[Analysis of chromatic value of gingival porcelain].
OBJECTIVE
To study the distribution of the chromatic value of gingival porcelains.


METHODS
The color change of Shofu VINTAGE and Vita VMK95 gingival porcelains on the black and white backings was determined with a spectrophotometer (PR-650).


RESULTS
The results showed that the chromatic value of gingival porcelains was different on varying backings. The color space of gingival porcelain was L*: 41.85 - 50.64, a*: 12.46 - 19.46, b*: 1.33 - 4.62.


CONCLUSIONS
The chromatic value distribution cannot cover the color region of natural gingiva.
