“…A recent study by RB Mohammed et al, conducted among South Indian children who concluded that mean dental age showed significant underestimation of 0.7 ± 1.69 years and 0.11 ± 1.3 years in boys and girls respectively [26]. However a study conducted among North Indian population by Grover et al reported that the method overestimated age of girls and boys by 0.24 and 0.36 years respectively [20].…”

Age plays an important role in various fields such as forensic science, various social and legal settings and treatment planning in clinical dentistry. Children with undocumented birth date are vulnerable to violation of various child rights. This pilot study aimed to test the applicability of Willem's method of dental age assessment at the threshold of 14 years considering prohibition of employment of children. The sample consisted of 30 males and 30 females. The dental age estimation was performed by two blinded examiners using Willem's method. The accuracy of Willem's method of age assessment was measured by the difference between the chronological age and estimated dental age. It was seen that there was underestimation of age in both males and females. The difference in females and males were -0.29 years and -0.23 years respectively. The scores of dental maturation described by Willems may be suitable for South Indian children.

“…En cuanto a las investigaciones respecto a métodos de estimación de edad, el estudio realizado por Mohamed et al (11), fue llevado a cabo por el Departamento de Medicina y Radiología de la Escuela Dental de Visakhapatnam en la India (del mismo grupo étnico). Evaluaron la aplicabilidad de 4 métodos: Demirjian, Willems, Nolla y Haavikko adaptado para niños del sur de la India.…”

Objetivos: Comparar la edad cronológica y la edad dental empleando el Método de Demirjian en niños de 4 a 16 años de edad que acuden a un Centro Radiológico Privado, durante el año 2014 en Puebla, México. Material y Métodos: Diseño descriptivo, retrospectivo y analítico; en donde la muestra fue la misma que la población la cual consistió de 1125 radiografías panorámicas, tomadas durante el año 2014. Se realizó el cálculo de la edad dental en cada una de ellas, de acuerdo al método de Demirjian. Teniendo este dato se hizo un análisis compa- rativo con la edad cronológica tomada de la base de datos de las imágenes, utilizando la prueba de Wilcoxon. Resultados: En las125 Rx panorámicas se determinó la edad dental. Una vez hecho el comparativo con la edad cronológica los resultados mostraron que en el grupo etario de 14-14.99 años se presentó el mayor número de radiografías de acuerdo a la edad cronológica, siendo en su mayoría mujeres. Se comparó la edad dental con la edad cronológica, determinando por grupos de edades la significancia estadística. Al comparar la edad dental con la edad cronológica en el sexo femenino, únicamente en el grupo etario de 8-8.99 años no hubo diferencia estadísticamente significativa (p>0,05), mientras que para el sexo masculino fueron los grupos etarios de 4-4.99, 8-8.99 y 9-9.99. Conclusiones: La estimación de edad de acuerdo al Método de Demirjian en la población mexi- cana estudiada es adecuado únicamente en los grupos de edad de 8-8.99 para el sexo femenino y 4-4.99, 8-8.99, 9-9.99 para el sexo masculino, encontrando que en el resto de la muestra mexicana sobreestima la edad.

“…Disagreement was resolved by discussion among the review authors during the selection of articles. Finally, 12 relevant studies were retained for the qualitative synthesis and 10 for quantitative analysis or meta-analysis [6][7][8][9][10][11][12][13][14][15][16][17] . The process of study, screening and literature search are depicted in Figure 1.…”

“…Over the past few decades, numerous studies have been published using Nolla's method 4 for age assessment of sub-adult dentition [6][7][8][9][10][11][12][13][14][15][16][17] . So far, no meta-analysis of different studies has been published to estimate the reliability and accuracy of Nolla's method in evaluating age of sub adult individuals.…”

Nolla's radiographic method of dental age estimation for sub-adult individuals has been commonly used for forensic purposes. To identify the accuracy and credibility of this method, a review has been conducted for estimating the variations/discrepancies between actual chronological and estimated ages of sub-adults individuals calculated by applying Nolla's radiographic method in different population groups. The articles using Nolla's method of age estimation and those published between 2006 and 2016 were used after relevant searches in PubMed, EMBASE, SCOPUS, COCHRANE and Web of Science databases. Studies conducted with dental radiographs of healthy subjects between 3 and 18 years of age and those reporting mean differences between the estimated dental age (DA) and chronological age (CA) as a measure of variation were included in the review for meta-analysis. A total of 5813 subjects (2839 boys and 2974 girls) between the age of 3 and 18 years were examined in the study, which were chosen from a total of 87 peer-reviewed articles. Quantitative (10 studies) and qualitative (12 studies) analyses of the results revealed that dental age of most sub-adults was found under-estimated using this method based developmental stages of teeth. The underestimation varied from +0.26 to +1 years for males, and +0.051 to +1.15 for females; with an average mean of 0.35 years and 0.20 years for males and females, respectively. Thus, it can be concluded that Nolla's method of dental age estimation underestimates the age of an individual in almost all the studies reviewed here. It should be carefully applied for forensic cases requiring legal scrutiny by courts of law.
