Debido a la naturaleza de las variables, se utilizó la prueba de Chi cuadrado. Se utilizó un nivel de significancia de 5% con un intervalo de confianza de 95%. Resultados: Los datos fueron analizados con el paquete estadístico SPSS versión 24.0. Material y métodos: Se realizó un estudio descriptivo y transversal en un total de 140 adolescentes con edades entre 10 y 16 años, que completaron una ficha de registro en donde se evaluó la preferencia, aceptabilidad, orden de preferencia y aceptabilidad al uso sobre seis diferentes diseños de aparatos fijos visualizados en un álbum de fotografías. Objetivo: Evaluar la preferencia y aceptabilidad sobre seis diferentes diseños de aparatos ortodónticos fijos en adolescentes peruanos de dos colegios de Lima. The methods used in this study may not be reliable for adolescent assessment of aesthetics. No difference was found in smile ratings or preferences between adolescents with hypodontia and those with no missing teeth. When forced to choose between the aesthetics of space opening or space closure, the majority of examiners chose space opening with tooth replacement.

Results suggest that although adolescents perceive a difference in the aesthetic result of space opening and space closure for missing lateral incisors, the impact on the smile attractiveness is not clinically significant. Care should be taken if findings are used to aid clinical decisions, as the validity of the main findings is questionable. Each examiner undertook two tests to assess the smile aesthetics of the images: (1) rating attractiveness using visual analogue scale (VAS) and (2) choice of preference between pairs of images.ĭifficulties experienced with image manipulation and poor intra-examiner reliability of the VAS make interpretation of the results challenging. A control group of subjects without tooth agenesis was recruited. Adolescent orthodontic patients with hypodontia were recruited to assess the aesthetics of the images. Standardized photographs of pre-orthodontic patients with missing lateral incisors were manipulated to produce images that represented space opening and tooth replacement in the lateral incisor space and space closure with canine substitution into the lateral incisor space. To establish whether adolescent orthodontic patients with hypodontia have a preference between the aesthetic outcomes of two treatment strategies for lateral incisor agenesis.
