Abstract
Abstract A tooth color shade guide which has a body (20) constructed from photographic paper, thermoplastic, or cardboard, having a number of fingers (22) distending from a base portion (28). A specimen (32) of a color shade is located on the end of each finger, each having a different hue and alpha-numeric designations (34) adjacent thereunto allow natural tooth color to be matched and identified. The attaching end (26) of the fingers are perforated (30), permitting them to be individually torn-off for comparison and then the entire color shade guide may be disposed of after use. A visual indicating surface (38) may be added to the fingers that is light sensitive and changes color in a few minutes after exposure. This surface (38) has a message imprinted in writing indicating the guide has been used preventing cross-contamination with other patients. Alternately, a moisture indicating surface (39) may be added to the back of each finger exhibiting use by changing color when in contact with moisture present in a persons mouth.
