RESUMENObjetivoEl propósito de este estudio fue determinar la prevalencia y condición de los dientes supernumerarios no asociados a síndromes en el Departamento de Ortodoncia de la Universidad Latinoamericana, Campus Valle en México D.F.Material y métodosSe realizó un estudio retrospectivo utilizando 1,038 radiografías panorámicas de 622 mujeres y 416 hombres, con edades comprendidas entre los 9 y 57 años de edad en un periodo de 20 meses. Se contemplaron la edad y el sexo del paciente, la clasificación del diente supernumerario y la ubicación. Las variables de género, número y edad se resumieron con porcentajes y la media y desviación estándar respectivamente.ResultadosSe encontraron 40 dientes supernumerarios en 29 pacientes (2.8%); de éstos, 17 fueron hombres y 12 mujeres. En los hombres se encontró el 55% de dientes supernumerarios, mientras que en las mujeres el 45% del total. De acuerdo a su clasificación se observaron los siguientes porcentajes: mesiodens 35%, entre cónico 20% y tuberculado 15%, molares suplementarios 22.5%, premolares suplementarios 17.5%, caninos e incisivos laterales suplementarios 10% cada uno. Respecto a su ubicación no se encontró gran diferencia entre el maxilar y la mandíbula (p = 0.168).ConclusionesAl parecer, el mesiodens es el diente supernumerario que se presenta con mayor frecuencia, siendo el maxilar superior el más afectado en el sexo masculino; sin embargo, las mujeres presentaron mayor cantidad de dientes supernumerarios.ABSTRACTObjectiveThe aim of this study was to estimate the prevalence and conditions of supernumerary teeth not associated to syndromes in the University of Latin America Orthodontics Department Campus Valle in Mexico City.Material and methodsA retrospective study was made using 1,038 panoramic radiographs, 622 females and 416 males, ages between 9 and 57 years old in a period of time of 20 months. Considering age, sex, classification of the supernumerary tooth and location. The variables of gender, number, and age, were specified in rates as well as the mean, and standard deviation respectively.Results40 supernumerary teeth were found in 29 patients (2.8%), 17 in males, 12 in females. In accordance to their classification, the next rates were found: mesiodens 35%, conical 20% and tuberculated 15%, supplemental molars 22.5%, supplemental premolars 17.5%, supplemental cuspids and lateral incisors 10% each. With respect to their location, there is no statistically significant difference between maxilla and mandible (p= 0.168).ConclusionsIt seems that the mesiodens are the most frequent supernumerary teeth, being the Upper maxilla the most affected in males, although females had more supernumerary teeth.
