Dental records from cone beam computed tomography (CBCT) and panoramic radiographs (PR) are equally effective for human identification. Key dental identifiers, especially for third molars, are reliably found in both imaging types.
Area of Science:
- Forensic Odontology
- Radiology
- Human Identification
Background:
- The INTERPOL standard provides a scientifically reliable method for human identification using dental records.
- Comparing antemortem and postmortem dental data is crucial for accurate identification.
- Cone beam computed tomography (CBCT) and panoramic radiographs (PR) are common dental imaging modalities.
Purpose of the Study:
- To quantify and compare the prevalence of INTERPOL-coded dental identifiers in CBCT scans and PR.
- To assess the reliability and interchangeability of dental identifiers between CBCT and PR for human identification.
Main Methods:
- A sample of 100 CBCT scans and 100 PR from the same patients was analyzed.
- Forty-one INTERPOL-coded dental identifiers were independently assessed in each imaging type.
- Statistical analyses included Wilcoxon tests, Chi-square tests, and multiple correspondence analyses (MCA).
Main Results:
- No statistically significant differences were found in the prevalence of INTERPOL dental identifiers between CBCT scans and PR (p=0.693).
- A significant dependence was detected between specific teeth and dental codes in both imaging modalities (p<0.05).
- The strongest associations were observed between codes for unerupted, partially erupted, and impacted teeth (UNE, ERU, IMV) and third molars in both CBCT and PR.
Conclusions:
- INTERPOL-coded dental identifiers are reliably represented in both CBCT scans and PR.
- Data from CBCT scans and PR are interchangeable for human identification purposes.
- The findings support the consistent application of INTERPOL coding in forensic odontology using different radiographic techniques.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
