A maxillary right central incisor resin tooth was used to prepare anatomic-contour crown-shaped zirconia specimens. A3-shade and high-translucency zirconia blocks were selected and milled. The crowns were assigned to three different liquids, namely cola drink, orange juice, and red wine, in groups of ten. Each specimen was measured three times and the color difference (ΔE) was calculated. Zirconia showed significant discoloration in all dietary colorants when compared to control group. The highest ΔE observed was with red wine, whereas orange juice showed the lowest one.系所名稱：數位口腔工程產業碩士專班thesis
