SAN MIGUEL PENTON, Armando et al. Permanent dentition emergence chronology in children from Santa Clara municipality: Part I. Rev Cubana Estomatol [online]. 2011, vol.48, n.3, pp. 208-218. ISSN 0034-7507.

A cross-sectional, descriptive and epidemiologic study was conducted of permanent dentition of children from Santa Clara municipality between 2005 and 2009. To determine the permanent dentition emergence chronology in children (boys and girls) from the Santa Clara municipality and to establish the differences in relation to values offered by other populations. The universe included 45 724 infants of both sexes aged between 4 and 14 with a sample of 1 769 subjects. Mean values were obtained establishing the chronology from the 50 percentile comparing the obtained eruption averages with that offered by other authors. The age of permanent teeth emergence was determined in study sample. There was a chronologic advance in: incisors, upper canines, first lower molars and second lower bicuspids, and retard for the second upper bicuspids and the canines in relation to authors selected for comparison. The emergence chronology achieved differs from the values offered by other populations. The great coincidence was in the case of Logan and Kronfeld values. The above chronology differs between sexes.
