Study of Chilean Children’s Dental Maturation*

Abstract

In forensic science, determining a person's chronological age has become a challenge for researchers. Determining age using dental calcification is becoming increasingly important. The objective of this study is to estimate the dental age of the children's population in Region VIII, Chile. The sample was randomly taken from children under the care of the Faculty of Dentistry at the Universidad de Concepción in Chile. The study encompasses 159 children between 3 and 14 years of age. The dental age was determined following the Demirjian method. The Bland-Altman method was applied to establish the correlation. It was determined that the range between chronological and dental age is similar, and the degree of correlation between both ages is nearly perfect. In conclusion, the degree of correlation between the chronological and dental ages for each gender is also very good although it is slightly higher for females.

Dental and Chronological Age in Children Under Oncological Treatment

“…In a previous study, we showed that the range between chronological and dental age is similar and that the degree of correlation for each sex is also significant (8). In addition, other researchers have observed that skeletal maturation is associated with teeth calcification stages (11,12).…”

“…This method was initially based on a group of French Canadian children , but Flores et al. demonstrated that the Demirjian method is applicable to Chilean children.…”

“…A highly significant association between chronological and dental age in the entire group as measured by the Demirjian method was observed. This method was initially based on a group of French Canadian children (5), but Flores et al (8) demonstrated that the Demirjian method is applicable to Chilean children.…”

Dental age assessment in orthodontic patients with and without skeletal malocclusions

“…In archeology and forensic odontology, age estimation methods can aid to the age identification of a deceased child. They have also been proven valuable when birth data are lacking or doubted in the management of immigration to help to determine physiologic age (1, 2). Additionally, it is of particular interest to the pedodontist and orthodontist as information aids in diagnosis and treatment planning (2, 3).…”

Estimación de Edad Dentaria Utilizando el Método de Demirjian en Niños de 5 a 15 Años de Curicó, Chile

“…Se han realizado numerosos estudios en diferentes grupos étnicos, analizán-dose niños europeos, asiáticos y sudamericanos, entre otros. Se ha sugerido que puede haber diferentes patrones de maduración dental entre las distintas poblaciones, no sólo entre grupos poblacionales alrededor de todo el mundo, sino también entre individuos de diferentes ciudades o áreas geográficas dentro del mismo país (Cruz-Landeira et al, 2010;Eid et al, 2002;Lee et al, 2008;Liversidge et al, 1999;Moananui et al, 2008;Nyström et al, 2000;Nyström et al, 1988;Flores, et al, 2010;Teivens & Mörnstad, 2001). …”
