Summary: The estimation of dental age using cementum incremental lines (CIL) is a widely studied method, but its reliability is still uncertain. This article conducted a literature review and meta-analysis to assess the reliability of CIL as a biological indicator for estimating dental age. The results showed that there is scientific evidence supporting the high correlation between age estimated by CIL count and chronological age, and no publication bias was found. Therefore, CIL can be considered as a reliable method for estimating dental age, but a standardized protocol and rigorous selection of the root area for analysis are necessary.

Summary: This study assessed the precision and congruence of counting tooth cementum annulations (TCA) as a method for estimating the age at death of adults. The results showed high reliability and moderate accuracy of TCA analysis, with decreasing accuracy in older individuals. It is recommended to use multiple age estimation methods to verify the reliability of assessments.

Summary: This study aimed to investigate whether micro-CT analysis of pubic bone samples obtained from the contemporary Serbian population could be used for age-at-death estimation in anthropological and forensic practice. The results showed that the micro-architectural features of trabecular and cortical compartments of pubic bone could potentially serve as a reliable method for age-at-death estimation in the Serbian population.

Summary: This article evaluates the feasibility of using a module to accurately quantify cementum deposits and compares the module's performance to that of a human expert. The study found that the automated module produced reliable and reproducible counts with a higher global precision than the human expert, but it showed higher sensitivity to taphonomic damages and did not avoid the trajectory effect described for age-at-death estimation in adults.

Summary: This study proposes a new method based on multifactorial macroscopic analysis and deep random neural network models to estimate the age of skeletal remains in adults. The results demonstrate that age estimation can be accurately inferred across the entire adult age span, with informative estimates and prediction intervals obtained for the elderly population.

Summary: Since the publication of Lamendin's age estimation technique, the use of root dentin translucency as an indicator of age has garnered attention. Parra and colleagues proposed the Forensic International Dental Database (FIDB), a method based on Bayes theorem and Lamendin's technique, to estimate age at death in adults. This study aims to update and evaluate a new version of the method (FIDBv2) using samples from Colombia and Greece, showing its acceptable performance and suitability for age estimation in various forensic contexts. The FIDBv2 is considered a reliable alternative in situations where additional data is unavailable, and its applicability is not limited to specific populations.

Summary: Age estimation is a crucial process in legal cases and adoption procedures. Various methods based on skeletal and dental growth have been used, but few studies have compared these methods to determine their reliability in different conditions and age ranges, hindering the development of standardized guidelines for age estimation. A comparison of dental and skeletal methods on a group of 94 children aged between 0 and 8 years revealed differences in accuracy, with diagram methods showing lower error ranges compared to traditional methods.

Summary: Age estimation is crucial in identifying human skeletal remains, but it is more challenging in adult individuals. This article presents the application of aspartic acid racemization, a biochemical technique, in accurately determining age in a Spanish sample. Further studies and the combination of this technique with forensic anthropology methods are needed to improve age estimation in forensic cases.

Summary: In this study, the mineralization stages of permanent teeth in Brazilian individuals were evaluated using digital panoramic radiographs. The results showed no correlation between the chronology of mineralization stages and sex, except for canines. Numerical tables of the chronology of dental mineralization stages were prepared based on the findings.

Summary: Despite the considerable number of methods available, age estimation of human remains remains a challenge in forensic anthropology, especially for mature adults. This study proposes a combined method using the Suchey-Brooks method and pubic bone density measurement for age estimation, showing a significant negative correlation between bone density and age, with good accuracy especially for mature adults.

Summary: The present study aims to analyze the influence of light settings on age estimation methods. The results indicate that light settings may affect the visual perception of root translucency and thus impact the accuracy of age estimation methods.

Summary: Identification of the living and the dead is crucial in forensic dental examinations. Age determination plays a significant role in forensic odontology, particularly in relation to identifying bodies and crime investigation. Teeth serve as the primary means of identification when external features do not provide sufficient information. Various methods for estimating age at death in adults have been introduced, including cementum annulation and dentin translucency. This study compared the accuracy of these two methods and found that dentin translucency age estimation is more precise than cementum annulation in the general population. It is recommended to use cementum annulation for younger adults (15-44 years) and dentin translucency for older individuals (>= 45 years).

Summary: An age-at-death estimation method using the first rib is advantageous due to its easy identification, low susceptibility to postmortem damage, and less mechanical stresses compared to other indicators. This study developed and tested such a method using a modern black South African sample of 260 skeletons, creating multiple linear regression equations for male, female, and combined samples. When tested on a hold-out sample, the equations generated mean inaccuracies of 7-13 years for point estimates. While the 95% confidence intervals contained the true age in 11-33% of individuals depending on the equation used, wider intervals generated using 95% prediction intervals contained true ages for 100% of individuals. Point estimate inaccuracies are comparable to other methods, but combined methods using indicators from multiple areas of the skeleton are preferred to reduce interval widths.

Summary: The London Atlas, a dental development chart, has gained notoriety in forensic scenarios. A systematic review and meta-analysis were conducted to determine the deviation between real and estimated ages when using the London Atlas method in sub-adults. The meta-analysis showed that the London Atlas is an accurate age estimation method, with a slight tendency to overestimate age.

Summary: This study examines the early growth trajectories of the trabecular bone structure of the humerus in Neandertals and modern humans, finding that their microstructural changes during early ontogeny are similar. Neandertals and modern humans share predetermined early growth trajectories and developmental mechanisms.

Summary: The paper discusses the importance of childhood in the modern human life history, reassessing a diagnosis of a rare genetic disease in an early human infant fossil and suggesting a more cautious approach to diagnosing pathologies on fossils. By comparing the dental development of the fossil with other hominins, the implications for the emergence of childhood in early Homo are also discussed.
