What the literature leaves open

  • The period between 30 and 45 years of age is considered the age group with the highest mortality among ancient males at archaeological sites, both during Antiquity in Croatia and in other countries, although the exact reason for this remains unknown.

  • Second, the model relies exclusively on skull geometry and does not incorporate additional biological or demographic information, such as age, sex, ancestry, body size, or body mass index, which may contribute to uncertainty in soft-tissue-dominant regions; future work may investigate the incorporation of such information when it is available and forensically justified.

  • Regions reconstructed with higher accuracy may be considered more reliable during interpretation, whereas under-constrained regions should be approached with explicit awareness of their inherent uncertainty.

    Can vision-language models estimate patient age? evidence from panoramic radiographs · 2026 · DOI

  • Their evaluation may improve clinical decision-making and treatment planning by assisting in determining whether craniofacial growth has been completed and better estimating residual growth potential, particularly in orthodontic and orthognathic treatment planning, as well as in cases where dental age estimation is insufficient to accurately assess skeletal maturation.

    Association Between the Spheno-Occipital Synchondrosis and Mandibular Condyle Periphery Maturation in Relation to Chronological Age · 2026 · DOI

  • Besides the advantages of the virtual technologies, their use does not completely overcome some ethical and legal issues considering the still open questions about the use and the fate of the anthropological ‘digital twins’ (Italian term commonly used to refer to digitized items, meaning digital replicas), due to the absence of ethical and legal frameworks to date.

    The Digitization of Human Skeletal Collections: New Challenges and Perspectives · 2025 · DOI

  • Because of the limited availability reported data, few studies have examined the distribution of FT number variations by sex and laterality., the presence of additional foramina in the transverse processes may suggest a multiplication of vascular structures passing through them, although the clinical significance of this remains uncertain.

  • In the light of broadening of the topic of subadult stress in Antique Panonnia, future research should focus on multidisciplinary approaches by integrating osteological data with isotopic analyses in order to reconstruct dietary patterns and mobility.

    Periostitis as an Indicator of the Impact of Subadult Stress: An Analysis of Late Antique Sites in Southern Pannonia · 2026 · DOI

  • Future research should focus on validation using larger and more heterogeneous datasets, including multi-center data and real longitudinal examinations.

  • Although the cause of morphological variability of cervical vertebrae has not been fully clarified, it has been determined that there is a genetic predisposition.

    Prevalence of the Arcuate Foramen: A Comparative Study Between a Chalcolithic and a Contemporary Iberian Peninsula Sample · 2025 · DOI

  • However, the specific ways in which various factors influence the distal limbs, and the methods to assess the degree of their impact, remain insufficiently explored.

    The Contribution of the Distal Limbs to Height and Proportions in Different Socioeconomic Groups · 2025 · DOI

  • One limitation is that older adults or those with premature dentine apposition may exhibit pulp cavities that have receded (apically) beyond the coronal half of the tooth.

    Exploring optimal methods for age-at-death estimation using pulp/tooth area ratios: a South African study · 2024 · DOI

  • Although humeral bowing is well known, the character and magnitude of this bow have not been studied.

    An Anatomic Study of Normal Humeral Shaft Bowing · 2026 · DOI

  • Although their precise dating remains uncertain, the funerary practices documented, and the associated cultural materials indicate that both contexts can be attributed to the Late Holocene.

    Prácticas funerarias de cazadores-recolectores terrestres en la zona de los morros (Santa Cruz, Argentina – Magallanes, Chile): una evaluación desde la arqueotanatología · 2026 · DOI

  • Despite the increasing use of radiological techniques in forensic anthropology, relatively few studies have developed reliable models for sex estimation using cranial measurements obtained from non-invasive imaging modalities.

    Machine learning-driven forensic sex prediction using CT-based nasal and maxillary sinus metrics · 2026 · DOI

  • Regarding this lower age limit, there is no standardized minimum age recommended for performing panoramic radiographs; rather, the decision should be made based on several factors.

    Evaluating the Nolla Method for Dental Age Estimation in Children from Northwestern Romania · 2025 · DOI

  • Nevertheless, the correlation between annual income and EH is not unequivocal, and comparisons with other studies should be approached with caution, as income threshold and reporting standards vary widely.

    Investigating the Etiology and Demographic Distribution of Enamel Hypoplasia · 2025 · DOI

  • This study investigated thoroughly the application of DSP2 to a Spanish dry skeletal sample. Percentage of sexing was high when 10, first 8 or 4 best variables were considered and reduced to half when the 4 variables with least discrimination power, called worst 4 variables, were utilized.

    Application of DSP2 for biological sex estimation in a Spanish sample: analysis based on sex and side · 2024 · DOI

  • For both sexes, the growth spurt is more intense and occurs later for Class I than for Class II, although the evidence remains inconclusive.

    Studying the dynamics of mandibular growth spurts in individuals with Class I and Class II skeletal growth patterns using the Bayesian superimposition by translation and rotation (SITAR) model · 2025 · DOI

  • Socioeconomic information was unavailable; therefore, potential access-related or environmental modifiers could not be evaluated directly.
