| Sumario: | • The present study examined 196 CT images of alive Greek patients. • The ossification of medial clavicular epiphysis was classified according to the Schmeling et al. and the extended Kellinghaus et al classification. • When the medial clavicular epiphysis is scored in stages 4 and 5, in both Greek sexes, the cumulative probability of adulthood (≥18 years) is nearly or 1. • For Greek males in stage 3c, the cumulative probability of adulthood is 0.857, and for Greek females in stage 3c, it is 0.968. • Detailed tables and graphs for stage and substage relation with age are provided for the whole male and female Greek population. Examining the clavicle by macroscopic or radiologic techniques is a well-established method in forensic age estimation in living and dead individuals. The present study examined 196 CT (computed tomography scan) images of native patients from the archive of the medical imaging laboratory of the University Hospital in Heraklion, Crete, in Greece. The ossification of the medial clavicular epiphysis was classified according to Schmeling et al. and the extended amplified staging system of Kellinghaus et al. Next, a stage transition analysis was carried out according to the Bayesian model. Probability density functions were calculated using informative priors for age distribution in the total population, deceased and violently deceased individuals. Our study showed that when the medial clavicular epiphysis' ossification is sorted in stages 4 and 5 in Greek males and females, the cumulative probability of adulthood (≥18 years) is nearly 1. As far as Greek males are concerned, in stage 3c, the cumulative probability of adulthood (≥18 years) is 0.86, and in Greek females in stage 3c, the cumulative probability of adulthood (≥18 years) is 0.97. This is the first study of age estimation based on the ossification of the sternal clavicular end using CT in a Greek population.
