Positive dental identification using tooth anatomy and digital superimposition

Area of Science:

• Forensic Odontology
• Digital Imaging in Forensics

Background:

• Dental identification remains crucial in forensic investigations, complementing DNA analysis.
• Destructive incidents often render human remains unrecognizable, necessitating alternative identification methods.
• Antemortem records of dental and osseous characteristics are vital for conclusive victim identification.

Observation:

• This case report details the use of digital comparative analysis for dental identification.
• Antemortem dental models were digitally analyzed using Adobe Photoshop software.
• Individual tooth anatomy and digital superimposition were employed for comparison.

Findings:

• The digital comparative analysis of antemortem dental models and postmortem dentition proved effective for positive identification.
• This method was particularly useful in the absence of antemortem radiographs.
• The technique allowed for detailed comparison of tooth anatomy between records.

Implications:

• Digital comparative analysis provides a valuable tool for forensic identification when conventional methods are limited.
• This approach enhances the ability to identify victims of accidents and homicides.
• The use of readily available software like Adobe Photoshop democratizes advanced forensic techniques.
