X-ray examinations were used to analyze compliance with the basic requirements of clinical guidelines for modeling pin inlays on the root surface. For this purpose, the X-ray assessment of CBCT studies of maxillary and mandibular teeth and the conclusions of the forensic medical examination were analyzed. The results of the forensic medical examination in cases related to the poor-quality manufacture of this type of prosthesis in the period from 2013 to 2022 were analyzed. The results showed that in 10% of lawsuits related to non-removable prostheses, there were claims about the quality of the prosthesis. This share has not decreased over the past 10 years, and the lawsuits concerned the quality of manufacture of root canal tabs. At the same time, errors and complications when using tabs in root canals were identified in 50% of cases, and in 50% of cases they were associated not with poor-quality materials or imperfect treatment techniques, but with incorrect dental technique. An X-ray assessment of the quality of the formation of root canal inlays by dentists showed very low compliance with clinical recommendations. Compliance with clinical guidelines is very low. The correct residual wall thickness of the root canal was determined only in the following cases, the correct residual wall thickness of the root canal was determined only in 37% of cases. The recommended ratio of the tab pin length (2/3 of the root length) was determined only in 2% of cases. Compliance with the ratio of crown and root length for restored teeth was required only in 2% of all studied cases. The ratio of crown height to inlay pin length was 1:2 or 1:3 in only 2% of cases.
Chronic apical periodontitis is a focus of chronic poisoning and sensitization of the body and poses a potential health hazard. Treatment of chronic apical periodontitis is one of the most important problems faced by dentists in their practice. Conservative treatment is aimed at removing microflora, stimulating regenerative processes in the periapical region and completely closing the root canal system and periodontal tissues to prevent re-infection. In addition, this method is the least traumatic for the patient. The question of the influence of tools and agents on destructive processes in the periapical root canal has been widely discussed for a long time and to the present.
The wing mounting angles are the angles of its installation to the bottom of the furrow ε_КР and to the direction of motion in the plane touching the ploughshare-moldboard surface in the area of the upper edge of the wing. To reduce the traction resistance of the canal digger, when choosing the installation angles of the wing, one should proceed from the condition of reducing the angle of capture of the seam by the moldboard . It is known from the theory of the share-moldboard surface that the angle has a very significant effect on the traction resistance of the tool.

Spina bifida-is a defect in the development of the neural tube, which is a splittinq of the spinal canal and is one of the most common conqenital malformation of the fetus. Worldwidt, the incidence of fetal neural tube defects ranqes from 0,17 to 6,39 per 1000 newborns. This article describes methods for early diaqnosis of fetal neural tube malformation in earle preqnancy and the results of studies of preqnant woman at different staqes of preqnancy.
Diabetes mellitus is a common endocrine disease, which belongs to the risk factors for the development of changes in periodontal tissues. The presence of diabetes mellitus in patients can cause the development of structural and functional changes in the maxillofacial area, and also increase the risk of changes in the tissues of the parodontium. At the same time, the nature of these changes and the degree of influence of diabetes mellitus on the state of the tissues of the parodon are 46 insufficiently studied. In this regard, it is necessary to pay great attention to this problem in order to provide timely assistance to these patients in order to avoid rather serious complications
This article analyzes some aspects of the construction of water facilities in the Kokan Khanate, water facilities built in the territory of the Khanate in the 18th and 19th centuries, their use, farming culture, water distribution and management rights. The measures of Erdonabi, Norbotabi, Olimkhan, Umarkhan, Muhammad Alikhan’s regarding agrarian issues are discussed
Dysplasia is the most common form of morphological precancer of the cervix. Cytological smear from the cervical canal is one of the most effective methods for diagnosing cancer, background processes and precancerous conditions of the cervix at the very initial stages of occurrence. Histology allows you to determine the degree and form of epithelial damage, to detect the presence of atypical cells. The material for the study was targeted incisional biopsies from the cervix of 847 patients aged 19-73 years. All biopsies were stained with hematoxylin-eosin. Microscopic examination was performed using a conventional light microscope "Leica". The analysis of biopsy materials of 847 patients shows that 1/5 of the patients (20.8%) had dysplasia of varying severity. The highest peak of morbidity with this pathology occurs at the reproductive age, which makes this problem even more relevant for comprehensive study and discussion in a wide range of specialists. A comprehensive study of background and precancerous diseases is a great opportunity to detect the disease in time or prevent its occurrence. Therefore, every woman needs to undergo such a survey.
In contrast to anatomical variants, congenital malformations - synonymous with anomalies or dysplasia - are characterized by deviations not only from normal anatomical development but also from regular function. They can result from delayed development, abnormal embryogenesis or both due to spontaneous genetic mutations - this occurs in most congenital malformations of the outer and middle ear - genetic transmission and exogenous factors in about 10% of cases.
Klinik amaliyotda stomatologlar ko'pincha endodont va parodont to’qimalarining birlashgan zararlanishiga duch kelishadi. Ushbu holatlar endodontoperodontal shikastlanishlar (EPSH) deb ataladi va endodont va parodontdagi yallig'lanish va destruktiv o'zgarishlar bilan kechadigan parodontal kasallikning kombinirlangan shikastlanishini anglatadi. Ushbu murakkab patologiya shifokor uchun diagnostika nuqtai nazaridan muhim muammolarni keltirib chiqaradi va ularning klinik ko'rinishlari, endodontiya va parodontologiyada diagnostika va davolash tamoyillari to'g'risida keng bilim va tushunishni talab qiladi. Parodontal to'qimalarda yallig'lanish jarayoni tishlarning pulpasiga sezilarli ta'sir ko'rsatadi: II darajali umumiy parodontit bilan pulpada qaytarilmas o'zgarishlar tishlarning 54-56 foizida aniqlangan. Parodont, pulpa va periodontdagi surunkali yallig'lanish odontogen o'chog’i sifatida qaraladi, bu esa o'z navbatida surunkali stomatogen o'choqning tarkibiy elementi hisoblanadi. Ushbu muammolarni hal qilish bu sohadagi tadqiqotchilar uchun dolzarb hisoblanadi.
Endodontics is considered one of the most successful areas in dentistry. With careful cleaning, shaping, debridement and obturation of the root canal system, it is possible to achieve a successful outcome in the initial treatment in approximately 94% of cases.
