“…For example, orthodontic treatment to reduce protruding incisors, can lead to lip changes that increase the relative prominence of the nose. [2,36] Mandibular surgery may also affect the relative prominence of the nose because of changes in the soft tissue chin and Holdaway [19] 1983 Caucasian 14-24 Lew et al [21] 1992 Chinese 6.00 Alcalde et al [22] 2000 Japanese 14.54 Basciftci et al [20] 2003 Turkish 18.74 Al-Gunaid et al [23] 2007 Yemeni males 16.70 Hameed et al [24] 2008 Pakistanis 19.36 Al-Azemi et al [25] 2008 Kuwaitis 14.25 Taki et al [26] 2009 Persian adults 16.72 Mehta et al [27] 2010 Indians 13.38 Hussein et al [28] 2011 Palestinians 19.24 Al-Barakati and Bindayel [29] 2012 Saudi Arabians 13.46 Present study 2014 Nigerians 3.49 lower lip.

“…Holdaway's analysis was chosen as it has been widely used in different studies to assess the soft tissue profiles of different populations. [19][20][21][22][23][24][25][26][27][28] Thus, providing a greater basis for comparing the findings from this study to that reported for other populations.…”

“…Holdaway's soft tissue analysis has been used in several studies to report the cephalometric soft tissue findings of different ethnicities, in addition to the comparison of these findings to established Holdaway norms. [19][20][21][22][23][24][25][26][27][28][29] This analysis consists of 13 measurements, one of which is the nose prominence. [19] In previous studies, [16][17][18] the authors had extensively studied the soft tissue profile of Nigerians using different soft tissue analyses, including Holdaway's analysis.…”

Objetivo. Evaluar los tipos de perfil facial blando mediante los ángulos de convexidad facial (ACF) y convexidad facial total (ACFT) y su relación con la posición distal de los segundos molares primarios en niños entre 3 y 5 años. Métodos. Estudio transversal en 28 niños chilenos con al menos un apellido de origen español y dentición primaria completa, quienes cumplían con los requisitos del estudio. Para evaluar el ACF y ACFT se tomó fotografía digital estandarizada del perfil lateral. Con la prueba exacta de Fisher se comparó los perfiles blandos según edad y género, y con t de Student para muestra única se evaluó los promedios angulares. Resultados. Para el ACF la media fue 167,1° ± 5,1, y para ACFT 145,8° ± 3,7. Se observó convexidad alta del ACF en 21,4% de los niños, media en 60,7% y baja en 17,9%; y para el ACFT en 17,9%, 67,9% y 14,2% respectivamente. El promedio del ACF para la relación molar escalón mesial, plano vertical y escalón distal fue de 169,2° ± 3.7, 168° ± 4,9 y 162,5°±4,8, mientras que para ACFT fue 146,7° ± 4,4, 146,3° ± 3,6 y 143,5° ± 2,8 respectivamente. Conclusiones. Se observó para ACF relación significativa entre la presencia de perfil convexo alto y escalón distal, además de diferencia significativa entre el promedio de este ángulo en escalón distal en comparación al promedio de referencia. El ACF puede ser indicador aceptable de escalón distal, sin embargo, no es certero al evaluar un plano vertical o escalón mesial.

“…But do there exist unified standards and standards for the planning of profile metric characteristics? With the development of science, more and more researches has been accumulated that proves the existence of statistically significant ethnic, sex [11,24], age and constitutional differences in facial characteristics [1,6,8,[13][14][15]30].…”

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.
