Preventing diseases of oral cavity, specifically periodontal diseases, is currently a high-priority issue. Despite the wide selection of individual oral care products and the abundance of information on individual oral care, the prevalence of tooth decay and inflammatory periodontal diseases remains high. Apart from knowledge of individual oral care, of great importance for patients is their capacity to develop strong motivation for full-scale hygienic procedures.

Satisfaction with quality of life and self-attitude in patients operated by «traditional» (conventional surgical methods) and endoscopically assisted methods are considered in the article. Differences in the quality of life in patients, self-attitude to ones appearance are described. 65 patients were surgically operated and examined. Control group – patients operated by «traditional» techniques (35 patients), the average age of patients was 38 ± 11,1 years. The comparison group – patients operated using endoscopically assisted methods (30 patients), the average age of patients was 44 ± 17,7 years. Psychodiagnostic methods: 1. N. E. Vodopyanova`s scale of life quality; 2. The Short Form-36; 3. S.R. Panteleev`s Assessment of self-relationship. Complaints of paresthesia and pain experienced by patients who underwent a “traditional” operation were revealed as a result of the examination. Operated on with an endoscopically assisted method patients did not present any complaints. Differences between the assessment of the life quality and self-relationship in examined groups were found. Operated on with an endoscopically assisted method patients evaluated life quality, satisfaction with their appearance and physical condition higher than patients operated on with a “traditional” method.

The article is devoted to the search for more accurate psycho-diagnostic methods and assessment tools for determining the degree of cognitive deficits in patients with schizophrenic disorders. The concepts of "cognitive deficits" and "cognitive profile", understood as the ratio of intact and damaged components of cognitive processes and their schematic representation are discussed. The authors substantiate the need for a clear gradation of cognitive impairments in schizophrenia, development of universal translation algorithms of traditional qualitative results (meaningful) analysis of violations of cognitive activity in quantitative indicators. The article is based on the results of experimental psychological study. The investigation involved 128 patients: 76 people with Paranoid schizophrenia (F20 according to ICD-10) and 52 persons with Schizotypal disorder (F21 according to ICD-10). To assess the cognitive deficit, both traditional domestic methods and foreign tests, rarely used in the practice of a medical psychologist were conducted. The study analyzed the difference in cognitive tests performance between groups of patients with several types of schizophrenia and with different disease duration (up to 5 years and more). On the basis of quantitative data, a "cognitive profile" was lined for each disease. As a result, different variants of cognitive deficits, depending on the shape and course of the disease have been identified. The structure and dynamics of the cognitive deficits associated with schizophrenia and various forms depending on the different duration of the disease is described in detail. Also cognitive profiles compiled on this basis.

Currently, translation into clinical practice of scientific knowledge on pathological reorganization of brain mechanisms in psychiatric disorders, as suggested by functional neuroimaging data, remains limited. This situation calls for the exploration of new approaches, which were recently proposed for the combined use of the simultaneous application of psychodiagnostic testing and fMRI scanning. Consequently, a self‐rated psychodiagnostic scale was used as an experimental task during fMRI scanning for patients with major depressive disorder. Given the promising neuroimaging results obtained in these studies, in current research, our objective was to replicate these results and conduct an fMRI study using statements from the von Zerssen depression as experimental conditions. Eighteen patients with recurrent depressive disorder and healthy volunteers participated in the study to replicate the group size of previous research. The results obtained showed that patients with recurrent depressive disorder exhibited greater activity in the right precuneus and bilateral supramarginal gyrus than healthy controls while responding to diagnostically specific (DS) statements compared to diagnostically neutral (DN) ones. These findings replicate the main results of the original study and emphasize the potential of this approach in the field of translational psychiatry. In addition, they contribute to understanding the pathophysiological mechanisms of depression through the use of this unique fMRI paradigm.

This study assessed suicidal risk in patients suffering from non-psychotic depressive disorders within various clinical and nosological forms (F31–F34 mood disorders and F60.31—emotionally unstable personality disorder). Clinical and psychological features were presented, as well as predictors of suicidal risk in patients of these groups. We performed a comparative analysis of the anxiety and depression level, the level of mental pain, fear of death and the severity of anti-suicidal motives in patients with affective disorders and borderline personality disorder (BPD). Based on the results, 100% of patients in these clinical nosological groups were found to have a high level of suicidal risk. Patients with affective disorders have weak anti-suicidal motives and are not fully aware of the consequences of their own death. Patients with BPD have a higher suicidal risk than patients with affective disorders; they are characterized by less pronounced social orientation, demonstrativeness, self-centeredness, less pronounced levels of anxiety and fear of death.

The article deals with the peculiarities of perception (visual gnosis) and thinking in patients with schizotypal disorder. A cognitive pattern of perception, characteristics of voluntary attention and changes in the mental domain in patients with this pathology were described. 45 people suffering from schizotypal disorder (F21 for ICD-10) were examined, including 27 men and 18 women, the average age was 22.06 ± 1.31 years. Control group was the group of university students (30 people) 14 of them men and 16 women, the average age was 21.03 ± 0.9 years, controlshad not suffered from any mental and chronic physical illnesses. Following patho- and neuropsychological techniques were used: figures of Poppelreuter, method «Non-completed images»; «Elimination of excess», Guildford’s test «Social intelligence», Subtest No. 2 of «Group expression», TMT (Trail Making Test, parts A and B). The results have revealed that the visual perception of the patients with schizotypal disorder is disturbed at every stage of visual gnosis, disturbances appear evidently at the stages of formation of a complex image and its further correlation with pattern samples from memory. It has been shown that in patients with schizotypal disorder, the process of internal logical connection between statements is disrupted, as a result, the act of perceptual nomination changes.
