ABSTRACT
The aim of this study was to investigate the prevalence of supernumerary teeth in a Brazilian pediatric population. One examiner evaluated the presence of supernumerary teeth in panoramic radiographs of 1719 subjects (762 male and 957 female), with ages ranging from 4 to 14.5 years (mean 8.4 years old), from the archive of the Preventive Orthodontic Course of the Rehabilitation Hospital of Bauru, São Paulo. Supernumerary teeth were present in thirty subjects (1.7 percent, 16 males and 14 females). Difference between sexes was not statistically significant. Twenty-nine supernumerary teeth (96.7 percent) were located in the maxilla, and only 1 (3.3 percent) located in mandible. Seventeen supernumerary teeth (56.7 percent) located in maxilla were mesiodens. The early diagnosis of supernumerary teeth is essential to prevent malocclusion and malposition of permanent teeth demonstrating the importance of panoramic radiographs in their detection.
RESUMEN
El objetivo de este estudio fue investigar la prevalencia de dientes supernumerarios en una población pediátrica de Brasil. Un examinador evaluó la presencia de dientes supernumerarios en radiografías panorámicas de 1719 sujetos (762 hombres y 957 mujeres), con edades comprendidas entre 4 y 14,5 años (media 8,4 años de edad), del archivo del Curso de Ortodoncia Preventiva del Hospital de Rehabilitación de Bauru, São Paulo. Los dientes supernumerarios se presentaron en treinta sujetos (1,7 por ciento, 16 hombres y 14 mujeres). La diferencia entre sexos no fue estadísticamente significativa. Veintinueve dientes supernumerarios (96,7 por ciento) se ubicaron en el maxilar, y sólo 1 (3,3 por ciento) se ubicó en la mandíbula. Diecisiete dientes supernumerarios (56,7 por ciento) ubicados en el maxilar eran mesiodens. El diagnóstico precoz de los dientes supernumerarios es esencial para prevenir la maloclusión y malposición de los dientes permanentes, lo que demuestra la importancia de la radiografía panorámica en su detección.
