ESTIMATION OF THE QUALITY OF COMPOSITE RESTORATION DEPENDING ON THE ABRASIVITY OF POLISHING PASTS

Introduction. Psychological comfort is one of the most important components in the formation of a healthy, full-fledged personality. The requirements of patients to the dentist are not only not limited to the treatment of the underlying disease and the successful restoration of lost functions, but also include the achievement of a good aesthetic effect — patients highly appreciate a beautiful, relief and at the same time smooth restoration. Thus, the relevance of dental restoration is acquiring not only medical significance, but also social connotation. The aim of the work was to carry out a comparative assessment of the quality of the composite restoration using polishing pastes of various abrasiveness. Material and methods. The study involved 60 patients of both sexes, aged 18-43 years, who underwent aesthetic restoration in the area of the anterior group of teeth of 4 and 5 classes according to Black's classification using the light-curing composite material Enamel plus HRi UD5. The observation was carried out in the immediate and long-term periods (12 months after the end of treatment). For finishing the restorations, we used Cleanic, Flairesse, Clean Polish and Enamel Shinec polishing pastes with different RDA indices. The patients were divided into 4 groups depending on the polishing paste used. Results and its discussion. As a result of the study, it was revealed that the RDA index of polishing pastes plays an important role in finishing, exerting great importance on the smoothness of the restoration, "dry shine" and allows to achieve better marginal adaptation of the material and better color fastness of the restoration. Conclusions. Thus, our study revealed the best result in the paste with the maximum value of RDA (83) — Flaresse (DMG).
