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.

In the clinical practice of a dentist-orthopedist, patients with various diseases, abnormalities and deformities are often found. In this case, there may often be a relationship between General somatic pathology and manifestations in the oral cavity. Parkinson's disease is no exception. This paper discusses the main features of the course of the disease in the oral cavity and the principles of a differentiated approach to orthopedic treatment. So in patients with Parkinson's disease, sialorrhea (salivation, hypersalivation), dryness of the red border of the lips and oral mucosa, speech changes, «prosthetic» stomatitis are observed. At the same time, these patients have sensory and vegetative disorders, violation of muscle tone, which aggravates the process of prosthetics and creates certain difficulties for a dentist-orthopedist. Due to the spread of this disease among the elderly, who often require dental care, clinicians need to know about this pathology.

Currently, one of the most common types of prosthetics are restorative crowns or bridges, which cannot provide high-quality retention and long-term fixation with a low crown of supporting teeth. For an orthopedic dentist, the question arises of choosing a method of preparation before prosthetics. In this work, a comprehensive examination and treatment of 95 patients with a low crown of supporting teeth was carried out, who were randomized into 3 groups according to the methods of preparation for orthopedic treatment gingivoretraction, gingivectomy and gingiviplasty. The change in the state of the dentoalveolar complex was carried out clinically and functionally. The hygienic index API, papillary bleeding index PBI, the index of need for periodontal treatment CPITN, gum recession and depth of probing were determined. Laser Doppler flowmetry was used to assess the state of local blood flow and vasomotor activity of vessels. The studied parameters were evaluated before the start of preparation for orthopedic treatment and after 14 days. During the study, complications and side effects were not revealed, however, clinical and functional indicators indicate that preference should be given to gingivoplasty as one of the qualitative methods of preparing the dentoalveolar complex in patients with a low crown of supporting teeth.
