Effect of thickness on color and translucency of a multi‐color polymer‐infiltrated ceramic‐network material

Objectives To evaluate the effect of thickness on color and translucency of a multi‐color polymer‐infiltrated ceramic‐network (PICN) material. Methods Specimens of 0.5, 1.0, 1.5 mm thicknesses were obtained by sectioning VITA ENAMIC® multiColor (E‐MC) High Translucent CAD‐CAM blocks (1M1‐HT, 1M2‐HT,...

Description
Summary:Objectives To evaluate the effect of thickness on color and translucency of a multi‐color polymer‐infiltrated ceramic‐network (PICN) material. Methods Specimens of 0.5, 1.0, 1.5 mm thicknesses were obtained by sectioning VITA ENAMIC® multiColor (E‐MC) High Translucent CAD‐CAM blocks (1M1‐HT, 1M2‐HT, 2M2‐HT, 3M2‐HT, and 4M2‐HT). Spectral reflectance and color coordinates were measured on white and black backgrounds using a spectroradiometer, CIE D65 illuminant and CIE 45°/0° geometry. CIEDE2000 color and translucency differences (ΔE00 and ΔTP00) between thicknesses and adjacent layers were evaluated using their respective 50:50% perceptibility and acceptability thresholds (PT00 and AT00). Results In general, ΔE00 between thicknesses for all shades and layers were above AT00 in general. Chroma decreased from cervical to incisal layers with statistically significant differences (p
