Effect of masking and bleach-shade composite resins on the color and translucency of composite restorations: an in vitro study

Incremental application of masking and bleach-shade composites significantly reduced translucency and enhanced masking ability. The SW group showed the most favorable outcomes, particularly against black and gray backgrounds. However, most specimens did not achieve clinically acceptable thresholds. Clinicians should consider both translucency and masking properties when selecting composites for esthetic restorations over discolored substrates.
