The questionnaire included general questions, questions on how to organize patient interactions during professional oral hygiene, and questions specific to performing professional oral hygiene. Over 50% of the respondents were general practitioners and dentists, while the remaining 37.4% specialized in pediatric dentistry, surgical dentistry, and orthopedic dentistry.Results: Over 69% of specialists reported a high level of availability of visual aids for demonstrating oral hygiene rules at their workplaces. Forty percent of specialists in Moscow are fully equipped with everything necessary for oral hygiene, exceeding the results obtained in a survey of dentists in other regions. A significant number of patients with signs of gingivitis and periodontitis remain, with over 72.7% of respondents indicating that they perform oral hygiene specifically for this category of patients. The most common strategies for removing mineralized plaque by dentists in dental facilities across the Russian Federation include ultrasonic scalers, Air-Flow technology, and circular brushes with pastes of varying abrasiveness. The Vector system is more accessible to dentists in larger cities. Perio tips, glycine/erythritol powders, and hand curettes are used by an average of 8.5% of specialists.Conclusion: The primary approach to improving and maintaining oral hygiene will likely remain individualized recommendations from a dentist tailored to the patient's needs, as noted by 32.8% of respondents.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"105 3","pages":"54-59"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148279143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both drugs were two-component systems that seal the dentinal tubules to treat dentine hypersensitivity.Material and methods: The study included 18 teeth extracted from the volunteers. The age of the patients ranged from 42 to 65 years. Diamond discs were used to prepare the tooth slices, and then the teeth were chipped with a chisel. The GF and DVL groups included 6 tooth chips. X-ray fluorescence elemental analysis was performed using a scanning electron microscope with an energy dispersion analyzer. The elemental analysis was performed on the most common chemical elements in tooth tissues and studied preparations: calcium, phosphorus, oxygen, fluorine, silicon, magnesium, copper, iron, sodium and sulfur.Results: A \"composite\" consisting of fluorides and silicates of calcium and magnesium was found on the surface of the teeth chips treated with DVL and GF. These compounds occurred during a chemical reaction between the two main components of these drugs, calcium hydroxide and magnesium fluorosilicate. In addition, the samples treated with DVL contained calcium sulfate and cuprate, the product of the reaction of copper sulfate with calcium hydroxide, as well as sodium fluoride, the product of the reaction with calcium hydroxide of sodium fluorosilicate.Conclusion: The chemical composition of the Dentin sealing liquid includes, in addition to the obturating and antimicrobial components, easily soluble sodium fluoride. The absence of sodium fluoride in the sealing composite material indicates its greater uniformity and, consequently, higher stability in an aqueous solution. The presence of sodium fluoride plays a negative role in the formation of a sealing desensitizing composite.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"105 2","pages":"9-16"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147783905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After the cystectomy operation, the biopsy material was examined in the In cased when malignancy was suspected after a standard histological examination, immunohistochemical examination with markers of proliferative activity (Ki-67) and cytokeratin (CK15) was performed using an Autosteiner 360 according to the Quanto protocol program using the PrimeBioMedTM .detection system. The expression of the Ki-67 marker was determined by the percentage of cells with stained nuclei to the total number of nuclei in 3 non-overlapping fields of view on an Axioplan 2 Imaging microscope at x400 magnification.Results: In the case of a benign process, proliferative activity of Ki-67 was noted in the basal layer of the epithelial lining, while no cell proliferation was observed in the overlying cellular layers. In the case of in situ carcinoma and squamous cell carcinoma, IHC examination revealed a high (50-60%) proliferative activity of Ki-67 cells, observed in all layers of the epithelial lining. Cytokeratin 15, which characterizes proliferating epithelial cells in the case of a benign process, was detected in the basal layer of the multilayer squamous epithelium. The expression of cytokeratin 15 in carcinoma in situ showed an uneven pattern in the tumor epithelial cells. In the examined cases of squamous cell carcinomas, the expression of this marker was characterized by a progressive diffuse signal in the tumor cells, depending on the increasing histological grade of the tumor.Conclusion: Thus, in order to exclude malignant transformation in the lateral cyst wall, the diagnostic algorithms should include an immunohistochemical study with markers on Ki-67 and CK15.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"105 5","pages":"62-69"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149246603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the physicochemical properties and radiation stability of biodegradable membranes based on polylactic acid (PLA) and its copolymers (PLGA) for potential use in guided bone regeneration (GBR) in maxillofacial surgery.Materials and methods: Membranes made of pure PLA, PLA with hydroxyapatite (PLA/HAP), and polylactic-co-glycolic acid (PLGA) in 85:15 and 60:40 ratios were studied. Samples were sterilized using electron beam irradiation at a dose of 25 kGy. Degradation was carried out in phosphate-buffered saline at 37 °C. Molecular structure was assessed by FTIR spectroscopy, and surface morphology was evaluated using scanning electron microscopy (SEM).Results: After one month, PLGA 60:40 samples lost approximately 40% of their mass and structural integrity and were excluded from further observation. PLGA 85:15 samples maintained shape and exhibited a minor mass loss (~5%). Non-irradiated PLA/HAP composites showed variable mass loss (0-19%), while irradiated ones displayed minimal changes (up to 2%). Pure PLA samples remained the most stable throughout the 2.5-month observation period, showing only minor hydrolytic surface alterations. Radiation sterilization did not cause significant changes in the molecular structure of any tested materials.Conclusion: PLA copolymers demonstrated controlled degradation rates and sufficient structural stability, making them promising candidates for the development of patient-specific resorbable membranes for GBR. Their predictable resorption profile may eliminate the need for secondary surgery to remove the membrane. The results support the feasibility of using ionizing radiation for sterilization without compromising material properties.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"105 1","pages":"21-30"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147310983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dental SAND PRO material is positioned as a ceramic-filled polymer material designed for 3D printing of temporary crowns and bridge-like structures for long-term wear. As part of the experimental part of the work, models were developed and manufactured for conducting a series of comparative compression tests. Two modern production technologies are compared: milling from ready-made factory blocks (CAD/CAM) and 3D printing.Results: Tests have shown that structures made of HUGE PMMA Monolayer material using CAD/CAM technology have higher mechanical strength compared to crowns made of HARZ Labs \"Dental Sand Pro\" material made by 3D printing. The destructive load of milled samples from HUGE PMMA is 2-4 times higher. Model molar crowns also had higher values for milled samples. Bridge-like prostheses made by milling could withstand about 1600 N, and 3D printing - about 500 N (p<0.05).Conclusion: Temporary structures made by milling from ready-made polymer blocks have a sufficient margin of safety for use in all areas of the dentition. In turn, 3D-printed structures, due to their lower strength characteristics, should be used mainly in the area of frontal teeth and premolars, where the load is significantly.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"105 3","pages":"10-14"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148279050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
