The adhesiveness and impermeability of dental temporary cements are investigated: Eugenol-free TempoCem NE (DMG), Eugenol Repin (SofaDental), and Cinnamic Water Dentin (VladMiVa). With the help of these materials, individual steel caps are fixed on the biological preparations of the teeth. To simulate the chewing load and other characteristics of the oral cavity, an imitation complex is used. A crank mechanism set in motion a gypsum block with teeth fixed on C-silicone with individual steel caps. As a registration of leakage and penetration, the experiment is carried out in an aqueous solution of methylene blue, and walnut kernels are used as a chewing substrate. For two weeks, the teeth with steel caps were subjected to cyclic loads, repeating morning, lunch, and evening meals, as well as cold and hot meals. Adhesion, tightness, and penetration of cements are investigated on parallel saws under magnification.
