- Forensic odontology primarily involves the use of dental knowledge to aid legal investigations.
- One key application is the determination of age from dental records, teeth development, and eruption patterns, especially in unidentified bodies or living individuals with unknown age.
- This is crucial in establishing identity or legal status.
- Other options like diagnosis or treatment focus on clinical dentistry, not forensic purposes.
