“…Radiographs belonging to patients with a medical history of endocrinal disorders were also excluded. The chronological age was calculated as the difference between the date of the radiography and the date of birth [19][20][21]. The study group was divided into nine age groups by year of chronological age.…”

This study aimed to validate Lee’s age estimation method and assess the 18-year threshold in Korean and Japanese populations. We evaluated the maxillary and mandibular second (M2) and third molars (M3) in 2657 orthopantomograms of the Korean and Japanese populations aged 15–23 years (19.47±2.62 years for Koreans, 19.31±2.60 years for Japanese), using Demirjian’s criteria. Dental age was estimated, and correlations between chronological and dental ages were analyzed. Classification performance was calculated based on the 18-year threshold. The relationship between developmental stage and chronologic age was analyzed using multiple linear regression. Our results revealed that Lee’s method was appropriate for estimation in the Korean population. When the Lee’s method was applied to the Japanese population, a lower value of correlation coefficients between estimated and chronological age, and lower specificity were observed. Population differences were observed predominantly in the stages of root development (stages F and G) of M2s and M3s in both jaws and more frequently in females than in males. In the multiple linear regression between developmental stage and chronological age, lower values of adjusted r2 were observed in the Japanese population than in the Koreans. In conclusion, the Lee’s method derived from the Korean population data might be unsuitable for Japanese juveniles and adolescents. To support the findings of this study, future studies with samples from multiple institutions should be conducted. Future studies with larger sample sizes are also warranted to improve the accuracy of dental age estimation and confirm the developmental pattern of teeth in the Japanese population.

“…1 In children and adolescents, there are different medico-legal and forensic questions, like the age of criminal responsibility or adult age, where dental age estimation can help to answer. [2][3][4][5][6] According to the Study Group on Forensic Age Diagnostics (AGFAD; http://agfad.uni-muenster.de) 2 , the examination of different independent developmental systems including teeth is combined, to increase the accuracy of estimated age. 7 For children and juveniles, the radiographs of hand-wrist and the teeth are the most reliable for assessing skeletal and dental development.…”

“…In previous studies, the accuracy of the I 3M in age estimation for other populations has been conducted by OPTs to date 3,4,7–34 . In our study, we investigated, for the first time, the accuracy and applicability of the I 3M for discriminating Turkish minors from adults, and its relationship with CA using CBCT.…”

“…The accuracy of the I 3M in age estimation for other populations has been conducted by OPTs to date 3,4,7–34 . However, OPTs have disadvantages, such as distortion, magnification, and lack of cross-sectional data, and are limited in ensuring the accuracy of a 3-dimensional (3D) object.…”

“…This cutoff value, which has also been examined in various populations, has demonstrated high sensitivity and specificity. These additional studies have revealed that I 3M might also be used as a practical predictor of age 18 years in European, 3,8,[10][11][12][13][14][15][16][17][18][19][20] African, 7,[21][22][23][24] Asian, 4,25-28 American, 9,[29][30][31][32][33] and Oceanian 34 populations.…”

This retrospective study aimed to evaluate the accuracy and applicability of the third molar maturity index (I3M) for discriminating Turkish minors from adults, and its relationship with chronological age using cone beam computed tomography (CBCT). A total of 122 CBCT scans of Turkish individuals (55 boys and 67 girls) aged 13 to 23 years were evaluated using the I3M cutoff value. Chronological age gradually decreased as the I3M value increased. The overall accuracy was 95.9%. The sensitivity and specificity of this test were 93.5% and 97.4%, respectively. Positive predictive value was 95.6%. The intraclass correlation coefficient values of the I3M for the intraobserver and interobserver agreements were 0.998 and 0.996, respectively. This study showed relatively higher reproducibility of measurements on CBCT scans than on panoramic radiographs in the literature. Cone beam computed tomography may be advantageous and preferred over panoramic radiographs in distinguishing the legal age threshold of 18 years according to Cameriere's method when a more extensive investigation is needed to support the solution of challenging and uncertain cases in forensic medicine.
