A descriptive cross-sectional study of 12-14 years-old adolescents from the health care area cared for by "Ormani Arenado" teaching dental clinic was carried out from July 2001 to July 2003, with the objective of describing the behavior of Rickett´s lateral analysis cephalometric standards. The universe of study was composed by 1 683 children studying in elementary and junior high schools of the said health care area, from whom a sample of 50 children (21 males and 29 females) with normal occlusion and no history of prior orthodontic treatment was taken by a feasibility method. The children under study were examined on the basis of the following variables: age, sex, Rickett´s lateral cephalogram measures and facial biotype. The statistical analysis was based on frequency distribution tables, central tendency stadigraph, dispersion tables and Pearson´s correlation coefficient. It was found that the behavior of jaw development matched with Rickett´s standards in 12 y and 14 y age groups whereas the 13-y age group showed mandible retrognathism. Maxillary protrusion, mesogression, vestibuloversion of incisors and lip protrusion were marked characteristics observed in the studied samples. There was high correlation among the variables determining the facial biotype. The mesofacial pattern followed by the dolichofacial pattern prevailed in biotypological distribution. It was concluded that some variations were observed in our population in comparison with Rickett´s lateral cephalogram measures that represent the international standard.
