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.

为了测量牙齿荧光的纳秒衰减特性，利用显微荧光技术研究了牙齿老化和龋齿的荧光特性。设计了空气放电脉冲灯和Xe脉冲灯相结合的显微荧光测定仪，并将时间分辨荧光测定仪应用于临床牙体组织的检测，发现牙本质组织的荧光强度和荧光衰减曲线具有年龄依赖性。龋牙釉质的荧光强度和荧光衰减曲线与羟基磷灰石相似，而不是纯牙釉质。结果表明，牙组织有机基质的定量和定性变化都可能影响其荧光特性。
