“…Although, there was no significant different between BA and CA when using the TW3 method in females, the TW3 underestimated BA in males by an average of 2.5 months. These finding were also recently observed in the Thai population (27). Other studies on Asians have shown that young adults are reaching the end of maturity prior to the age observed through the TW3 method (7,16).…”

“…These findings are in line with the study by Alhadlaq et al who found that the bone age of children from Saudi Arabia aged 9 to 15 tended to be lower than chronological age by 8 months (10). In other Asian populations, a large number of studies have shown that the G&P atlas is not applicable due to the large differences between bone age and chronological age (7,10,(19)(20)(21)(22)(23)(24)(25)(26)(27)(11)(12)(13)(14)(15)(16)(17)(18).…”

Applicability of two bone age assessment methods to children from Saudi Arabia

Background: The Greulich & Pyle (G&P) and Tanner & Whitehouse (TW) methods are frequently used to determine bone age. The question to be raised is, "Are these standards applicable to children of different ethnicity to those on which they are based?" Methods: Bone age was assessed using the G&P and TW3 methods, firstly by independent manual rating of 2 observers, followed by a single observer using the BoneXpert software programme. In total, 420 hand trauma radiographs for Saudi Arabians (220 males, 329 left, age range 1 to 18 years) performed in the period January 2012-September 2016 were assessed. Paired sample t test was used to compare the difference between mean bone age (BA) and mean chronological age (CA) and to compare the difference between manual and BoneXpert ratings. Statistical analysis was undertaken using SPSS v.25. Findings: We found a statistically significant difference between BA and CA in males when using G&P (mean difference-0.36 ± 1 years, p <0.01) and TW3 (mean difference-0.22 ±0.9 years, p=0.03) methods but not in females for either G&P (mean difference 0.13 ± 1.2 years) or TW3 (mean difference 0.08 ± 1.1 years). In males, BoneXpert results conformed to the manual ratings for TW3 but not for G&P, for which the mean difference between manual and BoneXpert ratings was-0.27 ±0.5 years (p<0.01). Interpretation: Our results indicate that manual and BoneXpert-derived G&P and TW3 bone age assessment can be applied with no modification to Saudi Arabian females. However, only TW3 BoneXpert-derived BA can be applied without caution to Saudi Arabian males.

“…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.

“…This method cannot accurately estimate the age of the minors in this pubertal period because the variability of age increases significantly at peak age velocity. For this reason, this age assessment method of minors with a reliability of ± 2 years still remains too imprecise (5)(6)(7). Furthermore, there is a large intra and inter observer variability with the use of the Greulich-Pyle atlas (8).…”

Background: Age estimation of a minor whose identity is unknown must be accurate enough to respond to judicial requests. The main objective of this study is to accurately determine a teenager's age from simple and reproducible criteria. Samples and methods: The first reference sample consists of 1720 measurements collected from 170 teenagers aged 11 to 16, over a period of five years. A second validation sample of 735 teenage boys aged 11 to 16 made it possible to verify the relevance of our estimates. The degree of maturation was determined using 4 pubertal stages: the stage below the age of puberty; the pre-pubescent stage; the para-pubescent stage and the pubescent stage. For each pubertal stage an optimization of the values of the age was carried out in order to reduce the differences between the estimated and the actual age at the different age groups. Results: The mean differences between estimated age and actual age from this values was-0.06 ± 0.91 years for the reference group and-0.49 ± 0.73 years for validation group. Conclusions: Our method of age estimation is simpler and accurate. It could be used routinely in a forensic frame to respond to judicial requests.
