研究了基于405 nm激发波长的光诱导自体荧光光谱的比色参数用于龋病分期的可行性。对国际龋病检测与评估系统分类的4组牙样(10个健康牙样、10个早期龋齿标本、14个已建立龋齿标本和10个重度龋齿标本)进行了体外荧光光谱测试。龋损样本在627 nm附近有一个额外的荧光峰。建立并计算了荧光光谱与人体颜色知觉之间的数学关系。随着严重程度的增加，根据CIE 1931(x，y)色度坐标和主导波长的色度参数，荧光颜色从绿色变为黄色。主波长的单因素方差分析结果显示，4个分类组之间的差异有统计学意义。光诱导荧光光谱的比色参数可以潜在地应用于评估各种龋齿水平。
The feasibility of colorimetric parameters for the discrimination of the stages of dental caries based on a light-induced autofluorescence spectrum at a 405-nm excitation wavelength was investigated. The fluorescence spectra of 4 groups of tooth samples (10 sound, 10 early-stage decay, 14 established decay, and 10 severe decay), which were classified by the International Caries Detection and Assessment System, were experimentally measured in vitro. The carious lesion samples had an additional fluorescence peak at around 627 nm. The mathematical relation of the fluorescence spectrum and human color perception was established and computed. With increasing severity, the fluorescence color changed from green to yellow according to the colorimetric parameters of the CIE 1931 (x, y) chromaticity coordinates and dominant wavelengths. The results from a one-way ANOVA of the dominant wavelength showed a statistically significant difference among the 4 classified groups. The colorimetric parameters of the light-induced fluorescence spectrum can potentially be applied to evaluate the various carious levels.
