The analytical evaluation of temperature distribution in dentin uder a pulse Er:YAG laser radiation an investigation of pulse nergy and pulse duration on it

In this paper, the temperature distribution in denthin when radiated by a pulse Er:YAG laser has been evaluated. For this reason, we consider dentin expose by a pulse laser and heat is generated. The nonhemogenous time dependent heat conduction equation has been solved analytically and by using the boundary conditions the temperature distributin has been derived. The obtained results then applied for dentin and by using the dentin datas, the temperature distribution has been plotted. The effect of pulse energy and pulse duration on the temperature distribution have been studied and discussed comprehensively
