Abstract

The goal of our study was to investigate the natural intrinsic fluorescence in human enamel and dentine and any correspondence of such autofluorescence to the results from electron scanning microscope studies about mineral and organic distribution in different tooth structures. Fluorescence spectra of sound enamel and dentin, illuminated with 337 nm nitrogen laser were recorded. The spectrum of sound tooth enamel consists of a broad band -- 490 nm maximum of fluorescence with one secondary maximum at 400 - 440 nm. The spectrum of the sound dentine has a maximum at 490 nm, like enamel spectrum but the peak at the 400 - 440 nm has intensity, comparable with the peak intensity at 490 nm. Distributions of elements -- Ca and P in area and line were obtained by the method of X-ray microanalysis. The images of the investigated surfaces as well as distribution of basic elements in the area were obtained.
