Evaluate the influence of enamel-shade composite thickness on the overall color of aesthetic dental restorations

Composite materials are widely used in aesthetic dental restorations due to their advantages, including minimal invasive preparation, high mechanical strength, adhesive durability, biocompatibility, time and cost-effectiveness. This study investigates the effect of enamel-shade composite thickness on the final color values of restorations using a two-layer technique to replace enamel and dentine.
