Abstract

Detailed measurements of the color of the maxillary anterior teeth of young men and women were examined in CIE1976 (La*b*) Color Space by using the spectroradiometer (Photo Research Co., Pritchard Model 1980B) to clarify color of the natural teeth. As a result, the following conclusions were obtained.<BR>1. The spectral distribution range under Illuminant D65 was as follows: L*(metric lightness) 52.3-80.3, Cab*(metric chroma) 2.9-28.1 and Hab°(metric hue-angle) 55.2-94.3°.<BR>2. As for the differences by type of tooth, they were as follows:<BR>With regard to L*, at the middle, central incisor>lateral incisor>canine.<BR>With regard to Cab*, at the middle, canine>central incisor-alateral incisor.<BR>With regard to Hab°, at the middle, central incisor>lateral incisor≡acanine.<BR>3. As to the difference by region, regarding L* apart from the fact that no significant difference was observe in women's canine between the cervical and the middle, middle>cervical≡aincisal in both men and women.<BR>With regard to Cab*, cervical>middle>incisal.<BR>With regard to Hab°, incisal*amiddle>cervical.<BR>4. On the whole, no difference by sex was noted.
