“…However, we consider it necessary to include only adults in the analysis of osteological material. This is because firstly, the sternum develops until early adulthood, approximately between 16 and 18 years of age (Shedge et al, 2021). Although the mechanism of postnatal sternal development has been well described (Weaver et al, 2014), we do not yet have a longitudinal study to show whether and to what extent the relative shape of the bone remains unchanged during development.…”

“…However, with the advancement of age, these skeletal and dental indicators are of limited utility in age estimation practices. In such a scenario, age can be estimated from the epiphyseal fusion of the medial end of the clavicle, the fusion of the sternum, pubic symphyseal changes, and obliteration of cranial sutures [3,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”

“…Imaging modalities, such as computed tomography (CT), allow scientists to examine age-related changes in cranial sutures in living people. CT allows for rapid processing and faster investigation and imparts clarity in assessing these changes [6,7,22,36]. A thorough literature search indicates that there is limited research on the 3D CT-based technique of age estimation using cranial sutures in the Indian population [27].…”

Background: Age estimation is a critical aspect of human identification. Age is assessed using cranial suture obliteration, pelvic morphological changes, epiphyseal fusion of long bones, dental maturation, and other standard methods.Methods: The present study investigated three-dimensional (3D) computed tomography (CT) scans of 263 individuals (183 males and 80 females) to assess the extent of ectocranial suture closure. The assessment of obliteration was done using a three-stage scoring method. Spearman's correlation coefficient (p < 0.05) was calculated to assess the relationship between cranial suture closure and chronological age. Simple and multiple linear regression models were developed using the cranial suture obliteration scores to estimate age.Results: The standard errors of the estimate using multiple linear regression models developed for estimating age using obliteration scores of sagittal, coronal, and lambdoid sutures were 15.08 years in males, 13.27 years in females, and 14.74 years in the total study population. Conclusion:This study concludes that in the absence of additional skeletal age markers, this method can be used alone or in conjunction with other well-established methods of age assessment.

“…4 Morphological changes ensuing within bony surfaces, and/or ossification and fusion of bones have often been employed to ascertain age-at-death of individuals. [5][6][7][8][9][10][11][12] The pelvis is of particular importance as it exhibits significant age-dependent developmental, as well as, degradative changes, allowing for age estimation across a broader age cohort. 5,9,11,[13][14][15][16][17][18] Within the pelvis, more commonly researched parameters are the pubic symphysis, and the auricular surface of the ilium.…”

McKern-Stewart method as a technique for analysing age related pubic symphyseal changes: A systematic review and meta-analysis

Age estimation is one of the essential criteria in the identification process. The method of age estimation employed depends on the availability of skeletal material brought for forensic examination. McKern and Stewart's method constitutes one of the principal approaches towards pubic symphyseal age estimation. The method entails evaluating morphological changes within the pubic symphysis and subsequently allotting a specific score corresponding to the observed changes. Based on the obtained scores, an age range is then assigned to the remains presenting for examination. The present systematic review was undertaken to ascertain the applicability of the McKern-Stewart method for age estimation. Studies pertaining to the use of the McKern-Stewart method for age estimation in skeletal remains were retrieved by keying in a combination of MeSH terms and other free terms from four databases. The retrieved articles were subjected to a stringent inclusion and exclusion criteria, following which the risk of bias was assessed and the overall quality of evidence was established. Once the final tally of relevant articles was obtained, data specific to the mean age corresponding to each score was extracted. Non-parametric tests and boxplots were employed to compare the mean ages reported across multiple studies. The present systematic review concludes that the McKern-Stewart method can be applied for the purpose of age estimation in skeletal remains. Broader age cohorts for higher scores, as well as, overlapping values for age ranges in relation to the cumulative scores, however, can be considered a limitation for its applicability in forensic case work.
