“…Willems's method [1] based on a reference Belgian model, for instance, has been tested in Brazilians [15], Indonesians [7], Kenyans [5], Kosovar [9], Malay [24], Saudi Arabians [4], Somali [8], Sri Lankan [28], Tibetans [6], Venezuelans [29] and children from many other nationalities. Despite the existing studies that rank other methods before Willems' [30][31][32][33], the overall perception of the method in the scienti c literature is that it is predominantly endorsed across populations.…”

Objectives 1) to test the Willems’ dental age estimation method in different geographic samples of the Brazilian population, and 2) to propose a new model combining the geographic samples in a single reference table of Brazilian maturity scores. Material and methods The sample consisted of 5017 panoramic radiographs of Brazilian males (n = 2443) and females (n = 2574) between 6 and 15.99 years (mean age = 10.99 ± 2.76 years). The radiographs were collected from the Southeastern (SE) (n = 2920), Central-Western (CW) (n = 1176), and Southern (SO) (n = 921) geographic regions. Demirjian’s technique, was applied followed by Willem’s method and the proposed new model. Results Willems’ method led to mean absolute errors (MAE) of 0.79 and 0.81 years for males and females, respectively. Root mean squared errors (RMSE) were 1.01 and 1.03 years, respectively. The Brazilian model led to MAE of 0.72 and 0.74 years for males and females, respectively, and RMSE of 0.93 years for both sexes. The MAE was reduced in 70% of the age categories. Differences between regions were statistically (p < 0.05) but not clinically significant. Conclusion The new model based on a combined population had an enhanced performance compared to Willems’ model and led to reference outcomes for Brazilians. Clinical relevance: Assessing patients’ biological development by means of dental analysis is relevant to plan orthopedic treatments and follow up. Having a combined-region statistic model for dental age estimation of Brazilian children contributes to optimal dental age estimation practices.

“…These structures were chosen for many reasons: compared with other parts of the body, images can be obtained with lower amounts of radiation, and many bones or teeth are generally available. In the last few years, within the ambit of the AgEstimation Project, several works have been published on the problem of age estimation for forensic purposes in young subjects, including methods using both teeth and the bones of the hand/wrist [24][25][26][27][28]. Pediatricians and auxologists in clinical practice generally use growth curves based on known chronological age to investigate and monitor a patient's physical development.…”

Accurate methods of age estimation are more essential than ever due to the rise in undocumented individuals without proper identification, often linked to illegal immigration and criminal activities. This absence of reliable records presents challenges within the legal systems, where age thresholds in the context of children’s rights vary across countries. Age 14 has global significance, as established by the UN Convention on the Rights of the Child and the EU for administrative purposes. Accurate age estimation is crucial in medical decisions, reproductive health, and forensics. This study focuses on age estimation via dental radiographs, proposing a method for estimating the likelihood of having attained the age of 14. Orthopantomograms were analyzed from two samples, 191 Italian children (aged 5–15) and 822 Chilean subjects (aged 11–22), using dental maturity indices. These indices evaluated open tooth apices and complete root development. Statistical analysis confirmed the method’s reliability in identifying individuals aged 14 or older, with sex-specific cut-offs. The proposed method particularly advocates an approach based on dental mineralization, which could surpass those relying on bone growth. The collaboration between medical experts, including pediatricians and diagnostic imaging specialists, is vital for standardized age estimation strategies. Ethical concerns regarding radiation exposure and accountability are recognized, although the method’s low radiation doses are deemed acceptable. The proposed method will help health professionals to accurately predict whether or not the 14-year threshold has been reached, opening up new avenues of medico-legal interest and laying the foundations for a legal framework that would allow the pediatrician, when involved, to use a valid and recognized diagnostic approach.

“…The results of the Willems method were more or less similar to previous research in the Eastern Turkish and Tunisian populations [ 3 , 24 ]. In contrast, the Croatian and Sri Lankan population-specific studies reported a lower error rate using the Willems method [ 25 , 26 ]. In addition, the dental age estimates also show that the London Atlas was more accurate than Willems’ method ( p < 0.001), which is in accordance with literature that sampled children with molar-incisor hypomineralization [ 27 ], though Alaettin Koç and Bianca Gelbrich’s early study [ 3 , 19 ] displayed no statistical precision difference between those two methods ( p > 0.05).…”

Background Numerous dental age estimation methods have been devised and practised for decades. Among these, the London Atlas and Willems methods were two of the most frequently adopted, however dependent on atlantes or tables. A new estimation method less reliant on external measurement could be efficient and economical. Aim This study aimed to evaluate the utility and applicability of the dental age estimation methods of London Atlas, Willems, and a new quick method that subtracts the number of developing teeth from the universal root mature age of 16 years in one of the lower quadrants reported in this work among Chinese Uyghur children. Methods A comparative cross-sectional study was conducted. Subjects enrolled in the study were screened according to preset inclusion and exclusion criteria. The observer then obtained the dental age from the subjects’ panoramic radiographs based on the estimated rules of the London Atlas, Willems, and a new quick method. Paired t-test was used to compare the accuracy and precision of the above three estimation methods. Independent-sample t-test was used to find the difference between gender. Results Totally, 831 radiographs entered the analyses of this study. Among the three methods evaluated, the Willems method, in particular, showed a distinct underestimated tendency. The mean error of the dental age predicted by the London Atlas, the Willems method, and the quick method was 0.06 ± 1.13 years, 0.44 ± 1.14 years, and 0.30 ± 0.63 years, respectively. The mean absolute error was 0.86 ± 0.75 years according to the London Atlas, 1.17 ± 0.89 years under the Willems method, and 0.70 ± 0.54 years under our quick method. No significant difference was found between the chronological age and dental age using the London Atlas, generally for the 10 to 15 years group (p > 0.05), but our quick method for the 15–16 years children (p < 0.05) and Willems method (p < 0.001). Conclusion The London Atlas outperformed the Willems method with better accuracy and precision among 10–15 years Chinese Uyghur children. Our new quick method may be comparable to the London Atlas for children aged 10–14 and potentially become a more straightforward dental age prediction instrument.
