Purpose — to determine the values of central corneal thickness (CCT) in children depending on the level of intraocular pressure
(IOP) and the stage of congenital glaucoma (CG).
Material and methods. Clinical studies were carried out in the eye department of the clinic at the Tashkent Pediatric Medical In-
stitute. The study involved 18 patients (36 eyes) aged 9 to 11 years (mean age 9.3±1.6 years) with confirmed diagnosis of CG.
All patients underwent basic ophthalmologic examination prior to surgical and conservative treatment. In addition to basic meth-
ods, axial eye length and CCT were determined using an automatic non-contact tonometer/pachymeter manufactured by NIDEK
(USA).
Results. Analysis of the obtained data showed that in initial, moderate and advanced stages of glaucoma, the CCT values were sig-
nificantly lower than the age norm values. This indicates stretching of the fibrous capsule and thinning of the cornea in glaucoma.
In terminal stage CG, the CCT values practically did not differ from the age norm, but were higher than in initial, moderate and ad-
vanced stages of the disease. The noted thickening of the corneal membrane in terminal stage may be explained by edema of the cor-
neal tissue as a result of elevated IOP.
Conclusion. The age norm values of CCT should be taken into account when characterizing the severity of glaucomatous process
in children. Compared to the age norm, the cornea is significantly thinner in children aged 9 to 11 years with initial, moderate
and advanced stages of CG, and becomes significantly thicker in terminal stage, which is associated with edema caused by ele-
vated IOP.
Tug'ma glaukoma bilan og'rigan bolalarda ko'zning biomexanik ko'rsatkichlari uning turli bosqichlari bilan o'rganildi. Oddiy birlamchi tug'ma operatsiyasiz glaukoma bilan og'rigan 1 oydan 3 yoshgacha bo'lgan 20 bemor (40 ko'z) tekshirildi. Ulardan 1-guruhga (ilg'or bosqich) mos ravishda 7 (14 ko'z), 2-chi (ilg'or bosqich) - 8 (16 ko'z), 3-chi (terminal bosqich) 5 bemor (10 ko'z) kiradi. Tadqiqot usullari orasida visometriya, refraktometriya, oftalmoskopiya, optik diskni qazib olishni aniqlash, ko'zning old-orqa o'lchamini ro'yxatga olish bilan A-skanerlash, 5 g og'irlikdagi elastotonometriya; janubiy; 15d, shuningdek, Filatov-Kalf usuli bilan. Olingan ma'lumotlarning tahlili shuni ko'rsatdiki, elastokrivning ko'tarilish gradienti barcha guruhlarda qayd etilgan, ammo eng yuqori ko'rsatkich terminal bosqichi bo'lgan bolalar guruhida bo'lgan, ko'zning anteroposterior hajmi esa mos ravishda kattalashgan. kasallikning og'irligi bilan. Ko'z ichi bosimining oshishi kasallikning og'irligiga mutanosib ravishda qayd etilgan. Konjenital glaukomaning oddiy shakli rivojlanishi bilan ko'zning biomexanik ko'rsatkichlari bosqichlarga ko'ra ortadi. Shu bilan birga, tolali membrananing qattiqligining pasayishi ko'zning to'qimalarida morfologik o'zgarishlarni va glaukoma jarayonining zo'ravonligini ko'rsatadi.
Purpose: In this study, we aimed to compare the marginal fit of fixed dental restorations fabricated with the provisional prosthesis scanning technique versus a conventional impression technique and to determine the effect of both variables on the accuracy outcome. Materials and Methods: Twelve identical polyurethane edentulous maxillary models were equally divided into two groups: control (conventional impression group) and test (provisional prosthesis scanning group). After obtaining the impression using the above-mentioned methods and further preparing the final prosthesis, the passivity of the metal framework prosthesis was checked using a single screw test, i.e., only one screw was fixed on the terminal right abutment, and all others were empty. The marginal fit of the final prosthetic frameworks screwed onto the implants on the terminal left abutment was measured at the terminal right sight by periapical radiographs obtained immediately after metal framework placements in both groups. The medians derived from the two groups were compared using the Mann–Whitney test. In all tests, a p-value < 0.05 indicated statistical significance. Results: In the provisional prosthesis scanning group, the median marginal fit discrepancy was 170 µm (range 120–190). In the conventional impression group, the median marginal fit discrepancy was 1080 µm (range 1040–1100). There was a significant difference in the implant-framework marginal gap fit discrepancy between these two groups. Conclusion: Prostheses fabricated with the provisional prosthesis scanning technique are significantly more accurate than those fabricated with conventional impression techniques.
Transverzal okklyuzion anomaliyalarning yetakchi patognomonik alomati - transverzal tekislikdagi juft antagonist tishlarning jipslashuvining nomuvofiqligidir. Transverzal tekislikdagi juft antagonist tishlarning jipslashuvidagi nomuvofiqlik chaynash funksiyasining buzilishiga olib keladi, bu esa funksional chaynov markazining siljishida namoyon bo'ladi. Yoshlikda bu buzilishlar chaynashning yangi dinamik stereotipini rivojlanishiga olib keladi, o'sayotgan suyak to'qimalariga bosim kontsentratsiyasini o'zgartiradi va tish yoylarining shakli va konfiguratsiyasining buzilishining tezroq namoyon bo'lishiga olib keladi.

The paper considers as hubs for the transportation of products and individuals, as well as the advanced boondocks of a country, air terminals don't just assume a significant monetary part in present day culture, yet additionally enhance a local area's social and social attachment and variety. Concerning their effect on the regular and anthropological climate, they address a very energy-concentrated type of transport, which can force tremendous changes to the laid out connections and order. Worked to have an assortment of purposes and serve different clients' gatherings, enormous air terminal terminals advanced from open fields, to retail plazas, to metropolitan mixtures, having a functional size typically equivalent to that of a cutting edge city, yet of a disputable quality and with no particular region or populace. Security guidelines and market overviews have up until this point administered their plan, prompting the reception of a nonexclusive advancement design that further disengages them from the encompassing area, no matter what its improved availability.
To assess the hygienic status of the oral cavity depending on the treatment methods used. Material and methods: Under our supervision there were 92 patients with included and terminal defects of the dentition, who underwent prosthetics based on dental implants of the “DIO” system at the department of orthopedic direction of the FPC TGSI. Results: At the beginning of the study, the IGS was low in all three groups and corresponded to good implant hygiene. After 3 and 6 months, the index values were significantly worse and corresponded to the unsatisfactory implant hygiene. Patients of the 3rd group, who used the whole complex of individual and professional methods, had better indicators than in other groups. Conclusions: In patients using the irrigator, no signs of gingivitis were recorded for the entire observation period.
The length parameter of anterior-posterior axis is compared for children’s hyperopic eyes (302 eyes, hyperopia of 0.5 to 3.0 D). 109 eyes (109 children) with unilateral congenital cataract (UCC), and 132 eyes (90 children) with congenital glaucoma, aged 1 month to 15 years. Extended observation of anterior-posterior axis growth and refraction in eyes with artifakia showed a partial tendency to myopisation (3— 7%), which requires additional research of the pathogenetic process and should be taken into account when calculating the optical power of 1OL. The analysis of data on age-related growth of the anterio-posterior axis of eyes with congenital glaucoma showed the agreement with average figures for the developed and advanced stages of the condition. In contrast, terminal and advanced glaucoma (in children aged 2 to 3) the obtained data showed a reliable increase as compared to previously published values
Aim of research. To study the dynamics of the FBS of the eyes in children with congenital glaucoma by age. The studies were carried out in the clinic of TashPMI, on 132 eyes with congenital glaucoma. By age, patients were distributed according to the classification of E.S. Avetisova 2003. At the advanced stage of FBS, the eye exceeded the average statistical norm by 2.9 mm, 2.3 mm, 2.3 mm, at the advanced stage by 4.7 mm, 4.8 mm, 6.3 mm, and at the terminal stage by 7.5 mm, respectively, in each age group of eyes. An increase in the size of the anterior-posterior axis of the eye in congenital glaucoma depends not only on the violation of the hemo hydrodynamic processes of the eye with the accumulation of intraocular fluid, but also depends on the age-related dynamics of eye growth.
