“…32 As the human body matures, the pubic symphysis undergoes biomechanical, 41 degenerative, 39 and morphological changes. 19 In addition, anatomical differences exist between male and female pelves with the female symphysis being somewhat shorter and broader than that of the male. 32 These gender differences have been shown to affect joint mechanical properties.…”

Three-dimensional finite element (FE) models of human pubic symphyses were constructed from computed tomography image data of one male and one female cadaver pelvis. The pubic bones, interpubic fibrocartilaginous disc and four pubic ligaments were segmented semi-automatically and meshed with hexahedral elements using automatic mesh generation schemes. A two-term viscoelastic Prony series, determined by curve fitting results of compressive creep experiments, was used to model the rate-dependent effects of the interpubic disc and the pubic ligaments. Three-parameter Mooney-Rivlin material coefficients were calculated for the discs using a heuristic FE approach based on average experimental joint compression data. Similarly, a transversely isotropic hyperelastic material model was applied to the ligaments to capture average tensile responses. Linear elastic isotropic properties were assigned to bone. The applicability of the resulting models was tested in bending simulations in four directions and in tensile tests of varying load rates. The model-predicted results correlated reasonably with the joint bending stiffnesses and rate-dependent tensile responses measured in experiments, supporting the validity of the estimated material coefficients and overall modeling approach. This study represents an important and necessary step in the eventual development of biofidelic pelvis models to investigate symphysis response under high-energy impact conditions, such as motor vehicle collisions.

“…In forensic science, anthropology, and archaeology, many studies deal with the estimation of chronological age in humans, but few are devoted to studying the accuracy and reliability of the results. The most widespread methods for age estimation are based on skeletal indicators such as epiphysial fusion [1][2][3], hand-wrist bones [4][5][6][7][8], changes in the pubic symphysis [9][10][11][12], fusion of cranial sutures [12,13], dental maturation [14][15][16][17][18][19][20][21][22], and combined method [23].…”

In forensic science, anthropology, and archaeology, several techniques have been developed to estimate chronological age in both children and adults, using the relationship between age and morphological changes in the structure of teeth. Before implementing a statistical model to describe age as a function of the measured morphological variables, the reliability of the measurements of these variables must be evaluated using suitable statistical methods. This paper introduces some commonly used statistical methods for assessing the reliability of procedures for age estimation in the forensic field. The use of the concordance correlation coefficient and the intraclass correlation coefficient are explained. Finally, some pitfalls in the choice of the statistical methods to assess reliability of the measurements in age estimation are discussed.

“…Age-at-death estimates are vexing because they try to correlate physiological age and chronological age in a system that has differential development and deterioration. Variation in development and deterioration of the skeletal system differs among individuals as well as across populations and between the sexes (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). Differences can be attributed to socioeconomic status, cultural differences, genetic differences, differences in behavior, environmental factors, diet, and disease (16,21).…”

The present study analyzed apical translucency and periodontal recession on single-rooted teeth in order to generate age-at-death estimations using two inverse calibration methods and one Bayesian method. The three age estimates were compared to highlight inherent problems with the inverse calibration methods. The results showed that the Bayesian analysis reduced severity of several problems associated with adult skeletal age-at-death estimations. The Bayesian estimates produced a lower overall mean error, a higher correlation with actual age, reduced aging bias, reduced age mimicry, and reduced the age ranges associated with the most probable age as compared to the inverse calibration methods for this sample. This research concluded that periodontal recession cannot be used as a univariate age indicator, due to its low correlation with chronological age. Apical translucency yielded a high correlation with chronological age and was concluded to be an important age indicator. The Bayesian approach offered the most appropriate statistical analysis for the estimation of age-at-death with the current sample.
