Patients are divided into three subgroups depending on the position/size of the jaw bones and the main link of pathogenesis. The parameters of TRG and CBCT sections were measured before and after treatment. Various parameters were used for the analysis: skeletal (SNA, SNB, ANB, etc.), dental (II/SN, II/ii, APog-I, APog-i, etc.), skeletal profile and soft tissue parameters.Results: Various orthodontic techniques have been applied, including FNTA, the Damon bracket system, the Biederman apparatus and others. In the retention period, non-removable retainers in the frontal section and removable night retention devices of various structures were used. Patients were monitored for up to 15 years after the completion of the active orthodontic treatment stage. The analysis of the X-ray examination data indicates the normalization of the mutual position of the jaw bones in relation to the base of the skull, optimization of the ratios of the bone elements of the TMJ. An algorithm has been developed for the treatment of patients with dental anomalies in the sagittal plane, with narrowing of the upper jaw during the bite of permanent teeth.Conclusion: Comprehensive treatment of patients with distal occlusion during the period of active skeletal growth makes it possible to achieve significant improvements in dentition, position and closure of teeth, as well as skeletal parameters of X-ray examinations. The results indicate the importance of early intervention using modern orthodontic techniques. Long-term follow-up in the retention period shows the stability of the results and the effectiveness of the treatment.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"103 5","pages":"24-36"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142476559","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}

The patients underwent standard PET-CT examinations in the «whole body» mode, and the density of the mandible was examined on CT. Radiation therapy was performed by intracavitary administration of strontium 89 chloride; remote radiation therapy with cisplatin radiomodification. In the presence of bone metastases, patients received complex supportive therapy with zolendronic acid. The effect of zolendronic acid on the density of the mandible in the frontal and lateral sections was studied by multidimensional dispersion analysis.Results: Statistically significant differences (p=0.002) were revealed for density indicators according to CT scans of the mandible in the frontal region against the background of zolendronic acid therapy. We attribute the absence of statistically significant differences for the density of the mandible in the lateral sections (p=0.101 and p=0.082) against the background of zolendronic acid therapy to a measurement bias. We attribute the absence of statistically significant differences in density indices against the background of hormonal, radiation, targeted and chemotherapy to the design of the study.Conclusion: Density measurement based on CT examination data can be recommended for use as an additional tool in assessing the effect of zolendronic acid on the density of the mandible.

The study showed that in most patients with erosive-ulcerative and bullous forms of lichen planus, the accumulation of the photosensitizer in the lesions on the oral mucosa increased as the exposure time increased from 20 to 30 minutes. The fastest accumulation of the photosensitizer occurred in the areas of mucosal lesions with the most pronounced vascularization, namely, in the area of the tongue and the bottom of the oral cavity.Conclusion: Using the method of local fluorescence spectroscopy, the kinetics of accumulation and destruction of photosensitizer in pathological areas of the oral mucosa was determined, and therefore the optimal time of laser exposure to the lesion was determined.","PeriodicalId":35887,"journal":{"name":"Stomatologiya","volume":"103 1","pages":"12-15"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139900586","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 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}
