The main cause of prosthetic stomatitis belongs to the chemical and toxic action of the residual monomer of the prosthesis base, which is a protoplasmic poison. Occurrence of prosthetic stomatitis depends not only on quality of production of prosthesis in laboratory though at non-observance of technology indicators of residual monomer can reach 2-5%, but also at individual intolerance at its minimum concentration in a prosthesis after polymerization - 0,2-0 .5%. The aim of our study was to increase the effectiveness of orthopedic treatment of patients with prosthetic stomatitis by coating the plastic of removable prostheses with nanoscale materials. Materials and methods. To solve this goal, we studied the condition of the tissues of the prosthetic place of patients with prosthetic stomatitis with prosthetic removable prostheses with modified plastic. Orthopedic dental treatment of 50 people was examined and performed, including 25 people (the second group, prostheses were not covered with nanoparticles) and 25 people (the third group, prostheses were covered with nanoparticles). The first control group consisted of 10 people without signs of pathology. Prior to treatment, all patients had removable acrylic plastic dentures. The reason for seeking orthopedic care was a violation of masticatory function and the inability to use previously made prostheses due to the development of pain in the soft tissues of the prosthetic place. Complaints of pain were observed in all patients of varying intensity, impaired fixation and stabilization of the prosthesis due to swelling of the mucous membrane of the soft tissues of the prosthetic place, heartburn and dryness were observed in 90% of patients. Complaints were also about speech and aesthetic defects. Patients of III group after two weeks of using prostheses were coated with the inner surface of the prosthesis, which is in direct contact with the mucous membrane of the prosthetic place with molecules of fullerene C60, by magnetron sputtering. For this purpose, the prostheses were removed from the patients for several days and returned after the coating with the nanomaterial, after which the observation was continued. The results. After coating the prostheses in patients of group III with Fullerene C60, we observed the disappearance of inflammation of the mucous membrane under the prosthesis and patients noted the absence of discomfort. Рatients in II group had a negative dynamics in 80% and had diffuse inflammation of the mucous membrane under the prosthesis. Within 3 months of use, 18 patients (72%) in II group reported that they stopped using removable dentures during the day, due to unpleasant pain under the prosthesis, and used only during meals and during conversations. In contrast to II group, patients in III group did not notice discomfort when using plate prostheses. Conclusions. Obtained in the course of the work convincingly prove the effectiveness of the use of removable plate prostheses with nanocoating for the treatment and prevention of prosthetic stomatitis in patients. This is evidenced by the data of objective examination and the disappearance of complaints from patients.

Periodontal disease is known to be the most common and serious health problem in dogs today. Despite the rather large arsenal of medicinal substances, the problem of treatment and prevention of periodontal disease remains relevant. Based on this, the purpose of the work was to study the features of chronic catarrhal gingivitis and to develop an effective treatment regimen for dentistically ill dogs. For research, two groups of animals with chronic catarrhal gingivitis were formed in 5 dogs in each (control and experimental), selected on the principle of analogues in terms of age, character and localization of the inflammatory process. Animals of the control and experimental groups were performed tartar removal, irrigation of the oral cavity with water and drying of the mucosa with a sterile gauze swab. Dogs of the control group on the mucous membrane was applied 1 ml of septogel 2 times a day, and the experimental – argumentistin 2 times a day. Before and after the procedures on the mucous membrane was applied a 3 % solution of hydrogen peroxide. It was determined the prevalence of dental disease in dogs, the influence of microflora on the condition of the oral cavity of dogs with chronic catarrhal gingivitis, the clinical condition and the main indices and samples were studied, reflecting the intensity of the inflammatory process in the gums of sick dogs and was developed a method of treatment. The results of researches have shown that the use of argumentistin in the complex treatment of dogs with chronic catarrhal gingivitis helps to reduce the recovery period by 5 days.

Aim. To study the influence of dental diseases and results of their treatment on patient’s psychological profile. Methods. 40 patients with hard teeth tissues and dentition defects at the esthetic zone aged from 30 to 57 years were included in the study. Control group consisted of 25 people not requiring dental treatment. A new method of determining patient’s psychological subtype, offered by A. Anuashvili and based on computer analysis of the patient’s photographs, allowing totally avoid the subjectivity of a diagnosis. Results. Analysis of emotional stress level in patients before the dental procedures showed that it was significantly higher in males compared to females (73.6±0.86 vs 57.9±0.93% respectively, р 0,01). It was also found that 60% of all patients had unstable aspects of psychological subtype regardless of gender. In the control group, only minor changes of psychoemotional state between two examinations were registered, allowing to conclude that psychoemotional state without strong stimuli is quite stable. The use of the video-computed psychoanalysis method can help a dentist to assess the patient’s psychoemotional status when patient is seeking for dental aid, and to communicate better considering the patient’s psychological subtype, as well as to control psychoemotional state during and after the treatment. Conclusion. Missing teeth not only impair chewing, but also deteriorate patient’s psychoemotional state, leading to worse quality of life.

Subject. Currently, there are many methods for restoring the crown of the tooth using various stump pin designs, but they are not always effective when prosthetics are removable dentures. Therefore, overlapping prostheses using locking elements and dental implants are becoming increasingly popular in the clinic of orthopedic dentistry. Locking fasteners can reduce pressure on the mucous membrane, increase functional efficiency by transferring pressure to the abutment teeth, which positively affects the stabilization and retention of orthopedic structures. The goal is to improve the quality of orthopedic treatment of partial absence of teeth with the help of overlapping prostheses based on spherical attachments, dental and collapsible dental implants. Methodology. Orthopedic treatment was performed for 27 patients (12 men and 15 women) aged 59 to 74 years, who were divided into two groups: control (10 people) and main (17 people). For patients of the control group, dental treatment was carried out using partial removable laminar prostheses using generally accepted technologies, the main one using advanced technologies for the manufacture of removable dentures and collapsible dental implants. Results. The use of removable orthopedic constructions based on teeth and dental implants using an advanced manufacturing technology (RF Patents No. 2593349, 2708828, 2588488 for an invention) made it possible to carry out dental treatment of patients with partial absence of teeth. An assessment of the quality of hygiene of removable dentures. Conclusions. The effectiveness of prosthetics depends on the rational choice of the orthopedic design and the use of dental implants, as well as the correct assessment of the periodontal condition of the abutment teeth and the determination of contraindications for the manufacture of cast stump pin inlays with spherical locks.

The article presents a scientific overview of the literature on the actual problem restorative dentistry: preparation low-supple atrophied tissue prosthetic bed before the prosthesis patients with complete absence of teeth in the lower jaw. Despite significant progress in prosthetic dentistry, the problem of prosthesis patients with complete absence of teeth on the lower jaw does not lose its relevance. From 15 to 46% of patients aged 45-70 years, need to manufacture complete dentures. One of the factors that directly affect the fixation of complete removable lamellar denture for the lower jaw is a condition of the mucous membrane of prosthetic bed. The most unfavorable for prosthetics full removable laminar dentures is considered as grade 2 mucosa classification Supple. This class is characterized by thinned, stretched and dry mucous membrane of the prosthetic bed. To achieve success in the orthopedic treatment of such patients need to restore the volume and pliability of the mucous membrane of toothless prosthetic bed. A study of the basic methods of surgical, orthopedic, physiotherapy preparation of tissue prosthetic bed toothless lower jaw, and combinations thereof. Of the known methods of noteworthy ways of plastics of the alveolar part of the mandible and increase in volume of soft tissues of the prosthetic bed toothless method Plasmolifting, and the combination of the introduction of autoplasma rich in platelet with the production time immediat dentures with elastic lining. Describes the advantages and disadvantages of the proposed methods. Despite the many different ways of preparation of prosthetic bed before prosthetic treatment, this problem remains unsolved and requires further study.

Abstract α-tocopherol is known to be a powerful antioxidant, in this regard, it was added to bovine oocyte in vitro maturation media to evaluate its effect on oocyte maturation. Oocytes (n = 624) aspirated from ovaries of slaughtered cows were classified by quality and divided in four categories according to cytoplasm appearance and cumulus cells layers. Oocytes were washed in TCM-199 supplemented with fetal bovine serum (FBS) and FSH, then distributed in maturation media (TCM-199 supplemented with FBS, FSH and gentamicin). Three experimental groups of α-tocopherol (50, 100 and 200 mM) and a control group without α-tocopherol were used. Maturation was carried 22 h at 38.5°C in a 5% CO2 atmosphere. Oocytes were examined to determine cumulus expansion as categorical data (expansion or no expansion), as well as cumulus expansion Index (CEI). For CEI determination oocytes were graded 0 to 4, being 0 those with null expansion and 4 those with a noticeable cell expansion, then the number of oocytes were multiplied by the grade given and a sum of the totals was obtained, the new total was divided by the total of oocytes in the group and the result obtained corresponded to the CEI of the group. Results were analyzed with Chi Square test (for maturation rates) and an ANOVA (for the CEI) using the SAS system, data are presented as mean ± standard error. There was no statistical difference between control and α-tocopherol groups (P >0.05). Numerically, the control group showed a higher maturation rate (100%) and obtained a higher CEI (2.44±0.20), followed by the 50 mM group (98.16%; 2.39±0.13), the groups 200 mM (97.40%; 2.00±0.14) and 100 mM (96.25%; 2.06±0.24) were the lowest. The addition of the minimum concentration (50 mM) of α-tocopherol to the maturation media could improve maturation rates without exposing oocytes to toxic effects.

Abstract Background Musculoskeletal disorders (MSD) are a common health problem among dentists. Dental treatment is mainly performed in a sitting position. The aim of the study was to quantify the effect of different ergonomic chairs on the sitting position. In addition, it was tested if the sitting position of experienced workers is different from a non-dental group. Methods A total of 59 (28 m/31f) subjects, divided into two dentist groups according to their work experience (students and dentists (9 m/11f) < 10 years, dentists (9 m/10f) ≥ 10 years) and a control group (10 m/10f) were measured. A three-dimensional back scanner captured the bare back of all subjects sitting on six dentist’s chairs of different design. Initially, inter-group comparisons per chair, firstly in the habitual and secondly in the working postures, were carried out. Furthermore, inter-chair comparison was conducted for the habitual as well as for the working postures of all subjects and for each group. Finally, a comparison between the habitual sitting posture and the working posture for each respective chair (intra-chair comparison) was conducted (for all subjects and for each group). In addition, a subjective assessment of each chair was made. For the statistical analysis, non-parametric tests were conducted and the level of significance was set at 5%. Results When comparing the three subject groups, all chairs caused a more pronounced spinal kyphosis in experienced dentists. In both conditions (habitual and working postures), a symmetrical sitting position was assumed on each chair. The inter-chair comparisons showed no differences regarding the ergonomic design of the chairs. The significances found in the inter-chair comparisons were all within the measurementerror and could, therefore, be classified as clinically irrelevant. The intra-chair comparison (habitual sitting position vs. working sitting position) illustrated position-related changes in the sagittal, but not in the transverse, plane. These changes were only position-related (forward leaned working posture) and were not influenced by the ergonomic sitting design of the respective chair. There are no differences between the groups in the subjective assessment of each chair. Conclusions Regardless of the group or the dental experience, the ergonomic design of the dentist’s chair had only a marginal influence on the upper body posture in both the habitual and working sitting postures. Consequently, the focus of the dentist’s chair, in order to minimize MSD, should concentrate on adopting a symmetrical sitting posture rather than on its ergonomic design.

Clinicians should appreciate the effectiveness of virtual reality (VR) headsets for managing both the anxiety and the behaviour of non-cooperative paediatric patients who require treatment over several dental appointments. The aim of this study was to assess the effectiveness of using a VR headset as a distraction for managing the anxiety and behaviour of paediatric patients during their dental treatment. Eighty patients, aged between five and ten years old and who required dental treatment over three or more appointments, were randomly allocated into two groups. One group used a VR headset during all their appointments, and the other one did not use any distraction technique. The patients were asked to take a Facial Image Scale Test during their first and last appointments to assess their level of anxiety. Additionally, the dentist completed the Frankl Test to quantify the child’s behaviour at the beginning and the end of their treatment. The results obtained, both from the group using the VR headset and from the control group, were compared using the chi-square test. The use of a VR headset during dental treatment significantly reduced anxiety (95% of the children were happy) and improved behaviour (100% positive behaviour) as compared with the control group (40% and 57.5%, respectively). A VR headset can effectively distract a paediatric patient, helping to reduce anxiety and manage behaviour during dental treatment

Objective: Anxiety is regarded as a major problem in children undergoing dental treatment. One of the physiological responses to anxiety is an increased pulse rate. Young children respond aggressively to anxiety and are in need of psychological intervention. Pop-up books can be used as an instrument to improve their interest and to help them understand the substance of dental health education.The objective of this study was to utilize pulse rate measurements to investigate the intervention of a pop-up book in reducing anxiety. A total of 78 children aged 4–6 years were divided into two groups: An intervention group with the pop-up book Aku dan Gigiku and a control group without intervention. The pulse rates of both groups were measured. This study comprised an experimental clinical research design. The independent t-test was used to measure comparisons of decreased pulse rate between the two groups.Result: The result showed that there was a statistically significant difference in decreased pulse rate with and without the intervention of the pop-up book Aku dan Gigiku. Pop-up books are often used as an educational medium for children because they present interesting illustrations and are easy to understand.Conclusion: As a medium of dental health education, pop-up books can contribute significantly to reducing anxiety in children.

PURPOSE: To evaluate the bone healing of mandibular fractures following the use of Portland cement. METHODS: Thirty-two male Wistar rats were divided into control and experimental groups. In the control group the rats were submitted to a mandibular fracture, which was reduced, and the soft tissues were sutured. In the experimental group the rats had the mandibular fracture reduced and maintained with the Portland cement. The animals were euthanized 7 and 21 days after surgery by injecting a lethal dose of anesthetic. The following variables were studied: weight of the animals, radiographic images, histopathological features and time of surgery. RESULTS: A weight loss was observed in the specimens of both groups at the different times of evaluation, a greater difference in weight before and after surgery being found in the experimental group, which was statistically significant (p <0.05, p = 0.041). From the histological point of view, with a margin of error (5.0%) the only two significant differences (p <0.05) recorded in the variables were "Material deployed" and "Bone resorption" during the evaluations at 7 and 21 days, respectively. CONCLUSION: The Portland cement served to promote bone healing.
