“…Similar observations were noticed by Jashwant A Darji et al, who found a statistically significant sex difference in age [6]. But there could be variations in dental development between individuals and between different population groups in different regions [7].…”

“…This fact can be explained by their morphology, radiolucency and location, and because they are major elements, with well demarcated radiopacity, located in better radiographic viewing areas and with earlier formation compared to upper elements [18].…”

“…Regarding the anatomical location, the mandibular region has a greater and thicker bone area with fewer structures that could superimpose images during the radiographic procedure, thus contributing to a better view of the lower elements [18].…”

“…Many Forensic Medicine Institutes of Brazil do not have equipment to perform imaging tests on their premises, either due to the lack of maintenance or to investments, hindering the age estimation investigation [18]. In developed countries, this scenario appears to be different, since institutes have equipment for such a purpose, quickly obtaining radiographs and availability to perform CT scans of execution and / or resonances for the elaboration of reports.…”

Objective: To evaluate the agreement and applicability of the Chronological Dental Mineralization Table of Nicodemo, Moraes and Medici Filho (1974) to estimate age held by undergraduate Dentistry students at the Federal University of Paraíba. Material and Methods: Field research applied with a sample of 50 students according to inclusion and exclusion criteria. Sequentially, 3 panoramic radiographs were exposed (actual age known only by teachers), and students were instructed to interpret them from the selection of 2-4 teeth under formation. Data were analyzed using SPSS software (Statistical Package for Social Sciences), version 20.0, adopting significance level of 5%. Results: Most students chose 3 teeth, with percentages of 56.0% (n = 28); 38.0% (n = 19) and 58.0% (n = 29) for radiographs 1, 2 and 3, respectively. Teeth selected with greater frequency were: 47 (20.1%, n = 33) and 45 (19.5%, n = 32) -radiography 1; 38 (22.7%, n = 32) and 18 (13.4%, n = 19) -radiography 2; and 47 (17.9%; n = 26) and 36 (13.7%; n = 20) -radiography 3. The agreement between estimated and actual ages was 60.0% for radiography 1, 12.0% for radiography 2 and 32.0% for radiography 3. Age was underestimated in 40.0% (n = 20) and 88.0% (n = 44) in radiographs 1 and 2, respectively. Overestimation of the actual age occurred only in radiography 3 (68.0%; n = 34). The linear regression analysis revealed that it is possible to estimate the actual age from the maximum age stipulated by training students with 88.1% success rate. Conclusion: The method is applicable; however, the correlation between estimated and actual ages varied considerably among radiographs, and maximum estimated values were closer to the actual age than minimum values.

Age estimation methods through developmental atlases are simplified by image comparison using radiographs. Atlas‐based methods have been utilized to create population‐specific charts addressing population diversity. To tackle the absence of a dedicated atlas for the Brazilian population, the objective of the present study was to create a new atlas for dental development in Brazil based on the London Atlas chart. The new atlas (RP Atlas) is based on the median of tooth development, eruption, and resorption in individuals aged 5 to 23. The sample (567 individuals) was divided between females (n = 290) and males (n = 277). The RP Atlas was handcrafted, scanned, colored, and clustered in two atlases divided by sex. The development of a specific atlas for the Brazilian population has the potential to enhance the accuracy of age estimation in forensic scenarios, notably in a mixed country like Brazil. Further research is needed to assess the suitability of the newly developed atlas for the Brazilian population.
