“…Dental age estimation in forensic cases may include adoption, human trafficking, asylum seekers, legal imputation, and identification of the deceased ( 12 - 18 ). Clinical applications include treatment planning and timing of therapeutic procedures in Orthodontics, Paediatric Dentistry, and Special Care in Dentistry, among other fields ( 19 - 22 ). In general, the studies that subsequently tested the application of the London Atlas for international practice sampled panoramic radiographs ( 2 - 8 ) – as these are retrospectively obtained from existing image databases in observational studies.…”

Background Assessing the dental development of children and adolescents is an important part of treatment planning. The radiographic visualization of dental developmental stages prior to age estimation is currently feasible by means of digital software apps. Testing the existing software tools is necessary to safeguard application in practice. This study applied the London Atlas Software App 2nd edition™ for dental age estimation in Brazilian children. Material and Methods The software was applied to 1.104 digital panoramic radiographs of females (n = 509) and males (n = 595) with ages between 6 and 15.99 years (mean = 10.88 ± 2.84 years). The sample included at least 100 individuals similarly distributed based on sex within 10 age categories of one year each (6├ 15.99) years. Metrics of errors were quantified between the estimated (EA) and chronological (CA) ages. Results The mean absolute errors among females and males were 0.56 and 0.60 years, respectively (overall = 0.58 years for the combined sample). The lower error values were observed in the age interval of 6 ├ 9.99 years. Error values above one year were detected in older age intervals (10 ├ 15.99 years). Statistically significant differences in dental development were not observed between females and males ( p > 0.05). Conclusions The London Atlas Software App 2nd edition led to specific error rates that can be acceptable for case-specific clinical applications. In the forensic field, caution is advised if the application is planned in the transition between late childhood and early adolescence – when third molars play a major role among the scarce developing teeth.
