“…According to statistical results, the vast majority of cases were in the age group of more than 18 years and the reason for this is that this age group is more in need of citizenship or civil status ID for work, travel, and marriage. This finding agrees with a study done previously [5].…”

stimation of age is helpful in both civil and criminal cases. In the living individual age estimation is the most important issue to the court and the common citizens as well. The present study was carried out to study the estimation of age by epiphyses fusion at the knee joint, which is considered one of the modern and somewhat accurate methods of estimating age.Purpose. To compare chronological age and age estimated according to the union from radiographic assessment of epiphyseal fusion at the knee joint in a sample of the Iraq population and to implement radiographic examination of the knee joint as an additional anatomical region for age estimation.Materials and Methods. A prospective study was carried out on 55 medico-legal cases referred to the medico-legal directorate in Baghdad during 6-month period in 2022. The cases under study were classified into 2 groups: male (30) and female (25), their age ranged from (9-19 years). Radiographic method (anteroposterior and lateral knee x-ray) was used to subdivide the continuum of development into 5 specific stages of union and scored as stage 0 -nonunion, stage 1 -beginning union, stage 2 -active union, stage 3 -recent union, stage 4 -complete union.Results. The present study showed that out of the total of 55 cases, 30 cases were male and 25 were female. A maximum number of cases belong to the 18-19 years of age group in both genders. The chronological age (years) of the youngest and oldest subjects was recorded at each stage of union for each of the three epiphyses at the knee for males and females. The mean age and stander deviation for each stage of fusion were mentioned. The mean age in males; at stage 0 was about 10.5 for all three bones (distal end of femur and proximal end of tibia and fibula). Stage 1 was about 13 years for the proximal end of the femur, 13.5 years for the distal end of the tibia, and 14 years for the distal end of the fibula. Stage 2 was about 15.5 years for all three bones, while in stage 3; the mean age for all three bones was about 17.5 years and regarding stage 4; the mean age was 18.5 years for the proximal end of the femur and 19 for distal end for both tibia and fibula. Females were less than males by about 1.5 years.Conclusion. The present study concluded that the stage of epiphyseal union is correlated with chronological age in both males and females. Mean age gradually increases with each stage of union and also varies between male and female cases. A statistically significant difference in mean age was recorded between stages when compared to the previous stage for three epiphyses. Fusion of various epiphyses has been reported earlier in females (about 1.5 years) in comparison to males of the present series. Epiphyseal fusion of the lower end of the femur was observed earlier than the tibia and fibula.

“…The value of teeth in assessing individual age is widely accepted in forensic sciences and numerous areas of human life, such as socioeconomic, legal aspects, and dental treatment planning (Koshy and Tandon 1998;Franco et al 2013). Several studies have been performed on the estimation of human biological age (Cameriere et al 2004); most of those are focused on skeletal markers (Priya 2017) such as epiphyseal and cranial suture fusions (Ebeye et al 2016), hand-wrist bones (Benjavongkulchai and Pittayapat 2018), sternoclavicular bones (Ufuk et al 2016), and dental maturation (Manjunatha and Soni 2014).…”

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.

“…7,8 Many studies in forensic fields deal with the estimation of biological age in humans have been developed. 9 The most common methods rely on skeletal indicators 10 such as epiphyseal fusion, 11 hand-wrist bones, 12 sternoclavicular bones, 13 cranial sutures fusion and dental maturation. 14 According to the previous study, the radiograph of the hand-wrist and dental development is the most reliable method for assessing the biological age of children and juveniles.…”

Dental age estimation methods have been developed in such a way as to fulfill various requirements of medico-legal, law enforcement, and victim identification in mass disasters. This study aimed to evaluate the accuracy of the Willems dental age estimation method for children in Indonesia. The estimated dental age (EDA) was assessed using the Willems method by two examiners. The statistical analysis was carried out using IBM® SPSS® Statistics version 23.0 (IBM, Armonk, New York, USA). The results obtained 92 panoramic radiographs ranging in age from 8 to 14 years from the Departments of Forensic Odontology and Radiology, Universitas Airlangga, Surabaya, Indonesia. The average chronological age (CA) of the subjects in this study was 11.30+1.43 years for boys and 11.65+1.55 years for girls. The overall mean differences between the CA and the EDA for boys and girls were -0.08+0.76 and -0.31+0.97. In this study, the mean age difference was more significant in girls than in boys. The difference in growth spurt timing between boys and girls may explain the difference in dental maturation, as girls begin their pubertal growth spurt about two years earlier than boys. In general, girls' dental development begins and ends earlier than boys'. In conclusion, the dental age estimation method proposed by Willems can be applied to boys, as there is no significant statistical difference. However, when applying this method to girls, a thorough analysis may be required.Keywords: chronological age; dental age; forensic odontology; human rights; justice
