Abstract
A method for obtaining an image of tooth tissue directs incident light toward a tooth (), wherein the incident light excites a fluorescent emission from the tooth tissue. Specular reflection of incident light from the tooth tissue is reduced. Fluorescence image data () is obtained from the fluorescent emission. Back-scattered reflectance image data () 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 () of the tooth tissue for caries detection.
