“…In living individuals, judicial challenges must be solved when valid identification documents are lacking [2, 3]. While cementum or dentine can be studied in dead bodies, the focus for the living is on the clinical situation and radiographs [4]. Root development, periodontium, ratio between pulp and tooth or tooth and root of permanent teeth can be measured radiologically.…”

BackgroundThe aim of the study was to compare two frequently used dental age estimation methods for accuracy.MethodsA total of 479 panoramic radiographs in age groups 6–14 years from a German population were evaluated. The dental age of 268 boys and 211 girls was assessed by means of the method of Demirjian (1973) and Cameriere (2006) and compared with their actual chronological age.ResultsDemirjan’s method showed an overestimation of dental age compared to chronological age in all age groups for boys (mean difference −0.16, p = 0.010, range −0.35 to 0.09), age group 9 showed an underestimation. Using the same method for girls (mean difference −0.18, p = 0.008, range −0.45 to 0.13), an overestimation could also be shown in all age groups except for age groups 8 and 13. Results for Cameriere’s method showed for boys (mean difference 0.07, p = 0.314, range −1.38 to 3.83) in age groups 6 to 11 an overestimation, but in age groups 12 to14 an underestimation. The results for girls (mean difference 0.08, p = 0.480, range −1.55 to 4.51) showed an overestimation for age groups from 6 to 10, and an underestimation in age groups 11 to 14.ConclusionsThe comparison shows an advantage of Demirjian’s method for both genders. While Cameriere’s method showed a higher inaccuracy in all age groups, Demirjian’s method showed more appropriate results for dental age estimation of the investigated German population. To avoid errors in forensic age estimation and to prevent misidentifications for defendants in criminal processes, further studies of more precise methods for age estimation for the German population are required.

“…In the literature, discrepancies of many years, sometimes even decades, between assumed and true age have been reported. In a study combining the clinical and radiological dental status of patients, deviations of 14 to 17 years in men, and 12 to 15 years in women to the chronological age were reported [37]. In a study by Olze [51], the combination of the DMFT indices of all permanent teeth, the DMFT indices of the third molars, the eruption time of the third molars and the degree of periodontal destruction around the second molars only yielded correct age values for 69.7% of the men and 71.4% of the women.…”

The developmental stages of the first and second dentition, combined with abrasive wear of the dental hard tissue can be used for age determination in many mammal species and in humans. Concerning dental age determination, one has to distinguish between invasive techniques, which are mainly applied in dead individuals, and non-invasive methods suitable for living individuals. In contrast to in adults, where only few parameters are available for orientation, age determination in children and adolescents is in general fairly easy, and is facilitated by stereotypical biological growth patterns. In the present article, different methods for dental age determination are introduced, with a special focus on the fields of application, and on the limits of age determination. With increasing age, the number of valid and meaningful dental characteristics diminishes, and therefore the accuracy of dental age assessment decreases.

“…From a forensic perspective, sufficiently precise and reliable determination of age is required. There is an increasing demand by the courts for appropriate estimation of age in living individuals, suspected of being minors in the absence of legal documentation of age in criminal cases, adoptions, asylum‐seekers, refugees, and immigrants (3, 4). Various methods have been used to estimate age for medico‐legal purposes, but the radiological evaluation of dental age is considered as the most accurate method.…”

Teeth development is widely used for age estimation in forensic science. The aims of this study were as follows: first, to establish Indian data on canine and first premolar development for age estimation and second, to investigate population differences in teeth development. Orthopantomograms of 340 Indian children aged between 5 and 14 years were analyzed. Demirjian's stages were recorded for the developmental evaluation of canine and first premolar and for further descriptive statistical analysis. A two-way ANOVA was performed to test the significance of difference in teeth development by sex and stage. A one-way ANOVA was performed to investigate population differences in teeth development. Results showed statistically significant differences in teeth development by sex and stage. Accordingly, teeth development was earlier in girls. No statistically significant differences were observed in timings of Demirjian's stages among different populations. In conclusion, the findings of this study could be used for age estimation of Indian children.
