What is it about?
Study of how the heat speed in the samples is affected by the age factor.

Why is it important?
Considering the importance of Biological Studies of human parts including teeth, through the Open Photoacoustic Cell technique, the value for the effective thermal diffusivity of the human tooth hard tissues as age function was measured. We believe that the values found here can be very worthy when tabulated and may be not only used for any drugs delivery studies that need to take into account the heat propagation but also to know or calculate the depth profiling of therapeutical substances applied to dental tissues.
Perspectives
The variation in results depending on the age groups show that you should not use samples from different people as single sample measurement as well as average values of the thermophysical properties of human tooth samples. In dental procedures should be checked the close relationship between the amount of heat used and preserving tooth structure.
