英文摘要
Human teeth fluoresces as a result of illumination by UV-light.The fluorescence characteristics of human teeth were investigated with respect to aging and caries by microscope fluorometry.To measure nanosecond decay features of tooth fluorescence,a microscope fluorometer equipped with an air-discharge pulsed lamp and a Xe pulsed lamp was devised.A fiberscope fluorometer was also devised to apply the time-resolved fluorometry into clinical inspection of human teeth.The fluorescence intensity and fluorescence decay curve were found to be age dependent in dentine tissue.The fluorescence intensity and fluorescence decay curve of caries enamel were similar to those of hydroxyapatite than the sound enamel.The data suggest that both quantitative and qualitative changes in the organic matrix of tooth tissue may affect its fluorescence characteristics.
