description Objetive. To observe the types of soft facial profile according to the angles of facial convexity (FCA) and total facial convexity (TFCA), in addition to evaluating their relationship with the distal position of the primary second molars in children between 3 and 5 years. Methods. Twenty-eight out of 200 children with complete primary dentition were examined to determine the distal relation of primary second molars, and a digital photographic examination of their lateral profile was performed to evaluate the ACF and ACFT. With the Fisher's exact test, soft tissue profiles were compared according to age and gender, and with Student t test for a single sample, the angular averages were evaluated. Results. The mean of the FCA was 167.1 ° ± 5.1, and the TFCA was 145.8 ° ± 3.7. A high convexity of the FCA was observed in 21.4% of the children, medium in 60.7% and low in 17.9%. While in the TFCA it was divided into 17.9% with high convexity, 67.9% medium and 14.2% low. The average value of the FCA for the mesial step, flush terminal and distal step 169.2 ° ± 3.7, 168 ° ± 4.9 and 162.5 ° ± 4.8, while the average of the TFCA was 146.7 ° ± 4.4, 146.3 ° ± 3.6 and 143.5 ° ± 2.8 respectively. Conclusions. A significant relationship between the presence of a high convex profile and a distal step molar relationship was observed for the FCA, as well as a significant difference between the average of this angle in distal step compared to the reference average.

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.Universidad Nacional Mayor de San Marcos, Facultad de Odontología2019-09-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/odont/article/view/1670610.15381/os.v22i3.16706Odontología Sanmarquina; Vol. 22 No. 3 (2019); 173-179Odontología Sanmarquina; Vol. 22 Núm. 3 (2019); 173-1791609-86171560-9111reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/odont/article/view/16706/14266Derechos de autor 2019 Felipe Maldonado Araya, Mauricio Campos Pardo, Andrea García Prado, María Angélica Cereceda Mirandahttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/167062019-09-16T12:42:59Z
