“… reported no correlation between PTR and chronological age using sagittal and coronal sections of maxillary canine teeth on CBCT images, but there was a significant correlation using the axial section. In some studies, the correlation between chronological age and PTR differed according to tooth group, but not in other studies . In this study, central teeth were used because of the large volume of pulp, the ease of performing radiographic measurements, and the presence of a large scale age group.…”

“…Age estimation methods that are noninvasive, low cost, easy to apply, and provide definite results are preferred. Because of these advantages, the formation of secondary dentin, which leads to a reduction in the size of the pulp with aging, has been accepted as a reliable age estimation biomarker in many studies .…”

“…In addition, teeth are better suited for age estimation because they are the hardest tissue of the body, demineralization lasts for life, they are less affected by adverse conditions (mechanical, thermal, chemical, etc. ), and after death, the structure of teeth remains intact for a long time .…”

“…However, age estimation can be based on degenerative changes in teeth including periodontitis, secondary dentin formation and cementum apposition, root resorption, and root translucency in adults. Therefore, age estimation is more complicated for adults than for younger individuals .…”

This study investigated the relationship between chronological age and pulp tooth area ratio (PTR) in maxillary central teeth using cone‐beam computed tomography (CBCT) images in the Turkish population. The sample consisted of CBCT images of 120 male and female subjects between 14 and 75 years old. The PTR of the maxillary central teeth was calculated using inVivo 5 software (Anatomage, San Jose, CA). Data were analyzed with independent t‐test and Pearson's rank correlation test. There was a significant negative correlation between chronological age and PTR (r = −0.615). The results showed that the PTR of maxillary central teeth is a reliable method for age estimation in the Turkish population.

Applicability of Demirjian’s method for dental age estimation in a group of Egyptian children

AimsThe aims of this study were to evaluate the applicability of Demirjian’s method for dental age assessment in a group of Egyptian children in Minia city and to develop an age predictive equation suitable for the studied group.Subjects and methodsIn this retrospective, blind, cross-sectional study, 160 dental panoramic radiographs (DPTs) were selected from 420 DPTs from healthy children aged between three and 10 years old from the archived medical files of patients attending Minia University Dental Hospital (MUDH) and evaluated to estimate dental ages.ResultsAge was overestimated for almost all of the studied subjects with an accuracy range from 0.18 to 1.19 years for males and from 0.08 to 0.87 years for females, with the exception of two age subgroups (9–10-year-old males and 10–11-year-old females, for which the mean difference values were −0.06 and −0.008 years, respectively). A Logistic regression was used to generate a suggested formula for dental age estimation.ConclusionsDemirjian’s method may be unsuitable for Egyptian children living in Minia city. Development of a predication equation and the introduction of adaptable conversion tables to transform the maturity score into a dental age for Egyptian children may be suitable alternatives. The validity of the newly developed prediction equation must be tested among all Egyptian children.

A systematic overview of dental methods for age assessment in living individuals: from traditional to artificial intelligence-based approaches

Dental radiographies have been used for many decades for estimating the chronological age, with a view to forensic identification, migration flow control, or assessment of dental development, among others. This study aims to analyse the current application of chronological age estimation methods from dental X-ray images in the last 6 years, involving a search for works in the Scopus and PubMed databases. Exclusion criteria were applied to discard off-topic studies and experiments which are not compliant with a minimum quality standard. The studies were grouped according to the applied methodology, the estimation target, and the age cohort used to evaluate the estimation performance. A set of performance metrics was used to ensure good comparability between the different proposed methodologies. A total of 613 unique studies were retrieved, of which 286 were selected according to the inclusion criteria. Notable tendencies to overestimation and underestimation were observed in some manual approaches for numeric age estimation, being especially notable in the case of Demirjian (overestimation) and Cameriere (underestimation). On the other hand, the automatic approaches based on deep learning techniques are scarcer, with only 17 studies published in this regard, but they showed a more balanced behaviour, with no tendency to overestimation or underestimation. From the analysis of the results, it can be concluded that traditional methods have been evaluated in a wide variety of population samples, ensuring good applicability in different ethnicities. On the other hand, fully automated methods were a turning point in terms of performance, cost, and adaptability to new populations.
