Detailing the effect of cermet structures on the morphofunctional state of periodontal tissues allows us to characterize the features of the preparation of teeth for this type of structure, and as a result of the effect of the structure on surrounding tissues. The aim of the study. Study of reactive changes in gingival epithelial cells of patients prosthetized with ceramicmetal crowns in the dynamics of clinical observations 1 year after odontopreparation and their fixation. Object and research methods. Causal relationships between odontopreparation devital teeth with the formation of a rounded beveled ledge at the level of the gingival margin and the course of differentiation of the cellular composition of the gums after 1 year of clinical observations that arise as a result of orthopedic treatment with full ceramic-metal crowns. Results. After 1 year of clinical observations, 8 out of 10 patients had no complaints. During a clinical examination, of course, in the field of orthopedic constructions were dense, pale pink, they tightly covered the neck of the teeth covered with orthopedic constructions. There are no periodontal pockets. Preferably, a small number of dental layers were visualized in the patellar region. In 2 out of 10 patients, the presence of cyanosis and congestive hyperemia was observed and gingival pockets formed due to edema with signs of congestive hyperemia only in the area of the interdental gingival papillae were diagnosed and chronic catarrhal gingivitis was diagnosed. Conclusions. When analyzing the cellular composition of the gums, it should be noted that the keratinization of the epithelium is enhanced towards hyperkeratosis, which begins in stages with basophilic and eosinophilic surface epithelial cells, with the appearance in the last eosinophilic granules and the subsequent formation of horny scales. The appearance of cells with signs of dystrophic changes can be interpreted as a consequence of the inflammatory process in the gums
