| Abstract: | We examine the temperature fields of human enamel Yu D, Fox JL, Hsu J, Lynn Powell G, Higuchi WI. Computer simulation of surface temperature profiles during CO2 laser irradiation of human enamel. Opt Eng 1993; 32(2)] during multi-modes CO2 laser irradiation. For this we use the integral transform method as well as direct and inverse Laplace transform Oane M, Sporea D.

Temperature field modeling in laser heated metals for laser cleaning of surfaces. Proc SPIE 2003; 5227: 323–8]. The enamel block is modeled as homogeneous cylinder in three dimensions. Results indicate that (i) the thermal field depends on multi-modes structure; (ii) heat transfer coefficient plays an important role in temperature distribution. |
