Differential scanning calorimetric curves have been obtained corresponding to the desorption of hydrogen from palladium and palladium–silver alloys. There was no evidence for the existence of an exotherm, following the endothermic desorption of hydrogen, which has been previously found and attributed to the relaxation of a metastable, expanded hydrogen-free palladium lattice. Heats of desorption have been evaluated from the areas of the endotherms and these are reasonable in the light of values obtained by other techniques. Comparisons of scanning curves for palladized and unpalladized hydrogen-containing silver–palladium alloys demonstrate that solid-state diffusion cannot be the slow step for the former but may be for the latter.

     Long-term clinical observations show that widely used dentures made of metals and their alloys are not indifferent, cause a number of diseases of the oral mucosa, and have social and medical consequences in the form of intolerance to dental prosthesis materials[1,2]. Currently, ceramic materials, plastics, stainless steels, cobalt-chromium, silver-palladium alloys, gold-based alloys, platinum, etc. are used for orthopedic treatment. these alloys include the following metals: iron, chromium, Nickel, titanium, manganese, silicon, molybdenum, cobalt, palladium, zinc, silver, gold, etc. Signs of intolerance may occur when placing dentures and filling materials in the oral cavity. Intolerance to prosthetic materials can be caused by different reasons that have different mechanisms of pathology development. Solving problems with intolerance to dental materials in each patient requires analysis together with a dentist, an immunologist, and an immunological laboratory [1-4].
