“…Bimaxillary protrusion is considered a common feature for the black individuals 4 , 5 and the real need for facial convexity reduction in this group is still object of investigation. In this regard, the current study was carried out to clarify the perception of the population of the city of Salvador about the facial profile attractiveness for a brown subject.…”

“… 10 Among the treatments available for reduction of face convexity, extraction of premolars followed by anterior teeth retraction produces a significant effect; 4 however, it is questionable whether the procedure is reasonable in brown and black patients, since dental protrusion may be considered a normal morphological feature in these groups. Moreover, available cephalometric analysis may not be completely suitable for employment in brown and black subject’s treatment planning, since the patterns are usually brought from white Caucasian samples 5 . Orthodontic planning should take great consideration of these features specially in regions with important racial diversity.…”

Introduction: The attractiveness and facial aesthetics are commonly defined by the media in modern society and the number of patients seeking for changes in the facial appearance is progressively increasing. Augmented face convexity is believed to be non aesthetic and among the treatments available for its correction, the extraction of premolars followed by anterior teeth retraction produces a significant effect. However, it is questionable whether the procedure is reasonable in brown and black patients, since dental protrusion is considered a common morphological feature in these groups. Methods: A photograph of a brown female subject was manipulated with image-editing program to generate a set of images with different degrees of labial retraction/protrusion. Two hundred individuals, randomly selected, were asked to rate each photograph and select which one showed the best aesthetic appearance. The survey was carried out in Salvador / Bahia (Brazil), which is a city with strong African slavery background and high proportion of brown and black population.Results:Regardless of color, sex or income, the interviewees chose primarily the straight facial profile and secondarily the slightly concave or convex as more pleasant for a brown female individual (p< 0.05). The moderate and extreme convexity had the lowest scores (p< 0.05). Conclusions: It is suggested that among the accessed population, straight and slightly convex or concave profiles were preferred for a brown subject and moderate or excessive facial protrusion were not well accepted. It is expected that these data can guide orthodontists about the need for extraction to reduce dental protrusion in brown patients.

RESUMEN Introducción: Inteligencia artificial (IA) es la automatización de actividades vinculadas con procesos de pensamiento humano. En ortodoncia se han desarrollado sistemas que asistidos por IA pueden tomar decisiones terapéuticas y realizar análisis. No existe un compendio actualizado sobre el uso de IA en ortodoncia. Objetivos: Describir los usos de IA en ortodoncia de acuerdo con la literatura actual. Metodología: Se realizó una revisión narrativa en las bases Medline y SciELO mediante la búsqueda: (orthodont*) AND (“machine learning” OR “deep learning” OR “artificial intelligence” OR “neural network”). Resultados: Se obtuvieron 19 artículos que mostraron que IA se ha desarrollado en cinco áreas: 1) Cefalometría asistida por IA, donde la localización de puntos y análisis cefalométricos mostraron una precisión igual a ortodoncistas. 2) Localización de dientes no erupcionados en CBCT, con resultados similares entre IA y ortodoncistas. 3) Determinación de edad y maduración ósea de forma más eficiente apoyada por IA, que por métodos convencionales, 4) Análisis facial, donde la IA permite una evaluación objetiva del atractivo facial, con aplicaciones en diagnóstico y planificación quirúrgica. 5) Decisiones terapéuticas con IA, para determinar la necesidad de exodoncias y dientes que serán extraídos. Discusión: La IA se está incorporando aceleradamente en ortodoncia, por lo que debe conocerse conceptos y posibilidades que brinda. Conclusiones: Un número creciente de artículos sobre usos de IA en ortodoncia muestran resultados similares con IA a los obtenidos por especialistas. Sin embargo, la evidencia aún es poca y principalmente experimental, por lo que la IA debiera usarse cautelosamente en ortodoncia.

“…The Center for the Study of Human Growth and Development, at the University of Michigan in 1974, for all indicators based on the study of 83 people aged from 6 to 16 years, were defined average standards for each child's age [18]. But it should be borne in mind that the understanding of true occlusion relates to the harmonious features of the person and takes into account the individual ethnic, age and sexual characteristics, which according to various studies vary considerably [1,4,12,19,20].…”

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.
