Paper Abstract

Three dimensional model calculation on the basis of Finite Elements were carried out to simulate the heat distribution process under IR laser ablation. Several models were built up to study the time behavior of the heat stored in the walls of a laser induced crater. The time resolved data show a concentration of heat in the center of the crater and a strong thermal stress in the corner ring of the cylindrical crater. The results calculated for the thermal properties of dentine are compared with experimentally observed two dimensional temperature distributions monitored by an IR camera.
