Digitally reconstructing teeth: Novel strategy in forensic settings

A new digital technique involving micro-computed tomography could help overcome challenges related to thermal or physical fragmentation and improve dental identification.

In a study published in Forensic Imaging, researchers analyzed the efficacy of micro-CT in the digital reconstruction of 32 extracted anterior teeth and premolars. They scanned the intact teeth before mechanically fragmenting and digitally reconstructing them using an iterative closest point algorithm.

Between two operators, the researchers noted minimal bias and high reproducibility. The findings demonstrated the accuracy of the micro-CT-based approach in the digital reconstruction of the fragmented teeth.

Despite the positive results of the study, the researchers emphasized the need for further studies to validate whether the novel approach offers accurate dental reassociation with teeth that have undergone thermal or physical trauma.
