Aesthetics is one of the key elements that accompanies modern medicine, in particular, dentistry. The need for treatment not only eliminates the symptoms of the disease but also leads to the restoration or improvement of the aesthetic appearance of the person, and especially the face, gave impetus to the development of new areas of science and technology. An important step in the implementation of such treatments is experimental research to identify the norm for certain categories of the population, primarily according to sex and ethnic group. The aim of the study was to establish the characteristics of cephalometric parameters in Ukrainian young men and young women with orthognathic occlusion, which usually do not change during surgical and orthodontic treatment, depending on sex and facial types. On the basis of the clinic "Vinintermed" teleroentgenography was performed using a dental cone-beam tomograph Veraviewepocs 3D Morita (Japan). Cephalometric examination of lateral teleroentgenograms in 46 young men (aged 17 to 21 years) and 72 young women (aged 16 to 20 years) with orthognathic occlusion was done. The type of face was determined according to the morphological index of Garson. The evaluation of parameters that usually do not change during surgical and orthodontic treatment was performed in the licensed package "Statistica 6.0" using non-parametric methods of evaluation of the results. The percentile ranges of cephalometric parameters, which usually do not change during surgical and orthodontic treatment depending on the facial types of Ukrainian young men and young women with orthognathic occlusion has been established. Pronounced manifestations of sexual dimorphism of cephalometric parameters, which usually do not change during surgical and orthodontic treatment (higher values in young men) are established only for most linear dimensions (values of distances NS, Ar-Go, N-Se, N-CC, P-PTV and S-Ar) in representatives of different types of faces. Both between young men and young women with different face types, there are almost no reliable or tendencies of differences in cephalometric parameters, which usually do not change during surgical and orthodontic treatment.

Numerous studies have shown that teleroentgenographic indicators differ in people of different races, ethnicities, different populations, inhabitants of different geographical areas and often differ from the values of such indicators described by the authors of classical methods of cephalometric analysis. The aim of the study was to establish teleroentgenographic parameters that can be most often corrected during orthodontic and surgical interventions and to determine their features in Ukrainian young men and young women with orthognathic occlusion depending on profiles and facial types according to Schwarz A. M. The results of studies of lateral teleroentgenogram of the head of 49 young men aged 17 to 21 years and 76 young women aged 16 to 20 years with a physiological bite as close as possible to orthognathic using dental cone-beam tomography Veraviewepocs 3D Morita (Japan) are presented in this work. The morphometric teleroentgenographic parameters of the upper and lower jaws and inter-jaw parameters, which can most often change during surgical, orthodontic, cosmetic interventions in groups of persons with different profiles or types of faces according to Schwarz A. M., were determined. All significant differences between groups of young men with different facial profiles and between groups of young women with different facial profiles are of the same type: in both young men and young women with the first type of face profile – angle B is greater than in representatives with the third profile type, and angle MM is greater than in representatives with the third and second profile types; both in young men and young women with a second face type profile – distance R.asc. larger than the representatives with the first profile type; in both young men and young women with the third face profile type, the angle F is larger than in the representatives with the first profile type, the angle I is larger than in the representatives with the first and second profiles type, and the distances L-Mand and R.asc. larger than the representatives with the first profile type; the angle T have greater values in young men or young women with the first profile type of the face than with the second and third profiles type and have greater values in the representatives with the second profile type than with the first type profile of the face. Another picture is observed in the analysis of indicators in young men and young women with different face types. Thus, in persons with the third type of face the distance Max is greater than in persons with the first type and with the second type of face; the angle F in young men or young women with the third type of face is greater than in representatives with the second and first types, and in representatives with the second type – greater than in young men or young women with the first type of face. Young men with the first type of face have higher values of angles G, B and T than young men with the third type and angle B than young men with the second type of face; in young men with the second type of face – greater values of angle I than in young men with the first type and angle B than in young men with the third type of face; young men with the third type of face have larger values of angle I and distance R.asc. than young men with the first type of face. In young women, only tendencies to higher values of I and T angles were recorded in persons with the third type of face than with the first type. The obtained results indicate the need to divide young men and young women into separate groups according to the profile and type of person for an individualized approach to the definition and analysis of teleroentgenographic indicators in the population of Ukraine.

In Ukrainian young men (n=49) or young women (n=76) with orthognathic occlusion with different face types, numerous reliable and tendencies of differences of cephalometric parameters by the Stainer method were established. Among the indicators belonging to the second group (indicators of the upper and lower jaws according to the Steiner method), significant differences were found only between young women with a very wide face and other types of faces. Among the indicators belonging to the third group (indicators by the Steiner method that characterize the position of each individual tooth relative to each other, cranial structures and soft tissue profile of the face), more pronounced differences are also found between young women with very wide faces and other facial types; among young men – with representatives with a wide face compared to the middle and narrow face types. Among the cephalometric parameters belonging to the second group of indicators, the expressed manifestations of sexual dimorphism of cephalometric parameters are established only for linear indicators; among the parameters belonging to the third group of indicators, the manifestations of sexual dimorphism are established for both linear and angular indicators.

The aim: Is development and analysis of regression models of teleroentgenographic indices according to Schwarz A. M., which can be adjusted during surgery depending on the parameters that usually do not change in Ukrainian young men and young women with with normal occlusion close to orthognathic occlusion and different facial types. Materials and methods: Teleroentgenographic indices were obtained using a dental cone-beam tomograph Veraviewepocs 3D Morita and studied in 49 young men and 76 young women with normal occlusion close to orthognathic. Persons were divided into groups with different face types according to the recommendations of Schwarz A. M. In the license package “Statistica 6.0”, regression models of teleroentgenographic indices were built according to Schwarz A. M. Results: For young men with orthognathic occlusion and with different types of faces according to Schwarz A. M. constructed 10 of 27 possible reliable regression models of the group of teleroentgenographic indicators, which can be corrected during surgical, orthopedic interventions in dentistry depending on the group of basic, invariable cephalometric indicators greater than 0.6 (R2 = from 0.609 to 0.996); and in young women with different face types, 8 of the 27 possible reliable regression models in which the coefficient of determination is greater than 0.6 (R2 = from 0.642 to 0.986). Conclusions: The developed regression models provide the most individualized approach in determining the method and scope of the required dental intervention.

Objective: The purpose of this study was to determine perceived and normative orthodontic treatment need of senior year dental students using the Index of Orthodontic Treatment Need (IOTN) and Dental Aesthetic Index (DAI). Materials and Methods: Ninety-nine senior year students of the Faculty of Dentistry, Obafemi Awolowo University Ile-Ife, Nigeria, participated. Normative assessment of occlusal characteristics was car¬ried out using IOTN and DAI while the Aesthetic Component (AC) scale of IOTN was used by the students to assess perceived need. Results: With the AC scale of IOTN, 6.1% of the students expressed “borderline need” and 2% “great need” for treatment, while normative need was 41.4% for “borderline need” and 11.1% for “great need”. The Dental Health Component found 37.4% and 24.2% in these categories, respectively. The DAI gave 26.3%, 13.1% and 15.1% in the elective treatment, highly desirable treatment and mandatory treatment categories respectively. No gender-dependent differences were found. Moderate correlation was observed between perceived and normative need (r=0.643), which was significant (p<0.001). Conclusions: Over half of the dental students had orthodontic treatment need with both indices. Normative and perceived treatment need differed significantly. The perception of treatment need is not only influenced by knowledge and severity of malocclusion, as psychosocial factors acting on individuals may be involved.

The widespread use of methods of cephalometric analysis in practical orthodontics requires the adaptation of normative indicators for members of the local ethnic group. It is also important to study the relationships between cranial and odontometric parameters to understand the effects of these components on each other. The aim of the study was to establish the peculiarities of correlations between the characteristics of basal cranial structures determined by Bjork and Jarabak methods with teleradiographic parameters of the upper and lower jaws and the location of teeth in Ukrainian young men and young women with orthognathic occlusion. Teleradiography was performed in the mode of cephalometric examination of 49 young men (aged 17 to 21 years) and 76 young women (aged 16 to 20 years) who had a physiological bite as close as possible to orthognathic. Cephalometric analysis according to modifications of Jarabak J. R. – Roth-Jarabak and Bjork A. – CFT-Bjork methods, performed using OnyxCeph³™ software, 3DPro version, Image Instruments GmbH, Germany (software license № URSQ-1799). All indicators were divided into three groups according to Dmitriev M. O. (2017): the first group included metric characteristics of the skull, which are used as basic indicators in the methods of cephalometric analysis; to the second group – dental-maxillary in which the skeleton has already been formed and which surgical methods can change the length, width, angles and positions of the upper and lower jaws; to the third group – indicators that actually characterize the position of each individual tooth relative to each other, cranial structures and the profile of the soft tissues of the face. Correlation assessment was performed in the license package "Statistica 6.0" using the non-parametric Spearman method. As a result of the conducted researches in Ukrainian young men and young women with orthognathic occlusion the peculiarities of multiple correlations of characteristics of basal cranial structures determined by CFT-Bjork and Roth-Jarabak methods with teleradiographic parameters of upper and lower jaws and tooth location were established. Both the CFT-Bjork method and the Roth-Jarabak method have more reliable correlations in both young men and young women between the first and second groups (23.3 % for young men and 50.0 % for young women for CFT-Bjork and 48.4 % for young men and 41.1% for young women according to Roth-Jarabak) than between the indicators of the first and third groups (respectively 12.8 % for young men and 7.7 % for young women for CFT-Bjork and 22.5 % for young men and 12.5 % for young women for Roth-Jarabak). The expressed manifestations of sexual dimorphism of the received correlations between the indicators defined by CFT-Bjork and Roth-Jarabak methods both on quantity and force, and in some cases on a direction of correlations are established.

Obtaining orthognathic occlusion in a patient as a result of treatment is a key goal of any orthodontist. However, the thorny path that both the patient and the doctor must go through involves painstaking work, which primarily begins with planning and choosing a method of orthodontic treatment, predicting and modeling its results. However, the latter is possible only if previously conducted research to determine the normative indicators for a population. The aim of the study was to construct and analyze regression models of teleradiographic parameters according to the Jarabak method in Ukrainian young men and young women with orthognathic occlusion. 49 young men and 76 young women with orthognathic occlusion underwent cephalometric analysis of lateral radiographs according to the modification of the method Jarabak J. R. – Roth-Jarabak, performed using the software OnyxCeph³™. All parameters according to the Jarabak method were divided into three groups: the first group included metric characteristics of the skull, which are used as baseline indicators; to the second group – dental-jaw in which the skeleton has already been formed and which surgical methods can change the length, width, angles and positions of the upper and lower jaws; to the third group – indicators that characterize the position of each individual tooth relative to each other, cranial structures and the profile of the soft tissues of the face. Construction of regression models of teleradiographic indicators by the Jarabak method was performed in the licensed package “Statistica 6.0” using step-by-step regression analysis. When modeling teleradiographic parameters according to the Jarabak method, which were included in the second group, depending on the indicators of the first group in young men with orthognathic occlusion, 8 out of 19 possible reliable regression models with a coefficient of determination greater than 0.5 (R2= from 0.589 to 0.950) were constructed. The constructed equations most often include the value of the angle N-S-Ar and the distances Ar-Go and N-S. In young women with orthognathic occlusion, 6 reliable regression models of the second group were constructed depending on the indicators of the first group (R2= from 0.609 to 0.971). The constructed equations most often include the value of the distances Ar-Go, S-Ar, N-S and the angle N-S-Ar. When modeling teleradiographic indicators included in the third group, depending on the indicators of the first and second groups in young men, 5 out of 8 possible reliable regression models with a coefficient of determination greater than 0.5 (R2= from 0.658 to 0.751) were constructed. The constructed equations most often include the values of the angles N-A-Pog, N-Go-Gn, S-N-B and A-N-B. In young women with orthognathic occlusion, 6 reliable regression models of the third group were constructed depending on the indicators of the first and second groups (R2= from 0.509 to 0.772). The constructed regression equations most often include the value of the angles N-A-Pog, A-N-B, S-Ar-Go, S-N-A and the ratio Go_Me:N-S. The obtained models will allow orthodontists to automatically calculate the required cephalometric parameters.

Using Anthony Trollope’s character Tom Tringle ofAyala’s Angel, I argue that in his portrayal of the hobbledehoy, Trollope is imposing on Victorian boys and young men a code of behavior every bit as restrictive and every bit as unnatural as the “suffer and be still” doctrine imposed on girls and young women. Using critical tools from the fields of Masculinity Studies and studies of literary character, I discuss Trollope’s portrayal of Tom Tringle as emblematic of the restrictions Victorian gender ideology placed on women. What emerges is a new dimension to Victorian gender studies. The admonition addressed to Victorian women of all ages and classes that they should “suffer and be still” in the face of any adversity is well known, and is often accompanied by the assumption that no similar restriction is placed on boys and men. In the world of Anthony Trollope’s novels, however, unlike that of many other Victorian novelists, women seldom need much taming, as obedience is a strong character trait in the majority of his heroines. His young men, on the other hand, tend to be far less morally evolved, and in Trollope’s love plots, if anyone has to undergo profound changes of character before being fit for marriage, it is usually the man. I argue that Trollope’s stern but gentle treatment of the misfit Tom provides further answers to the often debated question of Trollopes relative conservatism.

For a successful orthodontic treatment, it is crucial to examine the patient in both frontal and lateral views. Evaluation of the skeletal pattern and softs tissues including nasolabial angle, anteroposterior lip position, labiomental angle, and Lip-chin-submental plane angle must all be considered. Facial profile greatly affects the aesthetic appearance of the patients, however, not every person has the same aesthetic perception. This review aims to point out the indicators of facial profile and the perception of facial profile attractiveness among the different populations. Many studies have evaluated the preferences of facial profile, some of them agreed as a straight profile with normally positioned lips was the most favored, but some differences were noted between orthodontists and laypeople in the perception of the facial profile. Laypeople found a slightly retruded mandible or protruded mandible was found aesthetically pleasing for some populations. Therefore, it is important to involve the patient in treatment planning and decision-making.

The article discusses the problem of defects in the front layer of brickwork of multilayer walls. At many facilities constructed using the technology of laminated masonry with brick facing, after several years of operation, defects such as vertical cracks in the masonry face layer and destruction of the bricks of the face layer begin to appear. These defects violate the aesthetic appearance of the building, reduce the thermal characteristics of the external walls, and, in some cases, can lead to the collapse of certain sections of the brick cladding layer. This problem is considered on the example of a 10-storey residential building with external multilayer walls, located in Perm. The building was commissioned in 2005, but already in 2010, many defects of the front layer of masonry were discovered. The article provides data obtained during surveys carried out in 2010 and 2019. The main defects of the external masonry verst are described, among which one can distinguish the destruction of the masonry face layer, vertical cracks, the absence of stitching along the supporting corner of the masonry, and the absence of expansion joints. The main causes of damage are associated with numerous deviations from the project. The results of calculating the outer verst of brickwork for eccentric compression are presented. As measures aimed at eliminating defects, the article describes possible methods of repairing the face masonry: the installation of vertical and horizontal expansion joints, longitudinal reinforcement and anchoring with BIT rods to prevent the development of vertical cracks and destruction of the masonry.
