Abstract: Concerns a process to execute thermal cycling tests on odontological materials in a specific equipment, with the basic goal of accelerating the decay of the interface between different materials, and the intrinsic decay of the test object itself, and of simulating oral conditions, keeping the test object fixed in the interior of a test chamber, isolated from the external environment, and the internal environment being adjusted to the desired temperature by way of liquids in diverse temperatures, contained in vats.
