“…4 ), we demonstrated alike maturation of third molars in both males and females, which is in line with similar studies 14 – 16 , 19 – 23 , 44 , 51 . Previous European studies present slightly better accuracy and sensibility in males than in females 14 – 16 , 19 – 23 , 44 , 51 . Contrary, females presented better specificity than males 14 – 16 , 19 – 23 , 44 , 51 .…”

“…Estimated post-test probability of both male (94.7%; 95% CI 93.1–96.3%) and female (96.2%; 95% CI 94.8–97.5%) demonstrated results compatible with other European studies 2 , 14 , 15 , 19 – 23 , 44 , 51 . It is important to refer that Zelic et al 20 and Kelmendi et al 21 reported results very close to 100% in females, and Gulsahi et al 19 reported results of 100% in both sexes, although the sample size was one of the smallest in all European studies (n = 293), which may influence these results.…”

Contrary, females presented better specificity than males 14 – 16 , 19 – 23 , 44 , 51 . Therefore, I 3M seems to be slightly more accurate in males, although it is equivalent to the female participants in this Portuguese population.…”

“…The effect of age on I 3M performance is proposed to rely on the maturation development according to sex as women tend to develop at a younger ages than men 52 . This maturation difference is suggested to explain the I 3M results discrepancies between both sexes, however more studies are needed to fully understand the biological reasons upon this subject 19 , 41 , 51 .

Age estimation is a major step in forensic and legal procedures. Its relevance has been increasing due to growing society issues, such as identification of missing people, crimes against minors or lack of valid identification papers from locals or foreigners. Evaluation of the cut-off value of the Third Molar Maturation Index (I3M) = 0.08 for discriminating minors from adults in the Portuguese population. The left lower third molars were analysed by applying a specific cut-off value of 0.08 determined by Cameriere et al. in 2008. A sample of 778 digital panoramic radiographs of a representative Portuguese sample (442 females and 336 males), in the age range of 12–24 years (mean age 17.7 ± 2.98 years in females and 18.1 ± 3.0 years in males), was retrospectively evaluated. I3M decreased as the real age gradually increased in both sexes. The 0.08 cut-off score was valuable in discriminating adults from minors. According to the pooled results, the accuracy, by means of area under the curve, was 92.8% (95% confidence interval (CI) 91.0–94.6%). The proportion of correctly classified subjects (sensitivity) was 90.7% (95% CI 88.7–92.8%) and the specificity was 94.9% (95% CI 93.3–96.4%). The results show that I3M is a valuable method to differentiate minors from adults in the Portuguese population.

Tooth developmental stage evaluation is important in dental and chronological age estimation, and it is important for accurate diagnoses and appropriate treatment in dental practice. It is routinely assessed by clinical observations and radiographic techniques. This study aimed at ascertaining tooth developmental stage judgments made by examiners and Mimics software according to the Nolla method with radiographs. Meanwhile, the true tooth developmental stages would be explored with histological analysis. Twenty freshly slaughtered porcine heads were collected and hemisected, and both the left and right mandibular samples were numbered. The developmental stages of the second and third permanent molars (M2 and M3) were evaluated by examiners and Mimics software analysis. The ratio of the radiopaque calcified area to the dental follicle (RCA/DF) at different stages was calculated. Both non-decalcified and decalcified samples were processed for histologic observation. The results showed significant differences between RCA/DF ratios from different developmental stages. There was a high positive correlation between the examiners' evaluation results and Mimics analysis results. Radiograph judgments and histology observation results were consistent from Stages 2-6. However, radiograph images of Stage 1 samples showed only crypts present, while under a surgical operating microscope, a bell-shaped tooth germ was observed. This was also confirmed by normal and hard tissue histology. In conclusion, radiograph judgments made by either examiners or Mimics software were both reliable. Mimics analysis can be a useful tool in evaluating tooth developmental stages. However, judgments need to be made cautiously in early developmental stages.
