Abstract
A method for determining a patient's tooth shade, by generating an electronic 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. the image of the patient's tooth and the stored tooth shade color information are electronically displayed in color to enable a viewer to comparatively determine the color of the patient's tooth shade. Preferably, the patient's tooth shade is determined by selecting portions of the electronically displayed image of the tooth; determining the color of the selected portions; and comparing that color information with the stored tooth shade color information to determine the color of that portion of the patient's tooth. The selection of portions of the tooth is generally repeated until a tooth shade color is determined for all spatial locations of the image of the patient's tooth.
