Age and Sequence of Emergence of Permanent Teeth in a Population of Costa Rican Schoolchildren

Abstract

The aim of this study was to determine the average age and sequence of eruption of permanent dentition in the school population of the province of Cartago, Costa Rica. Methods: A cross-sectional observational study included children between the ages of 5 and 12 from public and private schools. Clinical examination was performed, and the presence or absence of permanent teeth recorded. Statistical analysis: An estimation of means of eruption was used through binary variables, building the probabilities of the presence of a dental piece through a logistic regression. Results: 833 children were examined: 433 (51.90%) girls and 400 (48.10%) boys. The permanent teeth erupt first in the female sex; however, this difference is not statistically significant. The maxilla eruption sequence for girls was 6-1-2-4-3-5-7 on both sides; for boys, the sequence of eruption was 6-1-2-4-5-3-7 for the right side and 6-1-2-4-3-5-7 for the left side. In the jaw, the sequence in boys was 6-1-2-3-4-5-7, and in girls, 1-6-2-3-4-5-7. Conclusions: For the first time, at the Central American Level, the pattern of permanent dentition eruption could be established. The age of permanent dental eruption does not vary according to sex in this population.

Influence of diet patterns on time of emergence of permanent teeth of children of Quetta, Pakistan

“…However, only two of them were statistically significant. This outcome is in agreement with some of the studies conducted in 19 Central America (Costa Rica), and 20 North Africa (Egypt). Furthermore, most of the studies performed in Asia permanent teeth.…”

Asociación entre estado nutricional y la cantidad de dientes permanentes en niños escolares en Costa Rica

“…El rango de edad se eligió así debido a que en esta población la edad promedio de la erupción del primer diente permanente es a los 6,20 años y la segunda molar permanente a los 12,33 años. 12 Los criterios de exclusión se aplicaron a la hora de hacer el examen clínico y consistieron en niños con malformaciones de esmalte o dentina, con tratamiento ortodóntico, con extracciones dentales previas o sujetos con condiciones que alteran la erupción dental tal como la displasia ectodérmica. No se excluyeron individuos por condición económica, etnia, religión o condición física o mental.…”

Only a few investigators have discussed the effect of nutrition on the time of eruption of permanent teeth.…”
