Abstract

When conventional identification methods are compromised, the comparative study of dental images proves to be effective in human identification. This study reports a human identification case using the comparison of ante-mortem radiographs with post-mortem mandibular computed tomography. A male body found in an advanced decomposition stage was sent to the Scientific Police Institute of João Pessoa/PB, Brazil. Fingerprinting and facial recognition were not feasible due to the destruction of digital pulps and severe epidermal damage. Therefore, the forensic dentist decided to enucleate the mandible to obtain computed tomography images for comparison with an ante-mortem panoramic radiograph provided by a victim's relative. The images were essential for studying and comparing the anatomy of the mandibular structures, such as the mandibular canal, as well as the positioning and angulation of the dental roots. The comparison between ante-mortem dental radiographs and post-mortem computed tomography revealed sufficient concordant features for a positive identification.
