Abstract
A system for identification of hue and lightness of dental products formed from dental material within enclosures comprises an alpha series of at least three caps (A) having an alpha cap hue and supported by enclosures enclosing dental materials which are polymerizable to form an alpha series of dental products having an alpha product hue. The system includes a beta series of at least three caps (B) having a beta cap hue supported by enclosures enclosing dental materials which are polymerizable to form dental products having a beta product hue. The system includes a first series of at least three caps (1) having a first cap lightness and each of said first caps being supported by an enclosure enclosing a dental material which is polymerizable to form a dental product having a first product lightness. The system includes a second series of at least three caps (2) having a second cap lightness, and each of said second caps being supported by an enclosure enclosing a dental material which is polymerizable to form a dental product having a second product lightness.
