ABSTRACT:
The invention relates to a computer readable medium comprising one or more programs for carrying out a method for determining a patient's tooth shade. The method generally includes the steps of generating an image of a patient's tooth wherein the image includes color information representative of the patient's tooth shade; storing color information representative of a plurality of tooth shades; and comparing the color information of the image with the stored tooth shade color information to identify one or more tooth shades having a combined color that corresponds to the patient's tooth shade, and the color information that is obtained may be displayed to identify one or more tooth shades having a combined color corresponding to the determined tooth color. Preferably, the displayed data includes RGB chromaticities of the color image, and the patient's tooth color is determined by averaging the color information at selected locations of the image which correspond to different spatial locations of the patient's tooth. If desired, the color information of the patient's tooth can be electronically stored for use at a later time.
