ABSTRACT:
A method and system for determining the color characteristic of a tooth, particularly in a mouth in which restorative dentistry is contemplated, employs the photographic imaging of the tooth of the patient, and the photographing of visually selected color standards, to achieve the final selection of the closest color match. The resulting photographic images, which may be on a single photograph, are subjected to calorimetric or spectrophotometric analysis to achieve the final selection of the closest match. The system avoids the need to rely upon the visual color acuity of the practitioner in order to achieve a close color match for a prosthetic device. Additionally, the method and system of the invention avoid the problems associated with color shifts associated with photography, when such is used alone as the indicator of tooth color.
