Abstract

The corrected emission and excitation spectra of human and bovine dental enamel and its separated organic material were determined at room temperature and liquid nitrogen temperature. In both materials three distinctluminescence peaks were found in the region 350–360 nm, 405–410 nm, 440–450 nm. The intensity ratios of the peaks of the enamel do not differ substantially upon removal of the inorganic component. Hence a conclusion is confirmed that the organic component is the most responsible material for the total luminescence of the enamel. Several hypothesis are available for determination of the nature of luminescence of the organic components. Differences in the excitation spectra are discussed. Phosphorescence emission and phosphorescence lifetimes were determined.
