“…Actualmente, dado que el uso de CBCT está en un aumento constante en el campo dental, hay una mayor disponibilidad en casos que requieren identificación ósea del sexo. Por lo tanto, es probable que estos datos también sean más accesibles en el área odontológica, que necesita registros dentales para una determinación dental 15,16 . Trochesset et al 17 concluyeron que las imágenes CBCT permiten la comparación y la identificación forense dental mejor que la tomografía médica para este propósito [15][16][17] .…”

si el dismorfismo sexual de las medidas métricas del foramen magno podrían determinarse usando la modalidad de imagen CBCT. Método: Estudio con diseño transversal en el que se evaluaron 385 imágenes CBCT que cumplieron con los criterios de selección. Se midieron la longitud máxima, el ancho máximo y el área del foramen magno mediante las fórmulas de Routal y de Teixeira. Resultados: El presente estudio demuestra que utilizando tanto Routal (0.687) como Teixeira (0.688) se logra una confiabilidad del 69% en la estimación del sexo de un cráneo. Conclusiones: Este estudio valida la medición digital de la superficie del foramen magno obtenida de CBCT, siendo una herramienta a usar en la definición del sexo a través del macizo craneofacial. Es definitiva si se obtienen extremos, pero necesitará el estudio de otra estructura cuando presente valores intermedios.

“…As the dental records are typically in 2D format, it is sufficient; albeit it is not necessary to give up of the advantage of 3D reconstructed matching to the 2D image. The reconstruction of skeletal remains using conventional CBCT provide accurate three-dimensional reconstructions, which demonstrate its reliable use as a forensic tool [28].…”

(1) Human teeth are the most resilient tissues in the body. However, exposure to concentrated acids might lead to their obliteration, thus making human identification difficult. Teeth often contain dental restorations from materials that are even more resilient to acid impact. This paper introduces novel method of 3D reconstruction of dental patterns as a crucial step for digital identification with dental records.; (2) With combination of modern methods of Micro-Computed Tomography, Cone Beam Computed Tomography, Attenuated Total Reflection in conjunction with Fourier-Transform Infrared Spectroscopy and Artificial Intelligence Convolutional Neural Network algorithms, the paper presents the way of 3D dental pattern reconstruction and human remains identification. Research studies morphology of teeth, bone and dental materials (Amalgam, Composite, Glass-ionomer cement) under different periods of exposure to 75% sulfuric acid; (3) Results reveal significant volume loss in bone, enamel, dentine and as well glass-ionomer cement. Results also reveal significant resistance of composite and amalgam dental materials to sulfuric acid impact, thus serving as strong parts in the dental pattern mosaic. Paper also introduces probably first successful artificial intelligence application in automated forensic CBCT segmentation.; (4) Interdisciplinary cooperation utilizing mentioned technologies can solve problem of human remains identification with 3D reconstruction of dental patterns and their 2D projections over existing ante-mortem records.
