Micro-computed tomography (micro-CT) can accurately reconstruct fragmented teeth, producing models that differ from intact specimens by just 0.01 to 0.02 mm. In a study involving 32 extracted human teeth, researchers demonstrated the method's precision and reproducibility in geometric assessments, revealing a mean deviation of 0.012 mm by one operator. The approach showed strong agreement in measurements and retained internal structures. Despite limitations regarding the types of teeth studied and accessibility of micro-CT technology, its potential for forensic applications is notable, as emphasized by lead author Amaury Paring from Université Paris Cité.
