According to many numerical literary sources, the modern direction of provision of dental care involves an individual approach to the patient, in particular, based on his gender, age and nationality. This calls for the creation of its own regulatory bases for the population of different countries and ethnic groups, taking into account all possible criteria. The purpose of the study is to establish and analyze the cephalometric parameters by the method of E.P. Harvold in young men and women of Podillia region of Ukraine with orthognathic bite. Primary lateral teleroentgenograms of 38 young men and 55 women with normal occlusion close to orthognathic bite, obtained using the Veraviewepocs 3D device, Morita (Japan), were taken from the data bank of the research center of the National Pirogov Memorial Medical University, Vinnytsya. Cephalometric measurements were performed according to the recommendations of E.P. Harvold. Statistical processing of the obtained results was carried out in the license package "Statistica 6.0" using nonparametric methods of estimating the results. When comparing teleroentgenographic indices between boys and girls of the Podillia region of Ukraine with orthognathic occlusion, significantly higher values of the length of the upper and lower jaw, lower facial height and interjaw differences in young men were established, and Ap1uAp1l-DOP angle was significantly higher in young women. When comparing these data with the results obtained by E.P. Harvold, the boys and girls of the Podillia region of Ukraine with orthognathic bite have significantly lower values of the length of the upper and lower jaw and lower facial height. In addition, Ukrainian young women have significantly higher values of the Ap1uAp1l-DOP angle and a tendency to lower interjaw differences, while in young men, the tendency towards higher values of the cross-sectional angle than the value of these parameters obtained by E. Harvold is established. The results of the study confirm the need to create a normative basis for teleroentgenographic indices by the method of E.P. Harvold for the population of different regions of Ukraine, taking into account both sexual and age affiliation.

It is proved that in the analysis of lateral teleroentgenograms according to different methods distances and angles have their normative indices which differ for persons of different ethnic, gender and age belongings. Therefore, for a full use in the orthodontics R.M. Ricketts method, similar studies are needed in Ukraine. The purpose of the work – in young men and women  with normal occlusion close to the orthognathic bite and harmonious face construct and analyze the regression models of teleroentgenographic indicators used in the method of R. M. Ricketts. Primary lateral teleroentgenograms of 38 young men (aged 17-21 years) and 55 young women (aged from 16 to 20 years) with normal occlusion close to orthognathic bite and harmonic face, obtained from the Veraviewepocs 3D device, Morita (Japan), taken from the bank data of research center of National Pirogov Memorial Medical University, Vinnytsya. Cephalometric measurements were performed according to the recommendations of R. M. Ricketts. All indicators were divided into three groups: 1 - metric characteristics of the skull, which usually do not change during surgical and orthodontic treatment; 2 – tooth-jaw indicators, the definition of which most often guided by performing orthodontic manipulations of patients in children and adolescents, as well as those with already formed bone skeleton when orthodontic surgery can change the width, length, angles and position of the bones of the upper and lower jaws; 3 - indicators that characterize the position of each individual tooth relative to each other, to the bony cranial structures and face profile. The regression models of individual teleroentgenographic indicators used in the R.M. Ricketts methodology are constructed using the “Statistica 6.0” licensing package. Constructed all 2 reliable models of the indicators included in the second group (distance Go-CF and Xi-Pm), depending on the indicators of the first group (in young men R2 = 0.884 and 0.928, and in young women - 0.735 and 0.719); as well as in young men, 7 out of 8 possible reliable models (R2 = from 0.568 to 0.887) of the indicators included in the third group (the magnitude of the distances 6u-6l, Overjet, Overbite, 6u-PTV, 1l-APog, 1u-APog and Xi-OcP ) depending on the indicators of the first and second groups; and only 5 models for young women (6u-PTV, 1l-APog, 1u-APog and Xi-OcP distances, and the magnitude of the Max1-APog angle). In the analysis of entering into the regression models of the relevant predictors, it was found that in young men, among the teleroentgenographic indicators of the first group included in the two models of the second group, is the distance P-PTV, and in young women the front length of the base of the skull N-CC and the back of the skull base Ar- Pt It was also found that among young men among the teleroentgenographic indicators of the first and second groups, which were included in the models of the third group, the most frequent is the value of the distance B-Pog (11.1%); while in young women - distance B-Pog (15.6%) and an angle DC-Xi-PM (9.4%).

The family character of atopic conditions, confirmed by many studies, has become the basis for the use of the method of dermatoglyphics to clarify the genetic nature of the “atopic march”. The purpose of the study was to identify differences in the features of palmar dermatoglyphics between patients with atopic dermatitis, allergic rhinitis and bronchial asthma. Primary indexes of palmar dermatoglyphics of young men and young women patients with atopic dermatitis, allergic rhinitis and bronchial asthma were taken from the data bank of the research center of National Pirogov Memorial Medical University, Vinnytsya. According to the method of Cummins H. and Midlo Ch. dermatoglyphic study of 320 young men and young women with allergic rhinitis (n = 69), bronchial asthma (n = 108) and atopic dermatitis (n = 143) was performed. Quantitative indices of palmar dermatoglyphics were subject to analysis. The results obtained were processed using the Statistica 6.1 license package using non-parametric methods. It is established that the differences of quantitative indices of palmar dermatoglyphics between young men / young women with atopic dermatitis and allergic rhinitis cover 50.0% / 66.67%; among patients with atopic dermatitis and bronchial asthma – 38.89% / 33.33%; among patients with allergic rhinitis and bronchial asthma – 22.22% / 55.56% respectively. Thus, in young men, the marker potential for signs of palmar dermatoglyphics in the prognosis for the development of bronchial asthma in the presence of allergic rhinitis (22.22%) or atopic dermatitis (38.89%) are insignificant compared with the prognosis for the development of allergic rhinitis in the presence of atopic dermatitis (50.0%). In young women, the marker features of palmar dermatoglyphics in the prognosis for the development of bronchial asthma in the presence of atopic dermatitis are insignificant (33.33%) compared with the prognosis for the development of bronchial asthma in the presence of allergic rhinitis (55.56%) and the prognosis for the development of allergic rhinitis (66.67%).

The difference in the characteristics of craniofacial structures in different races and ethnicities established in many studies requires the creation of a normative basis for teleroentgenographic indices and indices characteristic for a particular ethnic group. The purpose of the work is to set the cephalometric parameters by W. Downs for young men and women from Podillya region of Ukraine with orthognathic bite and compare the results with the data proposed by the author of the technique. With the device Veraviewepocs 3D device, Morita (Japan), 38 young men (17 to 21 years of age) and 55 young women (aged from 16 to 20 years) with orthognathic bite (normal occlusion close to orthognathic bite) received and analyzed lateral teleroentgenograms. Cephalometric points and measurements were performed in accordance with the recommendations of W. Downs (1948). Anatomical points were determined taking into account recommendations A.E. Athanasiou (1997), S.I. Doroshenko and Y.A. Kulginsky (2007). The statistical processing of the obtained results was carried out in the licensed package “Statistica 6.0” using nonparametric methods for evaluating the obtained results. As a result of the research, virtually no sex differences in cephalometric parameters by W. Downs between adolescents from Podillya with orthognathic bite were found. When comparing the cephalometric parameters obtained by W. Downs from similar figures obtained in Ukrainian young men and women with orthognathic bite, regardless of gender, established significantly lower values of Cant Occlusal Plane (angle POr-DOP) and angle II, as well as significantly higher values were established for angle 1l-DOP, angle 1l-MeGo and distance 1u-APog in Ukrainian young men and women of Podillya. The obtained results indicate the need to create a normative base for cephalometric standards by W. Downs for the population of different regions of Ukraine, taking into account gender and age belonging.

In spite of the existence of numerous developed methods of cephalometric analysis, which should help to choose the right direction of orthodontic treatment, usually the doctor has to act intuitively, based on his experience, because their development didn’t take into account numerous factors (ethnicity, age, gender, etc.). Improving these techniques, considering the above-mentioned factors, would significantly increase their effectiveness, and hence the quality of providing dental care to the population. The purpose of the work is to construct and analyze a regression model of teleroentgenographic indicators used in the method of C. J. Burstone in young men and women with normal occlusion close to orthognathic bite and harmonic face. Primary side teleroentgenograms of 38 young men (aged 17-21 years) and 55 young women (aged 16-20 years) with normal occlusion close to orthognathic bite and harmonic face, obtained from the Veraviewepocs 3D device, Morita (Japan), taken from the bank data of research center of National Pirogov Memorial Medical University, Vinnytsya. Cephalometric measurements were performed according to the recommendations of C. J. Burstone. All indicators were divided into three groups: 1 - metric characteristics of the skull, which usually do not change during surgical and orthodontic treatment; 2 - indicators of the tooth-jaw system, the definitions of which most often need to be guided by the orthodontic treatment of growing patients and orthodontic surgery, which allows people with already formed bone skeleton to change the width, length, angles and position of the bones of the upper and lower jaws; 3 - indicators that actually characterize the position of each individual tooth relative to each other, to the bony cranial structures and face profile. Regression models of individual teleroentgenographic indicators used in the method of C. J. Burstone, built using the licensed package “Statistica 6.0”. Constructed all 6 reliable models of indicators included in the second group (anterior lower facial height ANS-Gn/Me, maxillary length ANS-PNS, ramus length Ar-Go, mandibular length Go-Pog, anterior upper facial height N-ANS and posterior upper facial height PNS-N) depending on the indicators of the first group (posterior section of cranial base Ar-Pt, anterior skull base length N-CC, angle of the cranial tilt POr-NBa, anterior section of cranial base Pt-N and distance P-PTV); as well as all 7 reliable models of indicators included in the third group (distances 1u-NF, 1l-MP, 6u-NF, 6l-MP and angles OP-HP, Max1-NF/Max1-SpP, Mand1-Mp/Mand1-MeGo) depending on the indicators of the first and second (distance A-B, A-NPog, Gо-CF, Max-Mand, N-A, N-B, N-Pog and Xi-Pm and angles MeGo-NPog, MP-HP, NAPog, N-ANS-Pog, N-CF-A, NPog-POr, POr-CFXi і POr-ANSPNS) groups. It was established that in young men the model of telerentgenographic indices included in the second group depending on the indicators of the first group and included in the third group, depending on the indicators of the first and second groups, have a higher determination coefficient than in young women (R2 from 0.806 to 0.918 in young men and from 0.510 to 0.768 for young women, and from 0.750 to 0.993 for young men and from 0.510 to 0.986 for young women). In the analysis of entering into the regression models of the relevant predictors found that in young men among the teleroentgenographic indicators of the first group included in the models of indicators of the second group most often included - distances P-PTV (33.3%), Pt-N and N-CC (by 25.0%); and in young women– distances N-CC (38.5%) and P-PTV (30.8%). It was also found that among young men among the teleroentgenographic indicators of the first and second groups that were included in the models of the third group of indicators most often included - distance ANS-Gn/Me (12.8%), the magnitude of the angles NAPog, POr-CFXi and POr-ANSPNS (by 9.4%); and in young women– distance ANS-Gn/Me (13.2%), distances А-В and PNS-N and the magnitude of the angle NAPog (by 7.9%).

The analysis of scientific literature points to significant ethnic, racial, age and sexualdifferences in cephalometric indices obtained by the method of C. J. Burstone, whichnecessitates conducting similar cephalometric studies among different age and sexgroups of the population of Ukraine with physiological bite. The purpose of the study isto establish and analyze the cephalometric parameters by the method of C. J. Burstonein boys and girls of the Podillia region of Ukraine with orthognathic bite. Primary lateralteleroentgenograms of 38 boys and 55 girls with normal occlusion close to orthognathicbite, obtained using the Veraviewepocs 3D device, Morita (Japan), were taken fromthe data bank of the research center of the National Pirogov Memorial MedicalUniversity, Vinnytsya. Cephalometric measurements were performed according to therecommendations of C. J. Burstone. The statistical processing of the obtained resultswas carried out in the licensed package "Statistica 6.0" using nonparametric methodsfor evaluating the obtained results. When comparing the cephalometric parametersused in the analysis of C. J. Burstone between boys and girls with orthognathic bite inboys, the values of the following distances are significantly higher: Ar-Pt (PosteriorSection of Cranial Base), Pt-N (Anterior Section of Cranial Base), N-ANS (AnteriorUpper Facial Height), ANS-Gn (Anterior Lower Facial Height), PNS-N (Posterior UpperFacial Height), 1l-MP (Distance of Incisal Edge of 1L to Palatal Plane), 6u-NF (Distanceof Mesial Cusp of 6u to Palatal Plane), 6l-MP (Distance of Mesial Cusp of 6l toMandibular Plane), ANS-PNS (Maxillary Length), Ar-Go (Ramus Length), Go-Pog(Mandibular Length), B-Pog (distance from point Pog to point B, parallel to mandibularplane) and A-B (Distance of A to B on Occl. Plane); and in girls - only angle OP-HP(Angle of Occl. to Horizontal Plane). More than half of the cephalometric parametersobtained in the boys and girls of Podillia with orthognathic bite have reliable or tendencydifferences with the magnitude of the parameters given by C. J. Burstone, whichconfirms the need to establish their regional standards for correct use in Ukraine.

Customization of mental health therapies needs to consider the differences in degree of brain maturity between young (18–29 years) and mature (30 years or older) adults as well as brain morphology among men and women. The aim of this study was to identify the significant dietary and lifestyle contributors to mental distress in these sub-populations. Independent repeated cross-sectional sampling was performed for over a 5-year period (2014–2019) to collect data from different populations at different time-points and seasons. A backward stepwise regression analysis was used on 2628 records. Mental distress in young women was associated with high consumption of caffeine and fast-food, and it was negatively correlated with moderate-high levels of exercise as well as frequent breakfast consumption. Mature women shared several common factors with young women; however, high fruit consumption was negatively associated with mental distress. For young men, high exercise, moderate consumption of dairy, and moderate-high intake of meat were negatively associated with mental distress. In addition, high fast-food and caffeine consumption were positively associated with mental distress in young men. For mature men, strong negative associations between higher education, moderate intake of nuts and mental distress surfaced. Our results support the need to customize dietary and lifestyle recommendations to improve mental wellbeing.

Modern dentistry requires the definition of individualized values of teleroentgenographic indicators. To solve such problems, methods of regression and correlation analysis are increasingly used, which help to establish not only the existence of various relationships between the anatomical structures of the head and the parameters of the dento-jaw system, but also allow more accurately predict the change in the contour of soft facial tissue in response to orthodontic treatment. The purpose of the study is to develop mathematical models for the determination of individual teleroentgenographic characteristics of the facial soft tissues by studying the cephalometric indices of young men and women of Ukraine with normal occlusion and balanced faces and conducting a direct stepwise regression analysis. With the use of Veraviewepocs 3D device, Morita (Japan) from 38 young men (17 to 21 years of age) and 55 young women (aged from 16 to 20 years) with occlusal close to the orthognathic bite and balanced faces received side teleroentgenograms. The cephalometric analysis was performed using OnyxCeph³™ licensed software. Cephalometric points and measurements were made according to the recommendations of Downs W. B., Holdway R. A., McNamara J., Schwarz A. M., Schmuth G. P. F., Steiner C. C. and Tweed C. H. With the help of direct stepwise regression analysis, in the licensed package “Statistica 6.0”, regression models of individual teleroentgenographic characteristics of the profile of soft facial tissues were constructed. In young men with normal occlusion close to the orthognathic bite of 19 possible models, 11 were constructed with a determination coefficient from 0.638 to 0.930, and in young women – 12 models with a determination coefficient from 0.541 to 0.927. The conducted analysis of models showed that in young men most often the regression equations included – angle N_POG, parameters of which indicate a linear interjaw relation in the anterior-posterior direction (14.0%); angle GL_SNPOG, or index of convexity of the soft tissue profile (8.8%); MAX maxillary length (7.0%), and GL_SN_S index, which defines vertical correlations in the facial profile (5.3%). The young women most often models included – the angle N_POG (12.5%); angle GL_SNPOG (7.5%); soft tissue front angle P_OR_N (6.25%); the reference angle ML_NL and the profile angle T (by 5.0%); the angle AB_NPOG, the angle NBA_PTGN, which defines the direction of development of the mandible and the distance PN_A (3.75%). Thus, in the work with the help of the method of stepwise regression with inclusion, among Ukrainians of adolescence age, based on the characteristics of teleroentgenographic indicators, reliable models of individual teleroentgenographic characteristics of the profile of soft facial tissues were developed and analyzed.

The lawfulness of the application of the method of dermatoglyphics in the study of atopic diseases is ensured by the polygenic inheritance of signs of dermatoglyphics, on the one hand, and the pathogenetic heterogeneity of these diseases, on the other hand, as well as high informative ability of signs of dermatoglyphics as markers of diseases of hereditary and multifactorial nature. The purpose of the study is to detect differences in qualitative signs of digital dermatoglyphics between patients with atopic dermatitis, allergic rhinitis and bronchial asthma. Primary indicators of digital dermatoglyphics of sick young men and young women of the Podillia region are taken from the data bank of the research center of the National Pirogov Memorial Medical University, Vinnytsya and were used in previous studies when compared with the practically healthy population of this region. Imprints were obtained by the method of “printing ink” by Gladkova T. D. By the method of Cummins H. and Midlo Ch. a dermatological study was performed for 320 young men and young women with allergic rhinitis (n=69), bronchial asthma (n=108) and atopic dermatitis (n=143). The frequency and location of 8 types of finger patterns were subject to analysis. Statistical processing of the obtained results was carried out in the package “Statistica 6.1” using nonparametric methods. The reliability of the difference in values between independent qualitative values was determined by the formula of Weber E. (1961). The specificity of the digital typology of atopic diseases is established, which is based on the differences in the frequency and location of the whorl, central pocket and arches between the young men, except those indicated - a random pattern between young women, patients with atopic dermatitis, bronchial asthma, allergic rhinitis. Additionally, when comparing young men, patients with allergic rhinitis with patients with bronchial asthma and atopic dermatitis - ulnar loop; for bronchial asthma with patients with allergic rhinitis and atopic dermatitis - lateral pocket loop (in young men) and ulnar, lateral pocket and double loops (in young women); when comparing young men, patients with atopic dermatitis with patients with bronchial asthma, and allergic rhinitis - a random pattern.

Annotation. The problem of causation in the formation of eczema in terms of psychosomatic relationship is currently relevant and virtually unresolved. The application of the complex principle of research determines a multifaceted assessment of the psychological state of the personality of patients with eczema and the possibility of its optimal correction. The aim of the study was to study the differences between the indicators of the leading typological characteristics of temperament and psychodynamic features of personality between healthy and/or eczema patients depending on the severity of dermatosis. Men aged 22 to 35 years, with a diagnosis of true and microbial eczema, were evaluated for the leading typological characteristics of temperament according to the Eysenck questionnaire and psychodynamic personality traits according to the Spielberger-Khanin questionnaire. As a control from the data bank of the research center of National Pirogov Memorial Medical University, Vinnytsya indicators of the level of subjective control of 82 practically healthy men of the same age group were selected. Statistical processing of the results was performed in the license package “Statistica 5.5” using non-parametric evaluation methods. In general, it was found that among patients with eczema 5.6 % are introverts, potential introverts – 12.3 %, ambiverts – 44.6 %, potential extroverts – 29.0 % and extroverts – 8.5 %. Compared with healthy individuals, the percentage of patients with various forms and severity of eczema is higher due to subjects with low (all groups of patients) and potentially low levels of neuroticism (true eczema of mild course), low situational (true eczema of mild course eczema and microbial eczema of severe course) and personal (truth of severe eczema) anxiety, and lover – due to patients with potentially high levels of neuroticism (truth of severe eczema), moderate (severe microbial eczema) and high (truth of eczema mild) level and situation level of personal anxiety (the truth of mild eczema). Patients with severe disease are characterized by a higher level of neuroticism (true eczema) and a higher level of personal anxiety (microbial eczema) compared to patients with mild disease. Patients with severe microbial eczema have a higher level of situational anxiety compared to patients with true eczema of similar severity. Thus, psychodiagnostics, which is based solely on patients' self-description of their behavior, emotional and volitional state, leads to inconsistency, subjectivity, uninformativeness of the results of the study and does not reveal the dynamics of the disease or treatment features.
