    Micro-CT enables highly accurate digital reconstruction of fragmented teeth, with deviations of approximately 0.01 mm to 0.02 mm between operators.

    In a study, 32 extracted human anterior teeth and premolars were evaluated, demonstrating the feasibility of micro-CT for forensic dental reconstruction.

  • 3

    The mean deviation between reconstructed and reference meshes was 0.012 mm for the first operator and 0.017 mm for the second operator.

    Micro-CT captures both external morphology and internal structures, offering advantages over optical surface scanning in forensic applications.

  • 5

    Despite its potential, micro-CT's broader implementation in forensics requires further validation, especially for damaged specimens.
