Abstract

The temperature distribution in dentin under pulse Er:YAG laser radiation has been studied and simulated, analytically. For this reason we considered heat deposited in dentin due to laser radiation. The heat conduction equation has been solved and the temperature distribution has been obtained. The obtained results then have been used for dentin and discussed. Based on the simulation, the temperature rise to 40.5 K for 300 mJ and 21 pulses which have very good consistency with the experiment.
