“…Estudios como el de Mustafi et al . 27 respaldan lo mencionado, ya que ellos observaron 120 CBCT de 60 hombres y 60 mujeres a quienes se les midió los diámetros transversal y sagital, así como también la circunferencia del foramen magnum . Obtuvieron diferencias notables entre los diámetros transversales y las circunferencias de la estructura anatómica entre hombre y mujeres, mientras que, con relación al diámetro sagital, no encontraron diferencias notables entre un sexo y otro, lo que demuestra la utilidad e importancia del uso del CBCT en la estimación del sexo para un antropólogo y odontólogo forense.…”

Objetivo: Describir el uso de las modalidades diagnosticas pertenecientes a la imagenología dentofacial en la odontología forense. Materiales y métodos: Se realizo una búsqueda en la base de datos de PubMed, Google Académico y SciELO con las palabras clave “Dentofacial imaging”, “Panoramic Radiography”, “Lateral Cephalogram”, “Cone Beam Computed Tomography (CBCT)”, “Digital Radiography”, y “Forensic Dentistry”. Se seleccionaron 48 artículos publicados en ingles, de fechas recientes, buscando información que describiera el uso de las modalidades diagnosticas pertenecientes a la imagenología dentofacial en la odontología forense. Resultados: Las modalidades diagnosticas de la imagenología dentofacial incluyen dentro de las más relevantes para la odontología forense la radiografía panorámica, la radiografía lateral de cráneo, la radiografía posterioanterior de cráneo y la tomografía computarizada de haz cónico. Conclusiones: Estas modalidades, junto a la ejecución de análisis morfométricos, permiten al odontólogo forense la identificación de un cadáver, la estimación de la edad, el sexo e incluso la reconstrucción facial forense con fines identificativos.

“…The aim of this study is to explore the morphological variations of the TMJ components in our ethnic group using CBCT imaging. By doing so, it seeks to contribute to the broader understanding of TMD and its management, as well as to the forensic applications of TMJ imaging for personal identification [ 15 ].…”

Introduction:The human mandible plays a significant role in personal identification due to its unique morphological characteristics. The coronoid process, condyle, and sigmoid notch exhibit variations that can be utilized for forensic and anthropological purposes. This study aims to analyze the morphological diversities of these mandibular features in our ethnic group using cone beam computed tomography (CBCT) imaging.Materials and methods: A retrospective analysis was conducted using 100 CBCT images obtained from the archives of the Department of Oral Medicine and Radiology. The images were captured using Carestream 9600 machines (Carestream Dental LLC, Atlanta, GA) with standard exposure parameters. Curved slicing screenshots were utilized for tracing the morphological variations of the coronoid process, condyle, and sigmoid notch.Results: Out of 100 CBCT images analyzed (corresponding to 200 sides), the shape-wise distribution of the coronoid process revealed that a triangular shape was most commonly observed in 59% (118) of cases. The condyle exhibited a predominantly round shape in 38.7% (77) of cases based on shape parameter-wise distribution. Similarly, the sigmoid notch displayed a round shape in 40.5% (81) of cases based on shapewise distribution.Conclusion: Personal identification using radiographs has gained significance in the current scenario due to its feasibility. Cone beam computed tomography imaging has become a reliable and accurate method for revealing hidden details in forensic odontology, especially when antemortem records are available. This research sheds light on the morphological variations of the mandibular coronoid process, condyle, and sigmoid notch within our ethnic cohort, enhancing personal identification practices. Further research encompassing larger sample sizes and diverse populations would enhance the applicability of these findings in forensic and anthropological contexts.

Background. This study aims to evaluate the accuracy rate of foramen magnum dimensions in determining sex among the South Indian population using discriminant functional analysis. Methods. An observational study in which CBCT images from 200 full field of view (FOV) scans were analysed. The dimensions of the foramen magnum were measured. Intra‐ and interobserver reliability were calculated. Independent t‐tests were used to compare the various parameters between sexes. Stepwise discriminant function analysis was used to determine sex. Results. A total of 200 CBCT scans were included in the study. The mean age (±SD) was 25.66 (±7.11) years among males and 24.64 (±5.12) years among females. The measurements and the circumference of the foramen magnum were significantly (p < 0.001) greater in males than in females. The univariate analysis of foramen magnum measurements reached an accuracy rate of 73.5% in sex determination. The discriminant function analysis combining the foramen magnum measurements and circumference yielded an overall predictability rate of 66.5% for determining sex. Conclusion. Taking into account the predictability rate of sex based on foramen measurement in the present population, it can be concluded that its applicability should be limited to cases associated with fragmentary skull bases.
