Abstract
Directional dependence of reflected laser light and of the laser induced fluorescence signals performed both on the intact hard dental tissues, such as enamel, dentine, cementum and on the tissues pathologically affected by caries (superficial, intermediate and deep). The laser induced fluorescence spectra were collected at different angles of observation and were correlated with the different scattering and reflectance properties of the hard dental samples.
