The VITA classical A1 – D4 shade guide serves to accurately determine tooth shade.
The arrangement of the shades in the VITA classical family of shades is as follows:
A1 - A4 (reddish-brownish)
B1 - B4 (reddish-yellowish)
C1 - C4 (greyish shades)
D2 - D4 (reddish-grey)
Hold the shade guide at a distance of approx. 25-30 cm (arm bent) from the patient’s tooth.
Decide quickly on the shade by comparing the shade samples of groups A – D with the natural tooth.
Disinfect the shade guide after each shade determination.
Tips for determining shade
Determine tooth shades as much as possible under natural daylight and daylight lamps and not under typical indoor lighting conditions. The surrounding colors should be as neutral as possible.
Ask patients toremove any lipstick or cosmetics which could have an influence on shade determination.
Cover up bright clothing with a gray cape.
Hold the shade sample tooth as close to the patient's tooth as possible.
When choosing the shade, only the middle area of the shade sample tooth should be observed. Make your choice quickly and always accept your first decision, since the eyes begin to tire after approx. 5-7 seconds.
