Abstract

In the present work we report the results of the measurement of the angular distribution of laser light reflected from a rough tooth surface and of Monte Carlo simulation of the 3-D process of photons migration in a two-layered human enamel- dentin structure. The measured reflected patterns are as a whole asymmetric and more spread than the calculated by the simulation. The measured total diffusely reflected power reaches 3 - 20% from the irradiating power. An increase in the total absorbed energy as well as in the spread of absorption is observed below the enamel-dentin interface. The scattering anisotropy affects in a different way the absorption below the tooth surface: the highly forward peaked phase function leads to decrease of absorption just below the air-enamel boundary and rise of absorption below the enamel-dentin boundary.
