Thermal modeling of laser destruction of hard tooth tissues

A numerical combined model with movable boundary conditions have been used for the evaluation of Er-laser dental treatments is presented. This model facilitates the simulation of heat flows and temperature distribution in different kinds of human teeth caused by Er-laser irradiation with arbitrary orientation of laser beam axis. This model can be used for simulation and optimization of exposure parameters to minimize pulp overheating and procedure duration in the application of lasers for dental treatment.
