“…The estimated mean age by the modified Cameriere method in our study, similar to the study by AlShahrani et al (20), was very slightly different from the chronological age. This difference, in agreement with the study by Guo et al (12), was not statistically significant.…”

“…To create a regression model, similar to the study by Cugati et al (17), gender and morphological variables such as the standardized sum of values of teeth with open apices, the number of teeth with closed apices, and their interactions were used. In some studies, other variables such as standardized values of teeth number 1 to 7 were also included in the model (2,3,12,(18)(19)(20). AlShahrani et al (20) entered the number of teeth with closed apices and standardized values of each tooth in addition to gender.…”

“…In some studies, other variables such as standardized values of teeth number 1 to 7 were also included in the model (2,3,12,(18)(19)(20). AlShahrani et al (20) entered the number of teeth with closed apices and standardized values of each tooth in addition to gender. Because some teeth may have closed apices, and the standardized value may not be defined for some teeth, it seems better to choose the sum of the standardized values as the input variable.…”

Background: In recent years, age estimation in forensic medicine has become so important. Teeth are used to estimate age as valuable indicators. Objectives: This study aimed to compare Cameriere and Demirjian methods in estimating chronological age (Age) in an Iranian population and to develop a modified Cameriere method. Methods: In this cross-sectional study, we investigated a total of 486 panoramic radiographs of individuals aged 5 - 15 years adopted from two craniofacial radiology centers in Babol, northern Iran, in 2019. The dental age of subjects was assessed by Demirjian (DAge) and Cameriere (CAge) methods and compared with their chronological age. Also, a formula was designed based on the Cameriere method for our studied population, and the results of the original and modified Cameriere (MCAge) methods were compared. Results: The mean ± SD of Age (10.38 ± 2.30) had a significant difference with DAge (10.67 ± 2.33) and CAge (9.77 ± 2.01) (P < 0.001). The modified Cameriere formula was more accurate than Cameriere one, and MCAge was 10.38 ± 2.12, indicating no significant difference with Age (P = 0.993). Conclusions: According to our results, both Demirjian and Cameriere methods were not reliable for age estimation in the Iranian population. However, the modified Cameriere formula had a very high accuracy in estimating the age of the studied population.

“…Several measurements of morphological parameters were developed for dental age estimation and calculation, such as open apex width, crown length, the ratio of open apex width to crown length, the height of the crown and coronal pulp cavity, the ratio of pulp volume to hard tissues volume, and the third molar maturity index, among others. (AlShahrani et al, 2019; Antunovic et al, 2018; Asami et al, 2019; Pinchi et al, 2015; Talabani, Baban, & Mahmood, 2015). These measurements and formulas were very useful in tooth developmental stage estimation.…”

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.
