Abstract:
OBJECTIVETo study the distribution of the chromatic value of gingival porcelains.
METHODSThe color change of Shofu VINTAGE and Vita VMK95 gingival porcelains on the black and white backings was determined with a spectrophotometer (PR-650).
RESULTSThe 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.
CONCLUSIONThe chromatic value distribution cannot cover the color region of natural gingiva.
