After a written agreement to participate in the study, an oral examination was performed and the examination data were marked on the map. When determining the topography of dentition defects, the classifications of E. Kennedy and E.I. Gavrilov were used, the presence and type of dentures were noted. Statistical processing of the results was carried out using the SPSS Statistics 25.0 program.Results: Dentition defects were found in 91.3% of the subjects, complete absence of teeth in 0.4%, and 7.7% of the subjects had complete dentition. With an increase in the age of the subjects, there was a tendency to a predominance of terminal defects (80.8% aged 45 to 74 years). Regardless of age, defects in the anterior parts of the dentition were less common. Of the study participants, 209 (51.0%) had dentures, 97.1% wore removable structures. Acrylic and nylon prostheses prevailed among removable structures (97.0%), only 6 participants had clasp structures. Of the 410 examined with dentition defects, 201 (49.0%) did not have dentures and needed prosthetics after rehabilitation and special preparation of the oral cavity for prosthetics.Conclusion: The reasons leading to early tooth loss and the most commonly used prosthetics methods are related to the economic level of the country's development, the lifestyle of the population, the state of sanitary and educational work and the low level of prevention of oral diseases. Comprehensive budgetary preventive measures in a particular region of the country are important for reducing oral diseases, aimed not only at reducing the incidence rate, but also at raising public awareness about oral health.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"103 6","pages":"25-29"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142865408","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}

There are eight generations of foreign-made adhesive systems for the restoration of teeth. However, until now, in orthodontics, the development of domestic adhesive systems with improved properties of adhesion of brackets to tooth enamel still important, especially in the posterior teeth.Objective: The purpose of this work was to study the shear strength of fifth generation domestic adhesive between metal brackets and the enamel of molar teeth in laboratory conditions.Material and methods: The study included 17 specimens of extracted maxillary molars embedded in acrylic resin blocks. Brackets from G&H Orthodontics (G&H Wire Company, USA) were fixed to the tooth enamel using the domestic Compofix (ortho) set. The enamel was treated with etching gel (37% phosphoric acid) for 30 seconds. Then the gel was washed off with water and the surface of the enamel was thoroughly dried. A primer was applied to the prepared surface with an applicator, inflated with a weak air flow for 5-10 seconds and photopolymerized for 20 seconds. The surface of the bracket was treated with degreaser, then a thin layer of adhesive was applied, and the sample was fixed to the enamel. Excess material was removed with an applicator. The samples were photopolymerized for 20 sec. Then, the shear bond strength of the adhesive was determined according to the method of GOST 31574-2012 on a (Zwick/Roell Z010 testing machine, Zwick, Germany).Results: The shear strength of the adhesive joint obtained during the test is 13.54±1.01 MPa, the average value of the index of adhesive residues on the surface of the bracket was 23%±4%, which corresponds to the standard average values according to GOST.Conclusion: The tested domestic adhesive system of the fifth generation can be recommended for the practical work of an orthodontist.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"103 1","pages":"5-7"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139900535","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}

Today, the application of artificial intelligence has made it possible to automate work processes, increase the accuracy, speed and efficiency of solving the issues of forensic dentistry, and improve the quality of forensic evidence provided. At the same time, like any technology, artificial intelligence is not without some disadvantages of practical application. In this regard, the opinion is expressed that it is advisable to use artificial intelligence systems only as an auxiliary tool, leaving the primary role in making final decisions to forensic medical examiners. Thus, the potential of development and prospects of practical application of artificial intelligence to solve the issues of forensic dentistry and improve the quality of the provided forensic evidence remain very promising.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"103 6","pages":"79-82"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142865848","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}
