Relevance. Advanced clinical and cytological studies have not been conducted yet to examine denture adhesive effect on the prevention of inflammatory changes in the mucous membrane of the prosthetic bed, and thus, the prevention of denture-related stomatitis. Purpose: to assess the clinical and functional condition of the oral mucosa beneath the denture during the adaptation period using a denture adhesive cream to prevent inflammation of the denture bed mucous membrane.Materials and methods. The study clinically and cytologically (washing, scraping) assessed the condition of oral mucosa beneath complete acrylic dentures on days 14-16 and 28-30 of the adaptation period in 15 fully edentulous patients (main group), who used an adhesive cream after they were delivered their dentures, and in 21 fully edentulous patients (control group) who did not use the cream during the denture adaptation period. All the patients were elderly.Results. At different times of the adaptation period, the study more frequently detected inflammatory changes in the denture-bearing mucosa in subjects who did not use the denture adhesive cream. The cytological study confirmed the results of the oral clinical examination, as, at the end of the adaptation period, the number of cellular elements and various microorganisms was significantly lower in the main group than in the controls, which proved the effectiveness of the denture adhesive cream for the prevention of denture stomatitis.Conclusions. Regardless of sex, patients with complete acrylic dentures, who used a denture adhesive cream, had a lower bacterial accumulation on the prosthetic bed and inflammatory changes during the adaptation period, which allowed us to recommend the adhesive cream for the prevention of denture stomatitis.

Denture stomatitis is a multifactorial pathological condition of the oral mucosa that affects up to 72% of denture wearers. It is commonly seen on the palatal mucosa and characterized by erythema on the oral mucosa that are in contact with the denture surface. The aim of this study was to incorporate 2-methacryloyloxyethyl phosphorylcholine (MPC) and dimethylaminohexadecyl methacrylate (DMAHDM) into a high impact polymethylmethacrylate heat-cured denture base acrylic resin as a potential treatment for denture stomatitis. We used a comparative study design to examine the effect of incorporating MPC as a protein repellent agent and DMAHDM as an antifungal agent to prevent the adherence of Candida albicans to the denture base material. The dual incorporation of MPC and DMAHDM reduced C. albicans biofilm colony-forming unit by two orders of magnitude when compared to the control group devoid of the bioactive agents. Although the addition of MPC and DMAHDM alone or in combination significantly reduced the flexural strength of the material, they showed reduced roughness values when compared to control groups. This new denture acrylic resin provides the benefit of enhancing C. albicans biofilm elimination through dual mechanisms of action, which could potentially reduce the prevalence of denture stomatitis.

The aim: Is to evaluate the effectiveness of the proposed method of constructing occlusal surfaces of orthopedic structures by monitoring the dynamics of functional indicators of occlusion and the functional condition of the masticatory muscles. Materials and methods: The object of the study was made up by 64 patients with included defects of the dentition of the 3rd class according to Kennedy. Patients were divided into two equal groups – the main group (patients were treated by using the suggested method of construction of occlusal surfaces of orthopedic structures) and control (dentition defects were replaced according to the traditional protocol). Results: The results of evaluating the effectiveness of the proposed method showed that the index of symmetry of the anterior bundles of the temporal muscles dropped by 18.5%, the index of symmetry of the masticatory muscles reduced by 22%, the torque of the mandible reduced by 32%, the index of stabilizing occlusal – by 27%, relative efforts of balance disturbance for more than 10 % regarding the left and right reduced by a factor of 4.4, the rate of opening time was 1.5 times higher than before, the rate of time of opening of the jaws – 1.8 times. Conclusions: The use of the suggested method of orthopedic treatment with temporary structures leads to probable changes in the studied functional parameters in comparison with the control group (p <0,05).

e17530 Background: It is believed that hypoxia-inducible factor (HIF-1α) hyperactivity promotes synthesis of protective factors and increases bacterial growth-inhibitory activity, provides enhancement methods of the congenital immune response to microbial infection. Methods: Lactoferrin and α-defensin were detected in saliva of 41 patients with oral mucosa (OM) cancer (T2N0-2M0) before a comprehensive treatment; enzyme immunoassay (EIA) method was used. A level of hypoxia-inducible factor (HIF-1α) was evaluated by EIA method in tumor tissues after surgical treatment. The patients were divided into two groups according to an after-surgery period: the main group (n = 16) had after-surgery suppurative complications. An after-surgery period proceeded without infectious complications in patients of a control group (n = 25). Results: It was found that Lactoferrin content in saliva statistically was significantly higher by 36,4% (p < 0,05) (3,0±0,24 µg/ml against 2,2±0,19 µg/ml) if to draw a comparison between the main group and the control group with respect to development of suppurative complications and absence of a inter-group difference according to α-defensin concentration (4,1±0,35 pg/ml against 3,8±0,19 pg/ml). HIF-1α expression index in the main group (8,4±0,79 CU/mg protein in a well) exceeded this index by 18,3% (p < 0,05) in the control group (7,1±0,79 CU/mg protein). A positive correlation between HIF-1α expression and Lactoferrin content (R = 0,53 at р = 0,0001) was detected in patients with OM cancer. Conclusions: Detected HIF-1α hyperexpression in tumor tissues and Lactoferrin content in saliva, as well as their interaction allows suggesting significance of these factors for their progression prediction in patients with OM cancer in case of after-surgery suppurative complications.

The search for and the application of available noninvasive methods for early diagnosis of oral mucosa (OM) neoplasia is a clinically significant problem. The aim of this study was to evaluate the effectiveness of the original score-based algorithm for assessing clinical data generated by a conventional and an autofluorescencebased examination in diagnosing OM cancer and assessing indications for a biopsy. We analyzed 134 medical histories and pathology reports of patients with oral neoplasia. The patients were assigned to 2 groups: the control group included 63 patients who underwent a standard visual and tactile examination with history taking and then were referred for an incisional biopsy followed by a histopathological examination of the specimens. In the main group consisting of 71 patients, a standard visual and tactile examination was complemented by an autofluorescence-based examination and the original score-based algorithm with the original index of required histopathological verification (RHV) were used to assess indications for a biopsy. In both groups, the most commonly affected site was the tongue (72.4%). The histopathological examination revealed that 28 patients from the main group and 14 patients from the control group had OM cancer (р = 0.051). Histologically, early-stage cancer was diagnosed in 17 patients from the main group and in 4 patients from the control group (р = 0.004). The proposed algorithm allowed us to effectively (in 90% of cases) diagnose precancer and cancer and avoid unnecessary biopsies.

We studied the autopsy material obtained from 7 children who died in the neonatal period in order to evaluate the composition of lymphocytes of the intestinal mucosa against the background of morphological changes in the tissues of the gastrointestinal tract in newborns with sepsis. The main group consisted of 4 children with neonatal sepsis, the control group – of 3 newborns who died from other causes. The research material included the specimen of the small and large intestine.Results. Small intestine: it was found that there were less CD4 + lymphocytes in the small intestinal mucosa in the group of children who died from neonatal sepsis in 75% of cases than in the control group, but this difference was not statistically significant (p=0.1). There were no differences in the number of CD8 + and CD20 + cells in the studied groups. Large intestine: the number of CD4 + lymphocytes of the mucous membrane of the colon was greater in the main group of children than in the control group (p=0.03). An increase in the number of CD4 + cells was registered in 3 of 4 cases of neonatal sepsis. The number of CD8+ and CD20+ lymphocytes in the studied groups was the same (р>0.05).Conclusion. The increase in T-lymphocytes CD4+ in the mucous membrane of the large intestine is probably connected with the antigenic stimulation of opportunistic intestinal bacteria. We found no morphological signs of the suppression of the cells of adaptive immunity associated with the intestinal mucosa.

Aim. To assess the effect of dynamic electroneurostimulation in treatment of community-acquired pneumonia in preschool children. Methods. The main group consisted of 45 preschool children with community-acquired pneumonia, in whom 7-day treatment course of dynamic electroneurostimulation was included as the component of the complex treatment. The control group included 55 children in whom conventional tactics was applied. Results. General intoxication syndrome was resolved at 3.2±1.1 day in children of the main group compared to 7.7±1.4 day in the control group. The use of dynamic electroneurostimulation reduced the duration of respiratory distress by more than 1.5 times (6.8±1.3 day), regression of physical lung changes was observed at 10.3±1.4 on average, compared to the end of the second week at the control group. Resolving of the clinical symptoms in children of the main group was accompanied by statistically significant (p 0.05) reduction of basic parameters of systemic inflammation (increased white blood cells count, high neutrophil count, left shift) by 7th day of treatment. The level of C-reactive protein reduced by 7 times in children of the main group, compared to 2.3 times in comparison group (p 0.05). Chest X-ray on the 7th day showed complete resolving of inflammatory changes in 20 (44.4%) patients of the main group, while no such cases were observed in control group (p 0.001). At the same time, no positive change of X-ray picture was revealed in 25 (45.5%) children of the control group, while there were no such cases in the main group (p 0.001). On the 11th day of treatment complete resolving of inflammatory changes was found in 43 (95.6%) children of the main group, compared to 34 (61.8%) children of the control group (p 0.05). Conclusion. Including of dynamic electroneurostimulation in complex treatment of community-acquired pneumonia in children reduces the recovery time, hospital stay and treatment cost.

The aim of the present study was to assess the effect of a denture adhesive (DA) on patient satisfaction and kinesiographic parameters of complete denture wearers by a cross-over study. Fifty edentulous patients received a set of new complete dentures. After an adaptation period, the participants were enrolled in the trial and randomized to receive a sequence of treatment protocols: Protocol 1- DA use during the first 15 days, followed by no DA for the next 15 days; Protocol 2- no DA during the first 15 days, followed by use of DA for the next 15 days. Outcomes were assessed after 15 days of each sequence of treatment. A questionnaire was used to assess the patients´ satisfaction. A kinesiograph was used to record mandible movements and patterns of maxillary complete denture movement during chewing. The Wilcoxon test (α=0.05) and a paired sample t-test (α=0.05) were used to compare satisfaction levels and kinesiographic data, respectively. Use of DA improved the overall level of patient satisfaction (p<0.001). The kinesiographic recordings revealed a significant increase (1.7 mm) in vertical mandible movements (p<0.001) during chewing and a lower (0.3 mm) vertical intrusion of the maxillary complete dentures (p=0.002) during chewing after using the DA. Use of DA in complete denture wearers improved the patients´ satisfaction and altered mandible movements, with increases in vertical movements during chewing and less intrusion of maxillary complete dentures.

Relevance: inflammatory processes in the oral mucosa are often found in diseases of the gastrointestinal tract, which is explained by the common functions and unity of all parts of the digestive system.Purpose – to study the effect of the studied drugs on the state of antioxidant-prooxidant systems of the oral mucosa in patients with chronic pancreatitis.Materials and methods: we examined 118 patients, of whom 62 were men (mean age 39.6 ± 16.4 years) and 56 women (mean age 40.3 ± 15.7 years); of these, 34 patients (control group) are practically healthy people without somatic pathology and 84 patients with chronic pancreatitis who were divided into two groups. The first (main) group - 46 people who, in addition to the drug therapy prescribed by the gastroenterologist, were prescribed the drug “Multiflora” 1 tablet 1 time per day with meals for 30 days. Also, the patients of the main group, after each meal, rinsed their mouths with “Enoant” food concentrate at a dilution of 1: 5 and applied it inside with 1 tablespoon 2 times a day, diluted with water in a ratio of 1: 5. The second (comparison group) - 38 people who, in addition to treatment of chronic pancreatitis, were treated with the oral mucosa according to the generally accepted method - prescribed fluconazole 150 mg 1 time a day, rinsing with 2% borax solution in glycerol after eating for 14 days. Unstimulated oral fluid of the examined patients served as the material for the study. In all groups, the activity of the catalase enzyme was determined by the method of S.V. Girina (1999), the level of malonic dialdehyde (MDA activity by reaction with thiobarbiturate acid to form a trimethine complex) and antioxidant-prooxidant index of unstimulated oral fluid by the method of А.P. Levitsky (2010). Laboratory research was carried out at the time of the initial examination before the start and on the 30th day of treatment.Results: in the comparison group after treatment, an increased concentration of malondialdehyde in the oral fluid, as well as reduced indicators of the API index and catalase activity confirm the presence of inflammatory processes in the oral mucosa. The application of the proposed therapeutic complex to patients of the main group significantly reduces the concentration of malondialdehyde in the oral fluid, proving its anti-inflammatory effect on the oral mucosa. An increase in the antioxidant-prooxidant index and an increase in catalase activity indicates an increase in the body’s defenses in patients of the main group.Conclusion: the use of the proposed therapeutic complex in patients with inflammatory diseases of the oral mucosa suffering from chronic pancreatitis contributes to the elimination of inflammatory and degenerative processes and the restoration of the normal level of protective systems in the oral mucosa.

Objective to refine the method of incisional biopsy in the diagnosis of oral mucosa cancer using the auto-fluorescent stomatoscopy. Materials and method.The study was conducted on the base of the Samara Regional Clinical Oncology Center. The inclusion criterion for patients was the diagnose of the oral mucosa cancer of various localization. Patients were divided into 2 groups. The main group included patients (n=43), who were being diagnosed for cancer with the help of optimized incisional biopsy of the oral mucosa formations, using the "AFS-400" autofluorescence complex and glasses with a green light filter for identification. The patients of the control group (n=46) received the standard biopsy procedure under direct vision. Results.The first incisional biopsies revealed cancer in 25 (54%) patients of the control group and in 36 (84%) patients of the main group. A histological verification of the diagnosis was necessary in 7 (16%) patients of the main group and required the second biopsy. In the control group, for the same purpose, 17 (37%) patients underwent the second biopsy and 4 (9%) patients required the third biopsy procedure. Exophytic-papillary forms of cancer were the most complex for histological verification. The primary biopsy of these cases was effective in 16 (37%) patients in the main group and in 8 (17%) patients in the control group (p = 0.036). In patients with initial stages of cancer (I-II), with the first incision biopsy, the histological verification of cancer was achieved in 16 (37%) cases in the main group and in 8 (17%) cases in the control group (p = 0.036). Conclusion.The use of the "AFS-400" autofluorescent complex and glasses with a green light filter for incisional biopsy of oral mucosal formations allows histological verification of cancer with the first biopsy in 84% of cases, including in stages I - II in 16 (37%) cases and in exophytic papillary forms in 16 (37%) cases. The significant difference was registered for the similar indicators of the control group (p = 0.036).
