Abstract
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.

A system for identification of hue and lightness of dental products formed from dental material within enclosures, comprising: 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 a first product hue, 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, 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, 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, said beta cap hue being more reddish-yellow than said alpha cap hue, said beta product hue being more reddish-yellow than said alpha product hue, said alpha cap hue being more reddish-brown than said beta cap hue, said alpha product hue being more reddish-brown than said beta product hue, said second cap lightness being darker than said first cap lightness, said second product lightness being darker than said first product lightness the difference in hue between said alpha cap hue and said beta cap hue being substantially greater than the difference in hue between said alpha product hue and said beta product hue, and the difference in lightness between said first cap lightness and said second cap lightness being substantially greater than the difference in the lightness between said first product lightness and second product lightness.
Claim 3
Dependent Claim
74 words
The system of claim 1 further comprising a chi series of caps (C) having a chi cap hue and supported by enclosures enclosing dental materials which are polymerizable to form a chi series of dental products having a chi product hue, and wherein the difference in hue between said alpha cap hue and said beta cap hue is greater than the difference in hue between said alpha product hue and said chi product hue.
Claim 4
Dependent Claim
79 words
The system of claim 2 further comprising a third series of caps (3) having a third cap lightness, and each of said third caps being supported by an enclosure enclosing a dental material which is polymerizable to form a dental product having a third product lightness, and wherein the difference in lightness between said first cap lightness and said second cap lightness is greater than the difference in lightness between said first product lightness and said third product lightness.
Claim 5
Dependent Claim
13 words
A system of claim 1 wherein said alpha cap hue is reddish brown.
Claim 6
Dependent Claim
131 words
The system of claim 4 wherein each said enclosure comprises a miniature cartridge, having: a hollow elongated generally cylindrical body having an inner wall with a substantially uniform diameter, said inner wall enclosing dental material in a chamber, one end of said body being open and formed at the extremity thereof with an annular circular exterior flange, the opposite end of said body being closed by an end wall, said dental material being adapted to form a dental product having a characteristic shade, said body having an outer surface with an alphanumeric indication of the said shade, a discharge integrally connected to said body and having a passageway therethrough extending from said chamber at said closed end of said body to facilitate discharge from the cartridge, said nipple having a wall.
Claim 7
Dependent Claim
13 words
The system of claim 1 wherein said beta cap hue is reddish yellow.
Claim 8
Dependent Claim
13 words
The system of claim 1 wherein each said chi cap hue is gray.
Claim 9
Dependent Claim
58 words
The system according to claim 7 further characterized by said body and piston being formed from plastic material suitably colored to render the same impervious to the transmission of ambient light, thereby rendering the cartridge adapted to contain light-curable material and the like in a manner to prevent premature curing of such material while stored in such cartridge.
