✦ Synopsis

Laser induced autofluorescence spectroscopy of enamel and teeth at different artificial demineralization stage irradiated by 403 nm semiconductor laser were investigated. The quantitative evaluation parameter of mineral content is built on the basis of the fluorescence characteristic spectrum of 443 nm and 526 nm ratio to the total fluorescence integral. In the end, the dependence of characteristic spectrum on the excitation light power was experimentally investigated. The results reveal that at least 10 mW power is necessary to stimulate the featured spectrum.
