Current issue
Relevance. Currently, an increasing number of people with complete adentia resort to prosthetics using dental implants. There are techniques for restoring the entire dentition with conditionally removable dentures supported by implants. These technologies make it possible to restore chewing efficiency to 100%, which distinguishes them from removable dentures. At the same time, the integration of dental implants is a lengthy process. This means that during their integration, the patient needs temporary prostheses to maintain an acceptable standard of living. Removable immediate dentures are most often used as temporary prostheses, which are manufactured and applied immediately after the implantation operation. Removable immediate dentures, in their essence, are complete removable plate prostheses and, as a result, require time to adapt to them.
Goal. The aim of the study was to study the effect of the oral hygiene product «Prosthetics fixing cream Protefix Premium 7 (Protefix®)» in patients after upper jaw implantation surgery at the adaptive stage of wearing a removable immediate prosthesis.
Materials and methods. The study involved 60 male and female patients with complete maxillary adentia in the adaptation period to removable immediate dentures. The patients were divided into two equal groups. Patients in group 1 used «Prosthetics fixing cream Protefix Premium 7 (Protefix®)» during the period of adaptation to the prosthesis. Group 2 patients received only standard therapy. All patients were interviewed using the OHIP-14 RU questionnaire, before the study and at the stages of adaptation. The occurrence of adverse events, such as injury to the mucous membrane of the prosthetic bed, was also assessed.
Results and discussion. According to the results of the study, it was found that the use of the investigated oral remedy «Prosthetics fixing cream Protefix Premium 7 (Protefix®)» in patients after surgery for complete prosthetics of the upper jaw on implants at the adaptive stage of wearing a removable immediate prosthesis leads to a significant improvement in the quality of life, as indicated by the results of the survey on 1, 14 and 30 days after the prosthesis was applied. Specifically, in group 1, the average value of OHIP14 decreased from 59 points on the first day to 39 points on the 14th day, and by day 30, the average value was 22 points, which corresponds to a good level of quality of life. In group 2, the dynamics of the decrease in scores was less pronounced, namely, on the first day, the values of OHIP-14 were 59 points, on the 14th day 47 points, and on the 30th day 30 points, which corresponds to a satisfactory level of quality of life. Also, during the research work, it was confirmed that the use of the studied agent leads to a significant reduction or absence of damage to the oral mucosa in the area of the prosthesis during the adaptation period of its use.
Conclusions. Thus, the use of a fixing cream does not exclude the occurrence of undesirable phenomena, such as hyperemia and trauma to the oral mucosa, but significantly reduces the likelihood of their occurrence. In addition, the use of the investigated oral remedy «Prosthetics fixing cream Protefix Premium 7 (Protefix®)» significantly reduces the psychological discomfort of patients during the period of adaptation to a removable prosthesis, which improves the quality of life of this group of patients and may reduce the likelihood of not using a removable prosthesis.
Background. Periodontal diseases, including chronic gingivitis (ICD-10 code K05.1), are widespread among children and adolescents, especially among patients with palliative status. In this category of patients, oral hygiene is often unsatisfactory due to limited physical abilities and insufficient awareness of parents and medical staff. This leads to a decrease in the quality of life of young patients and the development of oral complications.
Materials and methods. The study included 56 adolescents aged 9 to 16 years diagnosed with chronic gingivitis (K05.1) and concomitant somatic diseases. The children were randomly divided into two groups. Patients in the first group were provided with an individualized oral hygiene program using Splat products, while the second group received standard oral hygiene tools. The effectiveness was evaluated based on the dynamics of OHI-S, PMA, PBI indices and the Rosenberg scale for halitosis intensity. Additionally, microbiological analysis of oral mucosa smears was performed.
Results. Incorporation of Splat oral care products (bioactive children’s toothpaste, Splat Junior Magic Foam mousse, and Splat Smilex Ortho+ single-tufted brush) into individual oral hygiene routines during comprehensive treatment of chronic gingivitis demonstrated high efficacy, confirmed by objective data and index-based evaluation. Microbiological analysis at baseline revealed a predominance of potentially pathogenic microorganisms (S. viridans, S. aureus, C. albicans), followed by improvement in the oral microbiome composition after comprehensive therapy. Clinical improvements were observed in both groups, indicating effective hygiene care regardless of product type. However, differences between the groups were not statistically significant.
Conclusion. Splat oral care products (bioactive children’s toothpaste with calcium hydroxyapatite and Luctatol system, Splat Junior Magic Foam mousse, and Splat Smilex Ortho+ single-tufted brush) can be recommended for widespread use in individual oral hygiene as part of comprehensive treatment of chronic gingivitis in children with palliative status, with prior education and hygiene monitoring.
Epidemiological data suggest that, despite improvements in oral health in recent decades, tooth loss is still a common occurrence in elderly patients. Complete rehabilitation with removable dentures remains one of the most popular and traditional prosthetics methods for patients with adentia who have systemic, anatomical, or financial limitations. The healing process of the oral mucosa is an extremely important factor in adapting to new prostheses and significantly affects the quality of life of patients using these dentures. The aim of the study was to assess the oral mucosa of the denture-bearing area in patients with removable complete dentures during the period of adaptation when using adhesive cream or cushions. The study involved 60 patients with removable complete dentures, who were divided into three groups depending on the adhesive agents used during the period of adaptation to the removable prosthesis. The patients of the first group used an adhesive cream, the second – adhesive cushions. Patients of the third group did not use any adhesive agents. On the 14th and 33rd days after the removable prosthesis was applied, a cytological examination of the oral mucosa of the denture-bearing area was performed. The results obtained indicate that the use of adhesive creams and cushions helps to reduce the inflammatory of the oral mucosa, which leads to a reduction in the time required for patients to adapt to removable dentures.
The purpose of the study: to explore the possibilities of using nanomolecular agents of a new class based on graphite hydrosulfate in dentistry and cosmetology practice.
Materials and methods: groups of patients with dyskeratosis and benign neoplasms of the oral cavity, face. Evaluation of the effectiveness of the use in dentistry and cosmetology of a nanomolecular agent based on graphite hydrosulfate (graphite sulfate complex) serum «Liquid Carbon», which has colloidal-dermotropic and antitumor effects, selectively acting on the tissue structure of the skin, mucous membranes and other organs. The developed remedy involves the elimination of the pathological process and the regeneration of the colloidal system, regardless of the type of clinical pathology. Carbon and graphite nanostructures are used in combination with sulfuric acid anions. The sizes of clusters of drug molecules range from 10–20 nm. The agent penetrates the microcirculatory bed of the neoplasm and causes tissue dehydration, mummification of the neoplasm and microcirculatory bed occurs, a natural inflammatory-immune reaction occurs, rejection of the mummified neoplasm occurs, and regeneration of the mucous membrane and skin.
Results: five years of experience in the use of a new class of nanomolecular agent based on graphite hydrosulfate (graphite sulfate complex), Liquid Carbon serum, in patients with dyskeratosis and benign neoplasms of the oral cavity and face. It showed high efficacy in two groups of patients. Of particular interest are dyskeratoses and benign neoplasms in the oral cavity. Methods of application of «Liquid Carbon» in the conditions of dental reception have been developed. First of all, there was no recurrence after the treatment and a high cosmetic effect on the skin of the face. On the oral mucosa, neoplasms and dyskeratoses usually disappear almost completely with minimal scarring.
Conclusion: based on the study of the literature devoted to research on the treatment of skin neoplasms and the practical experience we have gained in using the «Liquid Carbon» serum (graphite sulfate complex), primarily in dental practice in the treatment of dyskeratosis and benign neoplasms of the oral mucosa, the high effectiveness of the proposed method has been revealed. At the same time, it is necessary to develop practical recommendations for the use of the above-mentioned remedy in dentistry, taking into account, first of all, cancer awareness and effective interdisciplinary collaboration with dermatologists and oncologists.
Relevance. The success of orthodontic correction on fixed devices largely depends on the stability of each element on the enamel surface during the entire course of treatment. Braces should not interfere with oral hygiene of patients undergoing orthodontic treatment, and should withstand occlusive loads, chewing, and traction forces generated by the arch. In addition, the braces should be removed after treatment without damaging the enamel. Variables such as the type of polymerization, the adhesives used, and the methods of preparing the enamel before fixation affect the adhesive strength of the bracket. Modern scientific research is being conducted in the direction of improving the adhesion properties of bonds and is an urgent task. Treatment with sodium hypochlorite helps to remove demineralized collagen from the tooth surface. In turn, the role of phosphoric acid is to enhance the shear strength when fixing braces. This article evaluates the shear strength of an adhesive system with pretreatment with sodium hypochlorite and orthophosphoric acid in laboratory conditions.
Aims: to study the shear strength of a universal adhesive system in the laboratory when fixing braces with various methods of enamel surface preparation.
Materials and methods. The samples of teeth removed according to orthodontic indications n=60 (100%), without carious lesions and large fillings, were prepared for the study. Each tooth was placed in a block with self-hardening plastic or plaster. The samples were divided into three groups of n=20 samples. Before applying the adhesive system, the surfaces of n=20 (33.3%) samples were treated with 37% phosphoric acid, n=20 (33.3%) other samples were treated with 3.25% sodium hypochlorite, n=20 (33.3%) samples were without pretreatment. Then metal braces were fixed on the prepared samples. Each of the groups was divided into 2 subgroups – n=10 samples with thermal cycling and n=10 samples without thermal cycling. Two-component self-curing adhesive system Universal Bond II (Tokuyama Dental); adhesive fixing cement ESTECEM II PLUS (Tokuyama Dental), 37% orthophosphoric acid and 3.25% sodium hypochlorite were used to fix the braces.
Results: there was a statistically significant difference between the groups with 37% phosphoric acid and 3.25% sodium hypochlorite pretreatment and the group without pretreatment, both before and after thermal cycling. The highest shear strength values before thermal cycling were obtained in the group with phosphoric acid pretreatment (10.12±1.27 MPa). The weakest shear strength (4.10±0.96 MPa) was found in samples without pretreatment of the enamel. After thermal cycling, the results of adhesive strength significantly decreased.
Conclusions. The use of 37% orthophosphoric acid and 3.25% sodium hypochlorite can increase the adhesion strength of braces to enamel by more than two times. Thermal cycling reduces shear strength in all groups. However, the available studies are insufficient to assess the role of 37% phosphoric acid and 3.25% sodium hypochlorite in shear strength, and therefore further research is needed in this area.
Relevance. Modern rehabilitation methods offer a variety of treatment options, one of which is immediate dental implantation. However, several factors may limit the applicability of this approach. An alternative rehabilitation method is the autotransplantation of third molars.
Objective. To perform a comparative analysis of third molar autotransplantation and immediate dental implantation based on objective and subjective parameters.
Materials and methods. The study was conducted at the Department of Oral Surgery, E.V. Borovsky Institute of Dentistry, Sechenov University. A total of 30 patients (15 males and 15 females) aged 18 to 52 years were enrolled. Depending on the treatment method, patients were divided into two groups: in Group 1, patients underwent tooth extraction followed by third molar autotransplantation; in Group 2, patients underwent tooth extraction with immediate dental implantation. Postoperative evaluation included tooth mobility after autotransplantation and mobility of the contralateral tooth at 3 and 6 months; implant stability intraoperatively and at 3 and 6 months postoperatively; subjective data based on quality of life assessment (OHIP-14), pain intensity using a visual analogue scale (VAS), and the severity of soft tissue swelling.
Results. Six months after autotransplantation, the mobility of the transplanted teeth (1.7±3.7 units) did not differ significantly from that of the contralateral teeth (-0.2±2.9 units) (p=0.058). Implants demonstrated statistically significant differences at each evaluation stage (p<0.001). In the early postoperative period, pain was significantly higher in the autotransplantation group (p<0.001), but no significant differences were observed during subsequent follow-up. Quality of life scores and swelling did not differ significantly between the groups.
Conclusion. Six months after the procedure, tooth mobility following autotransplantation was comparable to that of natural teeth. Postoperative discomfort and quality of life outcomes were similar in both groups.
Aim of the study. To develop a system for assessing the risk of bleeding in patients with comorbid cardiovascular pathology requiring anticoagulants and/or blood antiplatelet agents in preparation for dental implantation.
Material and methods. The study included 135 elderly patients of both sexes with cardiovascular pathology in preparation for dental implantation. Prothrombin time, International Normalized Ratio (INR), and thrombocrit were determined in venous and gingival blood.
Results. In patients of the clinical group, the prothrombin time and INR values for platelet-poor plasma and gingival blood did not differ (p>0.05). Since platelet-poor plasma and capillary blood differ in the percentage of platelets, it is advisable to introduce an appropriate correction factor when using gingival blood to control hemostasis. To calculate the correction factor (КРst) for thrombocrit (PCT), the following formula was developed using the regression analysis method: КРst = -0.06×PCT + 1.2. The INR value in gingival blood was multiplied by the correction factor КРst. In patients with hemorrhagic complications, in contrast to patients with an uncomplicated postoperative period, the INR value in gingival capillary blood adjusted for thrombocrit was higher (p=0.021), and the thrombocrit in the blood was lower (p=0.038). If the INR value in gingival capillary blood adjusted for thrombocrit is higher than 1.29, then the risk of bleeding during dental implantation is high (diagnostic sensitivity 81.25%, specificity 84.9%).
Conclusion. A high risk of bleeding during preparation of elderly patients with cardiovascular pathology for dental implantation is a rationale for discontinuing anticoagulants and/or antiplatelet agents during preparation and dental treatment.
Introduction. Implantology is currently one of the most dynamically developing areas of dentistry, which is due to the growing prevalence of partial and complete absence of teeth, as well as the increased need of patients for highly effective methods aimed at restoring chewing function. The key factor for successful implantation is osseointegration, the process of forming a strong bond between bone tissue and a dental implant. Effective osseointegration ensures not only the reliability and long-term functionality of the implants, but also the stability of the entire structure. Existing studies on the effect of micro- and macrorelief of the implant surface on the process of osseointegration provide contradictory data. The purpose of this literature review is to evaluate the effect of various types of dental implant surfaces on the speed and quality of osseointegration, as well as on the durability of implants.
Methods. For the research, a detailed search of scientific data was conducted in the electronic databases PubMed, Cyber Leninka, Elibrary, Google Scholar. The search was limited to articles in Russian and English using the terms «osseointegration» and «micro- and macro-relief of implants».
Results. The study showed that the correct choice of surface characteristics, depending on the patient’s anatomical features and operating conditions, can significantly increase the likelihood of a successful treatment outcome and ensure long-term functionality of dental implantation.
Conclusion. The results obtained emphasize the importance of osseointegration for the stability, viability and effectiveness of dental implantation, which directly depends on its micro- and macrorelief surface.
Transversal maxillary anomalies affect a significant number of patients, accounting for 23.3% of those seeking orthodontic treatment. The narrowing of the upper jaw occurs during the growth and development of the facial skeleton, and one of the most common causes is myofunctional disorders, such as bad habits like thumb sucking, mouth breathing, and incorrect tongue position. Osteotomy in the area of the pterygoid processes of the sphenoid bone and its impact on the outcome of treatment has not been fully studied and discussed. Given the increased risk of complications associated with osteotomy in this area, such as damage to the pterygoid venous plexus, prolonged surgery time, and additional incisions, this procedure should only be performed when indicated and according to a standardized methodology.
Material and methods. In this study, we conducted a literature review of scientific publications on this topic using the Scopus bibliographic and abstract database from 2010 to 2024. We used the search terms SARME, SARPE, RME, and Surgically assisted maxillary expansion to search for relevant articles in the Title – Abstract – Keywords mode. A total of 2,155 articles were identified in the Scopus database as of 2024. After reviewing the headings, annotations, and removing duplicates, the full texts of 25 articles were read. These articles were analyzed based on the criteria for inclusion, non-inclusion, and exclusion, and seven studies were included in this systematic review. A total of 291 participants were included in the study, and the sample mainly consisted of young female patients.
Conclusion. Based on the results of this study, there were no significant differences in upper jaw expansion between the patient groups. In the conclusion, the authors of the scientific papers noted that surgical upper jaw expansion is an effective treatment for patients with transverse jaw anomalies. The result of the assessment in all studies was a difference in the size of the upper jaw, as measured by plaster models of the dentition. However, this method of assessment raises doubts about the statistical reliability of the study. Therefore, it is recommended that a scientific paper be written evaluating the quality of surgical maxillary expansion in two groups of patients in the future
Currently, in prosthetics using dental implantation, increasing the thickness of the gums by using connective tissue autografts, which are formed from the mucous membrane of the palate or from the tubercle of the patient’s upper jaw, is widely used. The main disadvantage of using connective tissue autografts is the presence of an additional second surgical field. In this regard, the problem of finding connective tissue grafts that replace autografts to increase the thickness of the gums is relevant. This article describes the experience of using a resorbable two-layer membrane designed for guided bone regeneration to increase gingival thickness in the area of a xenograft dental implant.
Mesial occlusion is a common anomaly that affects facial aesthetics, which can subsequently affect the patient’s psycho-emotional health. Proper diagnosis and treatment plan planning will help to achieve more predictable results. The article presents the analysis of reliability of differences between growth types in patients with gnathic form of mesial occlusion.
The study is devoted to the complex therapy of chronic herpetic gingivostomatitis, the purpose of which was to increase the effectiveness of treatment of the disease in patients undergoing orthodontic treatment with aligners. It presents data on treatment methods, results of immunological control and conclusions on the effectiveness of therapy in 112 patients undergoing long-term orthodontic treatment with aligners. Patients were divided into two groups: the main group (59 people) and the control group (53 people). The main group, in addition to etiotropic treatment, received physiotherapy. Immunomodulatory therapy in the main group included the drug Meglumine acridonacetate, and in the control group, the drug Imudon. During immunological control, the activity of lysozyme and the level of secretory immunoglobulin A in saliva, as well as the level of IgG antibodies to the herpes simplex virus were measured. After processing the laboratory data, it was concluded that the main group showed more pronounced improvements compared to the control group in both lysozyme activity and s-IgA levels, and the level of IgG antibodies to the herpes simplex virus significantly decreased in the main group 2 months and 6 months after treatment compared to the control group. Treatment in the main group was more effective: it contributed to faster healing and a decrease in the level of antibodies to the virus. The results emphasize the importance of using a comprehensive approach to the treatment of herpes infection and monitoring the immune response.
The ratio of biopotentials of the studied muscles as a result of combined treatment of adult patients with gnatic forms of malocclusion during double-jaw surgery is formed due to balanced changes in the amplitude of EMG and the period of bioelectric activity of the temporal and masticatory muscles, as well as a decrease in the amplitude index and an increase in the period of bioelectric rest of the supra-lingual muscles. General practitioners in their practice paid attention to the kinesiotaping method, the mechanism of action of which is based on the creation of favorable conditions for the normalization of microcirculation in the connective tissue of the skin, reducing pain and optimizing afferent pulsation at the segmental level.
Materials and methods. We examined 40 orthodontic patients before and after orthognathic surgery, who were divided into two equal groups: group 1 – without kinesiotaping; group 2 – with kinesiotaping. Patients underwent electromyographic and kinesiographic examinations to assess the effects of kinesiotapes during rehabilitation.
Results and discussion. The usage of kinesiotapes after orthognathic surgery has a beneficial effect on faster recovery of patients.
Relevance. The comparative effectiveness of antimicrobial therapy and light pyre therapy in the treatment of chronic generalized periodontitis has not been sufficiently studied. Further development and implementation of methods for the treatment of periodontal diseases with minimal drug load is necessary.
Objective. To compare the effectiveness of antimicrobial and pyler-therapy in the treatment of mild chronic generalized periodontitis.
Materials and methods. The treatment was carried out in two groups of patients (40 people each), aged from 30 to 50 years (44 women and 36 men). In the first group, Dentameth gel containing metronidazole and chlorhexidine bigluconate was used. In the second group, piper therapy was performed using the Bioptron Pro-1 device. The hygiene index and periodontal index were calculated, and the activity of neutrophilic leukocytes was determined before therapy, one, three, and six months after treatment.
Results. Antimicrobial therapy and pyler therapy have a significant positive effect on the periodontal condition of patients for three months (p<0.05). The values of the periodontal indices obtained after six months allow us to consider the treatment performed insufficient. The activity of myeloperoxidase and the number of cationic proteins intracellularly in neutrophilic leukocytes increases during the month, and decreases by three and six months, which is directly correlated with the clinical symptoms.
Conclusions. In the treatment of chronic generalized periodontitis, antimicrobial therapy and pyler-therapy show the same high efficacy, which persists for three months. When using only one of these methods as the basic active periodontal treatment, supportive periodontal therapy is indicated after three months.
Background. The study of microhardness of dental materials, especially those used in pediatric dentistry, is an important task in modern dentistry. Glass ionomer cements (GICs) and E-max MT ceramics are widely used for tooth restoration, but their mechanical properties compared to primary tooth enamel remain understudied.
Objective. To evaluate the microhardness of glass ionomer cements (Fuji-9, Vitremer) and E-max MT ceramics in comparison with primary tooth enamel.
Materials and methods. Laboratory tests were performed on 25 samples of each material.
Microhardness was measured using a manual digital press RPG-75. Statistical analysis included Shapiro – Wilk, Levene, Bartlett, Kruskal-Wallis, and Dunn tests (p < 0.05).
Results. Primary tooth enamel exhibited microhardness of 1.97 ± 0.22 kN, surpassing GICs (Fuji-9: 1.11 ± 0.15 kN; Vitremer: 1.36 ± 0.07 kN) but remaining inferior to E-max MT ceramics (8.03 ± 0.71 kN). Intergroup differences were statistically significant (p < 0.05).
Conclusion. E-max MT ceramics show the highest strength, making them suitable for load-bearing restorations. GICs, while less durable than natural enamel, offer advantages in biocompatibility and anti-caries effects, which are critical in pediatric dentistry.
Oral mucosal diseases pose a significant diagnostic challenge due to the similarity of clinical presentations across different pathologies. The integration of Clinical Decision Support Systems (CDSS) represents a promising approach in dentistry to improve diagnostic accuracy.
Objective. This study aimed to evaluate the effectiveness of diagnosing oral mucosal diseases with and without the use of a CDSS.
Materials and Methods. The study utilized:UMKB (United Medical Knowledge Base) – a unified medical knowledge base, CDSS (Clinical Decision Support System) and an electronic physician assistant,patients and expert dentists. A comparative prospective study was conducted involving 102 patients with oral mucosal diseases. Diagnostic accuracy was assessed with and without CDSS assistance. Patient satisfaction with the diagnostic process was evaluated via digital questionnaires (Google Forms).
Results. The use of CDSS by dentists: increased the frequency of preliminary diagnoses (92% with CDSS vs. 78.8% without),iImproved diagnostic correctness (86.5% with CDSS vs. 51.9% without), enhanced final diagnosis completeness (90% with CDSS), increased preventive care recommendations (94% with CDSS vs. 73% without).
Conclusions. The CDSS significantly improved: diagnostic accuracy (p = 0.002), data completeness (p < 0.001 for general and oral mucosal examinations), reduced the need for external consultations (p = 0.003), expanded preventive care coverage (p = 0.004). Patient satisfaction was higher with CDSS use (p = 0.003), though this correlation weakened with age (p = 0.047).
Photodynamic therapy is a rapidly developing non-invasive treatment method that holds significant promise in dental practice. This review article discusses the principles of action of photodynamic therapy, as well as the possibilities of its application in the prevention of dental diseases such as caries, periodontitis, peri-implantitis and oral tumors. The unique advantages of photodynamic therapy, such as selectivity of action, a broad spectrum of antimicrobial effects, the absence of resistance development and its synergistic effect with other treatment methods, are emphasized. However, challenges such as delivery of the photosensitizer, the penetration of light into deeper tissues, oxygen availability and the need for standardization of protocols are also recognized. The integration of advanced technologies such as nanotechnology and synthetic biology into photodynamic therapy may provide a solution to some of the current limitations of the method and further improve the effectiveness of photodynamic therapy in the prevention of dental diseases.
Relevance. The study of hormonal markers of stress, particularly salivary cortisol levels as an objective indicator of patients’ psychoemotional state, is of particular importance. Cortisol is an important biomarker reflecting the body’s response to stress and emotional tension, making it a promising research object in the context of studying patients’ unjustified complaints about the quality of aesthetic dental treatment.
The aim of the study was to investigate the personality type and salivary cortisol levels in patients with unjustified complaints about aesthetic dental treatment outcomes.
Materials and methods. The study involved 42 patients of both sexes aged 21 to 50 years who underwent aesthetic restorations of the anterior teeth group between 2019 and 2023. Exclusion criteria included patients under 18 and over 50 years of age; patients with high caries intensity and poor oral hygiene, as well as those requiring periodontal disease treatment; patients who violated the study protocol or refused further participation. Exclusion criteria also included patients with general somatic pathology in the decompensation stage; acute pain; patients with severe personality changes due to organic CNS lesions; gross mental and behavioral disorders; pregnant women. The control group consisted of 10 patients aged 21 to 40 years (5 men and 5 women) who had previously undergone aesthetic dental treatment, without significant somatic pathology (according to history), with low anxiety levels, and balanced personality traits according to psychological testing. Psychological testing was conducted using the scales of personal (PT) and reactive (RT) anxiety by C.D. Spielberger in the modification by Yu.L. Khanin, as well as the Mini-Mult Questionnaire (Mini-Mult), Three-Factor Perfectionism Questionnaire, MOCIs Scale of Obsessive-Compulsive Symptoms. Salivary cortisol measurement was performed using high-performance liquid chromatography-mass spectrometry (HPLC-MS) in 4 stages at the following time intervals: 1st portion (6:00–10:00); 2nd portion (10:00–14:00); 3rd portion (14:00–20:00); 4th portion (20:00–24:00). All patients gave voluntary consent to participate in the studies. Statistical analysis was performed using IBM SPSS Statistics v.20.0, MedCalc v 14.8.1, and software packages written in R.
Conclusions. An analysis of the results of our study showed that the frequency of respondents with a pronounced hypochondriac radical among patients making unfounded complaints about the quality of aesthetic treatment was 24%, with paranoid alertness-17%, with physical perfectionism-38%, with obsessive-compulsive personality traits-21%. It was revealed that the highest concentration of cortisol in saliva was observed in patients with a pronounced hypochondriac radical and a high level of personal anxiety. Significantly lower cortisol levels were found in the group of patients with obsessive-compulsive personality traits, but with higher levels of both personal and situational anxiety.
Objective: to study the dietary habits among student youth and identify the risk group for the development of a cariogenic oral cavity based on nutritional parameters.

Introduction. Military personnel demobilized from military service, having completed their work in the ranks of the Armed Forces of the Russian Federation, return to life in a modern society, which opens up wide opportunities for building a family and a career. Dental diseases, which are widespread among military personnel of various forms of conscription, can become an obstacle to their successful social life. A detailed analysis of domestic literature, which highlights the features of dental orthopedic diseases of military personnel demobilized from military service, as well as the experience of leading specialists in the country in providing them with dental orthopedic care, determined the relevance of this publication.
Objective – to conduct an analysis of the existing domestic literature devoted to the dental orthopedic health of military personnel demobilized from military service, characterizing their need for dental orthopedic treatment.
Methodology. The research method was a theoretical analysis of available sources of domestic literature, which published information on dental orthopedic morbidity among military personnel demobilized from military service and methods for providing them with dental orthopedic care.
Results. The analysis of dental orthopedic morbidity among young and middle-aged men demobilized from military service showed that their need for dental prosthetics is 82.7%. To a large extent, this is repeated dental prosthetics with replacement of existing dentures – 48.1%. A significant part of the structure of dental orthopedic structures is made up of removable dentures for complete and partial loss of teeth (13; 50.3%), as well as protective restorative crowns installed on post and core inlays (61.3 and 38.3%). At the same time, young and middle-aged military personnel who continue to serve in the ranks of the Armed Forces of the Russian Federation more often installed fixed dental prosthetics – bridge prostheses and protective crowns (52.0 and 7.53%, respectively).
Conclusion. The study of the dental health of young and middle-aged military personnel demobilized from military service is necessary for planning the provision of highly qualified dental care to them in a civilian setting for the purpose of their social and medical rehabilitation.
