If the hue is red, the addition of white produces pink (bright); the addition of gray produces maroon (dull). Simple linear regression analysis showed a significant correlation of age with normalized grey value in association with the shade parameters. OPERATIVE DENTISTRY (MCQs) Model Paper 34. Natural teeth normally have many colors in them, with chroma gradi-ents from gingival to incisal that are missed by the simpler devices. Dental shade determination – The science of color. 3 The chroma of a natural tooth comes mainly from the dentin, and the thickness and opacity of the overlying enamel determines how much chromatic influence the dentin has. Both further steps, the determination of chroma and hue, reduce color-matching errors with a compliance of almost 70%[6,8]. 2 ' To facilitate communication with ceramists, the dentist should be thoroughly familiar with these terms and their definitions.

Munsell in 1898.2 Munsel’s three dimensions were hue (the basic color), chroma (the amount or density of a color), and value (the light-ness or darkness of a color). The lightest value level has only two chroma steps of single hue, and the darkest value level has three chroma steps of one hue. Chroma is the attribute that expresses the purity of a color.
