Optical techniques for the evaluation of thermo-functional gradients in human dentine

Human tooth structure in the oral environment is affected by considerable thermal fluctuations while consuming hot and cold, fluids and food materials. This paper describes the use of digital moire interferometric technique and Electronic Speckle Pattern correlation Interferometry (ESPI) to study the behavior of the functionally adapted dentine materials to thermal loads in its own plane and out of plane. Further, this study also highlights the advantage of optical techniques with enhanced sensitivity and spatial resolution to examine the whole-field thermal property gradients in an anisotropic biological material such as human dentine.
