Cronología y secuencia de erupción de los dientes temporales en una muestra infantil de la Comunidad de Madrid

Abstract

The eruption of temporary teeth has been subject of study in many populations; however, there are few that hove been conducted on the Spanish population. Objective: Determine the chronology and the sequence of eruption of the deciduous teeth in a sampling of children from the Region of Madrid. Material and Method: The sampling far this cross-sectional study was composed of 120 children, 62 mole and 58 females, between the ages of 5 and 40 months, which were sampled in different childcare centres of the Region of Madrid. Results: In general, the teeth of the upper arcade erupted before those of the lower arcade, except far the lower central incisors and of the lower left lateral incisor. In the case of the second molar, the average ages of emergence in both arcades were very similar. In the boys, the maxillary teeth erupted before the mandibular teeth, with the opposite occurring in the girls. In addition, an earlier emergence was observed in the males, with them presenting, however, a longer eruptive process. Conclusions: In the general sample, the first tooth to erupt was the lower left central incisor and the last was the lower right second molar. No differences were found in the eruption of the contralateral counterpart teeth.
