Abstract:Dental caries is the infectious oral disease affecting people worldwide. Early dental caries detection helps to prevent caries progression by non-surgical methods and promote tooth remineralization. A simple method based on laser induced fluorescence spectrum with backscattered enhancement is proposed for the detection of initial caries on vitro teeth. Fluorescence spectra of carious erosion on different status were given. The radiation of backscattering, reflection and autofluorescence from teeth was register… Show more
