ABSTRACT


Aim

The aim of this study is to determine the timing of primary teeth eruption in Spanish children, and to distinguish gender
and arch differences.

Methods

A cross-sectional study was performed on primary teeth eruption in a sample of
1,250 children (623 girls and 627 boys) from the Region of Madrid aged between 3 and 42 months. The clinical emergence of teeth was
taken to estimate the mean ages of primary teeth eruption. The t test was used to analyse gender and arch differences.

Results

The
process of primary dentition lasted 22.28 months, and statistically significant differences were found in the eruption of homologous
contralateral teeth. The first molars and maxillary lateral incisors erupted earlier in girls than in boys, with no statistically significant
chronological differences. The central incisors and second molars erupted first in the mandibular arch, while the lateral incisors, canines
and first molars erupted first in the maxilla. A greater chronological difference was found between the lateral incisors, which erupted
more than 8 months earlier in the maxilla than in the mandible. CONCLUSIONS: In the overall sample, the first tooth to erupt was the
lower right central incisor at 10.96 1.88 months, and the last was the upper left second molar, at 33.24 4.35 months,
symmetry was found in the eruption of the deciduous teeth. The greatest chronological difference was observed in the lateral incisors,
with the upper ones erupting more than 8 months before the lower ones. Although statistically significant gender differences were found,
they were considered clinically irrelevant.
