Introduction:  in assessing children&#8217;s smile, a gingival smile is usually accepted as normal, but there is no scientific evidence to support this statement. The goal of this research project was to describe the structural characteristics of posed unforced smile in children with normal occlusion in deciduous and mixed dentition.  Methods:  a cross-sectional study in 122 children aged 3 to 12 years with normal occlusion. Each kid was recorded a video clip and taken a photogram in unforced posed smile, which was used to quantify and describe smile variables. These variables were compared by gender and dentition type: the quantitative variables were analyzed with one-way ANOVA test and Student&#8217;s t test, and the qualitative variables with Pearson&#8217;s chi-squared test, using a significance level of 0.05.  Results:  the soft tissues evaluated in smile showed significant differences between deciduous dentition / early mixed dentition and silent mixed dentition / late dentition. These values were lower in females. There was a prevalence of high smile in deciduous dentition and early mixed dentition, and medium smile in silent mixed dentition and late mixed dentition. 89.3% of children had a matching smile arch. The smile rate was proportional among the dentition stages evaluated and between males and females.  Conclusions:  the high smile is predominant among child patients in early deciduous dentition and mixed dentition, and gingival exposure reduces as kids grow.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN.  Introducción:  al valorar la sonrisa en niños se acepta como normal una sonrisa gingival, pero no se cuenta con evidencia científica que sustente esta afirmación. El objetivo de esta investigación fue describir las características estructurales de la sonrisa posada no forzada en niños con normoclusión, en dentición decidua y mixta.  Métodos:  estudio transversal realizado en 122 niños entre tres y 12 años con normoclusión. A cada uno se le realizó un video clip y se le extrajo un fotograma en sonrisa posada no forzada, sobre el cual se cuantificaron y describieron las variables de la sonrisa. Se compararon estas variables por género y tipo de dentición: las cuantitativas con la prueba ANOVA de una vía y t de Student y las cualitativas con el x2 de Pearson. Se asumió un nivel de significancia del 0,05.  Resultados:  los tejidos blandos evaluados en sonrisa presentaron diferencias significativas entre las denticiones decidua y mixta inicial, y las denticiones mixta silente y tardía; estas medidas fueron menores en mujeres. Hubo un predominio de sonrisa alta en dentición decidua y mixta inicial, y sonrisa media en dentición mixta silente y mixta tardía. El 89,3% de los niños presentaron arco de sonrisa coincidente. El índice de la sonrisa fue proporcional entre los estadios de dentición evaluados y entre hombres y mujeres.  Conclusiones:  se observó que la línea de sonrisa alta predominó en pacientes niños en dentición decidua y mixta inicial y que la exposición de encía se reduce conforme el niño crece.]]></p></abstract>
