A forensic odontologist is asked to identify severely burnt remains where dental records are unavailable, but antemortem sinus radiographs exist. Which radiographic structure is MOST reliable for positive identification?
- A Maxillary sinus morphology
- B Mastoid air cell system
- C Frontal sinus pattern ✓
- D Sphenoid sinus configuration
Correct answer: C. Frontal sinus pattern
Explanation
The frontal sinus pattern is unique to each individual, including identical twins, and remains stable after reaching full size in early adulthood. It is the MOST reliable radiographic structure for identification when dental records are unavailable. Maxillary sinuses are more symmetrical and less distinctive. Mastoid and sphenoid sinuses show less individual variation.
