Summary
Chronology and eruption sequence study results in the Iztapalapa delegation from México City are presented in comparison with the Hurme tables. The objective of this study was to identify the chronology and sequence of the permanent teeth eruption in a school population between six and twelve years old from 19 public elementary schools, located in the four educational regions in the Iztapalapa delegation, Mexico City. We carried out a cross-sectional, observational and descriptive study, with a convenience sample of 5915 students from 19 elementary public schools in the Iztapalapa delegation, Mexico City. The collection of information was performed from September 2012 to November 2013, the oral exam was done considering as an erupted tooth, when a part or the entire crown were found in the mouth. The information was collected in a special poll designed for this study, in this poll we recorded with the number one, if the tooth was erupted and with the number two if it was not found in the mouth. This information was captured in the SPSS software versión 15.0. When comparing the eruption from the students in Iztapalapa and the Hurme studies, in the upper quadrant, canines as well as the second premolars in both sexes erupted first in Iztapalapa. The rest of the teeth erupted first in the students from the Hurme studies. In the lower quadrant the only teeth that erupted first were second premolars, the rest of the teeth erupted first in the Hurme studies. The chronology of the eruption in Iztapalapa school was later regarding Hurme tables.
