“…The non-LATAM countries with the greatest collaborations were Russia (15 studies), the UK (10 studies), and Italy (8 studies). Two publications involved large multi-ethnic studies to validate the third molar maturity index in European, Asian (Angelakopoulos et al, 2021) and African (Angelakopoulos et al, 2023) countries, including Brazil, Chile, Peru, and the Dominican Republic. The LATAM researcher with the highest productivity was Prof. Ademir Franco, with declared affiliations to the São Leopoldo Mandic School of Dentistry (Campinas, Brazil), the Department of Imaging and Pathology, Forensic Odontology, KU Leuven (Leuven, Belgium), the Center of Forensic and Legal Medicine and Dentistry, University of Dundee (Scotland, UK), and the Department of Therapeutic Stomatology, Sechenov University (Moscow, Russia).…”

The new paradigm in Forensic Sciences initiated by the entry of genetics (the current standard of legal evidence) and accentuated by recognized wrongful convictions derived from experts today in the eye of criticism, has highlighted the potential for bias and error in forensic disciplines when they depend on human interpretation and subjectivity, which has not been avoided by Forensic Odontology (FO). However, a subjective judgment is not necessarily wrong, so the refinement of processes, the development of standards, and robust research can contribute to the validity of interpretation to increase objectivity. Latin America (LATAM) has its own realities and needs, which have conditioned the priorities and objectives of FO research. A scoping review is presented to systematically map the investigation of LATAM researchers and identify the objective or subjective nature of their assessments. LATAM shows interesting productivity and intentions to adhere to international standards, with Brazil leading this research significantly, followed by Chile and Colombia, among others. However, there is a disproportionate approach in certain lines of research (dental age estimation), and needs to address other quantitative studies, and to improve the visibility of the LATAM FO research.

“…However, another method developed by Cameriere using a third-molar maturity index seems to show much better accuracy and could be used to determine if an individual is over 18 years old with 99.9% probability in some situations when combined with other physical and radiological examinations [28]. This method has been adapted to many ethnicities [29,30].…”

European countries have become host countries for migrants and unaccompanied minors. However, many migrants arrive without identity documents. Many methods exist to estimate age; among them, several methods using dental age have been proposed. Our objective was to evaluate the accuracy of biological age determination in a multiethnic sample using dental age estimated using three methods: Nolla, Demirjian, and the London Atlas. Orthopantomograms collected for 324 patients of various ethnicities aged from 4 to 20 years old were included. Then, for each orthopantomogram, a blind trained examiner used the three methods of age estimation. For each method, the estimated mean age was greater than the real mean age (p < 0.0001). The accuracy after 18 years old with a 1-year margin was under 50%. Demirjian’s method gave a less accurate estimated age than Nolla’s method (p < 0.0001) or the London Atlas (p < 0.001). The most accurate methods were those of Nolla and the London Atlas, with average absolute deviations of 1.3 and 1.2 years, respectively. Demirjian’s method was much less accurate, with a deviation of around 2 years. The evaluated methods are unable to provide reliable information to determine if an individual is a minor.

“…Chronological age estimation allows the dentist to evaluate the progress and determine the most appropriate treatment for different dental malocclusions based on the children's craniofacial development [ 2 , 3 ]. There are several age estimation indices, such as the third molar maturity index, and various methods, such as general physical examination, molecular biomarkers (e.g., DNA methylation), multiphoton microscopy, left-handed radiographic images, and dental images [ 4 – 7 ]. In order to increase the accuracy of age estimation and improve diagnostic standards, the field of forensic age diagnosis recommends that an X-ray examination of the left hand, a dental growth assessment, and physical examination tests be performed in a combined manner [ 8 ].…”

Background: The stage of tooth formation is one of the most reliable indicators for predicting a patient’s developmental age by radiographs. This study compared the accuracy of three distinct dental age estimation methods (Demirjian, Nolla, and Willems) in children aged 3–17 in the northern Iranian population.Methods: This cross‐sectional study examined panoramic radiographs of 434 children aged 3–17 from Mazandaran Province, Iran, who had teeth 31–37 present on the left mandible. This study employed the Demirjian, Nolla, and Willems methods to estimate the dental age of the sample and compare it with the chronological age. The data were analyzed using SPSS v16. A paired t‐test was used to compare chronological and dental ages. The Pearson correlation was used to correlate the chronological and dental ages. The errors of different methods were compared using the Wilcoxon test. P values < 0.05 were considered significant for all tests except Wilcoxon. For Wilcoxon, a P value < 0.017 was considered significant.Results: The three methods presented differing mean estimated ages. The Demirjian method delivered the highest mean, and all three methods differed significantly when compared in pairs. The results showed that the Demirjian method overestimated chronological age by 0.25 years (P < 0.001) in girls and 0.09 years (P = 0.28) in boys. The Willems method underestimated chronological age by 0.05 years (P = 0.47) in girls and 0.12 years (P = 0.13) in boys. The Nolla method underestimated chronological age by 0.41 years (P < 0.001) in girls and 0.40 years (P < 0.001) in boys. The accuracy of each method varied with the patient’s age.Conclusion: According to the findings, the Willems method outperformed the Demirjian method, and the Demirjian method exceeded the Nolla method for estimating dental age in Iranian children aged 3–17. Overall, the Demirjian method overestimated the age of the study population, whereas the other two underestimated it.
