Figure 2 Sixteen types of dental images from the shade guide reference. The VITAPAN classical A1–D4 shade guide (Internationally established dental shade guide commercial product). The arrangement of the shades in the VITAPAN classical family of shades is as follows: A1–A4 (reddish-brownish hue). B1–B4 (reddish-yellowish hue). C1–C4 (greyish hue). D2–D4 (reddish-grey hue). Chroma is designated with numerical values 1, 2, 3, and 4.
