Resumo
The purpose of this study was to analyse surface and pulpal temperature
changes in extracted human teeth subjected to
Er,Cr:YSGG laser irradiation by using Finite Element Method
(FEM) and comparing with thermal analysis made by thermocouple
and thermocamera. Twelve extracted human molar teeth
were selected and divided into three groups, according to the following
Er,Cr:YSGG laser irradiation conditions: 2.8 J/cm2, 5.6
J/cm2 and 8.5 J/cm2. During laser irradiation, surface temperature
was measured using a thermocamera (FLIR Systems - USA)
and the pulpal temperature was monitored by means of a thermocouple
type T placed in the pulpal chamber. For FEM analysis, it
were constructed numerical models that reproduced a typical
sound molar teeth and the analysis simulated the absorption of the
laser energy and the heat transfer through the tooth in three
dimensions, considering the same laser energy and conditions
performed in thermocouple and thermocamera measurements.
The results showed that theoretical FEM calculation showed
good agreement with the thermocamera and thermocouple
obtained data, simulating heat transfer and predicting the temperature
increase. It was possible to conclude that 3D Finite Element
Method gives good results that makes possible to understand the
thermal behavior of dental material.
