There are many challenges for the physical properties of the ideal dental restorative material. Over the last three decades, it has been frequently reported that the properties of dental restorative composites cured with argon laser are similar or superior to those achieved with conventional halogen and light emitting diode (LED) curing units. At the molecular level, the structural arrangement and movements of atoms are affected as a function of temperature variations. Studies on calorimetric properties and observation of dental gypsums by scanning electron microscope]. Thermal Conductivity (K) -the quantity of heat in calories, or joules, per second passing through a body 1 cm thick with a cross section of 1 cm^2 when the temperature difference of 1 degree C-energy transfer. Therefore, thermal diffusivity, specific heat capacity, and thermal conductivity were measured.
