Abstract

A method for obtaining an image of tooth tissue directs incident light toward a tooth (20), wherein the incident light excites a fluorescent emission from the tooth tissue. Fluorescence image data (50) is obtained from the fluorescent emission. Back-scattered reflectance image data (52) is obtained from back-scattered light from the tooth tissue. The fluorescence and back-scattered reflectance image data are combined to form an enhanced image (64) of the tooth tissue for caries detection.
