利用荧光发射将复合树脂与牙齿区分开来，作为大规模牙科健康检查中树脂填充牙齿的视觉检测的基础研究。通过使用波长为 400 至 500 nm 的光激发，从提取的人上颌中切牙和 12 种光固化复合树脂（最多 15 个色度）中获取荧光光谱。对于所有树脂来说，树脂与牙齿的荧光强度比在 500 nm 左右最低。根据光谱结果拍摄荧光图像，这证实了树脂填充牙齿中树脂部分和牙齿之间的区别。
The differentiation of composite resin from teeth using fluorescence emission was investigated as basic research for the visual detection of resin filled teeth in mass dental health examinations. Fluorescence spectra were taken from extracted human maxillary central incisors and 12 types of light-cured composite resins with a maximum of 15 shades via excitation using light with wavelengths of 400similar to500 nm. The fluorescence intensity ratio of resin to tooth was lowest around 500 nm for all the resins. The fluorescent images were taken based on spectroscopic results, which confirmed discrimination between the resin part and the tooth in the resin filled tooth.
