Abstract For medicolegal purposes, orthodontic or orthognathic treatment various stomatological staging technique for age estimation with appliance of conventional radiographic images have been published. It remains uninvestigated if cone beam computer-tomography delivers comparable staging results to the conventional radiographic stages of third molar analysis.We conducted a retrospective cross-sectional study of 312 patients aged 13 to 21 years. Dental age estimation staging technique, introduced by Nolla and Demirjian, were applied on the left lower third molar imaged by conventional panoramic radiographs and cone beam computer-tomography. It was investigated if 2D and 3D imaging presented different staging results for dental age estimation.In 21% the Demirjian’s staging differed by a single stage between 2D and 3D images. The greatest congruence (87%) between 2D and 3D images was revealed for stage 7 (G). In contrary, stage 5 (E) presented the lowest level of congruence with 47.4%. The categorization of Nolla revealed divergences in staging for than 2 categorical variables in Nolla’s stages 3,4,5 and 6. In general, the analysis of the data displayed the divergence for Nolla’s stages 4 to 8. The staging results for 2D and 3D imaging in accordance to the rules of Nolla and Demirjian showed significant differences. Individuals of 18 years may present immature third molars, thus merely an immature third molar cannot reject legal majority.Nolla’s and Demirjian’s 2D and 3D imaging present significantly different staging results.

Introduction: Age estimation is an important aspect in forensic anthropology, as it can aid in the identification of the deceased, and can be used in cases of immigration, child abuse and criminal prosecution in living individuals. Dental age estimation is considered reliable and accurate, since tooth development is least affected by environmental factors compared to somatic growth.Methods: In total, 150 pre-orthodontic treatment radiographs from healthy individuals were assessed. These individuals were aged between 8 to 19 years. Dental age for these individuals was calculated by two methods: Demirjian’s eight teeth method and Willems method. For Willems method, seven teeth on the left side of mandible (except the third molar) were staged according to Demirjian’s staging, and for Demirjian’s eight teeth method, all eight teeth were staged.Results: The mean chronological ages were 13.6961±1.94384 years in males and 13.9204±2.63541 years in females. The mean estimated ages by Demirjian’s eight teeth method were 12.1856±1.73478 years and 11.7906±2.32344 years in males and females respectively. Similarly, the mean estimated ages by Willems method were 12.8958±1.46838 years in males and 12.6926±2.27807 years in females.Conclusions: Willems method and Demirjian’s eight teeth method underestimated the chronological age in the given population. Both methods showed excellent correlation with chronological age indicating their applicability in dental age estimation, with development of population specific scores.

This study was performed to review the international techniques for third molar dental age estimation applied to Brazilian adolescents. A systematic literature review was structured according to PRISMA. Six primary electronic databases were searched (PubMed, Scopus, LILACS, SciELO, Embase and Web of Science) and two sources of grey literature (Open Grey and Open Thesis) were screened. Only cross-sectional studies were included. The risk of bias was assessed with Joanna Briggs Institute tool for systematic reviews. The initial search found 2284 studies. Ten studies fulfilled the eligibility criteria. The samples varied between 288 and 2097 individuals. The sampled age interval ranged from 5 to 23 years. Seven techniques were found within the eligible studies. All the studies had low risk of bias. Three techniques: Demirjian (DEM), Nicodemo (NIC) and Cameriere (I3M) were included in the quantitative analysis. For each of the developmental stages of the techniques DEM and NIC, as well as for each measuring ratio of I3M, combined age values between studies were reported. In general, the international techniques for dental age estimation based on the radiographic assessment of the third molars were applicable to the Brazilian population.
