Light/Heating in tooth

Hi all! (Hi Ivar!)
I am currently trying to modelise the transformation of light into heat within a tooth. (You shine the tooth, and some light is transformed into heat by absorption)
I have succesfully succedeed to modelise that through absorption ans diffusion in the tooth, but my problem is to modelise the light coming on the tooth.
For the moment I have used a Dirichlet boundary condition saying I=Io on the surface, but it does not describe the propagation of the light through x and make the problem isotropic.
How would you modelise that incoming power propagating through x?
And I also have a second problem concerning the processing information. Indeed I need to know how much light has transformed intoheat, and so what I do is Heat= I in -Iout by doing an integration on the side of the tooth.
But it does not into account the reflexion/transmission, I would need only the transmitted power.
Any idea?
Cheers!
