What is Thermal Conductivity (K)

A numerical investigation of steady state heat transfer phenomenon in human tooth is carried out in this present study. The materials generally used for repairing human tooth are ceramics, gold, structural steel, and copper. These materials are considered for the three-dimensional heat transfer analysis. The shape of the teeth is considered as perfect cubic of dimensions 5mm X 5mm X 1.5mm. The simulation results show that the teeth are subjected to temperatures of varying nature in both X and Y directions whereas Z direction is same. It is found that the temperature is maximum at the top of the teeth and minimum at bottom of the teeth (i.e., root). The contours of the heat transfer analysis for various teeth materials shows that the layers of the teeth are subjected to varying temperature. It is also found that the heat transfer characteristics depend not only on shape and boundary conditions but also on the materials used for the teeth selection.
