“…In considering the total number of individuals, age calculated by both methods was underestimated; however, when assessing a subsample of the group up to 15 years of age using the 1.25 to 3.18 years ratio CA-DA difference found in older groups, there was an overestimation of age calculated by DEM 11 in both sexes, as reported in previous studies 2, 5, 7, 13, 15-17, 19, 20 using the revised version of the method. The values of the CA-DA difference in this study are higher than those observed in Korean, 13 Iranian, 5 and Tunisian 15 males, lower than those reported in Australian, 14 Spanish, 2 Chinese, 20 French, 7 Turk, 16 and Yugoslav 19 males, as well as in Iranian 5 and Tunisian females, 15 and similar to those found by Abesi et al 18 in another sample of Iranian origin. Table 4 shows the difference in values between CA and estimated DA found in the aforementioned studies, enabling a comparison with those obtained in the present study.…”

“…15 Regarding the method of Demirjian et al, 1,11 a consistent overestimation of age (CA-DA difference) has been found, with average values of -0.60 years in males (0.23 to -3.04) and -0.65 years in females (0.10 to -2.82 years), when used in individuals with ethnic and socioeconomic characteristics that differ to those of the sample used to standardize the method. 5,7,[13][14][15][16][17][18][19][20] Studies in Latin American subjects, particularly Argentinians, 6 Brazilians, 4 Chileans, 21 Paraguayans, 10 and Peruvians 9 have reported age overestimation, while a tendency to underestimation was observed in Colombian individuals. 22 In Venezuelans, age overestimation has been found in samples originating in the center and the west of the country 3,23,24 and underestimation in subjects from the Andean region.…”

Introducción: la edad dental (ED) es empleada en disciplinas clínicas para evaluar si el individuo se encuentra avanzado o atrasado en su desarrollo dentario, o bien para asignar la edad de sujetos vivos o fallecidos sin documentos válidos de identificación, y es de utilidad en la práctica forense. Objetivo: estudiar la aplicabilidad de los métodos de Demirjian et al revisado (1976) y Chaillet et al en la estimación de la ED en una muestra de niños y adolescentes venezolanos. Métodos: se realizó un estudio descriptivo, retrospectivo y de campo; para ello se analizaron 516 radiografías panorámicas de pacientes de ambos sexos con edades cronológicas entre 6 y 18 años. El desarrollo dental fue evaluado en los siete dientes inferiores izquierdos mediante los estadios de maduración propuestos en el método de Demirjian et al, mientras que el cálculo de la ED fue realizado de acuerdo a las tablas de referencia proporcionadas por cada método. Se obtuvieron estadísticas descriptivas, así como diferencias de media entre la edad cronológica (EC) y la ED estimada mediante un test de Student. Resultados: se observó sobreestimación de la edad por el método de Demirjian hasta los 15 años de edad, así como subestimación de la edad con el método de Chaillet. Considerando el total de la muestra, ambos métodos subestimaron la edad (Demirjian 0,20 ± 1,46; Chaillet 0,34 ± 1,39), y la diferencia entre EC y ED fue significativa (Demirjian p = 0,0002; Chaillet p = 0,000). Conclusiones: ambos métodos pueden ser empleados en la muestra estudiada, teniendo en cuenta que la ED debe ser valorada en conjunto con otros indicadores de maduración para la evaluación del desarrollo del individuo.

“…In the scope of dental age estimation, the previous study by Olze et al had reviewed various methods of dental development staging and found that the Demirjian method can define the chronological age accurately (Olze et al 2005). In spite of that statement, another study suggested that the modification of the Demirjian method proposed by Willems showed higher accuracy in estimating age and has been tested in various populations (Willems et al 2001(Willems et al , 2012Grover et al 2012;Ambarkova et al 2014;Ye et al 2014). The Willems method was considered to be applied in the Indonesian children population because of its accuracy, and there was no established dental age estimation method for Indonesian children.…”

Background: The applicability of dental age estimation has been expanded to meet a variety of medico-legal needs, law enforcement, and disaster victim identification. The objective of this study is to examine the applicability of the Willems method for Indonesian children. Material and method: A total of 110 panoramic radiographs of the patients (6-14 years old) who met the inclusion criteria were obtained from the Department of Forensic Odontology and Department of Radiology, Universitas Airlangga, Indonesia. Estimated dental age (EDA) was assessed using the Willems method by two blinded examiners. The statistical analysis was carried out using IBM® SPSS® Statistics version 23.0 (IBM, Armonk, NY, USA). Results and discussion: The mean of the chronological age (CA) in this study is 11.30 ± 1.43 years (boys) and 11.65 ± 1.55 years (girls). The overall mean difference between CA and EDA for boys and girls is − 0.08 ± 0.76 and − 0.31 ± 0.97, respectively. This study showed that the mean age difference in girls was more significant than in boys. The growth spurt timing between boys and girls might cause a difference in dental maturation, whereas the onset of the pubertal growth spurt in girls is about 2 years earlier than in boys. In general, girls start and finish their dental development earlier than boys end. Conclusion: The present study suggests that the dental age estimation methods proposed by Willems can be considered as an applicable method for the children population in Surabaya, both boys and girls. However, a detailed study may be required while applying this approach to the 11-14-year-old girl population in Surabaya, as a substantial underestimation was observed in this community.

“…[11] The revised method was found to provide better age prediction performances, validated in and compared with different nationalities and ethnicities, if seven developing teeth are available. [12][13][14][15][16][17][18][19][20][21][22] With recent world migration issues in mind, human age estimation is triggering interest of contemporary society, expressing the need for alternative documentation of the chronological age i.e. in case of unaccompanied minor fugitives.…”
