Abstract
The tristimulus values of 180 extracted maxillary and mandibular anterior teeth were
measured by colorimeter. And it were colnverted to Munsell color order system(Hue,
Value, Chroma) and CIE L＊a＊b＊ color coordinates.
The commonly used Vita, and Bioform shade guides, 2 composite resin shade
guides(Prisma APH and Z-100), and a glass-ionomer shade guide(Fuji II) were
compared with these teeth.
At the middle facial surface, color distributions of teeth were Hue(0.56YR to 9.77Y),
Value(2.46 to 7.9), and Chroma(0.14 to 2.02). And the aberaged values and standard
deviations for L＊a＊b＊ were 63.18±10.44, 1.11±1.66, and 5.79±2.36.
The shade guide did not match well with the color space of the human teeth.
Especially, the lacks of the Yellow-red Hues and higher values were prominent.
Compare with other measurements, the Hues of the teeth measured in this study were
broadly distributed(most of ranges in Y and YR were included), While the Value and
chroma were shown to the lower
