Influence of Cavity Geometry on Heat Transmission in Restored Teeth.

摘要

In the oral cavity thermal changes can be responsible for tooth damage resulting in pulpitis and pain. The relationship between pain and temperature has been investigated 1-6 widely. Thermal analysis of human teeth however has not been reported frequently. In the last few years thermal analysis has been carried out by calculation of the temperature field in a theoretical tooth model by means of a numerical mathematical method, the Finite Element Method (FEM). However, thermal analysis has been restricted to a comparative investigation into changes of the temperature field in human teeth restored in a various way. The aim of the present study is to analyze the temperature field and heat flow as a function of time in three restored teeth, varying in cavity geometry and the presence of a cement base.
