Shade measurement was performed on the upper and lower anterior teeth of Japanese elderly, and examinations were conducted to identify a standard for the shade selection of dentures and partial dentures elderly Japanese patients. The subjects were 23 elderly Japanese dentulous people over 60 years old (mean age 68.4 ± 4.2 years), and 13 young Japanese people with teeth color deemed to be clinically norma (l mean age 21.6 ± 2.3 years). ShadeEye NCC (Shofu, Japan) was used for colorimetry. The measurement site was the upper and lower anterior teeth. Measurements showed a clear difference in the shade selected by the ShadeEye between the young and the elderly. In the elderly, C4 was determined to be the standard for upper and lower canines, C2 and C3 for upper and lower lateral incisors, and C3 for upper and lower central incisors. These results are thought to have implications for the effective selection of tooth shade in relation to tooth type among elderly Japanese.
