats (one or two), and the thickness of the resin composite layer (0.

Masking ability of bleach-shade resin composites using the multilayering technique.

Objective: Evaluate the masking ability of bleach-shade resin composites applied by multilayering techniques over colored substrates.

Materials And Methods: Disc-shaped specimens were fabricated from bleach-shade resin composites using different multilayering techniques. Substrates were produced in opaque ceramic discs simulating colored substrates (A2, A3, A3.
