It is proved that the chemical and mechanical effects of the prosthesis basis, along with the therapeutic properties, have side effects that are associated with the principal scheme of its design, as well as the violation of self-purification, thermoregulation, and analyzer function of the mucous membrane of the prosthetic bed. The purpose of the work was to determine the structural features of the mucous membrane of the tongue root of rats after the action of 1% of the ether of methacrylic acid. The study used 25 white non-breeding male rats – control group – 5 animals and experimental group – 20 animals, which treated the oral mucosal membrane with a 1% solution of methyl ester of methacrylic acid for 30 days. After euthanasia of animals at 14 and 30 days, fragments of the tongue root mucosa were embided in epon-812. Half-thin sections were painted with a polychrome dye. Morphometric study and microphotography were performed using Biorex-3 VM-500T microscope with digital DCM 900 microprotector with adapted data research programs. Quantitative analysis of the results of morphometric studies and statistical processing of morphometric data was performed with generally accepted statistical methods using the Exel program. The average thickness of the epithelial and its own plates, the diameter of the lumen of the arterioles, the capillaries and the venules was determined, the average quantity in the field of view of the migrant cells of the connective tissue of its own plate. Study of the structural organization of the mucous membrane of the root of the tongue of rats has found that the basic laws of the structure, it is fundamentally different from that of human. It is determined that from the 14th day of action of 1% of ether of methacrylic acid in the epithelial plate, the phenomena of hyperkeratosis and violation of the differentiation of the epithelium in the form of parakeratosis are detected. Up to 30 days of the experiment in the studded layer, vacuolation of the cytoplasm of keratinocytes was detected. The connective tissue of own plate had signs of hyperhydration throughout the period of observation. In the own plate of the mucous membrane of the tongue of the rats on the 14th day of the experiment, the narrowing of the lumens of the resistive and exchange units of the hemomycocirculatory channel, which varied by extension until the 30th day, was determined. From the side of the capacitive links, there was a dilation during the entire observation period. Migrative connective tissue cells are represented by macrophages, lymphocytes, plasma cells and mastocytes in the control group rats. After the action of 1% of ether of methacrylic acid on the 14th day of the experiment, an average increase in the average of 25-30% in the field of view of all examined cells was determined. Restoration of indicators for the 30th day of observation has not been established.
