Relevance. Psychoemotional stress is referred to as a disease of civilizations. When the psychophysiological state of a person is disturbed, all resources are directed to compensating for the pathological situation. With depletion and the development of adaptive capabilities, various disorders of microhemodynamics arise.Materials and methods. In this article, psychoemotional stress is considered as a pathogenic factor in the development of post-prosthetic complications at a dental appointment. Using laser Doppler flowmetry, a comparative analysis of microcirculatory changes in the oral cavity in patients with inflammation of the peri-implant tissue was carried out.Results. Previously, all people had a violation of the psychophysiological state. The control group consisted of healthy people. It is proved that in the comparison group microcirculatory changes occur with the development of arterial hyperemia. In this case, hyperemia was revealed by the ratio of the contribution of pulse and respiratory fluxmotions.Conclusion. Thus, it can be assumed that it is psychoemotional stress that is the primary factor in the development of the inflammatory response in the oral cavity. What should be taken into account at the orthopedic appointment when drawing up a treatment plan for such patients.

The review presents an analysis of articles published for the period 2005-2021. in top-rated publications devoted to the research results in the field of creating light-curing (photopolymerizable) compositions for use in dental practice. The information concerning the main ingredients of the compositions: di (meth) acrylate monomers, fillers, pigments, and photoinitiators is summarized. A comparative assessment of light sources, which determine the curing efficiency of materials of such a functional purpose, is presented. The results of a patent search, in the PatentScope database, are presented. For the period 2000-2021. have been identified 692 patents, which are related to the creation of dental photopolymer composites.
