Abstract
BACKGROUND: Little information is available regarding the eruption chronology of Spanish children. Therefore, it is important to acquire accurate eruption parameters for the Spanish population. AIM: To establish the chronology of the permanent dentition. DESIGN: A cross-sectional study based on a sample of 1123 Spanish Caucasian children ranging from 5 to 15 years of age, from three different schools in Barcelona, Spain. RESULTS: The sample is representative of the Spanish population with regards to age, height and weight; and large enough to achieve the desired 95% confidence level. The results appear in the eruption tables included in the body of this paper CONCLUSIONS: In both boys and girls, the lower left central incisor is the first, and the upper right second molar is the last tooth to erupt. Mandibular teeth tend to erupt before the corresponding maxillary teeth; however there is no difference between the left and right sides of each arch. The results obtained are in agreement with similar studies performed in other groups of Caucasian children.
