“…The technological development of image acquisition methods in the healthcare area has favoured the scientific innovation by enabling studies and analyses to benefit from the copious source of information on human body [6,18]. CBCT provides richly-detailed images and, as a result, a series of anatomical regions can be studied and interpreted objectively and in detail.…”

“…In the process of human identification, the determination of gender and age is a key step for establishing a biological profile, which is essential to reduce the sample to a lower number of possible identities [5,6]. However, this procedure is challenged with situations in which there are a few bone fragments or remnants of pelvis or skull [3,5,6].…”

“…However, this procedure is challenged with situations in which there are a few bone fragments or remnants of pelvis or skull [3,5,6]. In this context, research on forensic dentistry and anthropology have associated the use of image technology to the study of bone anatomy for obtaining clues which can guide the estimation of gender and age in such situations [6][7][8].…”

“…In this way, CBCT has been widely used as it allows three-dimensional visualisation of the anatomical shape, relationship and position of a series of bone structures and cavities by providing detailed images with minimum distortion, which enables a more reliable study of the bone morphology and morphometry [2,3,6].…”

“…Although there are considerably reliable methods for estimation of gender [8,15] and age [16,17] using dental and osseous elements, it is necessary that other methodologies be proposed to aid in cases of dental absence or bone fragmentation resulting of severe traumas, such as mass accidents and explosions [5][6][7]. Therefore, the present work was aimed at using CBCT to measure the opening diameter of incisive foramen and to analyse its correlation as a parameter for gender and age estimation.…”

Objective: To analyse the opening diameter of incisive foramen as a parameter for gender and age estimation by using cone beam computed tomography (CBCT). Material and Methods: After approval by the local research ethics committee, CBCT images were obtained from the dental database of a diagnostic centre and then selected. Images suggesting presence of periapical lesions and periodontal changes were excluded, as well as those of patients undergoing orthodontic treatment, with trauma to the mid-facial third, with cleft/lip palate, cranial or syndromic morphological changes, or even absence of one of the upper incisors. The images of male and female patients were distributed according to age groups (i.e. 10-30 years, 31-50 years, and 51 years or older) and then assessed twice and independently by three surgeon-dentists with experience in radiology by means of the XoranCat® software. The resulting data were tabulated and statistically analysed by using the SAS® software (version 2003) – PROC GLM for mixed generalised models – and Tukey’s test for comparison of the mean values at 5% significance level. Results: Considering the methodology used, the results have demonstrated no statistically significant difference in the method for gender estimation. However, it was observed that there was a gradual increase in the mean values as the age advances in the majority of the age groups for both males and females, with a statistically significant difference (P<0.05) regarding age estimation. Conclusion: The use of incisive foramen as a gender parameter has had a limited forensic value, but it is an innovative approach in the process of age estimation.KeywordsDentistry; Human identification; Anatomy; Computed tomography.

Background Estimation of sex of the skeletal remains plays a vital part in the identification of an individual. This study is focused on the morphometric measurements of the foramen magnum region and examining the accuracy of sexual dimorphism in the Nepalese population. Methods Measurements were obtained from 3D computed tomography (CT) scan of 261 Nepalese adult cranial bases with known age and sex. Length and breadth of the foramen magnum, length and breadth of right and left occipital condyles and maximum and minimum intercondylar distance were measured on the base of the skull CT images. Results The mean values for all parameters were higher in males than females except for the maximum intercondylar distance. Sex prediction done with discriminant function analysis could classify the skull with an overall accuracy of 70.5%–71%. Conclusions It can be concluded from the results that the morphometric study of the foramen magnum is less reliable for sex estimation in the Nepalese population.
