It was aimed to evaluate the effect of various surface-conditioning methods on the translucency and color properties of resin-matrix ceramics (RMCs) with different types and thicknesses. Rectangle-shaped RMCs were prepared from Voco Grandio, Brilliant Crios, Lava Ultimate, GC Cerasmart, and Vita Enamic blocks at 0.5 and 1.0 mm thicknesses. Specimens were divided into four groups control, airborne-particle abrasion (APA), 2 and 3 W Er, CrYSGG laser irradiations (L , L ) (n = 15). The color values of specimens were recorded before and a
