Objective: Estimating age from dental development is a useful indicator that is considered highly reliable and can be of great help in determining an individual’s age, although the accuracy of different methods has not been systematically investigated. The aim of this study was to evaluate images of conventional digital panoramic radiographs (CP) and panoramic reformats (PR) obtained from cone beam computed tomography (CBCT) in order to confirm the similarity of the methods. Material and Methods: A sample of 20 patients who had conventional panoramic radiographs (CP) and also CBCT exams was evaluated. These examinations were performed on the same date, so there was no variation in the mineralization stage in the different images. The images were analyzed by a dentist, a specialist in Radiology and Imaging, and, before the beginning of the analysis, an intra-examiner calibration was performed, resulting in a good Kappa index evaluation (> 0.5). Results: In this study, age estimation based on mineralization analysis of mandibular third molar teeth was not altered when using PR (CBCT) or CP. The difference in median values between the two groups is no statistically significant difference. Conclusion: The methods evaluated were found to be consistent with one another, thereby confirming the similarity of their efficacy.
