Prevalence of malocclusions at the Orthodontics Department of the Graduate School, National School of Dentistry, National University of Mexico (UNAM)

Abstract

At the Graduate and Research School of the National School of Dentistry, National University of Mexico (UNAM) we developed several analytic and descriptive methods. A statistical study of skeletal classifi cation was undertaken with a sample of 428 patients subjected to orthodontic treatment. Age range of selected patients was 8-40 years. Data were collected according to gender, age and skeletal malocclusion in order to assess the epidemiological panorama. After statistical analysis, it was found among other data, that 53.3% of the sample was in skeletal class I, 64.7% were female and 52.08% was found to be in the 13 to 19 year age range
